Preventing diseases during hot and sunny days

This heat wave, in many localities, the temperature of outdoor heat absorption is up to 45 degrees C. With high heat, the adaptation of the body is very difficult, so it is easy to get sick. So how to deal with hot weather to protect health?

Preventing dehydration for the body by drinking enough water, eating thin food will be a useful measure of health promotion to cope with hot sun.

The most vulnerable are the elderly and children

These hot days, whether sitting in a house with a fan or walking on the street, many people still sweat. The amount of sweat escaping much is the amount of water excreted from the body. According to BS MA Le Thi Hai, Director of the examination center - nutrition consultant, Institute of National Palace, the more sweat out, the more easily the body becomes dehydrated. At that time, the body will be tired, dizzy, easy to cause fever, in many cases of severe dehydration when going out in the sun makes patients susceptible to sunstroke, causing headaches, difficulty breathing .

According to Dr. Nguyen Trung Anh, Institute of Geriatric Medicine, the current hot weather is very disadvantageous for the elderly, especially those with chronic diseases (cardiovascular, blood pressure .). When the temperature rises, it is difficult for the elderly to keep up because the ' heat control center' is no longer as sensitive as it was in the youth, leading to inadequate temperature regulation. At the same time, the ' thirsty alert center ' in the elderly is also poorly functioning, so the body lacks water but does not feel thirsty, does not promptly replenish the body's water. Since then, it is easy to lead to heatstroke, getting sick or getting worse in days when the temperature rises. Therefore, children always remember to remind the drinkers, give them soft foods, thin, plenty of water such as porridge, vermicelli . The addition of enough water will help you to be healthy and alert. , more lively.

As for children, many people think that because they drink a lot of milk, eat porridge and fruit juice, they rarely remember to give them water, but children often only have a little water to drink after eating milk, eating porridge . In fact, the water demand in children is very high. For preschool children aged 3-5 years, at least 1,000ml of water and 500ml of milk / day should be given; Primary school age is 1,500 ml of water / day. Note that children should not drink carbonated soft drinks, industrially processed water has many sugar, making them more and more uneasy. Should the children drink mainly fresh fruit juice, vegetable juice, filtered water . With this view, Associate Prof. Dr. Nguyen Tien Dung, Head of Pediatrics, Bach Mai Hospital said: " Dehydration is the cause of fever. Because children have not developed their bodies properly, their ability to heat is poor, so they have severe weather conditions, many dehydrated children are more prone to fever than adults ".

Anti-dehydration for the body

Anti-dehydration for the body must always start with drinking lots of water, especially when there is a lot of sweat. According to Dr. Hai, with normal people, the amount of water is taken into the body about 2500ml / day, in which drinking water is about 1,000-1,500 ml. Waste water is also about 2,500ml including: 1,000-1,500ml urine, evaporation through skin 250-600 ml . Depending on the season, the nature of labor, the diseases that water is put into or discharged different changes.

Another note to keep in mind to prevent dehydration during the summer day, always carry with you with your water, constantly drink little by little rather than letting you drink . As those who have to travel a long way, go for hours on motorbikes, if they come to a new place to drink water, then at this time, the body has lost a lot of water, feels very tired, has all the water at that time. Not even right. The best way is to bring a bottle of water with you, when you see a lot of sweat, stop 'taking' a sip of water and continue. The scattered addition is much better than the thirst for drinking at a time.

When water from the body evaporates through the skin due to sweating, it is not just filtered water as we drink it, but it includes salt, minerals, sugar . That's why when you lose a lot of water, just drink water no body does not recover easily. Therefore, after going back to the sun, if you see too much sweat, the tired one is best to mix oresol with cool boiled water in the right proportion to drink. Or as in rural areas, when people go to work to become tired, often drinking fresh lemon juice with a pinch of salt also helps the body to recover quickly .

In a cool place, shield when going out

This heat wave, when it was 8:00 am, the weather became very fierce, when going out on the street, smoke, dust, the heat from the steaming road made it even more frustrating. Therefore, try to take your child to school, go to work 8 hours and pick him up when the afternoon sun has subsided. In hot weather, it is best to stay in the room, use air conditioning or fan, wear loose clothes, sweat-absorbent. If you are forced to go out in the sun, remember to have a thick face mask, a tight cloth and a sunscreen that will help prevent the glare of the sun.

According to Assoc.Prof.Dr Dung, hot sun like this, going out in the rush hour is very likely to occur heatstroke due to being too long exposed to sunlight or at high temperatures. Sunstroke may be accompanied by central injury due to direct effects of ultraviolet rays from the sun on the head, nape . if not timely emergency will die very quickly. The reason is that the outside temperature is higher than 40 degrees Celsius, while the body temperature is 37 degrees Celsius. To stabilize the body, the heat must be exhausted outside, but higher outside temperatures interfere.

In these days, people also need to pay attention to the sudden temperature difference. For example, just go in the sun and don't go right into the air-conditioned room , but open the room, stand for about 1 minute for the heat to sink in the person who gradually adapted to the coolness inside and then enter the room. The room temperature should be adjusted at 25-28 degrees Celsius and in the room should have a ventilation fan to ensure the environment in the room is ventilated, avoid too tight room, feel cool air but can store bacteria , viruses cause disease.
