The body is made up of 60% water. We are constantly losing water through our breathe, sweat, urine, and bowel movements. This is why drinking water is so important – we have to constantly be replenishing it.
Dehydration is frequently caused by diarrhea, excess sweating, or vomiting. These causes are often due to the body’s inability to regulate temperature or illness. When you are dehydrated, you may have a dry mouth, feel fatigued, or feel dizzy. Your urine may also appear darker than normal. Severe dehydration can lead to low blood pressure, loss of consciousness, an increased heart rate, fever, and even, death.
On average, most adults should drink 2 litres of water per day to avoid dehydration. This may increase on hotter and humid days.
