Experts emphasize the importance of recognizing when repeated yawning and nodding off could be symptoms of an underlying sleep deficit. “The unfortunate thing is data shows that with chronic partial sleep deprivation the ability to perceive our own level of impairment is no longer accurate," said Indira Gurubhagavatula, MD, MPH, a professor of Sleep Medicine. "We think we’re OK when we’re really not." Tags: earth.com sleep_medicine indira_gurubhagavatula microsleeps EH FY25 2025 Q4 June

Ilene M. Rosen, MD, an associate professor of Sleep Medicine, will be recognized with the Excellence in Education Award from the American Academy of Sleep Medicine (AASM) on June 9, during the plenary session of the SLEEP 2025 annual meeting of the Associated Professional Sleep Societies in Seattle. Rosen's research focuses on innovative sleep medicine education and expanding access to care. Tags: Sleep_Review ilene_rosen sleep_medicine american_academy_of_sleep_medicine EH FY25 2025 Q4 May

Sleep apnea, where breathing is interrupted for seconds or minutes at a time during sleep, affects people of all ages, genders and body types, according to Indira Gurubhagavatula, MD, MPH, a professor of Sleep Medicine. “The most common symptom of sleep apnea is loud, persistent snoring,” Gurubhagavatula noted. However, because of the unconscious nature of sleep, it can be tricky to determine whether you snore, much less experience sleep apnea episodes, unless a family member, roommate or partner notices.

The answer is: maybe, since most adults need at least seven hours a night. To feel well rested and function your best during the day, it can be helpful to identify your sleep need and establish a schedule that aligns with it. A review by Michael Perlis, PhD, an associate professor of Psychiatry, identified sleep need as the minimum amount of sleep we require in a 24-hour period to function well. Failure to meet this need can result in sleep deprivation, which affects a wide range of physical and mental functions.

From sleep issues to Alzheimer’s to antibiotic resistance, three Penn researchers are taking aim at some of the more daunting aspects of aging. Joseph Baur, PhD, a professor of Physiology; César de la Fuente, PhD, a Presidential Associate Professor of Psychiatry, Microbiology, Bioengineering, Chemical and Biomolecular Engineering, and Chemistry; and Michael Perlis, PhD, an associate professor of Psychiatry, share insights into how their work can help us live longer, healthier lives.

Some research suggests drinking ashwagandha tea may positively impact sleep, but many others won’t help at all. Richard Schwab, MD, chief of Sleep Medicine, cautioned against sugary drinks or alcoholic cocktails. "Alcohol causes sleep fragmentation and is definitely not good for sleep. It may help you to fall asleep, but then it will fragment your sleep and prevent you from reaching deeper stages of sleep, which is bad," Schwab said.

While drinking alcohol may help us fall asleep, it is among the main reasons why we have trouble staying asleep. Richard Schwab, MD, chief of Sleep Medicine, said that alcohol disturbs sleep by raising body temperature. "This causes the heart to beat faster, which is likely the reason why it can interrupt sleep," he said. Tags: Parade richard_schwab sleep_medicine alcohol EH FY25 2025 Q4 April

Socks can keep toes toasty and create a sense of comfort—while also lowering core body temperature, promoting sleep. “When we warm up our feet by wearing socks, the blood vessels under the skin dilate not just in the feet but everywhere,” said Indira Gurubhagavatula, MD, MPH, a professor of Sleep Medicine. “This allows warm blood to come to the surface, and as it keeps circulating and coming to the skin, body heat is shed, and core body temperature eventually drops.” Tags: Washington_Post top_tier sleep_medicine indira_gurubhagavatula EH FY25 2025 Q4 april

The American Academy of Sleep Medicine warned of the "clinical significance" that excessive sleepiness has on performance, health, mood, safety and quality of life in a new position statement. When the body is continuously sleepy, it may send false signals to the brain, forcing mini naps known as microsleeps. Indira Gurubhagavatula, MD, MPH, a professor of Sleep Medicine, cautioned against activities like driving in these instances.

Signs of sleepiness like yawning may be a red flag of a serious sleep deficit that could put you in physical danger and harm your long-term health, according to a new position paper by the American Academy of Sleep Medicine. Indira Gurubhagavatula, MD, MPH, a professor of Sleep Medicine, said that, with continued sleepiness, the brain may take mini naps, or what specialists call microsleeps. “Your brain is actually going into brief two-second, three-second, 10-second microsleeps and then popping back out and you may not even realize this is happening,” she said. “It can be very dangerous if you’re driving or doing something that involves safety."

Cognitive shuffling typically involves conjuring up random, impersonal and non-emotionally charged words. For each letter of a word you pick at random, you think of as many corresponding words as you can for a few seconds each before moving to the next letter. Since our brains tend to “shuffle” between random thoughts during quieter periods, giving our brains a calming or neutral distraction can be more helpful than allowing them to find something on their own," said Kami McManus, PsyD, a sleep psychologist in Sleep Medicine.

As many as 30 million Americans have sleep apnea—a disorder where breathing is interrupted during sleep. Grace Pien, MD, MSCE, associate professor of Sleep Medicine, shared that snoring, snorting, and coughing during sleep are important hallmarks of sleep apnea. In addition, waking up with a dry mouth, daytime drowsiness despite devoting enough hours to sleep, morning headaches, difficulty focusing, or feeling more anxious, depressed, or irritated are indicators.

Many people turn to white noise machines to help them sleep, but a research review found that the devices may not be so helpful. Mathias Basner, MD, PhD, professor of Sleep and Chronobiology in Psychiatry urged caution with using white noise machines or apps because “there may be negative consequences. I wouldn’t broadly recommend them, because there is no evidence that they are actually working."

What happens to your body when you deliver a 25-hour speech without any breaks, as Sen. Cory Booker did recently? Speaking for that long demands a lot of cognitive energy, said Indira Gurubhagavatula, MD, MPH, a professor of Sleep Medicine. People who pull all-nighters can struggle to pay attention. Even just one night of poor sleep, or no sleep, can impair short-term memory, or make it hard for people to concentrate enough to be articulate.

A growing number of adults are snuggling up with their favorite stuffed toys at night, often as a way to sleep better. “Kids love stuffed animals. It’s because they’re cozy and… just personified enough to provide a bit of social comfort. That’s a great way for kids to self-soothe. We adults can do the same thing," said Jennifer R. Goldschmied, PhD, an assistant professor of Psychiatry. Tags: first_post jennifer_goldschmied psychiatry sleep_medicine EH FY25 2025 Q4 April
