You Probably Had No Idea Your Body Could Do These Bizarre Things

Your body has some incredible super powers. It can heal itself from illness, tell us when to sleep and when to eat, and even trigger critical fight or flight responses. So it should come as no surprise that your body can do so much more than you think.

If you knew how hard your body and all its systems worked every day, you’d probably treat it better. Here are a few amazingly bizarre things the human body is capable of.

Your nose has a great memory

Have you ever walked into a room that just smelled familiar? That’s probably because your nose can remember up to 50,000 scents.

If it seems like the men in your life lose weight faster than women, that’s because men burn fat faster than women by a rate of about 50 calories per day. Many women would be happy to swap super powers.

Next: Your body is hard at work even when you’re resting.

You have the ability to lose weight while you sleep

Sleeping may feel restful, but for your body, it’s an opportunity to shed pounds. With each breath you take while you’re asleep, you emit water vapor that can contribute to a lower weight. It’s all water weight, of course, but that’s why it’s best to weigh yourself first thing in the morning.

Certain sounds can cause your pupils to dilate

Our pupils dilate if we listen to music that has a big emotional effect on us. And, if you listen to your “happy songs” while you study, you may retain more information.

It’s true. There is no muscle in your body that’s stronger than your tongue.

Next: You’re shedding right now. 

Your body sheds hair daily

Every day, the human body sheds about 60-100 strands of hair. You may only notice this if you have long locks.

Next: RIP, cells. 

Millions of your cells are dying right now

Every minute of your life, about 300 million cells in your body die. But don’t worry: Your body produces 300 billion new ones each day.

Your body can survive without food for over two weeks

The human body can survive about 20 days without food. Water is much more vital–you’ll die in about two days without it.

The skeleton is self-renewing. This means that ever 10 years, you will have grown a brand new one.

Your feet sweat … a lot

Human feet have about 500,000 sweat glands. This means they can produce more than a pint of sweat every day.

Your achy joints actually can predict the weather

Some people’s aching joints are actually great predictors of the weather. The atmospheric pressure drops when a storm front moves in, and major joints’ sensory nerve endings can register the increase in joint fluid pressure. This explains the “psychic joint” phenomenon.

Your heart rate can predict the future

Findings from a recent study show that some people’s hearts can anticipate certain events with no cues. Subjects were shown a series of images in an unpredictable order. Researchers discovered a quickened heart rate as much as 10 seconds before the presentation of a stimulating image, suggesting that hearts can sense when something thrilling or disturbing is about to happen.

Next: The eyes have it.

Your pupils reveal when you’re in love

When you’re in love with someone, your pupils tend to dilate when you see the person. The sympathetic nervous system, which controls pupil dilation, is to blame.

Your hearing is less sharp after a big meal

If you eat a little too much, you won’t hear quite as well for awhile. If it seems like everyone is shouting after Thanksgiving dinner, this may be why.
