Earn up to one point daily this week (Days 1-7) by sleeping at least 8 hours. This should be a consecutive nights rest and naps do not count towards this 8 hours. Keep in mind, in order to get a full 8 hours of actual sleep you may actually need up to 8 1/2 to 9 hours of “time in bed” to make sure you’re getting an adequate amount of sleep time.
An adequate amount of rest is key to a healthy lifestyle by building our immune system, raising mental acuity, and helping in exercise recovery, among many others benefits.
