Do You Need a Sleep Reset?

Why is sleep so important for good health? Our guest is a sleep medicine specialist who uses a metaphor of Disneyland. Crucial maintenance on the theme park happens at night, when there are no visitors. Streets are cleaned, flower beds are weeded, and rides are inspected and, if needed, repaired. None of that can happen while the park is open for business. Our bodies and brains also need time for maintenance and repair, and some of that happens while we are sleeping. When we don’t get the rest we need, we may find ourselves at increased risk for diabetes, cardiovascular problems, cancer, cognitive challenges and even premature death.

Unfortunately, anxiety about not sleeping can keep people awake all on its own. How can people break that cycle? We’ll also discuss ways that people can get help avoiding screens at night. That is an important part of a sleep reset. Blue light from the screen signals the brain to be alert instead of relax. Scrolling social media can often be emotionally upsetting, which also makes it more difficult to fall asleep.

Is Your Diet Keeping You Awake?

Most of us recognize that a big midnight snack, á la Dagwood Bumstead of the Blondie comic, is probably not conducive to sleeping well. How does nighttime eating affect our circadian rhythm? Are there diets that we should avoid because of their impact on sleep? Dr. Seheult describes a study in which volunteers had their sleep stages monitored closely during the time they were consuming different diets (Obesity, July 2023). When they followed a high-fat, high-sugar diet, it disturbed the pattern of their brain waves during what should have been restorative sleep.

How Do Sleep Problems Affect Eating Habits?

A lot of us are aware that when we are sleep deprived, we are more inclined to become hangry and we may be less discerning about what we eat. A recent study shows that the sleep deprivation can have an effect even if it is fairly mild and short-term. Scientists recruited people who normally sleep seven to eight hours a night and asked them to stay up an extra hour and a half (Annals of Internal Medicine, July 7, 2026).  During the six weeks of that part of the experiment, people were less active during the day. They also ate more, so they gained about a pound, on average, during those six weeks. Presumably, disrupting sleep for a longer period of time would result in greater weight gain and metabolic disruption.

Would a Ketogenic Diet Help with a Sleep Reset?

A ketogenic diet, in which the body relies on ketones rather than glucose for energy production, may be helpful. In particular, fasting overnight for at least 14 hours helps the body do what it must during sleep time. To figure out when you should stop eating, identify when you usually start to feel sleepy. That should be your bedtime. Having your last meal of the day about three hours before that will generally offer enough time for digestion so that you don’t experience reflux in the middle of the night.

Morning Light and Afternoon Naps

Your sleep reset may depend on getting your own circadian rhythm to synchronize with the rest of the world. That is where early exposure to morning light comes in. It’s beginning to feel a bit like The People’s Pharmacy is on repeat: get morning light exposure! It sets your system up for feeling awake and alert during the day and starting to feel sleepy as the light fades in the evening. Obviously, this is most helpful for people who work during daylight hours. Those working overnight shifts would have to organize their days differently.

People who have trouble falling asleep may be tempted to take a nap in the afternoon to make up for the lost sleep. That could be a mistake, as it relieves the sleep pressure that helps people fall asleep without trying.

Learning to Fall Asleep

If you interact with parents of very young children, you may have heard of sleep training. People have strong feelings about this, both pro and con. Adults rarely need sleep training, though. What we are more likely to need is “not-sleeping un-training.” Too many people approach the bedroom as though it were a stage, and sleep is the performance. No wonder they may develop some performance anxiety about sleeping! Other individuals have learned to associate the bedroom with tossing, turning and watching the clock. Consequently, their bodies tense up instead of relaxing when they get between the sheets. There is no easy quick fix for this problem, but cognitive behavior therapy for insomnia has been proven effective for most people.

How About PM Pain Relievers?

Even though there isn’t an easy fix for sleep troubles, many people want one. They reach for the PM pain reliever and hope it will offer them a good night’s sleep without a prescription.

The “PM” part of that pain reliever is an old-fashioned antihistamine called diphenhydramine. You might be more familiar with its brand name: Benadryl. You’ll also find it in Tylenol PM, Advil PM and all the other PM meds because it tends to make people feel drowsy.

What’s wrong with that? To start with, it isn’t clear that it remains effective after a week or two. In addition, people with restless leg syndrome often find that it makes their condition worse. Other folks report that diphenhydramine can result in an unpleasant “hangover” the next day, in which they feel drowsy though not asleep for a good part of their waking hours.

What Wakes You Up at Night?

