Understanding sleep, the power of it and how to get as much high-quality sleep as possible is one of the healthiest things we can do.

• Sleep is a naturally recurring state characterized by reduced or absent consciousness, and the inactivity of nearly all voluntary muscles.
• Sleep timing is controlled by the circadian clock, and in humans, to some extent by willed behavior.
• Sleep is restorative, and without it we are not able to work, learn, create and communicate at our highest level. With time, lack of sleep can lead to mental and physical breakdown.
• Sleep has also been shown to be linked to the immune system. Sleep loss can impair our immune function.
• When we sleep, our metabolic rates reduce and free radical production is decreased, allowing restorative processes to take over.
• Sleep supports higher-level cognition functions such as decision- making, reasoning and memory.
