From today onwards, it will officially enter the ambush, as if to celebrate the arrival of the sweltering heat, and the temperature of these two days is also high for one day and one day. In order to escape the heat, people have tried all kinds of ways: those who stay in the air-conditioned room and do not come out, those who eat a few popsicles one day and drink ice water, those who take cold showers...
There are many ways, here we should remind everyone: to relieve the heat, summer must choose a scientific and correct way, so as not to cause other health problems.
Cases of myocardial infarction and sudden death caused by incorrect summer heat avoidance every summer are not uncommon, and only by understanding its importance can we prevent it.
In hot weather, there are 4 things to avoid
01 Long time blow air conditioning
Blowing air conditioning is a simple and effective way to escape the heat in summer. Many people blow air conditioners when they go to work, and turn them on again as soon as they go home. Although it feels comfortable, it may also bring some health risks.
Beware of "hot strokes"
When turning on the air conditioner, if the temperature difference between the inside and outside of the room is too large, people will feel sudden cold and hot when frequently entering and leaving the room, which is more likely to cause the balance adjustment system in the body to be dysfunctional, resulting in headaches, colds and other symptoms.
For middle-aged and elderly people, especially patients with hypertension or arteriosclerosis, suddenly entering the low-temperature living room is more likely to cause blood vessel contraction due to cold stimulation, resulting in impaired blood circulation in the brain and "hot stroke".
Be wary of bacterial transmission
Air-conditioned rooms tend to be dry and at the right temperature, making them easier for germs and viruses to survive. In addition, when the air conditioner is turned on for a long time, because the doors and windows of the room are closed, the air does not circulate, and the bacteria are more likely to spread, resulting in infection.
Of all the bacteria, a bacterium called Legionella is the most dangerous and common. This bacterium is often hidden in the air conditioning refrigeration device, and with the cold wind out of the floating in the air, after being inhaled by the human body will appear upper respiratory tract infection and fever symptoms, severe cases can lead to respiratory failure and kidney failure.
❆ Turn on the air conditioner correctly, it is recommended to do this:
(1) The temperature is controlled at 26 °C. 26 °C is the most comfortable temperature for the human body, and can ensure that the indoor and outdoor temperature difference is small, reducing the burden of the body temperature regulation center.
(2) The air conditioner wind blows upwards. Cold air will sink, so the wind blowing upwards can not only cool down, but also avoid headaches, dizziness and other problems caused by the cold wind blowing directly on the body.
(3) Pay attention to ventilation. Turning on the air conditioner for a long time will make the air dryer, and at the same time, due to the closed environment, the air does not circulate, and it is more prone to respiratory diseases. Therefore, it is recommended to open the window every 1 hour for 15 minutes to breathe, and go outside to walk around and breathe fresh air.
02 Gluttonous cold drinks
It is very common to eat a cold drink in the scorching sun, but if you eat it wrong, it can easily lead to a "fatal crisis".
As early as 1996, in the journal "Emergency Medicine", there were cases of "acute myocardial infarction due to eating 100 grams of frozen watermelon", and in recent years, the media has also reported a number of cases of myocardial infarction caused by eating cold drinks.
One thing these cases have in common is a short, high intake of frozen beverages or foods. Summer heat, the amount of sweating in the human body increases, if the water supplement is not timely, the body itself is prone to symptoms of lack of water, blood concentration rises.
At this time, if you eat a large amount of cold drinks in a short period of time due to greed, it is very easy to cause vasoconstriction and spasm, thus inducing myocardial infarction. Therefore, when eating cold drinks to avoid the heat, we must pay attention to the amount of consumption, and pay attention to eating slowly.
03 Pour water
Due to the increase in sweating in the summer, the loss of water in the body makes people feel more thirsty, and the amount of water consumed will increase accordingly. However, be careful not to drink a large amount of water at one time, so as not to cause accidents.
When sweating profusely, salt is excreted along with sweat. At this time, if you continue to drink water and do not replenish salt, the salt in the blood will continue to decrease, the plasma osmotic pressure will decrease, and then hypotonic dehydration will occur, so that the cells will be edematous, and people will also have dizziness, dizziness and other "water poisoning" symptoms.
04 Take a cold shower
Similar to the situation mentioned above, taking a cold bath in a hot temperature is also easy to cause vasoconstriction and spasm.
Especially for people who have their own blood clots, cold stimulation caused by cold bathing on the whole body may also lead to severe spasms of coronary arteries, resulting in plaque rupture, the formation of blood clots, and myocardial infarction.
It is best to take a warm bath in summer. It is not only conducive to cooling down and preventing diseases, but also helps to speed up blood circulation, reduce muscle tone, eliminate fatigue, improve sleep, and enhance disease resistance. If there are really no conditions, you can only take a cold shower, but also keep the following precautions in mind:
First of all, women, patients with coronary heart disease, joint pain patients, and people with skin allergies are not recommended to take cold baths to avoid other health risks.
In addition, in the case of sweating a lot after exercise, do not take a cold shower directly. Wait until the body has cooled down naturally, first wet the hands and feet, then soak the towel to wipe the front chest and back, and finally wet the whole body with cold water. Pay attention to drying the skin in time after washing.
There are so many summer misunderstandings, so what should be done to easily survive this hot summer?