If your sleep problem is waking in the wee hours and having trouble getting back to sleep, you should consider the possibility that you have sleep apnea. The REM sleep of those early morning hours is not as deep as some other sleep stages. Consequently, an alarm signal from your brain saying you haven’t taken a breath for 20 or 30 seconds may be more likely to wake you. Sleep apnea may be treated by providing air so that the pressure props the collapsing airway open. We discuss this in greater detail along with a new alternative to a CPAP machine in the podcast for this week.

When sunny summer days come around, it makes some dermatologists shudder. They would prefer we behave like bats and hide in caves until nightfall. Failing that, they stress the importance of always applying (and re-applying) high SPF sunscreen, wearing sun-blocking clothing with long sleeves and keeping a big-brimmed hat firmly on the head. A beekeeper’s outfit might be perfect. But must you really shun the sun completely to save your skin? Our guest describes how to practice moderation safely. He also explains why some people are addicted to sunshine, while others are allergic to it.

Can You Really Be Addicted to Sunlight?

Dermatologists do their best to discourage people from using tanning beds. They describe the damage that ultraviolet light can cause, ranging from wrinkles to skin cancer. For some people, though, those arguments just don’t make a difference. Our guest, Dr. Steve Feldman, conducted a study several years ago. The volunteers were accustomed to using tanning beds. In the study, there were two beds, one with the usual ultraviolet light and the other, identical in appearance and temperature, had its UV blocked. After a session in each bed, volunteers were allowed to choose their bed for the last session. They almost invariably chose the bed with the active UV.

To follow up, the researchers administered naltrexone, the opioid-blocking medication. When volunteers had taken it, they were no longer able to distinguish which bed was active. It seems that, for these people, ultraviolet light activates pro-opiomelanocortin, which in turn triggers the production of natural opioids called endorphins. Further research imaging the brain during tanning sessions confirmed that the UV exposure was activating areas of the brain associated with pleasure (Psychiatry Research. Neuroimaging, May 30, 2016).  Dr. Feldman and a colleague found that excessive indoor tanning is similar in pattern to substance use disorders (Journal of Cutaneous Medicine and Surgery, May-June 2025).

Can You Save Your Skin and Still Enjoy the Outdoors?

Dr. Feldman offers advice on avoiding sunburn that is tempered with this fact from epidemiology: people who go out in the sun live longer (International Journal of Environmental Research and Public Health, July 13, 2020).  The goal here is not to shun the sun completely, but rather to exercise enough caution and good judgment to avoid burning your skin. (Who wants to burn, anyway? It hurts, and it looks bad.) Timing your sun exposure carefully is crucial to save your skin from sunburn. You may also be interested in the new sunscreen ingredient the FDA just approved, bemotrizinol.

What Can You Do About Heat Rash?

When the weather gets hot and bodies get sweaty, heat rash becomes a common complaint. Sweaty skin may develop bumps that can sometimes be very itchy. What do you do to ease the discomfort? If you can cool the skin off, it might help a lot.

Of course, people may also suffer from other types of rash. Babies get diaper rash. Women sometimes experience under-breast rash, just as men may develop jock itch. Zinc oxide ointment can often be helpful for these types of rash.

Managing Psoriasis

Psoriasis is one of Dr. Feldman’s special research interests. The red scaly plaques of this skin condition have raised borders. They look a lot like a fungal infection, but there is no fungus present on the skin to cause them. Something else seems to trigger the skin’s immune system to react along the same pathways as if there were a fungus.

Most of the time, psoriasis is mild enough to manage without costly medications. It actually responds very well to ultraviolet light exposure. UV downregulates the immune system’s over-response. While many dermatologists offer UV exposure within their office walls, in the summertime patients could get exposure to sunlight outdoors. This is practical if they avoid the middle of the day, when they might get burned. Another option? Tanning beds also offer an easy way to calibrate the appropriate amount of UV exposure to save your skin from psoriasis. (Most dermatologists don’t approve of this one, so don’t tell.)

One other practical but unorthodox tip for dealing with mild psoriasis. OTC cortisone may not be strong enough to help heal up a red spot. But you could buy Flonase nasal spray or a generic version, fluticasone, over the counter. Spray it on your skin and appreciate the relief. In fact, this could work for a mild case of poison ivy or other skin irritation as well. Severe cases still need a dermatologist’s care.

