Danger of heat shock

The elderly and children are the two subjects most likely to experience health problems when the weather becomes uncomfortable.

Note children and elders

Doctor (BS), specialist II Truong Quang Anh Vu said that children, the elderly, people with cardiovascular diseases (high blood pressure, myocardial anemia …) or endocrine diseases (hyperemia, etc.) should be paid attention to. thyroid, diabetes …) may be more susceptible to heatstroke and more severe than young, healthy people.

“Long exposure to the sun, especially when you have to work hard, and exercise strenuously, can cause the body temperature to suddenly rise due to a disturbance in the central body temperature, along with the vasodilation phenomenon, the body loses water through sweat, which leads to a series of symptoms of “heatstroke”, mild, can increase heart rate, shortness of breath, palpitations, palpitations; more severe dizziness, dizziness, headache , difficulty breathing, cramps, limbs exhausted … “- Dr. Vu explained.

Dr. Truong Quang Anh Vu also affirmed that the risk of sudden death from heat shock is real, if there are the above symptoms of heatstroke but not handled properly. When you see mild sunstroke, you must go to a cool place to rest immediately, drink water, wash your face to cool; If you feel tired a lot, you must go to the nearest medical facility. Absolutely not try to continue because the condition may aggravate. “The most serious consequences are fainting, coma, heart failure leading to death” – Dr. Vu warned.

As a precaution, when going to the street, especially children and the elderly, you should prepare sun protection equipment such as hats, sunglasses, long-sleeved shirts with cool materials and bring drinking water because dehydration also causes the situation. Heat shock is more likely to occur. At noon, if there is nothing so necessary, it should be limited to the street.

Hot weather is also often associated with a high UV index. According to the World Health Organization (WHO), most illness and death related to ultraviolet rays (UV rays) can be avoided through simple preventive measures. The Global Burden of Disease report estimates up to 60,000 deaths a year worldwide from excessive UV radiation exposure (48,000 melanoma cases and 12,000 skin cancers).

Overexposure to UV rays is also a risk factor for eye diseases, especially cataracts, affecting the functioning of the immune system. Safety measures such as limiting going out in the midday sun, wearing sunscreen including hats and sunglasses should be applied when the UV index is 3 or above.

Need to “cool” properly

Dr. Truong Huu Khanh, Head of Department of Infection – Neurology BV for Children 1 (Ho Chi Minh City), said that in the hot season, children are more susceptible to illness than the cold season, this is also favorable weather for some seasonal diseases. Viral fever is still the most common, including illnesses such as hand, foot and mouth disease, chickenpox, mumps, and typhus fever; In addition, it is necessary to prevent diarrhea (due to food spoiling easily) or respiratory inflammation (due to activities).

The heat also makes many children lose their appetite. To overcome this, the children eat foods with water and cool mouth; can divide the menu of the day into several meals, a little thin food; Older children cook more soup, have green vegetables and fruits; while the child is still suckling, it is divided into many breastfeeds.

If you take young children to swim, go to the beach in the summer to “cool down”, it is also important to pay attention to the time, choose a time that is neither too cold nor too hot, and it is cool between 16 and 17 hours. Children’s swimsuits should be swimsuits like imitators. Bath for no more than 30-40 minutes, bath for 15-20 minutes is to dry, rest for 10-15 minutes, then shower for 15-20 minutes.

When you stay at home, you should not let your baby bathe too long, do not bathe many times, do not soak, do not bathe more than 18 hours late, if it is too hot at night, you should just wipe yourself cool so that the baby can sleep.

Incorrect bathing is one of the reasons why children are prone to colds this season, not to mention an increased risk of viral diseases because when infected with a cold, the resistance decreases. In addition, make sure the bedroom is cool, air-conditioned to 27 degrees C is best, if you use a fan, you should not fan directly on the baby. When going from outside to the air-conditioned room, keep warm for the first time to avoid sudden temperature changes.

Hot, ultraviolet rays at the same time impact in HCMC

Mr. Le Dinh Quyet, Deputy Head of Forecast Department of Hydrometeorology Station of the Southern region, said: “Although unseasonal rain has appeared, however, HCMC is still hot from morning to night”.

Accordingly, the weather in the city during this period always has a high temperature range. From 7 o’clock to more than 17 o’clock, almost everyone on the street feels the hot heat very uncomfortable. The reason is that the subtropical high pressure elevates the axis to the North and has a strong operating axis through the North Central. The highest temperature in hot spots will range from 35-36 degrees Celsius, some places over 36 degrees C. The time with a temperature of over 35 degrees C appears from 11 hours to 15 hours.

About ultraviolet rays, in the next 3 days (from March 27), the UV index is always high, causing harm to the body. From 11:00 to 14:00, the UV index of the day reaches a very high threshold of harm (9-11, below 5 is safe).
