Why do you feel queasy when you exercise? Nowadays, many people begin to like sports and fitness. Some people exercise in the morning, thinking that it can have a good exercise effect, but sometimes they feel sick when exercising. What happened? Let's see why we feel queasy during exercise.

Why do you feel queasy when you exercise?

hypoglycemia

Exercise on an empty stomach leads to insufficient heat supply and hypoglycemia, which in turn leads to discomfort such as nausea, vomiting and dizziness.

Note: You can eat some digestible food before exercise, such as bananas. If you are a patient with hypoglycemia, you can carry candy with you and replenish it in time when you feel dizzy and sick.

Lack of water in body

When you exercise on an empty stomach, you will produce a lot of nitrogen-containing waste and ketone bodies in your body. In order to excrete these wastes, your body will further produce urine and increase the amount of urine excreted, so dehydration will occur. At this time, the body is in a crisis of insufficient energy and water, and dizziness and vomiting will occur.

Attention: Appropriate amount of water should be added during exercise, and some light salt water should be added in time after exercise to supplement the lost inorganic salts.

Suffer from blood pressure disease

If people have low blood pressure or high blood pressure, they are more prone to nausea, dizziness and vomiting after exercise, not to mention exercise on an empty stomach.

If the blood pressure is too low, there will be less blood supply to the brain after exercise, leading to dizziness and vomiting. If the blood pressure is too high, strenuous exercise will lead to further increase of blood pressure, compression of blood vessels and physical discomfort.

Note: people with blood pressure diseases should monitor their blood pressure at any time, exercise moderately, and do not exercise on an empty stomach.

Excessive exercise

When the amount of exercise on an empty stomach is too large, the brain will automatically allocate energy and resources to the exercise system and muscles to slow down or stop the system unrelated to exercise. The digestive system is one of them. Food in the stomach lacks energy to decompose and absorb. When the amount of exercise is large and lasts for a long time, this part of food will be regarded as a burden, and then it will vomit by stimulating the gastric nerve.

Note: Adjust the intensity of exercise, and your body will not feel uncomfortable.

Irritation to the stomach and intestines

Running in cold weather, cold air is easily sucked into the stomach, which is more irritating to the stomach. A person's stomach will twitch after catching cold, which will make the gastric juice upwell and cause nausea and vomiting.
