We All Have A Personal Wind Down Time—Here’s Why It Matters

Rountree says that the human mind takes a while to relax. "At least an hour – probably two," he said mbg co-founder Jason Wachob recently at a virtual sleep summit. "It takes me two hours to relax. Two hours to do things that are quiet after dinner, like talking or reading."

To find out how long it will take to relax, give yourself at least an hour and a half to begin. For example, if you want to fall asleep around 10 p.m., start doing relaxing around 8:30 p.m. When it's time to go to bed, report to yourself. Are you still a little energetic? Or maybe you were ready to go to bed at 9:30 a.m., which indicates that it only takes you an hour to relax.
