Dehydration occurs when you use or lose more fluid than you take in, and your body doesn't have enough water and other fluids to carry out its normal functions.
Good hydration is important all the time — especially when you’re working out.
If you don’t drink enough fluids before, during, and after exercise, particularly when you’re sweating a lot, you could become dehydrated.
Muscles do not grow if you do not drink water during exercise.
So it is very important to drink water while exercising.
Dehydration happens when your body doesn't have as much water as it needs. Without enough, your body can't function properly. You can have mild, moderate, or severe dehydration depending on how much fluid is missing from your body.
It’s normal to lose water from your body every day by sweating, breathing, peeing, and pooping, and through tears and saliva (spit). Usually you replace the lost liquid by drinking fluids and eating foods that contain water. If you lose too much water or don’t drink and eat enough, you can get dehydrated.
Babies and young children are the most likely to have severe diarrhea and vomiting, and they lose the most water from a high fever. The youngest can’t tell you they’re thirsty or get their own drink.
Older adults often don’t realize they’re thirsty. If they can’t get around very well anymore, they may not be able to get a drink easily or may not be able to take in enough fluids due to medical conditions.
People who are ill with a cold or sore throat may not want to eat or drink.
People with a chronic disease such as type 1 or type 2 diabetes can pee a lot if the disease is uncontrolled. They also may take medicines such as water pills, which make them go more often.
People who are active outside in hot and humid weather sometimes can’t cool down effectively because their sweat doesn’t evaporate. This can lead to a higher body temperature and need for more water.
Swollen ankles and swollen feet are common and usually not cause for concern, particularly if you have been standing or walking a lot. But feet and ankles that stay swollen or are accompanied by other symptoms could signal a serious health problem. WebMD looks at some possible causes of foot and ankle swelling and offers advice on when to call the doctor.
Pregnancy complications. Some swelling of the ankles and feet is normal during pregnancy. Sudden or excessive swelling, however, may be a sign of preeclampsia, a serious condition in which high blood pressure and protein in the urine develop after the 20th week of pregnancy. If you experience severe swelling or swelling accompanied by other symptoms such as abdominal pain, headaches, infrequent urination, nausea and vomiting, or vision changes, call your doctor immediately. Learn more about managing a high-risk pregnancy.
Foot or ankle injury. An injury to the foot or ankle can lead to swelling. The most common is a sprained ankle, which occurs when an injury or misstep causes the ligaments that hold the ankle in place to be stretched beyond their normal range. To reduce the swelling from a foot or ankle injury, rest to avoid walking on the injured ankle or foot, use ice packs, wrap the foot or ankle with compression bandage, and elevate the foot on a stool or pillow. If swelling and pain is severe or doesn't improve with home treatment, see your doctor. Learn more about how to treat a sprained ankle.
