12PM-2PM - Nap time.

5PM to 7PM - Healing period during which it is best if you return to a happy and supportive family.

8PM-10PM - Preparing for sleep and rejuvenation.

Around 10PM - Growth and healing.

12AM to 2AM - Growth hormone is released and the body begins to build and repair tissues. This is the healing part of the night.

3AM - 4AM - Alertness and memory. Core body temperature reaches lowest levels. Most human errors occur during this period of time - Pilots, taxi drivers, and truck drivers.
