During decades of lab experiments and dozens of clinical trials, scientists have searched in vain for drugs to defeat obstructive sleep apnea, the risky and increasingly prevalent condition in which a person’s upper airway repeatedly collapses during sleep, causing them to briefly stop breathing dozens or hundreds of times each night. Now, a new drug combination has reawakened hopes. Sigrid Veasey, MD, a professor of Sleep Medicine, offers insight on the current available treatment options for the condition.
Michael Perlis, PhD, the director of the Behavioral Sleep Medicine program, is featured in a Psychology Today interview and a podcast on preventing chronic insomnia and how to use cognitive behavioral therapy to treat it.
Namni Goel, PhD, a research associate professor in Psychiatry and Sleep and Chronobiology, is featured in an article that delves into the effects of sleep deprivation.
An article about a technique alleged to help people fall asleep faster cites a Penn Medicine study's finding that 25 percent of Americans suffer from acute insomnia each year.
We have increasingly busy lives, and this "busy brain syndrome" can make it hard to switch off when the time comes for bed. James Findley, PhD, clinical director of the Behavioral Sleep Medicine Program, offers advice on how to prepare for sleep.
If you choose to try and shift your internal clock to morning type, whether it be for personal or professional reasons, there are some factors you can adjust. David F. Dinges, PhD, chief of Sleep and Chronobiology, offers healthy sleep advice.
A lack of shut-eye is linked to obesity, hormonal imbalance, heart disease, diabetes, stroke, cancer, Alzheimer’s, stress, low productivity and dangerous driving. The article cites Penn Medicine research that found that moderate sleep restriction of 6 hours of sleep or fewer each night can seriously impair brain function and behavior in healthy adults.
Richard Schwab, MD, a professor of Sleep Medicine and co-medical director of the Penn Sleep Center, shares tips on how to help prevent insomnia, such as the importance of maintaining a regular sleep schedule.
On Monday, PepsiCo CEO Indra Nooyi announced that she was going to step down as the company's leader. Nooyi is surprisingly similar to her fellow CEOs on the S&P 500 in one critical way: she runs on just four hours of sleep per night. David F. Dinges, PhD, Chief of Sleep and Chronobiology, shares how restricted sleep affects the human body and performance.
A study in mice found that sleep cleanses the brain of toxins that accumulate during waking hours, some of which are linked to neurodegenerative diseases. During sleep, the space between brain cells increases, allowing toxic proteins to be flushed out. Sigrid C. Veasey, MD, a professor of Sleep Medicine, shares insight on the role of sleep in aging.
Some exhausted adults are turning to sleep coaches in search of solutions that don't involve prescription sleep aids. The article cites a Penn study finding that about one in four Americans experiences acute insomnia each year.
A significant body of research speaks to the harmful effects of noise: from the more obvious hearing loss to stress, sleep deprivation and increased cardiovascular risk linked to noise exposure – like from that living near an airport. Mathias Basner, MD, PhD, an associate professor of Sleep and Chronobiology, is quoted.
A new Penn Medicine study from Namni Goel, MD, a research associate professor of Sleep in Psychiatry, and colleagues has found a way to help predict vulnerability to the negative effects of sleep loss.
There’s a scientific reason your body sleeps poorly in a hot bedroom. It’s a smaller temperature gradient—or the difference between your core body temperature and the room temperature—that triggers a sleepless night. The optimal gradient is the difference between your core body temperature, 98.6 degrees Fahrenheit, and about 68 degrees, the temperature sleep experts say provides an optimal sleep environment. Philip Gehrman, PhD, an associate professor of sleep medicine in Psychiatry, offers tips on the best ways to beat the heat and catch some Zzs.
If you are not getting at least seven hours of sleep each night, you might be dealing with signs of high-functioning sleep deprivation. Bustle cites insights from David F. Dinges, PhD, chief of Sleep and Chronobiology, on how sleep deprivation can impair our ability to detect emotions.
