Sleep to a Better Beat
A good night's sleep is essential for a healthy ticker. Lack of sleep can lead to hypertension.

Getting by with Less
Some people can survive on very little sleep, while others require many hours to function normally. If you still perform relatively well when sleep deprived, the reason could be your genes.
