How a Single Patient Sparked a Sleep Research Program
Buchi Neita, PA-C, and Shanna Miranti, PA-C open by revisiting Dr. Tina Bhutani's popular "Wake Up Dermatology" lecture from the Elevate Summer Conference in Park City (July 2025), then dig into why sleep has taken center stage in health conversations. Bhutani points to the last five years of wearables and sleep-tracking apps, and to a broader cultural shift: where sleep used to be dismissed ("I can sleep when I'm dead"), sleep-medicine research over the past 10 to 15 years has established just how many critical functions happen while we rest.
Her interest began with a patient who had recalcitrant psoriasis that never fully cleared—until one day it did. The difference wasn't a new medication. His wife had been diagnosed with sleep apnea and moved to a separate room with her CPAP machine, and only then did he realize he had been woken up repeatedly every night for a decade. Once he actually got uninterrupted sleep, his psoriasis began to clear. Bhutani calls that an "n of one," but it pushed her into the literature, where she found strong ties between sleep, the immune system, and the same comorbidities dermatologists already track in psoriasis — cardiovascular disease, diabetes, obesity, and certain cancers.
That work grew into UCSF's "dreams team," which Bhutani built alongside fellow dermatologist Dr. Wilson Liao and sleep researchers including Drs. Aric Prather, Andy Krystal, and Katie Stone. The group recently finished its first study, putting both psoriasis patients and healthy patients in a sleep lab to compare sleep patterns and blood biomarkers, with the first publication expected soon.
Sleep and Inflammatory Skin Disease Are a Two-Way Street
It seems obvious that itchy, uncomfortable atopic dermatitis and psoriasis keep patients awake, especially since symptoms often intensify at night. But Bhutani stresses the relationship runs deeper. Even when you control for subjective symptoms, these patients' sleep still isn't good — which points to something beyond scratching.
Drawing on research from rheumatology and gastroenterology, she explains that an overactive immune response appears to fragment sleep. Track inflammatory markers alongside sleep, and the pattern emerges: inflammation seems to drive poor sleep. Because psoriasis and atopic dermatitis are systemic inflammatory diseases, clearing the skin doesn’t necessarily switch off the underlying inflammation that may still disrupt rest. As Bhutani frames it, these conditions demand a comprehensive approach, not just skin-directed treatment.
What to Ask — and the One Statistic That Should Get Your Attention
Bhutani is candid that clinicians can't yet look at someone's skin and diagnose a sleep problem. Instead, she reframes the screening question. Asking how many hours patients sleep is elusive — people report eight hours while actually tossing, turning, and waking repeatedly. After much practice, she now asks whether patients feel well rested when they wake up. If they aren't rested despite adequate time in bed, that disconnect signals it's time to dig deeper.
Miranti flags a statistic from the lecture that stuck with her: for each additional hour of average nightly sleep, psoriasis patients had 33% lower odds of having a heart attack. Bhutani explains the compounding math — psoriasis raises cardiovascular risk, sleep disturbance independently raises it, and together they multiply the odds of bad outcomes. That makes even a brief sleep conversation potentially high-value.
She also acknowledges the real-world pressure of adding one more thing to a packed visit. Her advice: don't try to do it all at once. These are chronic diseases seen repeatedly, so tackle one item per visit — blood pressure today, confirming a primary care doctor and cholesterol checks next time, then sleep or mental health after that.
What Sleep Does for the Body — and What Happens Without It
Bhutani describes sleep as when the immune system resets and refines itself. Much of immune memory formation happens overnight — antigen-presenting cells and memory T cells are most active in the middle of the night. She likens the brain's overnight clearing of oxidative byproducts to "running the dishwasher at night," and suspects a similar clearing of messy immune byproducts helps the immune system function optimally by morning.
The short-term costs of poor sleep are familiar: emotional and stress reactivity (Miranti compares it to a toddler or a new mom), plus poorer decision-making — even two nights of bad sleep make people more likely to choose the burger and fries over the salad. Chronically, poor sleep produces the comorbidities that overlap with psoriasis: cardiovascular disease, obesity, and diabetes.
Crucially, Bhutani notes that chronic sleep disturbance is itself a pro-inflammatory state — inflammatory markers are elevated even in people without disease. Layer an inflammatory skin condition on top and the inflammation compounds. She suggests "inflammation" resonates with patients and can help clinicians explain why sleep matters. She also cites that over a third of U.S. adults aren't getting the recommended seven-plus hours, with disparities across races and income levels.
Practical Sleep Hygiene You Can Hand a Patient
Bhutani keeps a sleep hygiene handout, and notes clinicians can find similar lists by searching "sleep hygiene techniques." Her quick, clinic-friendly recommendations: shut down screens about an hour before bed to avoid blue-light stimulation; keep the bedroom cool and wear lightweight cotton clothing; keep the bed comfortable and reserved for sleep; cut caffeine later in the afternoon; and keep naps short so patients are actually tired at night. One colleague's memorable rule: the only two things you should do in bed are sleep and sex — anything else, leave the room and come back.
When patients still don't feel rested despite good hygiene, Bhutani refers them back to primary care to evaluate for diagnosable conditions like sleep apnea or restless legs syndrome. And if there's time for only one message, she says it's this: make sleep a priority rather than something that happens after everything else. The hosts close by extending that to caregivers, teenagers, and the next generation — building good habits early.
