Sleep is a restorative activity, and if sleep time is cut short or fractured (interrupted) the body does not have time to complete repairs or restore energy. Hormones are not released in the proper amounts.
Epidemiological studies have shown that people who sleep less than 6 hours may show the following:
- Increased risk of developing hypertension, stroke, obesity, and diabetes
- Acceleration of memory loss
- Reduction of immune system function
- Increase of osteoporosis (animal model), cardiac disease, and mortality
- Increased risk for colon cancer and likelihood of precancerous polyps
Regular sleep affects daily functioning and physical, mental, and emotional health. It is essential for our survival.
