The principle of survival when entering the freezing zone

Hypothermia in cold weather is a dangerous complication, if not handled promptly, can cause cardiac arrest, death leading to death.

Due to the influence of cold air, the temperature of the North is low, in the high mountains of only 2-7 degrees Celsius. The high mountain areas in the North are more likely to appear frost, hoarfrost.

This is the strongest cold wave since the beginning of winter in the North. Many people in other regions want to experience this cold, so they make trips to the highlands, especially to wait for snow or ice. However, if you do not prepare health and medical knowledge for the trip, you may be in danger when faced with sudden cold air.

Hypothermia usually occurs when exposed to cold weather or cold water.

About this, Colonel - Doctor Pham Van Tien - Head of the 103 Hospital Emergency Department said that the cold, damaging cold weather combined with the humid rain, hoarfrost is one of the reasons why many people get sick. , mainly respiratory diseases, colds. The reason is because when breathing, the air is warmed by the nasal-throat mucosa, moistened and filtered a part before going into the trachea. When the weather is too cold, the nasal mucosa - the throat cannot warm enough for the air flow as it normally does, the inhaled air with low temperature causes the respiratory system to function poorly and cause nose-throat diseases. more severe is otitis media, bronchitis, pneumonia.

Dr. Tien notes that for people living in cold areas there may be mechanisms to regulate body temperature to adapt, but for those who do not have frequent cold exposure, many complications can occur. In particular, the most dangerous is the sudden hypothermia.

Carefully lower body temperature

"Normal body temperature is about 37 degrees Celsius. Hypothermia occurs when the body temperature falls below 35 degrees Celsius. This is a medical emergency that occurs when the body loses heat faster than creating Out, causing a dangerously low body temperature.

When the body temperature drops, the heart, nervous system and other organs cannot work correctly. If not treated promptly, hypothermia can stop cardiac activity and respiratory system leading to death, " Dr. Tien said.

Hypothermia usually occurs when exposed to cold weather or cold water . In particular, the elderly, young children, babies, thin people are high-risk subjects. In addition, people who use alcohol and go out in cold weather are also able to lower body temperature. Dr. Tien noted that this is very likely to happen because many people mistakenly think that when it's cold, drink alcohol to warm up the body.

"Alcohol can make the body feel warm, but it causes dilated blood vessels or enlarges, resulting in faster heat loss from the surface of the skin," the doctor recommends.

Hypothermia is very common when exposed to very cold weather, when people have not yet adapted.

People with hypothermia often have tremors, clumsiness, lack of coordination, slurred speech, fatigue, lethargy, confusion or memory loss, difficulty speaking, trembling, cold people, loss of coordination, breathing. Unusually slow, the victim may fall into a coma. People with hypothermia need urgent care and need to be hospitalized to avoid bad complications.

In particular, people with hypothermia are often unaware of their condition, because symptoms often start slowly, unpredictably.

In the same view, Dr. Phan Xuan Trung - Medic Medical Center also said that hypothermia is very common when exposed to cold weather, when people have not yet adapted . Many people only take precautions, but in fact, hypothermia is more dangerous by us or subjective while it has very serious complications, especially without the available medication for patients to "pull" the heat. degree up.

When a person has hypothermia, while waiting for an emergency, it is necessary to let the patient lie in a warm, windy place, remove wet clothes, not use hot water, a heater, or a heating lamp to warm the victim. Should warm from the center of the body. In it, need to protect the most important central part is the chest area (lungs). This is the body part exchanged with the outside air.

And Dr. Tien noted, in cold weather, the principle is to keep the body warm with careful clothes, towels and hats. In addition, it can warm the body with fresh ginger juice, rub oil and eat hot items. The lowest limit is getting out . Particularly, it is best to watch ice, snow, not for the elderly and children to accompany.
