From a physiological perspective, sweating is absolutely a good thing. Our body would overheat if we did not sweat. But some of the activities that cause sweating (excessive time in the heat, being nervous or sick) is associated with other problems, such as heat exhaustion, anxiety and illness.
“Their bodies adapt in response to hot or humid environments.” So sweat is complicated. But most of the research suggests perspiring in response to heat or exercise—whether you sweat a little or a lot—doesn't mean much about your health.
It's normal to sweat if you get hot or do exercise, but you may be sweating excessively if you're sweating when your body does not need to cool down. Excessive sweating can happen for no obvious reason, because of another condition you may have, or as a side effect of a medicine you're taking.
Usually, excessive sweating is not associated with illness or disease, but occasionally there is a medical reason that might cause you to sweat excessively. Your doctor can help you understand the cases of your hyperhidrosis, check for any underlying conditions and suggest treatment and management options.
In hyperhidrosis, your body's sweat glands overact. This overactivity causes you to sweat a lot, at times and places where other people wouldn't. Sometimes, a medical condition or emotion (like anxiety) triggers excessive sweating. For many people with hyperhidrosis, managing symptoms can be a constant challenge.
While sweating doesn't burn fat, the internal cooling process is a sign that you're burning calories. “The main reason we sweat during a workout is the energy we're expending is generating internal body heat,” Novak says. So if you're working out hard enough to sweat, you're burning calories in the process.
Therefore, sweat is not made up of toxins from your body, and the belief that sweat can cleanse the body is a myth. “You cannot sweat toxins out of the body,” Dr. Smith says. “Toxins such as mercury, alcohol and most drugs are eliminated by your liver, intestines or kidneys.”
Through filtering out toxins when we sweat, like alcohol and waste products, it helps boost our immune system. Plus, physical activity can help flush bacteria from the body and slow down the release of stress hormones which can both cause illness.
Botulinum toxin: Another treatment option for heavy sweating is injections of botulinum toxin A (Botox), the same medicine used for wrinkles. Botox is FDA-approved for treating excessive sweating of the underarms, but some doctors may also use it on the palms of the hands and soles of the feet.
In general, sweating means your basal metabolic rate is higher, and you are exerting enough energy to make your muscles work harder. This causes your body to produce more sweat in order to cool down its internal temperature as it evaporates from your skin.
Your body also increases the overall rate at which sweat can be produced. Put simply, as you get fitter, you can work harder and produce more heat, so the body responds to this by 'ramping up' its sweating response and by starting to sweat earlier in order to reduce the risk of overheating.
It's usually nothing to worry about - sweating from your face, head or scalp is natural. When we exercise or get too warm, our bodies release sweat to cool us down. Head sweats can also be triggered when you're nervous or stressed.
Hyperhidrosis is a medical condition in which a person sweats excessively and unpredictably. People with hyperhidrosis may sweat even when the temperature is cool or when they are at rest.
Sweat is an indication of proper organ function and nervous system response. If you're sweating, your body can cool and regulate itself to keep working properly. But if you're experiencing changes in body odor, excessive sweating or not sweating at all, it's time to check with the doctor to make sure everything's OK.
Healthy Hair Growth
Researchers agree that too much sweat can be dangerous, but the same study suggests that sweating promotes hair growth. After a heavy workout, your body will sweat a lot, and this helps unclog the hair follicles. What this means is that there will be more space for new hair to grow.
Body odor happens when bacteria on your skin come in contact with sweat. Our skin is naturally covered with bacteria. When we sweat, the water, salt and fat mix with this bacteria and can cause odor. The odor can be bad, good or have no smell at all.
In ordinary circumstances, physiologists agree, sweating has a minor role in waste removal. The main exception occurs in kidney failure, when sweating removes more of the mildly toxic waste product urea, which the liver produces in breaking down amino acids and which the kidneys normally excrete efficiently.
Does Sweating Burn Belly Fat? While sweating can be an indication of an intense workout, it's not a direct indicator of fat loss, and sweating alone won't cause you to lose belly fat. Instead, sweating is simply a mechanism for regulating body temperature and removing excess heat from the body during exercise.
As you sweat, you naturally lose water; it seeps from your pores onto your skin, reducing any internal water retention. As you won't be carrying as much fluid weight, your body will feel lighter and look thinner, but these results may be temporary.
Being overweight causes many problems as it forces the body to work double-time in order to function properly. This often causes excessive sweating. As the heart pumps harder to receive oxygenated blood cells, it raises the body temperature, resulting in sweating.