What to Do About Atopic Dermatitis

Atopic dermatitis is the medical term for eczema. People with allergies or asthma also appear to be more vulnerable to eczema. Dysregulation of the immune mediators interleukin 4 (IL4) or IL13 may be responsible. This condition may appear in a mild form, which can be readily managed, or a more severe form that might require prescription medication. A topical corticosteroid such as triamcinolone will often clear it up. Or you could try spraying on some Flonase nasal spray for a cost-effective low-key approach. Those will actually help the majority of people with mild eczema. Using mild soap rather than detergent-based body wash, moisturizing well and following an anti-inflammatory diet are the pillars of home management.

People with more severe atopic dermatitis covering a large portion of the body may need powerful prescription medication rather than topical steroids. Trying to cover so much skin with steroid would probably result in side effects from the cream. Dupixent (dupilumab) is a relatively new self-injectable medication that blocks IL4 and IL13. It works well for most people with atopic dermatitis and has a good safety profile. Certain other drugs in this category, such as Skyrizi (risankizumab), are also pretty safe but very pricey. Stelara (ustekinumab), has been around longer. Biosimilars for Stelara have been approved and are more affordable. Ustekinumab blocks IL12 and IL23.

TV ads tout other medicines for this condition as well. Rinvoq (upadacitinib) is three or four times more effective than Dupixent, but it is also super expensive. It is a Janus-kinase (JAK) inhibitor. Xeljanz (tofacitinib) is another potent prescription JAK inhibitor, but it carries an elevated risk of heart attack.

Beware of Bug Bites

Another summer skin hazard is bug bites. Here unquestionably the best approach to save your skin is avoidance. Appropriate clothing is key. (That beekeeper’s suit will come in handy here again.) Dr. Feldman recommends spraying DEET on your pants legs, socks and sleeves rather than directly on your skin. If there are grasses or brush where you have walked, run or played, a tick check immediately upon coming inside is critical.

Can AI Help Patients with Skin Problems?

It doesn’t make sense to tell people to stay off the internet. Some searches can be quite helpful and guide patients in asking their dermatologist the right questions. Dr. Feldman is enthusiastic about DermNet, a New Zealand dermatology website. https://dermnetnz.org  Joe and Terry recommend SkinSight.

This week, we look at the new pharmaceuticals that the FDA has approved for treating Alzheimer disease. Although they are effective at removing amyloid plaques from the brain, they don’t seem to help patients function better. Is it time to turn away from an exclusive focus on amyloid to consider other factors that might affect cognitive decline and change the course of Alzheimer disease?

Changing the Course of Alzheimer Disease

Even though pharmaceutical firms have spent billions of dollars developing drugs to reduce amyloid in the brain, they haven’t changed the course of Alzheimer disease. Perhaps we need to be looking beyond amyloid at other risk factors. Dr. Dale Bredesen says he and his colleagues have identified more than 36 risk factors. He asserts that when these these are addressed, people can slow or sometimes even reverse their cognitive decline. According to Dr. Bredesen, Alzheimer disease is multi-factorial and it needs a multi-pronged approach.

Considering Physiology Instead of Pathology

The plaques and tangles that are characteristic of the brain disease first identified by Alois Alzheimer more than 100 years ago only show up in pathology slides. Past studies have hinted that some individuals who have plaques or tangles in their brains don’t have serious cognitive difficulties. Dr. Bredesen urges us to look beyond amyloid pathology and use a physiology lens. What are the main drivers of problems?

Energetics

Our bodies need to make, use and transfer energy efficiently. That involves the mitochondria, the energy factories within the cells. Nutrition is also critical here, as missing vitamins can block appropriate metabolism. The cardiovascular system is also crucial for the transfer of energy within the body and to the brain. Sleep apnea, which interferes with oxygen uptake overnight, is another big culprit.

Inflammation

Inflammation in the brain or even elsewhere in the body puts a huge strain on the neurons. Identifying and removing the sources of inflammation is important in treating someone struggling with cognitive problems. Where is the inflammation coming from? It might be an infection. Treatment can make a difference there. It might be dietary, in part. Changing the diet could change the course of Alzheimer disease. Wouldn’t that be worth the effort?

Toxicity

Heavy metals such as lead or mercury are definitely neurotoxic. However, other substances can also put neurons at risk. Toxins produced by mold are common and very difficult to treat.

