The worst thing people can say about your appearance is that you look tired. Not getting enough beauty sleep may be the downfall of you. Here are some reasons why being sleep deprived is not something you want on your to-be list.

1. Your brain just doesn't work well

You experience poor motor skills, emotional problems, poor judgement, impaired learning ability and more.

2. You won't really know how sleepy and impaired you are

You just won't be able to tell how tired and impaired you really are.

3. You will eat a lot because your appetite goes up

Leptin and grehlin help regulate your appetite and feelings of fullness, but if you're sleep deprived the correct ratio of those hormones gets impaired.

4. And you end up eating high-calorie foods

Somehow, that cupcake and chocolate bar looks helluva delicious.

5. Your metabolism gets screwed

Your body won't be able to metabolize food as efficiently as it usually can.

6. Losing sleep could cause you to gain weight

7. General health gets affected

From hypertension to diabetes and obesity and depression there's also heart attack and stroke.

8. If you have sleep apnea, you are at a higher risk of cardiovascular disease

Sleep apnea is a condition where people stop breathing for periods of time while they sleep and is a very serious medical condition. It can go undiagnosed and untreated.

9. Electronics and screens suppress the release of melatonin

Which is the stuff your body needs to repair itself.

10. Interrupted sleep isn't good sleep at all

Your pets and gadgets are causing you more harm in the bedroom.

11. An erratic sleep schedule isn't a good schedule

Sleeping at 10pm and getting up at 6am on weekdays but sleeping at 6am on weekends seriously screws up your sleep cycles.
