How many hours after a meal can you swim

Many people habitually go swimming after meals. Swimming can not only help us digest, but also increase muscle vibration to relieve body heat and promote weight loss. However, right after a meal, because the abdominal bloating is very serious, it is not recommended to swim too short after a meal. There are many types of precautions about shipping that need to be understood clearly.

01Avoid swimming on an empty stomach

Swimming on an empty stomach, due to low blood sugar in the body, is particularly prone to muscle tremors, dizziness, collapse, coma, and even collapse leading to drowning and other accidents.

Do not swim on an empty stomach. Before swimming, swimmers should consume some fruit, milk, candy and other foods before going swimming.

02Avoid swimming after strenuous exercise

Swimming immediately after strenuous exercise will increase the burden on the heart. During strenuous exercise, the body produces more heat, body temperature rises, and the sweat glands and subcutaneous blood vessels in the skin expand. If you suddenly jump into cold water, your body temperature will drop sharply, the subcutaneous blood vessels will contract sharply, and the sweat pores will be blocked, which can easily cause colds, acute joint pain and other diseases. In severe cases, it can lead to limb paralysis.

After strenuous exercise, you should rest for half an hour and wait for the sweat to subside before going swimming.

03Avoid swimming after drinking

Swimming after drinking alcohol will cause a large amount of glucose stored in the body to be consumed, resulting in hypoglycemia. Alcohol can interfere with the rhythm of excitation and inhibition of the cerebral cortex, making the mind dizzy and affecting the ability to judge the situation in the water. These factors undoubtedly increase the chances of swimming accidents.

Please treat swimming after drinking as equivalent to driving after drinking and take this as a warning.

04Avoid swimming after meals

Swimming with a full stomach after a meal not only affects the digestion and absorption of food by the gastrointestinal tract, but also easily causes stomach cramps, vomiting, abdominal pain and other phenomena.

After eating, you should rest for 30 minutes to an hour before going swimming.

05Avoid swimming during menstruation

During menstruation, women's body resistance decreases. If they go swimming, they will be stimulated by cold water, which can easily lead to irregular menstruation, excessive menstrual flow, prolonged menstruation and dysmenorrhea. The bacteria can also cause urinary and reproductive system infections.

06Avoid swimming in unfamiliar waters

When traveling in the summer, if you are not familiar with the surrounding environment and underwater conditions of natural waters, do not swim rashly to avoid accidents.

Remember not to swim in non-swimming areas.

07 Avoid eating immediately after swimming

It is advisable to rest for a while before eating after swimming, otherwise it will suddenly increase the burden on the gastrointestinal tract, which may easily cause gastrointestinal diseases over time.

After swimming, you can take a shower and rest before eating.

08 Avoid swimming without warm-up exercises

The water temperature is usually lower than body temperature, so you must do warm-up exercises before entering the water, otherwise you may feel uncomfortable.

09 Avoid swimming for too long

The duration of swimming should generally not exceed 1.5 to 2 hours, which is determined by the three reaction periods of the skin 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.

10. Don’t neglect hygiene after swimming

After swimming, germs can easily remain on the skin, and swimming pools are often disinfected with chlorine, which can easily irritate the skin.

After swimming, it is best to take a thorough bath with a shower gel containing nourishing ingredients.
