Remember those days when you slept well, and you were happier? When you also felt healthier and used to get more done each day without feeling overburnt?

Somewhere down the line, you must have lost the ability to get a good night's sleep. And that's so bad because sleep is the way nature repairs your body. Without sleep, you'll be running on fumes soon enough.

You've heard it before. You need to get more sleep. But maybe you need to understand what goes on in your body while your sleep debt goes up? That way, you might feel more inclined to sleep on it and give it a go.

Here's what's happening under the hood when you don't get 7 to 8 hours of sleep a night regularly.

1. You're not pleasant company, and you know it

When you're tired, you're cranky. You're less compassionate about other people's needs.

Your brain is so slow that you might even not get a good joke (yeah, can you imagine that?) You might pick up fights for the stupidest reasons. Or get into a fight in entirely avoidable circumstances.

Being tired brings out the worst of you. And your family and friends would deserve the best of you, don't you think so?

2. You're irresistibly attracted to certain foods

Not broccoli or asparagus, but rather pizza, hamburgers, mac and cheese, fries, and other fatty or sugary foods.

You want an energy boost. You need fats to stay alive, so your body is telling you to get it when you're running low on energy too.

Just like you shouldn't go shopping on an empty stomach, you shouldn't be opening the fridge when you risk falling asleep in front of it.

3. You're risking accidents and injuries

Are you thinking of that time when you were so sleepy that you spilled the hot coffee on yourself?

I'm thinking more of that time when you nearly crashed into another car. The risk of being involved in accidents is significantly higher when you're sleep-deprived…
