Have you ever felt nauseous or dizzy after exercise? This condition can happen to anyone, both beginners and those who are regularly exercising every day.

This is because nausea that occurs is caused by various factors in each individual's body. If left alone, nausea can interfere with sports performances and make the body feel weak.

Therefore, it is important to know the cause of nausea and how to deal with it, as below, quoted from Verywell Health, on Friday, October 3, 2025.

1. Dehydration

Nausea after exercise can occur because the body is dehydrated or lack of fluids. When sweating, the body can lose a lot of fluids and important electrolytes.

If not replaced immediately, organ function can be disrupted and nausea in the end appears. Dehydration can also trigger a faster heart rate and inhibit blood circulation.

To overcome this, make sure you still fill your body's fluids by drinking enough while exercising. Choose to drink with electrolyte if you practice more than an hour, drink a little but often better than drinking one drink at a time in large.

2. Eating too close to sports time

Eating especially with a heavy portion too close to exercise time can make digestion work extra. When the body needs to focus on flowing blood to the muscles, a full stomach can trigger nausea.

Therefore, you should give the break two to three hours after eating before starting exercise. If you really have to eat for additional energy before exercise, then choose light snacks such as yogurt and bananas.

3. The intensity of the sport is too high

Exercise with too high intensity or excessive can make the body overwhelmed. Changes in directional pressure and buildup of lactic acid in muscles often trigger nausea.

This is usually experienced by beginners who are not used to the heavy exercise load. If forced, it can trigger disturbances in the digestive system.

To overcome this, start exercising with moderate intensity, then gradually increase it so that the body has time to adapt. Also listen to signals from your body, don't force it to run out of energy.
