Sweating–Your Body’s Cooling System
Most folks realize they sweat more when they exercise and that in order to stay healthy,
they need drink water. However, many society aren’t aware of how much water they need
to drink and why it’s crucial to so.
When engaged in physical activity, body temperature rises as much as 3 degrees. Your
body’s natural cooling system, sweating, kicks in to lower body temperature. Under
extreme exercise and heat stress, a body can lose 1/2 a gallon of water per hour.
whether the lost water is not replaced, dehydration occurs and serious consequences may
follow.
To understand what happens, I’ll use the analogy of your car. When your car’s cooling
system is running smoothly, excess heat from the engine is transferred to the water
in the tubes, which goes to the radiator to be cooled by the air. The cooled water
goes back to be heated once again by heat drawn from the engine. whether there is not decent
water in the system to allow for proper heat dissipation, your engine overheats, your
car stops running, and you are left cursing at the side of the road.
Now picture your body as the car– your muscles are the engine, your skin is the radiator
and your blood vessels are the water tubes that connect the engine with the radiator.
When your cooling system is running smoothly, excess heat from your muscles is drawn
into your blood vessels where is circulates to your skin. Evaporating sweat draws
heat away from the blood vessels. The cooler blood next recirculates all through the
body, lowering body temperature.
When too much water is lost through sweating, your blood volume decreases. that decreases
blood pressure which, in turn, reduces blood flow amidst the muscles and skin. To
overcome that, your heart rate increases. considering less blood reaches the skin, heat
loss is reduced and the body overheats. Just like your car, your body can quit running.
whether you fail to replace the water you lose, you run the risk of becoming dehydrated.
When a person is dehydrated by more that 4% or 5% of body weight, their exercise performance
declines by 20% to 30%. Not only that, the impact of dehydration on the cardiovascular
system can produce heart problems in citizens with coronary heart disease and diabetes.
Dehydration is plus hard on the kidneys.
How do you prevent your body from “breaking down”? It’s simple. You need to put in
as much water as is going out. Sweating is not the only way you lose water. Another
is through respiration– you lose water every instance you exhale. that water loss increases
as your physical activity increases considering you breathe more. So whether you are just replacing
how much you are sweating out, it’s not adequate. additionally whether you just drink when you are
of a body’s fluid needs.
Generally speaking, you should drink water before, during, and after exercise. Drinking
about 2 cups (16-oz.) of water one hour before, and 1 cup 1/2 hour before is a good
start. soon after you should drink 1/2 cup to 1 cup or more, every 15-20 min. The amount
depends on the air temperature, your body weight and how hard you are exercising.
Drink up! Show the citizens you exercise with that you know how to keep your body running!
