One night of lousy zzzs, just one night, is all it takes for your stress level to go through the roof, scientists are discovering. “The quality of your shut-eye plays a crucial role in the way you cope with stress,” says Jennifer Martin, a clinical psychologist and behavioral sleep medicine specialist at University of California, Los Angeles. “Lack of sleep affects the brain’s ability to regulate your emotional response to events,” she says. More specifically, after that single bout of tossing and turning, the areas of the brain involved in processing emotions become so hypersensitive that your reaction to something stressful may rocket out of proportion, and cause you to freak out for no reason, accord ding to studies from University of California, Berkeley.

It doesn’t end there as the extra stress makes sleep even more elusive the following night. “Your cortisol levels are elevated and your heart is pumping faster – two things that keep you awake and impair the quality of your rest once you do drift off,” Jennifer says.

In fact, research shows that people who slept just four hours one night had higher levels of cortisol the next night, making it hard for them to get back on track. It’s a classic catch-22: you need sleep to de-stress but are too frazzled to turn in, and the lack of rest makes you even more tense. Break free of the draining cycle with the latest research and expert advice.

WORK OUT AT NIGHT – IT’S FINE

Traditionally, it was believed that exercising too close to bedtime would hype you up, making it harder to nod off. That’s not necessarily true, says Kelly Baron, a sleep expert and an assistant professor in behavioural sciences at Rush University Medical Center in Chicago.
