Great reasons to sleep naked.

1. The cooler, the better sleep. Wearing pajamas and a thick blanket can be harmful to your sleep. Your body temperature needs to drop so that you can sleep in optimal conditions, which means that blankets and clothing can disrupt your sleep. This is not entirely good, given that the lack of coolness is unhealthy and means a very unpleasant morning. 2. Younger every morning. Well, not exactly, but the aging process will be much slower. While we sleep, we secrete growth hormone (a natural anti-aging substance), and when sleep is disturbed by high temperatures, we produce less of it and age faster.
