While you sleep, extraordinary things go on in your body to renew you:

Nature Recharges You
During dream sleep, the biological processes that maintain your warm body temperature temporarily shut down, giving nature a chance to re-stoke your furnaces. During this re-charge, you miraculously move from being ‘warm-blooded’ to being ‘cold-blooded’.

Nature Rehydrates You
During well supported sleep, your spinal muscles will relax completely for a deep sleep. Your body then rehydrates and decompresses the spinal discs, leaving them revitalised.

During sleep, the average person will go through 8 – 12 major postural changes each night and will move at least 70 times (emphasising the need for healthy posture support during sleep).

Nature Chemically Regulates You
Significant surges in hormones take place to regulate our metabolism and other bodily functions like growth and enzyme production. For example your brain produces Serotonin and Melatonin while you sleep. Serotonin is known as the happy enzyme. It modulates mood, emotion, sleep and appetite. A lack of Serotonin may result in depression. Melatonin resets the body clock to synchronize metabolic functions with times of activity and rest.

Nature Normalizes Your Blood Pressure
A fall in blood pressure and heart rate during quiet sleep and dramatic swings in these rates during dream sleep are thought to be important in keeping daytime blood pressure normal. Hence some people who have difficulty sleeping will suffer high blood pressure.
