People realize that sleep is important but they actually don’t realize how “incredibly” important it is.
Not getting enough sleep is the single best way to destroy your health.

Let’s look at why it’s so important for you to sleep better.

1. Lack of sleep Makes You Fat

Sleep deprivation makes you hungrier because it reduces the levels of leptin (the chemical that makes you feel full) and increases the levels of ghrelin (the hunger-stimulating hormone). 

2. Falling Short On Sleep Increases Belly Fat

When you don’t get enough sleep, your body releases more of the stress hormone “cortisol”. Cortisol is a fat generating hormone. 

3. Sleeping Less Hinders Your Muscle Growth

Sleep deprivation reduces the amount of recovery time provided for muscle repair and muscle growth. 

4. Poor Quality Sleep Can Negatively Impact Human Growth Hormone Levels (HGH).

Human growth hormone (HGH) is released under conditions of sleep.

In men, 60% to 70% of daily human growth hormone secretion occurs during early sleep which is typically when the deepest sleep cycles occur (what we call slow-wave sleep).

When we’re young, human growth hormone promotes growth. As we age, it helps increase muscle mass, thicken skin, and strengthen bones.  

5. Lack of Sleep Decreases Your Sex Drive

Depleted energy, sleepiness, increased stress and decreased testosterone levels are the major factors in the sexual slump.

6. Not Getting Enough Sleep Decreases Your Fertility

Difficulty conceiving a baby has been claimed as one of the effects of sleep deprivation in both men and women. It can impair fertility by reducing the secretion of reproductive hormones.

7. Lack of Sleep Ages Your Skin

Most people have experienced sallow skin and puffy eyes after a few nights of missed sleep. Constant sleep loss can lead to lackluster skin, fine lines, and dark circles under the eyes.  

8. Sleepiness Is Depressing

Sleep loss often aggravates the symptoms of depression and depression can make it more difficult to fall asleep. On the positive side, treating sleep problems can help depression and its symptoms, and vice versa.

9. Not Getting Enough Sleep Decreases Your Brain's Processing Speed 

Sleep plays a critical role in thinking and learning. Lack of sleep weakens attention, alertness, concentration, reasoning, and problem solving.
