Drug combo shows promise for treating sleep apnea


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.

This Is Why You Can't Fall Asleep in the Summer


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.
