Hot and sweaty in dog days is a high incidence period of cardiovascular and cerebrovascular diseases. This "heart care" guide should be kept away.

Dog days are not only hot, but also bring opportunities to some diseases. I would like to remind you that dog days are also a period of high incidence of cardiovascular and cerebrovascular diseases. We should not only pay attention to heatstroke prevention and cooling, but also pay attention to heart health care.

In hot summer, especially in dog days, cardiovascular and cerebrovascular diseases increase obviously. This is because the temperature is too high in dog days, the humidity increases, and the blood vessels on the body surface dilate, while the blood supply to the cardiovascular and cerebrovascular systems decreases, the metabolism accelerates, and the oxygen consumption of the heart and brain increases. Due to neuroendocrine disorder, sleep quality declines, which will lead to increased blood pressure fluctuation, excessive sweating, lack of water and electrolyte, and increased blood viscosity, which is easy to induce arrhythmia. Therefore, dog days are also a high incidence of cardiovascular and cerebrovascular diseases.

What risk factors should we pay attention to? The inducing factors of cardiovascular and cerebrovascular diseases in dog days include fatigue, staying up late, dehydration, smoking and drinking, sedentary, gluttony and other unhealthy lifestyles. People with hypertension, diabetes and family history should pay more attention. Special attention should be paid to myocardial infarction caused by summer cold. Every summer, clinical patients will encounter myocardial infarction when they stay up all night watching football and drinking cold beer. Entering the air-conditioned room from the hot outdoor, the temperature drops sharply, or drinking a lot of cold drinks directly stimulates the sudden contraction of blood vessels. The strong contraction of hot and cold blood vessels will lead to the rupture of plaques formed in coronary arteries, causing thrombosis, blocking blood vessels and sudden myocardial infarction.

In dog days, people with the above risk factors should pay attention to some details in their lives. The following "heart care guide" must be read carefully.

1. If you sweat for a long time in summer, take the initiative to drink warm water and replenish electrolytes in time. You can also drink some light salt water or functional drinks to supplement the lost potassium and sodium. In addition, eat more foods containing potassium, such as fresh vegetables and fruits, to keep the balance of sodium and potassium. Have a light diet and reduce greasy food.

2. Exercise properly and avoid sedentary. Sit for an hour and stand for ten minutes while studying. Need to exercise, reduce moderate and high-intensity physical labor, avoid going to places with high temperature and high humidity, avoid morning exercises, and pay attention to sun protection when going out.

3. Avoid excessive temperature difference. Operators should pay attention to heatstroke prevention and cooling in high temperature environment to avoid heatstroke. Keep the environment as unchanged as possible. Don't turn the air conditioner down too low. Sweating slightly during physical activity. You can add a thin coat to the air conditioner. Don't take a cold bath immediately after the activity. Dry your sweat with a dry towel, have a rest, and then rinse with warm water. Avoid drinking too many cold drinks. Drinking too many cold drinks at a time will not only increase the burden on the heart and digestive tract, but also easily induce thrombosis.

4. Ensure sleep, keep a peaceful mind, live a regular life, combine work and rest, keep the stool unobstructed, avoid overwork, live a regular life, and ensure adequate sleep. Avoid mental stress and excitement.

5. Patients with cardiovascular diseases should pay special attention to quitting smoking and drinking, often monitor blood pressure, blood sugar and blood lipid, control the three highs, take medicine regularly, and don't stop taking medicine without authorization. Under the guidance of the doctor, adjust the plan according to the individual situation. # A healthy summer #

6. If you have chest pain, chest tightness, headache, dizziness, palpitation, transient syncope and other symptoms, don't explain them with reasons such as poor sleep or overwork, and go to a regular hospital in time. # Dr. Doka Super Team #
