Playing sports outside can cause extra sweating, but it's not necessarily a problem.
Sweating, also known as perspiration, happens when your body's sweat glands release a salty liquid, according to Medline Plus. Common sweating points include your hands, feet and underarms. Sweating helps keep your body cool, including when you become heated during exercise or while playing sports. It's not necessarily bad to sweat a lot when you're playing sports -- it could just be a sign that you're working hard during the game. However, excessive sweating can also signal a more serious health problem, so if you feel concerned about the volume of your perspiration, see a doctor.
Blame Your Glands
How much you sweat depends on how many sweat glands you have, according to Medline Plus. Women tend to have more sweat glands compared to men, but men's sweat glands are more active. A person can have between 2 million and 4 million sweat glands; these usually become active around the onset of puberty. You might notice that you sweat significantly more or less than others participating in the same sport around you, but that doesn't mean that you're working out harder or less strenuously than teammates or opponents, according to NBC News.
Sports and Weather
Your genes might not be the only explanation for your sweating. Because sweating is linked to your automatic nervous system, how much you sweat isn't within your conscious control. If you're playing sports outside, high temperatures could increase your sweating as your body attempts to cool itself, according to Medline Plus. NBC News states that the ideal temperature for working out indoors ranges between 68 to 72 degrees Fahrenheit; if it's hotter, you might notice additional sweating.
Sweating is also associated with certain emotions, such as anxiety or stress. You might find yourself sweating more before a big soccer game, or when you're taking an important shot during while playing basketball. Dressing inappropriately for your sport could also explain too much sweating. In some cases, certain medications can cause excessive sweating, according to the International Hyperhidrosis Society. Although you might notice sweating while playing sports, try to observe whether you're sweating on other occasions. Regular, excessive sweating could indicate effects from current prescriptions.
When It's Serious
Typically, sweating while you're playing sports shouldn't be an indicator that something is seriously wrong. If your sweating is accompanied by other symptoms, such as chest pain, fever or a rapid heartbeat, consult with your doctor, according to Medline Plus. If you experience shortness of breath or weight loss accompanied by excessive sweating, this could also signal that you should meet with your physician. Heavy sweating could signal heat exhaustion. Conversely, if you notice that your body has stopped sweating, this could signal dehydration or heat stroke, according to the Centers for Disease Control and Prevention.
