Exercise

• When you exercise, your heart rate becomes faster and your muscles are working hard so your body temperature begins to rise. Perspiration is a result, because your body is attempting to cool itself down. Some people may sweat more when they exercise because of genetic factors. However, it is common for everyone to sweat when they work out. If you do not like the feeling of being sweaty after difficult exercise, consider exercising in a swimming pool -- the cool water will eliminate your body's need to perspire.
  
  

Warm Temperatures

• When the temperature is extremely hot, such as a sauna or outside on a summer afternoon, your body will perspire. Similar to exercise, your body must find a way to cool its temperature down and sweating is the way that it knows how to do this. Too much perspiration when temperatures are hot could mean that your body is becoming dehydrated. Always drink water when you are in extremely warm or hot conditions -- this will keep you hydrated.
  
  

Fever

• A fever is another common cause of perspiration. As your body tries to cool down your abnormal temperature it sweats. Because you are unable to escape a fever like you could hot temperatures or strenuous exercise, perspiring as a result of fever can be dangerous if it goes on for too long. Consume plenty of fluids while you have a fever so that your body can easily stay hydrated.
  
  

Caffeine

• Caffeine can also cause your heart to beat more rapidly, increasing your body temperature and leading to excessive perspiration. Caffeine can also make you anxious, which leads to perspiration in some people. Avoid drinking too much caffeine if you know that you get dehydrated easily. If you must consume caffeine every morning to help you wake up, make sure you also drink plenty of water throughout the day -- and notice if you are sweating too much.
  
  

Palmer Hyperhidrosis

• Sometimes excessive sweating is caused by a physical condition. Palmar Hyperhidrosis is a condition that causes excessive sweating of the hands and can also cause excessive sweating of the face, underarms, groin and feet. This physiological condition is rare and research has led many doctors to believe it is hereditary. There are many different treatment options to help alleviate the symptoms of this condition, ranging from simple antiperspirants to surgery. People with this condition should speak to their doctor about the treatment that is best for them.
