According to Sleep Expert and Neuroscientist Dr. Matthew Walker, “Sleep is the greatest legal performance enhancing drug that most people are probably neglecting” and you need 7-9 hours per night, once you start falling below 7 there are significant measurable impairments in brain function. If you get below 6 hours, you reach physical exhaustion 30% faster. Various environmental factors can have a massive impact on sleep, diet, drug and alcohol use, screens, stress, and many other things.
As they say in business, what gets measured gets managed. That’s why investing in a sleep tracking device is probably the best thing you can do for your health, to help you nail down good habits and fine tune your sleep hygiene.
