24-Hour Virus

Physical Activity
When you exercise, the body loses a lot of water through sweat--especially in high temperatures. If you don't replenish this fluid loss, you can become dehydrated easily. Some of the symptoms are dizziness, dry skin and even unconsciousness.
Alcohol
Alcohol causes impaired judgment, slowed reaction time and can also lead to addiction. But it can also cause dehydration. Alcohol is a diuretic that flushes potassium out of the body, which causes thirst. Alcohol-induced dehydration can lead to faintness, muscle cramps and dizziness.
