Getting a good night’s sleep is an effortless technique to create longevity and health. Deep rest during the night helps you fight stress, maintain a healthy weight, and keeps your energy levels high.

The deepest and most regenerative sleep occurs between 10 p.m. – 2 a.m. After 2 am, your sleep becomes more superficial.

You have an internal clock lodged deep within the brain that regulates your sleep – the pineal gland. The pineal gland receives information about the sun through your eyes via the optic nerve. As the sun sets, the pineal gland is able to sense the change in light transmitted through your eyes and it begins to secrete a hormone, melatonin, to prepare your body for sleep.

Exposure to bright light prevents the secretion of melatonin and darkness promotes it.

At 10 p.m., your body goes through a transformation following the rise in melatonin production. This transformational phase of sleep is associated with an increase in the “internal” metabolic activity that is responsible for the repair and restoration of your body.

If you are awake past 10 p.m., this process of free radical removal becomes interrupted, and your body’s ability to remove the effects of free radicals is significantly impaired. Most people who stay awake past 10 p.m. are usually working on the computer, watching TV or reading. All of these activities result in exposure to light and therefore interrupt the production of melatonin. Secondly, the metabolic energy that becomes available at 10 p.m. for the removal of free radicals is expended and now unavailable.

So you are interfering with your bodies repair system, this is very dangerous for your health.
