You are not a bad person if you don’t sleep eight hours a night. I once taught myself to wake up at 5 AM every morning and I did it for two years because I thought it would make me healthier and stronger and more productive. It just made me tired and less creative. The advice that we’ve received all of our lives about eight hours a night is crumbling in the face of scientific data. You may need more sleep or less sleep, and you may need to go to bed earlier or later. What’s missing from the conversation is sleep quality. What if seven hours of great sleep was better than nine hours of bad sleep? That is something that you can control. After 14 years of tracking my sleep almost every single night, being CTO of one of the wristband tracking companies, and writing some of the most influential sleep hacking blog posts on the Internet, I am now hosting a special 14 days sleep challenge that starts tonight. Do you want to know everything that works? Distilled for you, easy to learn, easy to do? Join thousands of people doing the new #Aspreysleepchallenge right now. Just DM (private message) me the word SLEEP so you can get started! See you in bed! 🤪 #sleep #night #bedtime #goodmorning #sleephacking #biohacking」8月18日 0時35分
