BROWNSVILLE (NEWS CENTER 23) — Today, I decided to hit the gym, only because I think it's time to shed a few pounds.
It really doesn't help too much that we have food in the newsroom almost everyday, temptation is truly my worst enemy!
As I was working out, you obviously build up a sweat.
But it's very different when you work out in an area where the heat is dry, compared to an area where the humidity is pretty high.
Did you know, that your body burns about 2,000 calories, and of course when you are exercising heavily, your body burns a lot more.
To translate this even further.
During your waking hours, you are burning about 2 calories per minute.
Throwing math in, these two calories have the ability to raise the temperature of 1 kilogram of water 2 degrees Celsius.
This means that if you weigh about 110 pounds, your body temperature rises one twelfth of a degree ferinheight every minute.
So imagine, you are working out and you are burning calories, which means your body temperature is heating up.
Obviously your body needs a way to dump that excess heat because if it doesn't, the body temperature rises into the danger zone in a matter of 30 minutes!
Did you know that at 80 degrees, it is easy to dump excess heat simply through radiation?
I am sure you have heard that the air temperature "feels" comfortable at about 80 degrees ferinheight.
And it's true, any hotter and it becomes harder for your body to cool off.
As a matter in fact, once the temperature rises above 80 degrees, your body does not have enough surface area to get rid of the heat fast enough so your body turns on your sweat glands other wise known as "evaporative cooling". http://science.howstuffworks.com/nature/climate-weather/atmospheric/ques... 
In areas like El Paso, TX where the air is dry, evaporative cooling works amazing.
That is why for me, I don't sweat so easily in El Paso. Besides the fact that its sunny about 80 percent of the time, I truly enjoy the desert weather.
But once you reach an area where the humidity is high like Brownsville, this process doesn’t work too smoothly.
The sweat cannot evaporate because the air is too saturated with humidity.
This is why the heat index is especially important to areas like these, in order for the public to be aware of how hot it is outside and if it'll get dangerous to be out long periods of time.
The heat index map calculates how it would "feel" if the humidity wasn't as high.
In fact, the heat index takes the day's temperature and humidity into account and calculates what the temperature would be if the air were at 25-percent humidity.
By the way, 25 percent humidity is really really dry, it's the kind of relative humidity you would find in a desert environment, like El Paso!
On this scale, high humidity can make you excruciatingly hot because again, your body has no way to eliminate excess heat.
For example, 100 degrees F with 100 percent humidity is the equivalent to 195 degrees F at 25 percent humidity!
This is nearly the boiling point of water!
That is why this scale is extremely important for people to understand if they have pets outside!
I have said this many times before, I hate the cold weather, but in a humid area, I think I would definitely change opinions. There is no way I could be ok in 195 degree weather!
