How to avoid dehydration?

Dehydration can be avoided through the following steps:

1- Weigh yourself

First, weigh yourself before exercise and after using the bathroom.

Then, record your weight and after finishing the exercise, weigh yourself again.

Losing 2% or more of your weight is a sign that you are dehydrated.

2- Notice the color of your urine:

Note the color of your urine before and after exercise.

Aim for urine color 1 to 3 (as shown in the diagram below) before exercise, then note the color of your urine after exercise to estimate your dehydration and replace the fluids you lost during exercise.

3- Drink an adequate amount of fluids before, during, and after exercise

The appropriate amount of fluid for the body during your day is 8 glasses and increases by 1.5 during exercise.

4- Reduce the consumption of drinks that increase dehydration, such as:

Energy drinks and caffeine.

5- Pay attention to the dryness of your mouth

Drinking enough water may help you with the following:

Regulating body temperature.

Preventing joint friction.

Transporting nutrients within the body to provide it with energy.

Protecting the body against muscle spasms, dizziness, and fatigue.

Facilitating the digestive process.
