Spending a long time in the water can cause headaches

It is hot in summer. In order to avoid the heat, many people swim and they love swimming very much. But sometimes after swimming, the body shows various symptoms. Well, next I will talk about what to do if you have a headache after swimming.

What to do if you have a headache after swimming

1. If the headache is caused by low water temperature.

You can reduce the time you spend exercising in cold water, warm up thoroughly before entering the water, and adapt to the water temperature first.

2. Avoid going ashore immediately after high-intensity swimming.

Swim slowly in the water to give your body time to adapt.

3. Of course, the headache after swimming will generally disappear within 2-3 days.

If the situation is serious, it is recommended to go to the hospital for treatment.

Causes of headache after swimming

1. Headache after swimming or caused by insufficient blood supply to the brain after muscle relaxation.

Although more blood is diverted to the limbs when swimming, the muscles continue to contract and the blood flows faster, so the brain will not suffer from ischemia. After swimming, the muscles relax, the capillaries expand, and the amount of blood stagnant in the muscles of the limbs increases, resulting in a relatively insufficient blood supply to the brain. In addition, when you just get ashore, your body suddenly changes from a horizontal state to an upright state, and the sudden change in body position will also aggravate the lack of blood supply to the brain.

2. Headache after swimming or caused by long-term cold stimulation.

When swimming in low water temperature or swimming for a long time, the prolonged stimulation of cold water can also cause the capillaries in the head to contract, creating a feeling that the head is being tightly clamped.

3. Headache after swimming or caused by excessive nervous tension during swimming.

Or if your swimming skills are not very good and your nerves are tense, the neck muscles will continue to contract, causing the blood vessels in the head to dilate, which may also lead to headaches, dizziness, etc.

4. Headache after swimming or caused by choking on water while swimming.

Headache, buzzing in the ears, or dry heaving and nausea are mostly caused by water in the ears or in the nose.

5. Headache after swimming may be caused by hypoglycemia.

Dizziness and headache are often caused by swimming for too long, which consumes too much energy in the body, leading to low blood sugar, coupled with physical fatigue and hunger.

6. Headache after swimming or catching a cold after swimming.

For example, if the swimming pool water temperature is too low, the swimming time is too long, or if you take a shower immediately after swimming and do not change clothes in time, these may cause a cold, which may lead to headaches, dizziness, and even vomiting.

Precautions for swimming safety in summer

1. Avoid swimming before or after meals.

Swimming on an empty stomach will affect appetite and digestion function, and may also cause unexpected situations such as dizziness and fatigue during swimming; swimming on a full stomach will also affect digestion 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 the resistance and cause colds, pharyngitis, etc.

3. Avoid swimming during menstruation.

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

4. Avoid swimming in unfamiliar waters.

When swimming in natural waters, avoid entering the water rashly. It is not advisable to swim in waters where the conditions around and under the water are complicated to avoid accidents.

5. Avoid prolonged exposure to the sun and swimming.

Prolonged exposure to the sun can cause sun spots or acute dermatitis, also known as sunburn. To prevent sunburn, it is best to use an umbrella to shade yourself after going ashore, or rest in the shade of a tree, or use a bath towel to protect your skin, or apply sunscreen to exposed areas of your body.

6. Avoid swimming without doing 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.

7. 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.

8. Avoid swimming for too long.

The skin generally has three reaction phases 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.
