You wake up at 3 a.m. No reason. Everything is quiet. And yet - awake. If this happens to you regularly, you're not alone and, more importantly, your body isn't broken. Sleep specialists say this is one of the most commonly misunderstood phenomena in the field of sleep.

The specialists at The Sleep Project, Dr. Kaitlyn Chase and Polly Revaliente, explain: the body cycles through 90-minute sleep stages. In the second half of the night, sleep naturally becomes lighter, and cortisol - the wakefulness hormone - starts rising. Brief moments of waking up are part of the biological program, not a sign something is wrong. In the first half of the night you simply don't notice them - in the second, you notice them and activate the brain.

The problem isn't the waking - it's the panic after the waking. "Sleep and wakefulness can't happen at the same time," the specialists say. When you wake up and start counting how many hours of sleep you have left, you trigger the alarm system in the brain - and it can no longer go back to sleep. The body is awake because you're telling it it has to be awake.

Strategies that actually help: slow breathing or guided relaxation, absolutely no checking the phone or clock, and if sleep doesn't come back within twenty minutes or so - get up, do something quiet under minimal light, and come back. For chronic insomnia, cognitive behavioral therapy is the first choice, not pills. The body knows how to sleep - you just have to let it.