Additional Factors to Consider

There are at least three additional categories that should be considered. Do we have the essential ingredients to create the neurotransmitters we need? One example would be choline for acetylcholine, an essential neurotransmitter that may be in short supply in Alzheimer disease. Most American diets are not rich in choline. Second, how are the neurotrophins doing? These are substances such as BDNF, brain-derived neurotrophic factor. It supports the growth and differentiation of neurons. Third, and possibly most common, is chronic stress. Occasional acute stress is expected and shouldn’t be considered harmful. But chronic stress can damage neurons and make it harder to think even if your neurons are not damaged. High cortisol levels are associated with brain atrophy, which is a clear indication of damage.

Fixing the Leaks

Dr. Bredesen uses a metaphor of the brain as a house with a leaky roof. If you have a lot of places where the roof leaks, you need to fix all of them to stay dry. But your roof may leak in different places from your neighbor’s roof. Finding the weaknesses and addressing them with personalized medicine is key to changing the course of Alzheimer disease, in Dr. Bredesen’s opinion. It may require attention to diet, exercise, sleep (with adequate oxygen saturation), stress management, brain training, detoxification and possibly supplements such as omega-3 fats or vitamin D. You can learn more from his books and his recent publication in Biomedicines (Aug. 6, 2024).

Too many of us are spending our days staring at screens. Little screens on our phones, big screens on the television, medium-size screens on our computers at work. Our modern lifestyles mean that we spend the vast majority of our time indoors–93%, on average. What is the time inside doing to our health? Is there an outdoor prescription to reverse dementia and depression?

What Is Our Indoor Time Doing to Us?

Humans used to spend a lot of time outside and had their circadian rhythms synchronized with sunlight. Living indoors as most of us do can disrupt that natural rhythm. Bright indoor lighting as well as our favorite screens in the evening can make sleep more elusive. Another consequence of focusing on screens rather than on a distant horizon of land, sea or sky is an increased risk of nearsightedness. Beyond that, screen exposure can increase the chance of brain fog, insulin resistance and immune system abnormalities. If you are spending all your time inside, your body may process that as captivity and begin to rebel.

The Outdoor Prescription

Dr. John La Puma pioneered culinary medicine, making the connection between what we eat and the state of our health. His analysis of the research indicates that spending just 17 mindful minutes outside each day can help reverse the damage we suffer from living indoors. He offers seven types of outdoor prescription, starting with morning light.

Greeting the Sun as the Day Begins

Dr. La Puma encourages us all to start our day by stepping outside for at least a few minutes under the open sky. Before coffee, before screens, morning light gets us off to the right start and helps us sleep better at the end of the day. That light exposure, even on an overcast day, helps us with deeper sleep at night. Deep sleep is critical for maintaining the brain with the glymphatic system as well as for bolstering the immune response.

Before checking your email or your social media, perhaps while the coffee is brewing, make it a point to step outside for a few minutes. If that is too difficult, standing in the doorway or just looking outside through a window screen (not glass) may be enough. Bright morning light exposure is helpful in treating major depressive disorder (JAMA Psychiatry, Jan. 2016). Although the study utilized standardized indoor lights, natural light outside is brighter, even on a cloudy day.

New research shows that bright light during the day reduces the risk of dementia among older people (General Psychiatry, June 24, 2026). The benefit was especially clear for those who spent more time in brighter light (at least 5,000 lux) such as one would get on an overcast day. It was even able to mitigate some of the risk associated with APOE4 genes.

What Is Forest Bathing?

Another practice in Dr. La Puma’s outdoor prescription pad is forest bathing. This idea comes from Japan. Spending time outdoors in a forest environment is extremely healing. It can help modulate the immune system, lower blood pressure and counteract stress. Forest bathing does not require a huge investment of time, either. One Japanese study found that spending just two hours a month in a forested environment can lead to lower blood pressure and reduce techno-stress. A review has found forest bathing beneficial against stress and burnout (International Journal of Environmental Research and Public Health, July 28, 2017). https://pubmed.ncbi.nlm.nih.gov/28788101/

No Forest? No Problem

Many people do not have an actual forest handy. Dr. La Puma describes his outdoor prescription for Sarah, who felt stuck inside her city apartment all the time while she cared for her elderly mother. What he prescribed for her was mindful time in the courtyard of her building, starting with very short periods of five to ten minutes. Gradually her heart rate slowed and blood pressure lowered and she began to recover from some of the chronic problems she had been suffering. Forest-bathing doesn’t really require a forest. One tree, or in a pinch, a shrub, can be pressed into service.

