Sleeping with Even a Little Light Can Be Unhealthy

Sleeping with Even a Little Light Can Be Unhealthy

Just a night or two of exposure to faint light is enough to raise your pulse and increase insulin resistance - factors that increase the risk of heart disease and diabetes, researchers find.

The findings tie into a broader body of evidence that indicates being exposed to light at night may be harmful in a variety of ways and could predispose people to chronic diseases.

Physiological Effects of Light On Sleep

  • An extensive study showed that unlike those who spent nights in the dark, the test group exposed to the light had elevated heart rates throughout the night.
  • They also had increased insulin resistance in the morning, meaning they had more trouble getting their blood sugar into a normal range.
  • Artificial light at night can suppress melatonin levels, and scientists have found a link between the disruption of melatonin and several diseases, including cancer and diabetes.

Increased Risk of Chronic Illness

The body's "master clock," called the suprachiasmatic nucleus, is found in the brain, but organs and tissues throughout the body have their own cellular timekeeping devices. Cells in the pancreas that secrete insulin are one example. Disrupting the sleep-wake cycle can affect their ability to appropriately secrete insulin, which in turn controls blood sugar.

If this pattern continues for a long period, it increases the risk of various chronic diseases.

This app is LOADED with RELEVANT, HELPFUL, AND EDUCATIONAL material. It is creatively intellectual, yet minimal enough to not overstimulate and create a learning block. I am exceptionally impressed with this app!

I have only been using it for a few days now, but I have found answers to questions I had never consciously formulated, or to problems I face everyday at work or at home. I wish I had found this earlier, highly recommended!
