Temperatures in Thailand have been rising to alarming levels, as high as 41.5°C in certain areas in Thailand. In districts such as Bang Na in Bangkok, "feels like" temperature has soared up to 50°C, leading to health authorities issuing an official health alert warning. The meteorological department of Thailand has also forecasted an elongated summer, with scorching temperatures lasting until at least mid-May. Thus, the risks of heatstroke should not be taken lightly.

What is heatstroke?

Heatstroke is a serious medical condition that occurs when the body's temperature regulation mechanisms fail and the body temperature rises to dangerous levels.  The body normally cools itself by sweating, but in extreme heat, sweating may not be enough, and the body may start to absorb more heat than it can dissipate. This can lead to a rapid increase in body temperature, which can cause damage to the brain, heart, kidneys, and other organs; and can be fatal if not treated promptly. 


What are the symptoms of heatstroke?

The symptoms of heatstroke can vary from person to person, but some common signs include:

  • High body temperature (above 103°F or 39.4°C)
  • Hot, dry skin
  • Rapid pulse
  • Rapid breathing
  • Headache
  • Nausea and vomiting
  • Dizziness or confusion
  • Seizures
  • Loss of consciousness

If you or someone you know is experiencing any of these symptoms, it is important to seek medical attention immediately.


Fortunately, there are several steps you can take to prevent heatstroke, including:

  • Stay hydrated: Drink plenty of water and other fluids to keep your body hydrated, especially during hot weather or physical activity.
  • Wear appropriate clothing: Choose lightweight, breathable clothing that allows sweat to evaporate easily.
  • Avoid strenuous activity during the hottest parts of the day: Try to schedule physical activity during cooler parts of the day, such as early morning or evening.
  • Stay in air-conditioned environments: If possible, stay in air-conditioned buildings or rooms during hot weather.
  • Take cool showers or baths: This can help lower your body temperature and prevent overheating.
  • Never leave children or pets in a parked car: Even on a mild day, the temperature inside a parked car can quickly rise to dangerous levels.


Heat stroke is dangerous and can cause irreparable medical damage. Should any symptoms occur, it is vital for immediate treatment. With temperatures rising in Thailand, it is highly important to take the necessary actions in order to minimize the risk as much as possible.
