If You Don’t Sweat During Exercise, Is It A Waste Of Time?

Thursday, April 15th, 2010

 

You always hear the old adage, “lets go exercise and work up a good sweat” like sweating is a sign that you’ve had a good, productive workout. But what if you exercise and you don’t really sweat during the workout? Was that workout a lost cause? Does it mean you just didn’t exercise long or hard enough for it to be a productive workout?

Well let’s examine the facts here and dispel the ever popular myth about just why you sweat and it’s relation to exercise.

Your body is like an engine that never stops running and like all engines, it produces heat. The more your muscles contract, the more heat is produced. If the body didn’t have ways of keeping you cool, you would overheat and collapse within 20 minutes.

 

The first method is radiation where heat radiates out of the skin if the air around you is cooler than your body. The second method is conduction which is the transfer of heat by direct contact such as swimming in a pool of cold water where the water absorbs your body heat. The third method is convection where moving air cools us down like when you stand in front of a fan or when the wind blows. The last method is evaporation where water from our blood absorbs the heat and rises to the surface of the skin through the sweat glands so it can evaporate creating a cooling effect.

 

In colder conditions, you will not need to sweat as much due to the body using radiation to keep cool. In hotter conditions, sweating is the primary method of keeping cool due to the air being hotter than your body but if there is humidity present, sweat cannot evaporate as well and that’s why you will see sweat dripping off you. Since in these conditions sweat doesn’t evaporate, radiation and convection (remember the moving air?) are used by your body to keep cool.

 

Everyone has a different sweating pattern. Gender, age, fitness level and environment contribute to how much you sweat. Women seem to sweat less and start to sweat at higher temperatures than men. People tend to sweat less as they grow old and thus cannot take the heat as well as a younger person but declining fitness levels may have something to do with that. In laboratory experiments where both young and old people were of similar fitness levels, there was no notable difference in their sweating process.

 

If you exercise in an air-conditioned room or outside when it’s a cooler time of year, you will not sweat as much because the cold air evaporates your sweat faster and also sets your body up to use more of the radiation method meaning your body can deal with the heat created by exercise more easily. It does not mean you are not burning as many calories because the intensity and length of time of your exercise is what determines caloric burn, not how much you sweat. You are sweating all the time but you just can’t see it because it is always evaporating.

If it were true that the more you sweat, the more calories you burn during exercise then it would also be true that you would be burning more calories simply sitting in a hot, humid room so as to build up a sweat but this is obviously not the case as the sweat you would be seeing is due only to the conditions of the room not allowing for evaporation for cooling the body.

 

Exercise produces heat, heat produces calorie expenditure, and you produce the same amount of heat whether exercising in a cold environment or a hot one so just because you don’t sweat as much in the colder environment does not mean your exercise session was less productive.

 

Must Haves In A Woman’s Shoe Closet

Friday, March 19th, 2010

Shoes have habitually been available in a big variety and when it comes to women’s shoes, the range is just about infinite. You’ll find high heels to the almost flat balletdancers. For the shoe closet of a lady to be complete, there are some must haves. They’re detailed here.

When you talk of foot wears, a woman cannot do without a black pump. However, ideal is the one which has a very low heel. A black pump is as big a prerequisite as a LBD is for the woman’s wardrobe. They go with everything. You can easily wear them to an unscheduled formal meet. You can also team the black pumps with your fave LBD and rest assured you are going to look like million USD. When you are out purchasing the black pumps, make sure that you do not purchase the shimmery and the glittery version. This will ensure that you can simply wear them along with your formals as well.

When you talk about pumps, you can’t afford to luck out on the one which comes in the neutral colours. There are number of occasions when your black pumps do not go well with the dress you are wearing. In such a situation it is the neutral pumps which come to your rescue. No matter what color of the dress you wear, neutral pumps are the safe bet to go with. The most suitable choice in this context is the pumps which come in colors like rust, beige and pale golden or silver. These colours can go with everything.

Another must have shoe in your closet is a semi casual flat. Obviously you can not expect yourself to be decked up all the time in the best of clothing and accessories. It is at such times the semi casual flats come in useful. These studios work utterly OK with leggings and easy denims. You can get any easy and adorable pair of semi flats. All you must do is to slip on to slip on to them and you are all set to head to the close by market or can simply go out and catch up with your friends.

Just like you want shoes for the time when you are not officially dressed, you’ll also require a special pair for days and occasions when you dress up to your best. For such an eventuality, you want to get shoes with really high heels, those in metallic color or tone would do the best. Three color options – bronze, silver and gold are popular though silver suits the majority. You can wear them to parties confidently.

You also have to have 2 good comfortable sneakers in your shoe closet. Irrespective of what sort of wardrobe you have, a sneaker is a must. You will need them when you go off and do some shopping for vegetables or just want to take a stroll around the house. When purchasing sneakers go in for the ones that are extremely comfortable. If you like all things girlie, then sneakers in feminine colors like pink and red are a sensible choice.

Stock all these types of shoes in your shoe closet and you’ll never need to bother about teaming the right clothing with the right shoes.
