Be honest: are you getting enough sleep?
No, me neither.
It's not exactly surprising, since experts say that one in three people are sleep deprived.
In fact, sleep science says that even eight hours of rest isn't enough. Most adults between 25 and 65 should be aiming for nine hours.
That's a lot to ask of us in this busy world of ours, but there's a good reason to get some shut-eye.
If your body is sleep deprived, you can expect these 13 serious side effects:
1. Your heart suffers
Without those effects, your risk of developing heart disease rises sharply.
That puts you at risk of other conditions, including deadly ones like a heart attack or stroke.
2. Your memory fails you
Your brain build memories by connecting related thoughts in two different parts of your mind using brainwaves.
This process mostly happens while you're asleep. So cutting back on rest makes it harder to remember anything.
Studies on mice also show that sleep helps remove toxic chemicals that damage your brain.
Over time, if this damage isn't kept in check, it could lead to dementia or Alzheimer's.
3. Your decision-making skills weaken
Like memories, the "cognitive procession" that helps you make important decisions relies on sleep.
The more tired you are, the longer and more difficult it is to make decisions.
Why does that matter? When you're sleep deprived, you tend to make bad decision about what you eat, how you spend your time, and even how much sleep you get.
It's a vicious cycle.
4. Your vision gets worse
Your eyes rely on muscles, just like the rest of your body, including a critical one that moves your eyes up, down, and side-to-side.
When you're really tired, you'll start to notice double vision and trouble reading things.
Sleep is called shut-eye for a reason. If you don't rest your eye muscles for long enough, you could permanently harm your vision.
