Do girls have perspiration during puberty?
Yes, most girls swet, perspirate during puberty. The reason is because their are oils in our skin and we sweat more in gym whe we run then if we are not running. If teenage girls are not sweating their foreheads will get very oily/greasy.
Why do you perspirate more in humid conditions?
1. Due to osmosis, or the diffusion of water particles, the water in the bodies cells are more likely to be released through your skin cells' permeable membrane. Hence perspiration is more likely to overcome the body. 2. During humid weather conditions, the body is, on low accounts, overheating from the inside. Hence perspiration is more likely to overcome the body.
How does sweating make you feel cooler?
The evaporation of the sweat is actually what cools you. The change from a liquid to a gas requires heat energy and it gets part of that heat energy from the skin, making the body feel cooler. Perspiration takes excess heat from your body and releases it to the surface in moisture. A secondary mechanism continues to cool the body as the moisture evaporates from the surface of the skin. Cooling occurs in all types of climates but the evaporation mechanism works best in areas with low humidity because it exchange is more rapid.
Why do horses grow winter coats?
Horses usually mature at the age of 4-5. Often they reach full height at three, and then fill out when they are four and five, but it really varies depending on the horse. This also depends on the breed of horse as some breeds like Trakhners mature very slowly and take time. So they can actually add more height as they get older. Thier are cases of some warmblood horses still growing in size until they are as much as 8-9 years old. Draft horses and any breeds that mature extremly slow can take a long while to mature and grow. Many western horses (Quarter horses/Paints) are often full grown at 6 or 7 years old In the U.K. horses can only get a Life Height certificate at the age of 7. Until that time they can get annual height certificates. Most horses/ponies continue to grow until they are 7 years old.
