Sweating Is Good Even If It Looks---And Smells---Lousy

With heavy physical activity, you can feel the kick in the body temperatures by several degrees Celsius. That is the body's air conditioning system, when 'sweat' kicks in. If the sweat doesn't cool down our bodies, our basic temperatures too will shoot up, while our vital organs will get "cooked", according to indianexpress.com.

Exercise makes energy to activate our muscles as well as other metabolic processes. With high physical stress and energy levels, our internal temperature also shoots up. Our brain gets a 'bio-physics' alert and signals our blood vessels to remove our core body-heat through conduction. It automatically dilates the blood vessels and increases the blood flow towards the skin.

Still, there are about 2.6 million sweat glands on our skin which are able to sense the heat, shift in and begin to produce the sweat that evaporates from the skin.

"When you sweat, your pores open and release the grit and grime that has built up inside of them," says Whitney Bowe, MD, a dermatologist in Briarcliff Manor, New York, according to fitnessmagazine.

Outside, in the sweltering heat, the body will begin to manufacture the sweat that can shield us from the heat stroke. In order to replace the sweat, we need to consume litres of water.

To remain hydrated as well as prevent dehydration, it is important to replace the water during as well as after exercise. Beware of "dark colored urine, muscle cramps, decreased sweat rate, and increased fatigue," which may signify dehydration.

Water is a huge cleaning agent, that can help us to sustain bio-chemical reactions, remove waste, maintain circulation as well as the body's temperature levels. While the human body is made of two-thirds of water and one-third 'matter', about 60 percent of the weight is due to the solvent that is present in our cells, muscles, tissues and blood.

Hence, for a person weighing 70 kilograms, the body contains about 40 to 46 liters of water, depending on the gender, body-fat and fitness of the person. While 65 percent of our body's water is inside our cells, and 35 percent is outside, about 28 percent is floating between the cells and just 7 percent is in the blood.

Hence, with only 2.8 litres out of 40 liters of water in the body, it needs to maintain the blood volume, which transports oxygen to the entire body. As several liters of sweat to cool the body are drawn out, they need to be replaced fast.
