The Benefit Of Sweating That Doesn't Stink!

Sweating is crucial to managing body temperature whilst exercising, and now that we’re leading into summer, the effect of exercising in hot conditions is even more significant.

When body temperature increases, the body’s sweat glands kick into gear to keep our body temperature stable. When our core temperature increases, the hypothalamus (our bodies in inbuilt thermostat in the brain) triggers the sweat glands to release a mix of sodium chloride, electrolytes and water. 

Water plays a massive role in maintaining blood volume, regulating body temperature and allowing muscle contractions to take place. During exercise, the main way the body maintains optimal body temperature is by, you guessed it, sweating!  

When sweat leaves the skin’s pores, it evaporates into the air, taking some heat with it. This evaporation is what actually cools down the body. Sweat production, and therefore fluid loss, increases with a rise in ambient temperature and humidity, as well as with an increase in exercise intensity.

It’s not only body temperature that regulates sweating. During exercise, heart rate and blood pressure increase, which in turn cause the body to pump out more sweat.

Just because you sweat a lot, does not mean you’re less fit. Everybody regulates their body temperature differently- and some people may actually be more efficient at getting rid of heat by sweating more, go figure.

So, since sweating results in a loss of body fluid, it’s essential to drink lots of water before, during and after a workout to replace fluids lost in sweat. 

This action will reduce the risk of heat stress, maintain normal muscle function, and prevent performance decreases due to dehydration. During intense exercise, the rates of sweat loss are higher than the rate you can drink, which can result in a fluid deficit.

As long as you drink you recommended daily requirement of water of at least 2 litres, and then more when exercising intensely, you should be good to go!
