While the rest of the world runs full speed, we still live in a very primitive body, within which resides a biological clock that influences the activity of every single cell. Blood sugar, hormone levels, metabolic rates, body temperature, sodium/potassium levels, and immune function are just a few of the things directly linked to the body's internal clock. Altering your biological clock can have a drastic impact on your health.

One important factor that helps determine the amount of sleep a person needs nightly is stage of life.

Newborns sleep an average of 16 to 18 hours a day.

Teenagers need at least 8.5 hours while most adults need around 8 hours to function well.

Contrary to the popular belief, the need for sleep does not decline with old age. While the elderly do find that their slumber becomes more fitful, they continue to need about the same amount of sleep that they needed in early adulthood. For this reason, older people tend to nap often during the day.

If you keep you head, hands and feet warm, you can fall asleep under almost any circumstances.

An alternative (albeit very rarely used) to the Warm Milk Therapy is to eat boiled lettuce.
