Sunstroke in the middle of the cold season
According to specialist doctor II Truong Quang Anh Vu, Head of General Planning Department of Thong Nhat Hospital (Ho Chi Minh City), the phenomenon of “heatstroke” can still occur in cool seasons, especially in the South, where the afternoon is still quite hot. The cause of heatstroke is not only hot heat, intense sunlight but also a combination of factors such as vigorous movement, long sun exposure time, dehydration, background disease …
“The first thing to do is whether the season is hot or cold, you should bring water when you have to go out for a long time, especially the elderly, already have blood pressure, diabetes … Bring water when thirst is supplemented. The next step is to avoid staying in the sun for a long time, especially in the midday sun even though the temperature is not too hot that day. If you have all three problems “hot weather – extreme exercise – dehydration” usually the body will react Two directions: One is the increase in body temperature, which increases body temperature, stimulates the heart to beat fast, increases blood pressure Second, the body tries to fight this by dilating the vessels, increasing sweat secretion to decrease body temperature. This again aggravates dehydration, reducing circulating volume, causing a drop in blood pressure … “- Dr. Anh Vu explained.
In addition, high blood pressure itself is a group of diseases that are easy to “turn over” when the season changes because the body has not yet adapted to the change.
The group of gastrointestinal diseases also often increases with changing weather, including digestive disorders due to spoiled food due to no change in storage, but mainly encountered during heat waves. After gastrointestinal disturbances are often stomach pain, the cause is due to the reaction of the sympathetic nervous system to the changes of weather, especially when it turns cold, which affects more or less the psychology of people. sensitive. People suffering from neuropathic upset stomach should also treat peptic ulcers at the same time and try to reduce stress. You can see a psychologist if the problem is out of your control.