Meet Your Friends Outdoors

There are few things better than spending time outdoors. One outdoor prescription that improves on spending time in nature by yourself is spending some of that outside time with friends. Walking, playing tennis, going for a picnic all help your system recalibrate. Human friends are important, but animals such as dogs or horses can also contribute to our well-being (as we contribute to theirs) when we spend time with them in a natural space.

Taking Your Physical Activity Outside

We all have heard how important it is for us to stay active if we want to maintain good cardiometabolic health, diminish our risk of depression and enhance our chances of staying cognitively sharp. There are advantages to outdoor activity that include but go beyond the benefits of exercise. You can accomplish the same amount of exercise with less perceived effort. In addition to light, and possibly horizons, you also get beneficial microbial exposure and a lot of joy.

Gardening as an Outdoor Prescription

A healthful diet begins with healthy organic soil. Gardening is a great way to experience this for yourself. We asked about people who do not have space for a backyard garden and heard about Greg, who learned to garden starting with a single basil plant indoors.

Minimum Effective Dose for the Outdoor Prescription

Dr. La Puma tells us that the minimum dose to get the benefits of being outdoors is just 17 minutes a day. That’s not very much compared to all the time we spend inside.

Are More People Nearsighted?

Myopia, the technical term for nearsightedness, is increasing at a rapid rate. Globally, 23 percent of the world’s population had myopia in 2000. By 2020, that rate had risen to 34 percent. Some experts estimate that it could reach 50 percent by 2050. Rates among children and adolescents are even higher in some places, reaching 70 percent among East Asians and an alarming 86 percent among Singaporean Chinese youth 15 and under (British Journal of Ophthalmology, July 2016).  Why are so many people, including young people, myopic? Are there implications beyond a need for corrective lenses (glasses or contacts)? Can we reverse this trend by limiting screen time or encouraging more time outdoors? Are there treatments that can help children and adolescents improve their vision?

Which Vision Specialist Should You See?

Eyes are complicated, and caring for vision problems has become increasingly specialized and technically sophisticated. As a result, ophthalmologists (eye doctors) now often treat just one part of the eye, such as the retina or the cornea. Some surgeons specialize in removing cataracts. Others, like Dr. Sharon Fekrat, are expert in retinal surgery. There are also pediatric ophthalmologists who treat children. In addition, some people need to consult a neuro-ophthalmologist or someone who specializes in inherited retinal degenerations, uveitis or ocular oncology. How can you determine which type of eye doctor you should see to address your particular problem most effectively?

What Is in a Complete Eye Examination?

Dr. Fekrat will describe the elements of a complete eye examination. Why is each one included? What further steps are needed if trouble is detected? This will give you an idea of how vision problems are assessed and where to turn for treatment.

Managing Dry Eyes

One of the most common complaints is dry eyes. This condition is uncomfortable as well as common, affecting up to half of adults in the US. What are the causes? Are there treatments? People often use eye drops to alleviate the discomfort. Which ones work best?

What can a person do if they have severe dry eye problems and are referred to a dry eye specialist with an appointment months in advance? Is it dangerous to postpone dry eye care?

What to Do About Blepharitis

When the problem is more the eyelid than the eye itself, doctors call it blepharitis. One typical symptom is crust on the lids, which may feel itchy or scratchy. Some people find that applying warm compresses morning and evening is helpful. Others need medication. You may have seen ads for Xdemvy, which is aimed at reducing the population of Demodex mites living in the follicles of the eyelashes. Mites are not the only problem, however. Sometimes bacterial infections are the underlying cause of blepharitis. Rosacea and seborrheic dermatitis that affect skin elsewhere on the face may also show up with the same symptoms.  Topical ivermectin cream has been used off-label on the eyelid margins and may help reduce Demodex mites, but it is not an FDA-approved eye treatment and should only be used under an eye clinician’s direction because it is not intended for instillation into the eye.

How Will the Doctor Diagnose Glaucoma?

Glaucoma is generally understood as a condition in which pressure inside the eye rises and damages the optic nerve. This disease can lead to vision loss. That’s why intraocular pressure measurement should always be part of the eye exam. But this simple diagnostic technique alone may be incomplete. We’ll ask Dr. Fekrat about additional approaches that might pick up normal-pressure glaucoma. How is it treated?

Age-Related Macular Degeneration Deserves Treatment

Another of the vision problems that can cause serious impairment is age-related macular degeneration. In this disorder, the central part of the retina, the macula, loses its ability to focus. Patients may notice that the central part of the vision is blurry, and it may be harder to see under low light conditions. Ophthalmologists now have a range of medications to inject to slow the progression of macular degeneration.
