Answer:
2-Water helps maintain body temperature.
3-Diuretics like alcohol and some medications can cause the body to lose water.
Explanation:
Dehydration occurs when the amount of what loss is more than the amount taken. And we lose water in many ways therefore taking water on a regular basis is important to replace the fluids lost and keep the body functioning.
Water Maintains the Body Temperature
During high temperature, the body cools itself naturally by sweating and by sweating a large amount of water is lost. So when enough water is not taken, there will be less production of sweating thereby causing the body's temperature to rise.
Alcohol Causes Water Loss
Taking excess alcohol can result to dehydration because the hormone called anti-diuretic (while alcohol is diuretic) is used to reabsorb water by the body and alcohol in the body depletes the production of this hormone. The body loses more water than normal with a reduced amount of anti-diuretic in the body. Excessive intake of alcohol can also cause vomiting, which depletes the body of fluids and can cause further dehydration.
