9. Aging Skin and Hair Loss
From dark circles to hair thinning, sleep can impact your physical appearance.
With lowered levels of sleep, your body is triggered to release more cortisol (the stress hormone).
This release of the stress hormone breaks down the collagen in your skin—the protein that gives skin its elasticity.
The loss in elasticity leads to premature wrinkles.
If your stress levels are higher from lost sleep, you may see increased hair shedding in 6-12 weeks.
During sleep is also when the growth hormone is released, a key part of tissue repair in the skin and increased growth for the hair.
Sleep deprivation can lead to heart attacks or strokes.
Your heart has to work in overdrive when you don’t give it time to fully rest at night.
Your heartbeat slows to a resting rate as soon as you start to enter the first stage of non-REM sleep, reaching the lowest levels during stage 3 sleep.
During REM sleep, your heart rate will increase, but still not quite to waking levels.
Without the ability to drop to a healthy resting heart rate, the risk of near mortality is much higher.
11. Daytime Fatigue and Nausea
Have you ever woken up after not enough time and feel sick to your stomach?
You can be perfectly healthy and still feel nauseous if your body wasn’t in the right sleep stage.
You might also experience headaches, lightheadedness, dizziness tremors and body aches. Some call it the “insomnia hangover.”
