Why do I feel like vomiting after exercise?

Some people always have symptoms of nausea and vomiting after exercise. There are many reasons for this symptom. The most common one is that they like to breathe through the mouth during exercise, which causes excess air to enter the stomach and intestines, causing stomach cramps, which can easily lead to symptoms of nausea and vomiting. Therefore, you must breathe through your nose during exercise. In addition, some people lack exercise, and occasional high-intensity exercise often causes physical discomfort and symptoms of hypoxia, which causes symptoms such as dizziness and is also prone to vomiting. Therefore, if you usually do too little exercise, you must gradually increase the amount of exercise to avoid adverse reactions.

Causes of nausea after exercise

Lack of exercise

People who do not exercise regularly are prone to symptoms such as pale face, breathlessness, nausea, and vomiting when they exercise occasionally. This is because the body's organs cannot adapt to the occasional intense exercise, resulting in insufficient oxygen supply, which causes physical discomfort.

Excessive exercise

When the amount of exercise is large, the brain will automatically allocate energy and resources to the motor system and muscles, and slow down or stop systems that are not related to exercise. The digestive system is one of them. The food in the stomach lacks the energy to break down and absorb it. When the amount of exercise is large and long-lasting, this part of food will be regarded as a burden and then vomited out by stimulating the gastric nerves.

Insufficient body heat

When exercising in an environment that is too hot or too cold, or when exercising while hungry, the body will not get enough calories, and you will often experience nausea, vomiting, dizziness and other discomfort symptoms after exercise.

Caused by gastrointestinal irritation

When running in cold weather, it is easy for cold air to be inhaled into the stomach, which is quite irritating to the stomach and intestines. When the stomach is exposed to cold, it will spasm and cause gastric juice to rise up, resulting in nausea and vomiting. It is recommended not to breathe deeply through your mouth, but to breathe through your nose.

Rest after exercise

Many people stop to rest as soon as they finish strenuous exercise. A large amount of venous blood in the limbs will accumulate in the veins, causing the heart to be ischemic. The brain will also experience symptoms such as dizziness, nausea, vomiting, and shock due to insufficient blood supply and lack of oxygen.

Caused by physical illness such as hypoglycemia

Dizziness and nausea during morning jogging may also be caused by hypoglycemia. It is recommended to eat a banana or a glass of honey water to replenish energy before morning jogging.

In addition, people with anemia, hypertension, chronic rhinitis and other diseases often experience symptoms such as dizziness and nausea during exercise.
