zweet weetjes (Engels)

Bericht door Thijs »

- The average person has 2.6 million sweat glands in their skin. The glands are distributed over the entire body - except for the lips, nipples and external genital organs.

- We have two types of sweat glands: eccrine, which produce volumes of the watery stuff, and apocrine, which produce tiny amounts of thick odorless fluid.

- We have eccrine glands all over our bodies, including the palms of our hands, the soles of our feet and our foreheads.

- We have apocrine glands under our arms and in the genital area. Breasts have a modified version of the apocrine gland. When the thick odorless fluid from our apocrine glands sits on our skin, bacteria act upon it, which is what makes us smell.

- Apocrine glands contain proteins and fatty acids, making their secretions thicker and giving them a milky or yellowish color. That's why underarm stains in clothing appear yellowish.

- Apocrine glands develop during puberty, which is why children don't need deodorant or antiperspirant.

- Men tend to produce more sweat than women.

- Ever wonder why you can't handle hot days in the spring as well as you can in late summer? It seems that your sweat glands need time to acclimate. A person who hasn't been in a hot climate for awhile can produce about one liter of sweat an hour. After about six weeks of hot weather, however, he or she will be able to produce two to three times that amount. (Anecdotal evidence suggests that people who sweat a lot while exercising year-round are automatically acclimated in the spring and thus able to handle the heat better.)

- About 3 percent of the population suffers from hyperhidrosis (excessive sweating). It most commonly affects underarms, hands and feet and can mysteriously strike in the coldest of conditions.

- We are constantly sweating, even though we may not notice it.

- The humidity of the air around us affects the rate at which sweat evaporates. If humidity is high, the air cannot absorb any more moisture and our sweat won't evaporate and cool our bodies as efficiently as when the air is dry.

- Losing excessive amounts of sweat can quickly dehydrate you, leading to circulatory problems, kidney failure and heat stroke.

- Never wear a plastic sweatsuit or lots of warm clothing while working out on a hot day. You won't burn any more calories, but you will lose lots of water weight, which can precipitate heat stroke.

- Sweat is made from fluid in your blood, which means the more you sweat, the thicker your blood becomes and the harder your heart has to work to pump that blood.

- People who are more fit are better able to cope with low or even moderate degrees of dehydration than those who aren't fit. Alberto Salazar finished the 1984 Olympic Marathon in 2 hours 14 minutes despite losing 8.1 percent of his body weight in sweat.

- An hour or two before exerting yourself outdoors in the heat, drink 16 ounces of water or sports drink, then take in between 5 and 12 ounces every 15 to 20 minutes while working or exercising, says Runner's World magazine.

- Americans spend more than $1 billion a year on antiperspirants and deodorants. Anti-microbials in deodorant help eliminate bacteria on your skin's surface, while fragrance helps mask odor. Antiperspirants help control sweat by forming gel plugs in some of our sweat glands.

- According to a recent New York Times report, most Japanese have almost no body odor. There was a time when Japanese men who had it were reportedly kept out of the military, because bodily smell ran contrary to the Buddhist idea of purity.

Je zou haast hypotheseren dat mensen met hyperhydrose eerder / fermer / vaker / langer lijden aan hart- en / of vaatkwalen.

Dat je hart harder moet werken hoeft niet altijd negatief te zijn. Vaak is het juist zo dat je hart dan goed ontwikkeld is en sterker is. Het hart is tenslotte ook maar een spier. Misschien dat de vaatwanden wel sneller beschadigen doordat ze onder hogere druk staan... Gezellig vooruitzicht!
