Want to be a healthier, happier and more productive person all day long? Then consider hitting the hay at the way-early time of 8:45 p.m., which The Cut just declared "the best time to go to bed." "Nothing good happens after you’ve been up for 16 hours," the site adds. "At first it might feel like you’re missing things, but eventually you will be so well rested, and so well adjusted, that you’ll float above such petty concerns." An 8:45 bedtime means you'll probably be asleep by 9:15, allowing you a restful eight hours of sleep before rising 5:15 a.m.
