4 Facts About Your Body You Didn't Know

1. Sweat

Sweat helps to keep our body temperature regulated. Women tend to have more sweat than men, but men's sweat glands are more active. That's just because us ladies know how to keep our cool ;). We tend to think that sweat just comes from our armpits when we exercise, but a recent study actually found that researchers could get DNA out of a fingerprint because there were cells shed that stuck to the surface of the fingerprint with sweat. Amazing! Just think some crazy scientist could be making clones of you this very second, all from your fingerprint. Eeek!

2. Hair

This might sound scary but the average person loses about 80 hairs a DAY! Often more towards the end of summer, and they end up everywhere, but if your like me they mostly clog up the shower drain. It's normal really if you think about it, all the agitation to your scalp and pulling of the hair. It seems like more hair falls out if you haven't washed your hair in a few days. Although If you’re experiencing excessive hair loss, you could have a hormonal imbalance. “With polycystic ovarian syndrome, women have too much testosterone and start losing hair in the male pattern, off the top of the head and the sides of the forehead,” Mansberg says. “Iron deficiency can also lead to hair loss, but often if we correct the iron deficiency, their hair is much better.”

3. Bacteria

Did you know there are up to 1000 different types of bacteria living in our skin! They help our skin cell turnover and immunity, and we leave traces of them wherever we go! Yuk. No two people have the same combination, we are totally unique. :) Because of the uniqueness, scientists are investigating using samples of bacteria from our palms to get a reading that could one day replace or be used alongside criminal forensic evidence. “They’re talking about using a bacterial footprint instead of fingerprints”.

4. Skin

Our skin is amazing! Not only does it serve to protect us it has also been found to help absorb harmful pollutants from the ozone, fascinatingly an oil called squalene in human skin cells “gobbles up” a small amount of air pollution from our homes. Pretty neat! So that's just another reason to look after it well. It's like a conveyer belt and it works better if it is run smoothly. The body is made up of 1.6 trillion skin cells and we lose and replace between 30,000 and 40,000 a hour, with it fully regenerating every 30 days.
