BANGKOK, Thailand – The Thai government has issued a public health warning regarding extreme heat and the rising risk of heatstroke.
Deputy Government Spokesperson Airin Phanrit shared data from the Department of Disease Control’s Digital Disease Surveillance system, which recorded 182 heat-related illnesses and 21 fatalities in 2025. The Northeastern region had the highest number of deaths, with outdoor laborers identified as the most at-risk group. Men accounted for nearly 60% of cases, especially among those aged 15–34 and the elderly. Reported conditions included heat exhaustion, heat syncope, and heat cramps, with 17 severe cases of heatstroke.
In 2025, 21 fatalities were reported across 16 provinces, with Udon Thani recording the highest number. Sixty-seven percent of deaths occurred outdoors, peaking in April when temperatures were highest. Key risk factors included pre-existing conditions such as hypertension and diabetes, along with alcohol consumption.
To prevent heatstroke, the government advises avoiding outdoor activities between 11 a.m. and 3 p.m. and recommends that outdoor workers take frequent breaks in the shade. Public health guidelines stress the importance of drinking at least one glass of water every hour, wearing light-colored, breathable clothing, and avoiding alcohol or high-sugar drinks. Authorities also warn against leaving children or pets in parked vehicles, as temperatures inside can become fatal within 20 minutes.
The government urges the public to monitor weather forecasts and seek immediate medical attention if symptoms of heat-related illness appear, especially among vulnerable groups such as the elderly, children, pregnant women, outdoor workers, athletes, and those with underlying health conditions.
