Why is a good sleep important?

Dr. Michael Roizen, MD
Internal Medicine
Your body needs time to rest and regenerate, and getting enough ZZZZs will give you more energy and make your waking hours more productive and enjoyable. Sleeping just two hours less than normal impairs your judgment and reaction time to the same extent as a blood alcohol level of 0.12. This level is 50 percent higher than the level at which most states say drivers are inebriated. And you need your sleep to prevent aging of your immune system. So, enjoy a full night's sleep every night. It can make your RealAge (physiologic age) at least three years younger.
