Definition Sweat electrolytes is a test that measures the level of chloride in sweat. Although genetic tests have become important methods for determining whether a child has cystic fibrosis, the sweat chloride test remains important. Alternative Names Sweat test; Sweat chloride; Iontophoretic sweat test How the test is performed In the first part of the test, a colorless, odorless chemical that causes sweating is applied to a small area on an arm or leg. An electrode is then attached to the arm or leg, which allows the technician to apply a weak electrical current to the area to stimulate sweating. People may feel a tingling sensation in the area, or a feeling of warmth. This part of the procedure lasts approximately 5 minutes. The next part of the test involves cleaning the stimulated area and collecting the sweat on a piece of filter paper or gauze, or in a plastic coil.

Reader: I really think I sweat too much. Why does this happen and what can I do about it now that warmer weather has arrived?
The more important question is this: When do you think you sweat too much?
If you feel you sweat too much when it's warm outside or you've exerted yourself, then your body is simply regulating its temperature. For example, if you've been walking outside for a few hours on a day when the temperature is 90 degrees Fahrenheit and you're sporting some embarrassingly damp armpits, you're sweating because you're hot and your body needs to cool down.

Do night sweats disrupt your sleep? Sweating at night isn't really a sleep disorder, but there's no doubt that waking up with nightclothes and bedding soaked with perspiration does disturb your nighttime slumber. One cause of night sweats or nocturnal hydrosis is menopause. Of course, if you are a man, this doesn't apply. And, believe it or not, it doesn't necessarily apply if you are a woman, either. There are many causes of night sweats. Even eating spicy food or drinking a hot beverage before bedtime can bring on a night sweat. Heartburn or gastroesophageal reflux disease is another possible cause. So is a bedroom that's too hot or sleeping under too many blankets. Other Causes of Night Sweats As we are dealing with sleep disorders, it should be noted that one cause of night sweats is obstructive sleep apnea. If you snore, suffer from excessive daytime sleepiness or are overweight, and you also suffer from night sweats, consider the possibility of sle...
