1. 1, hypoglycemia
The early symptoms of hypoglycemia are palpitation, fatigue, hunger, shaking hands, cold sweat, pallor, chills in limbs, or nausea and vomiting, which are mainly caused by excessive excitement of sympathetic nerves and adrenaline. Hypoglycemia is paroxysmal, not recurrent, and there are fewer symptoms of chest tightness and shortness of breath.
1.2, anemia
Anemia can cause dizziness, palpitation, tachycardia and other symptoms, but generally does not cause chest tightness.
1.3, hypotension
It also mainly causes dizziness, but the blood pressure is about 60/90, which generally does not cause changes in blood supply.
It is best not to swim in these periods.
2. 1, avoid swimming before and after meals: swimming on an empty stomach will affect appetite and digestive function, and there will be accidents such as dizziness and fatigue during swimming; Swimming with a full stomach will also affect the digestive function, and it will also cause stomach cramps and even vomiting and abdominal pain.
2.2. Avoid swimming after strenuous exercise: swimming immediately after strenuous exercise will increase the burden on the heart; A sudden drop in body temperature will weaken resistance and cause colds, pharyngitis and so on.
2.3, avoid swimming during menstruation: swimming during menstruation, germs easily enter the uterus, fallopian tubes and other places, causing infection, leading to irregular menstruation, menorrhagia and prolonged menstruation.
Generally speaking, skin has three reaction periods to cold stimulation.
The first stage: after entering the water, stimulated by cold, the skin blood vessels contract and the skin color is pale. The second stage: after staying in the water for a certain period of time, the blood flow on the body surface expands, the skin turns from pale to reddish, and the skin turns from cold to warm. The third stage: the stay time is too long, the heat dissipation of body temperature is greater than fever, and the skin has goose bumps and chills. This is a taboo period for summer outing, so leave the water in time. Generally speaking, the swimming time should not exceed 1.52 hours.
Precautions for swimming
1, get ready for exercise.
When swimming, you need to do enough warm-up activities before entering the water, which can improve the excitement of the nervous system, make the motor organs enter the state of motion, speed up the blood flow and improve the level of substance metabolism accordingly. This can not only promote the body to play better sports ability, but also prevent dizziness, palpitation, shortness of breath, abdominal pain and other phenomena after entering the water. At the same time, necessary warm-up activities can also increase the stretching of muscle ligaments and the range of joint activities, which can effectively prevent cramps and joint injuries.
Don't eat 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 will easily lead to gastrointestinal diseases after a long time.
Don't forget to brush your teeth and gargle after swimming.
When people swim, the pool water often enters the mouth, and some germs follow. If you don't clean your mouth in time before eating after swimming, these germs will enter the gastrointestinal tract, and children with poor resistance are more likely to become victims.
Asthma and palpitation after exercise may be heart failure.
Heart failure is caused by many reasons, such as decreased myocardial contractility, inability to effectively pump blood out of the heart to meet the needs of metabolism, insufficient blood perfusion in organs and tissues, congestion and dysfunction of various organs in the lungs and the whole body. This is heart failure. Heart failure can be divided into left heart failure, right heart failure and heart failure. The common manifestations of left heart failure are palpitation and asthma after exercise. Normal people will not feel flustered and breathless when walking 4 ~ 5 flights of stairs, but patients with left heart failure will not. After walking a few flights of stairs, I felt seriously flustered and out of breath, and my heart seemed to jump out of my throat. Even after resting for 20 to 30 minutes, I still feel short of breath, have difficulty breathing, and even my heart is beating faster and faster. Asthma is when a person whose condition is aggravated goes flat. What is it called medically? Fatigue, difficulty breathing? . Some patients with heart failure will suddenly wake up when they sleep at night, feeling that they are not breathing enough and have difficulty breathing. They need to sit up and catch their breath immediately, so that they will get better gradually. Patients with right heart failure mainly show systemic congestion. The most typical symptom is edema, which usually occurs in drooping parts.
