Lack of sleep affects every physiologic function of the body. You already know that lack of sleep can make you irritable throughout the day. What you may not know is what it can do to your memory, health, physical appearance and even your ability to lose weight. Here are 5 dangers of not sleeping enough:

1. Sleep Loss makes you Dumb

Lack of sleep may affect the brain development by decreasing cognitive processes like thinking and learning. This makes it more difficult to learn or think efficiently, technically making you dumber.

2. Sleep Loss causes Depression

Insomnia has been linked to depression. Sleep loss contributes to cause depression. It may make you lethargic, irritable and stressful throughout your day.

3. Sleep Loss ages your skin

Losing sleep causes lackluster skin, fine lines and dark circles under the eyes. When you don’t get enough sleep, the body releases more of the stress hormone cortisol which may breakdown the skin collagen that keeps the skin smooth and elastic. Sleep loss also causes the body to release less human growth hormone.

4. Sleep Deprivation can lead to serious Health problem

The clinical consequences of untreated sleep disorders may lead you to numerous serious medical illnesses for e.g. heart attack, high blood pressure, obesity, etc.

5. Sleep Lose can make you gain weight

Lack of sleep seems to be related to an increase in hunger and appetite, and possibly to obesity. Losing sleep decreases Leptin levels and elevates Ghrelin levels, which stimulates hunger. It not only stimulates your appetite but also stimulates cravings for high-fat, high-carbohydrate foods.

You should hit the snap for at least 7-8 hours every night.
