The brain and the nervous system are the most important organs we have. They control the function of every cell, tissue and organ in the body.
Even when we are sleeping, the brain is functioning. Sleep enhances performance, learning and memory.
If you are having trouble finding a solution to a problem, try sleeping on it, you may find the answer. This is because sleep helps you to reset your brain and see things from a different perspective.
Dr. Mercola says too little sleep can:
1. Alter your metabolism and make you gain weight.
2. Cause your brain to stop producing new cells.
3. Increase your risk of cancer by altering the balance of hormones in your body.
4. Increase your risk of diabetes by reducing your leptin levels.
5. Accelerate aging.
6. Increase your risk of heart disease and stroke.
7. Raise your blood pressure.
8. Speed up tumor growth. Tumors grow two to three times faster in laboratory animals with severe sleep dysfunctions.
Dr. Mercola goes on to say that your body does most of its repairs during sleep, so not getting enough of it can impair your immune system, leaving you less able to fight off diseases of all kinds.
Adults need on average 6-8 hours of quality sleep per night. Sleeping more than 8 hours can have the same effect on you as not sleeping enough. There are times that require extra sleep such as an illness, emotional stress and/or pregnancy just to name a few.
