Chest tightness when swimming

Because swimming uses muscles throughout the body to move forward, it can have a good shaping effect on some muscles in the human body. Therefore, swimming has become an increasingly popular form of sport, especially in the hot summer when soaking in a swimming pool is very cool. However, some people will experience some abnormal physical conditions when swimming, that is, chest tightness. So what causes chest tightness when swimming?

1. What is the reason for palpitations, shortness of breath and chest tightness after swimming?

1. Hypoglycemia

The early symptoms of hypoglycemia include palpitations, fatigue, hunger, hand tremors, cold sweats, pale complexion, cold limbs, or nausea and vomiting, which are mainly caused by excessive excitement of the sympathetic nerves and excessive adrenaline. Hypoglycemia is episodic, not frequent, and rarely causes symptoms of chest tightness and shortness of breath.

2. Anemia

Anemia can cause symptoms such as dizziness, palpitations, and tachycardia, but generally does not cause symptoms of chest tightness.

3. Low blood pressure

It also mainly causes dizziness, but the blood pressure is around 60/90, which generally does not cause changes in blood supply.

2. It is best not to swim during these periods

1. Avoid swimming before or after meals: Swimming on an empty stomach will affect appetite and digestive function, and may also cause unexpected situations such as dizziness and fatigue during swimming; swimming on a full stomach will also affect digestive function, and may also cause stomach cramps, and even vomiting and abdominal pain.

2. Avoid swimming after strenuous exercise: Swimming immediately after strenuous exercise will increase the burden on the heart; the sudden drop in body temperature will weaken resistance and cause colds, pharyngitis, etc.

3. Avoid swimming during menstruation: Swimming during menstruation can cause bacteria to easily enter the uterus, fallopian tubes, etc., causing infection, leading to irregular menstruation, excessive menstrual flow, and prolonged menstruation.

3. Skin's reaction period to cold stimulation

Phase 1: After entering the water, the skin's blood vessels contract due to the stimulation of cold, and the skin color becomes pale.

Phase 2: After staying in water for a certain period of time, the blood flow on the body surface expands, the skin turns from pale to light red, and the skin turns from cold to warm.

The third stage: staying too long, the body temperature dissipates more than the heat generated, and goose bumps and chills appear on the skin. This is a taboo period for summer swimming, and you should get out of the water in time. Swimming should generally not last more than 1.5 to 2 hours.
