What is heat stroke? | Preventing Summer before it happened
What is heat stroke? -In a hot environment, we feel thirsty, sweating, tiredness, etc. This is quite normal, but if you ignore these minor physical discomforts or improperly handle them, you may get heat stroke, and even severe can be fatal. Why is it “heat stroke“?

High Temperature and Humidity Join Forces

Our body generates a lot of heat during metabolism, and this heat must be dissipated through different ways (such as perspiration) to maintain body temperature in the proper range.
Under normal circumstances, the hypothalamic body temperature regulation center can balance the body’s heat production and heat dissipation base energy, but when the surrounding ambient temperature rises to a certain extent, and the humidity is high and the ventilation is poor, the body evaporates. The heat dissipation process is blocked, and a large amount of heat is accumulated in the body, and heat stroke may occur at this time.

Is sweating like a heatstroke?

When we perform activities that require a lot of physical exertion in a hot environment, there is always the possibility of heat stroke.

Especially when working or exercising under the scorching sun or in a high-temperature environment, the body’s ability to regulate body temperature cannot be adapted, and the heat energy generated in the body cannot be properly radiated outward.

Accumulation of the body and high fever can cause heat stroke. The initial signs include headache, dizziness, palpitations, nausea, etc., then stop sweating, body temperature rises, if not rescued in time can cause coma and die.


Heat Stroke Symptoms

Our bodies normally generate heat as a result of metabolism and is typically able to dissipate the heat by radiation of heat through the skin or by evaporation of sweat.

However, in extreme heat, high humidity, or vigorous physical exertion under the sun, the body may not be able to dissipate the heat and the body temperature rises, sometimes up to 106 F (41.1 C) or higher. Yet another cause of heat stroke symptoms is dehydration.

A dehydrated person may not be able to sweat quick enough to dissipate heat, which causes the body temperature to rise.

Heat stroke symptoms is also often referred to as heatstroke or sunstroke. Severe hyperthermia is defined as a body temperature of 104 F (40 C) or higher. Heat stroke can kill or cause damage to the brain and other internal organs. Even though stroke symptoms mostly affects people over age 50, Heat Stroke Symptoms also takes a toll on healthy young men or women.

Heat Stroke Symptoms and signs

  • Throbbing headache
  • Dizziness and light-headedness
  • Lack of sweating despite the heat
  • Red, hot, and dry skin
  • Muscle weakness or cramps
  • Nausea and vomiting
  • Rapid heartbeat, which may be either strong or weak
  • Rapid, shallow breathing
  • Behavioral changes such as confusion, disorientation, or staggering
  • Seizures
  • Unconsciousness

Infirm, obesity should pay more attention

to external factors such as hot weather, humid and poor ventilation, physiological factors also affect the possibility of heat stroke; so weak constitution, obesity, chronic diseases, children, the elderly, pregnant women, etc.

Heatstroke is more likely to occur, and hunger, lack of sleep, excessive fatigue, and taking certain drugs can also induce heat stroke.

However, the excessive consumption of physical strength at high temperatures is the main cause of heatstroke.

This is why some people who are physically fit on a regular basis (such as police officers or firefighters who often practice physical fitness) will also consume physical strength such as walking or running in the hot sun. When you exercise, you will not have the reason for heat stroke.

Preventing “Summer” before it happened

The best way to prevent heat stroke is to strengthen protection, avoid direct sunlight, and reduce the amount of time and exercise during the hot sun or high-temperature environment. Replenishing water at any time and drinking more heatstroke and cooling drinks on weekdays can reduce the chance of heatstroke.
Heatstroke prevention ten tips

·         Keep it in a cool and ventilated place or use an electric fan or air conditioning system to avoid excessive room temperature.

·         Keep an eye on the weather before going out to bring proper equipment

·         For outings, don’t choose the most intense time between 11am and 2pm and start exercising before 8am or after 6pm.

·         Avoid strenuous activities in hot weather. If it is unavoidable, wear thin, light, loose and airy clothes. When you are outdoors, wear a wide-brimmed hat to avoid exposure.

·         In the outdoor activities, you can always have a refreshing drink. In addition to boiling water, juice, light saltwater, and sports drinks, you can also use green bean boiled water instead of boiling water for daily drinking, or drink lemonade or sour plum tea (sweet plum water and rock sugar for cold drinking) Drinks that quench your thirst and increase saliva secretion can alleviate the effects of heat.

·         Drinks containing caffeine, alcohol, too sweet or too cold should be avoided as they can cause paralysis in the stomach. The daily diet should be as light as possible. It is not advisable to eat too much fried or greasy food or excessively strong food, otherwise, it will increase the burden on the stomach.

·         Avoid being exposed to high temperatures or sun exposure when you are hungry, lack of sleep, or getting sick.

·         Certain drugs, such as colds and colds, may affect the body’s perspiration function, so pay special attention to heatstroke prevention during medication.

·         Do not leave in the car compartment that is sealed and parked, otherwise there may be oxygen deficiency or even suffocation.

·         When swimming in an outdoor pool or beach, or when playing outdoors, apply sun oil with a sun protection factor of 15 or higher.
