Why people with high blood pressure need to be careful of cardiovascular disease and stroke on hot days
People with high blood pressure , on hot days, blood pressure is often unstable. High temperatures cause increased sweating, the body easily loses water leading to reduced blood volume, the patient has low blood pressure.
Meanwhile, hot weather makes patients restless, difficult to fall asleep, makes the heart rate faster, leading to increased blood pressure at night.

In addition, in hot weather, people with high blood pressure tend to avoid exercise and often sit in cold rooms with the air conditioner turned on at low temperatures.
When entering and leaving an air-conditioned room with a sudden change in temperature from hot to cold, the dilated blood vessels will immediately contract, causing blood pressure to suddenly increase... This condition can cause the patient to experience dangerous complications such as stroke, cerebral infarction, cerebral hemorrhage, heart failure, myocardial infarction...
If unstable blood pressure persists, it can affect the eyes; kidney failure; atherosclerosis, blood clots, and embolism.
What should people with high blood pressure do to protect their health on hot days?
Limit going out in the sun
In hot weather, people taking blood pressure medication should not do much outdoor activity to prevent excessive vasodilation which can cause hypotension.
When you have to go out, especially during hot, sunny days, you should wear sunscreen, a hat, sunglasses, and bring water to drink regularly to replenish the water lost through sweating.

Do not turn on the air conditioner too low.
Such a sudden change in temperature from hot to cold will cause the blood vessels that are normally dilated to immediately contract, leading to high blood pressure. Conversely, if you are in an air-conditioned room for a while and then go out into hot weather, the blood vessels will dilate, which causes unstable blood pressure.
Drink enough water
Providing water regularly for the body is very important. People with high blood pressure should drink a lot of water and drink regularly, should not wait until thirsty to drink, to reduce blood viscosity, promote metabolism in the body and at the same time create the habit of drinking 1 glass of water after waking up in the morning and 1 glass of water before going to bed.
Eat healthy
Diet also plays an important role in controlling blood pressure. People with high blood pressure should supplement good foods such as: whole grains, fish, poultry, beans, vegetables, fresh fruits, milk and low-fat dairy products; eat foods rich in potassium such as tomatoes, sweet potatoes, grapes, beans; should eat fish, white meat such as chicken, skinless poultry; limit red meat such as beef, pork; limit cakes, soft drinks, foods high in fat.
Exercise regularly
When the weather is hot, even with little exercise, the body will sweat a lot, which makes many patients with high blood pressure, especially the elderly, often reluctant to exercise or walk. In fact, exercise will help blood vessels expand and contract well, increasing the durability of the vessel wall. Therefore, some people have compared exercise to "exercise for blood vessels".
Regular health check-up
The important principle to control blood pressure is that the patient needs to take medication regularly, without interruption. Therefore, people with high blood pressure need to be monitored regularly and have their accompanying diseases well controlled to avoid dangerous complications that affect their health.
