I’ve said it before, sleep is the foundation of health. According to Russell Foster, a circadian neuroscientist at Oxford University, the quantity of your time asleep affects the quality of your time awake. Over a third of our life should be spent sleeping. This can feel like a waste of time, but it’s not! Sleep-deprived people cannot function at their highest ability. Sleep deprivation decreases your ability to remember and process information. A good night’s sleep can give us up to a three-fold advantage in complex problem-solving. Also, cutting sleep short by even an hour or two reduces the effectiveness of your immune system by about 25 percent, leading to more illness and disease. And did you know that lack of sleep increases the release of a hunger hormone that causes cravings for carbohydrates and sugars, making it much more difficult to maintain a healthy weight? Don’t neglect this vital part of your fitness.
For the longest time, I thought something was wrong with me because I always felt so tired during the day. Then I started using my Fitbit to track my sleep. I realized that even when I was in bed for eight hours, I wasn’t getting a full eight hours of sleep. When I first started tracking my sleep, I was getting about six hours each night, on average. Now that I’m tracking it regularly, I make a conscious effort to avoid shortchanging myself on sleep too many nights in a row. I don’t always achieve my eight-hour goal, but when I feel exhausted at the end of the week, I can see how much sleep I didn’t get. And I can try to do better the following week.
