![]() ![]() Incidentally, if you don’t wake before your alarm, you probably aren’t getting enough sleep-or you aren’t sleeping on a consistent schedule. “Our bodies, in other words, note the time we hope to begin our day and gradually prepare us for consciousness,” writes Jeff Howe at Psychology Today. When the sleepers were told they’d wake up at 9 a.m., their stress hormones didn’t increase-and they woke up groggier. The days when sleepers were told they’d wake up early, their stress hormones increased at 4:30 a.m., as if they were anticipating an early morning. One night, the group was told they’d be woken at 6 a.m., while on other nights the group was told they’d be woken at 9 a.m.īut the researchers lied-they woke the volunteers at 6 a.m anyway. Sleep scientists at Germany’s University of Lubeck asked 15 volunteers to sleep in their lab for three nights. There’s evidence you can will yourself to wake on time, too. It’s so precise that your eyelids open minutes-maybe even seconds-before the alarm goes off. Your body gets a head start so the waking process isn’t cut short. So, to avoid being interrupted, your body does something amazing: It starts increasing PER and stress hormones earlier in the night. It defeats the purpose of gradually waking up. ![]() Gradually, your sleep becomes lighter and lighter.Īnd that’s why you wake up before your alarm. To prepare for the stress of waking, your body releases a cocktail of stress hormones, like cortisol. About an hour before you’re supposed to wake up, PER levels rise (along with your body temperature and blood pressure). If you follow a diligent sleep routine-waking up the same time every day-your body learns to increase your PER levels in time for your alarm. When PER levels are low, your blood pressure drops, heart rate slows, and thinking becomes foggier. The protein level rises and falls each day, peaking in the evening and plummeting at night. Your sleep-wake cycle is regulated by a protein called PER. So if you hit the hay the same time each night and awake the same time each morning, your body locks that behavior in. Your body is most efficient when there’s a routine to follow. That machine happens to love predictability. It turns your body into a finely tuned machine. ![]() It controls your blood pressure, your body temperature, and your sense of time. ![]() It determines when you feel sleepy and when you feel bright-eyed.
