Sweating: How Much is Too Much?

Sweating cools your body and keeps it working at optimum levels, but too much liquid loss can lead to dehydration. When you become dehydrated, even slightly, your body lacks the nutrients and essential liquids to keep your muscles working correctly. Prolonged dehydration has lead to fainting and even death in extreme cases.

Sweating During Exercise

Sweating occurs much more often while you’re exercising than when you remain at rest. Sweat glands push water, sodium, potassium and chloride to the surface of your skin because an overload of these ingredients will not get reabsorbed into your dermal layers. When at rest, your body has enough time to take the liquids and nutrients back into its glands for storage.

Excessive sweating simply means that you continue to increase your body’s internal temperature at a steady rate. The body sweats out the liquids so that they will evaporate, which in turn cools the body down.

Many people connect weight loss with sweating, as a loss of liquid from the body does, in fact, decrease the numbers on the scale. However, the essential liquids that you lose during sweating must get reintroduced into your system in order for you to actually lose some of the fat that’s in your body.

Plus, without consuming liquids after sweating, your muscles will not work to their full potential. You also increase your risk of heart damage since the cardiovascular muscles must work harder in order to circulate the thickened, nutrient-depleted blood.

Avoiding Dehydration

As mentioned early, without proper hydration, your muscles start to decline in performance. Becoming completely dehydrated will literally cause your body temperature to rise until the point of shut down–just like a car when its engine becomes overheated. Throughout your workout routine, continue to drink plenty of liquids.

You will also have a much higher chance of experiencing dehydration when performing moderate to vigorous physical activity in high temperatures. Many athletes suffer from heat exhaustion, a form of dehydration caused directly by an inability to identify liquid loss. When conditions become too hot, the sweat that reaches the surface of the skin quickly evaporates. This makes athletes believe that they have not lost much sweat because their clothes stay dry and so does their skin.

Wearing light colored, lightweight garments in hot environments will enable you to stay cooler for longer periods of time. This also helps fend off extreme sunlight absorption which is detrimental to the skin. Too much sun exposure can cause age spots and skin cancer. It’s also a good idea to wear loose fitting clothing that allows the skin to breath. In addition to being more comfortable during physical activity, garments that constrict air flow literally cause the skin to suffocate. Your pores lose the ability to properly perspire.

Other Tips

Always continue the hydration process throughout your exercise sessions and after your workout as well. Staying hydrated throughout the day allows for optimal weight loss and healthy sweating, which can help prevent fatigue and dehydration.

    I work in a warehouse that is very hot and have done so since August 2010. I have lost 30 pounds and all of my upper body mass. I am nothing but skin and bones. How can I get my body mass back? I’m on my feet for 8 hours a day and very physical work.
