It is helpful to prevent heat exhaustion if you carry a folding fan (hapjukseon) that can be easily folded and unfolded and fanned from time to time. [사진= 게티이미지뱅크]Heat exhaustion (heat exhaustion) often occurs when you sweat a lot in hot sunlight and in a high temperature and high humidity environment, but do not replenish water well, or drink only bottled water with low salt while continuing to sweat. Gradually, fatigue, loss of energy, dizziness, headache, vomiting, muscle spasms, etc. appear. Usually, the upper body and head are hot, but the neck is cool, and sweat continues to come out even when exposed to a fan or air conditioner.
The basic rule when heat exhaustion sets in is to move to a cool place, take off your clothes, and lower your body temperature with water and wind. It is safe for the elderly and people with underlying diseases such as high blood pressure, diabetes, and heart disease to go to the hospital. Vomiting symptoms do not appear, consciousness is reasonably clear, tachycardia or arrhythmia, and severe fever is not present.
When taking a lukewarm shower or washing your face with cold water is difficult, folding a fan or newspaper to create wind is quite effective in relieving heat exhaustion. It is helpful to prevent heat exhaustion if you carry a folding fan (hapjukseon) that can be easily folded and unfolded and fanned from time to time.
Dasan Jeong Yak-yong described the fan as saying, “It has the power to move, but since it is folded, it quietly holds the wind.” One of the Confucian scriptures, ≪Poetry, Poetry and Poetry≫, a commentary, ≪Poetry and Poetry,≫ has a passage that says, “Paper and bamboo combine to create a clear wind.” Folding fan means ‘bending by hand to create wind’. Folding fan is an invention of the Goryeo Dynasty and is said to have been exported to China (Song Dynasty). As it blocks UV rays and creates wind, it is a very useful health product for preventing heat exhaustion.
According to Dongwha Pharm and the Gasong Foundation, in the old days when cooling technology was not developed and summer was a big challenge, fans were very popular as gifts given and received around Danot Day (May 5 in the lunar calendar, June 22 this year). gathered This fan, also called Danohseon (端午扇) and Jeolseon (節扇), was exchanged between people facing the beginning of the harsh summer as a way to ‘endure the heat safely’. During the Joseon Dynasty, the king bestowed fans out of a sense of caring for his servants who worked hard in the hot summer.
In a healthy person, the body temperature defense function works normally in a heat wave or a tropical night, but in the case of the elderly, the body temperature center’s defense function declines, and the body faces a limit in coping with itself. Moreover, patients with chronic diseases such as hypertension, heart disease, diabetes, and hyperlipidemia are more at risk. Even if you overwork, drink too much, or do not sleep properly, your body temperature control and defense functions do not work properly.
Even healthy people can lose control of the body temperature center if they continue to suffer from the heat. When the human body feels the heat, blood vessels contract and relax actively to maintain an appropriate body temperature. Not only heart disease, but also high blood pressure and diabetes patients should be especially careful regarding acute arrhythmias, angina pectoris, and stroke.
