The Power of Sleep

By Noelle noelle bio picture

Enough sleep is just as important for good health as nutrition and exercise.

Did you know?

Too little sleep upsets the balance of hormones that control appetite, energy, metabolism, and glucose processing. This lack of sleep causes the body to:

  • Increase the amounts of the steroid hormone cortisol in the body. Cortisol is known as the “stress hormone.”
  • Increase in insulin following a meal. Insulin is a hormone that regulates the glucose processing and promotes fat storage…higher levels of insulin are associated with weight gain.
  • Lower levels of leptin. Leptin is a hormone that tells the brain that the body has had enough food.
  • Increase ghrelin levels. Ghrelin is a biochemical that stimulates appetite. When ghrelin increases in the body t sends signals to the brain telling it that you’re hungry.
  • Perform at lower level mentally.
  • Struggle to remain healthy.

Losing just a few hours of sleep a few nights in a row can lead to almost immediate weight gain.
