Thank you for using the Jiskha Homework Help Forum. You definitely do not want do dehydrate. That is why many people heavily involved in sports drink Gatorade to replenish their electrolytes.

Staying properly hydrated is crucial when working out or doing sports for several reasons:

1. Replenishes Fluid Loss: Physical activity causes sweating, leading to fluid loss. Drinking water helps restore and replace this lost fluid, helping to maintain your body's overall fluid balance.

2. Enhances Performance: Dehydration can negatively impact your athletic performance. When you are dehydrated, your blood volume decreases, leading to reduced oxygen delivery to muscles and decreased energy levels. Drinking water helps to prevent this, allowing you to perform at your best.

3. Regulates Body Temperature: Sweating during exercise helps to cool down your body. However, if you become dehydrated, your body may struggle to regulate its temperature, increasing the risk of heat-related illnesses.

4. Prevents Cramps and Fatigue: Dehydration can contribute to muscle cramps, fatigue, and a decline in coordination. By drinking enough water, you can reduce the likelihood of these issues occurring, keeping your muscles functioning properly.

So, to ensure you stay properly hydrated during exercise or sports, it is recommended to drink water before, during, and after your activity. Additionally, listen to your body's signals of thirst and drink accordingly. Remember, specific hydration needs may vary depending on the duration and intensity of your workout, as well as individual factors such as sweat rate and climate.
