Thailand Issues Heat Alert as Heat Index Reaches “Extreme Danger” Levels, High Risk Through May

Bangkok, Thailand –  Thailand’s health authorities have issued a nationwide warning as the Heat Index continues to rise to dangerous levels, with projections indicating it could reach the “extreme danger” category and persist through mid May.

 

 

According to the Bangkok Metropolitan Administration’s Environment Department, current heat index levels have already reached the “danger” threshold, prompting advisories for the public to closely monitor their health. The heat index, which reflects how hot it actually feels by combining air temperature and humidity, is considered a more accurate indicator of heat-related health risks than temperature alone.

 

 

Authorities classify the heat index into four levels. Values between 27.0 - 32.9°C fall under “Caution,” where vulnerable individuals are advised to stay hydrated. Levels of 33.0 - 41.9°C are categorized as “Warning,” requiring reduced outdoor activity, especially between late morning and mid afternoon. The “Danger” level, ranging from 42.0 - 51.9°C, calls for heightened self monitoring and immediate medical attention if symptoms occur. When the index exceeds 52°C, it enters the “Extreme Danger” category, where all outdoor activities should be avoided entirely.

 

Health experts warn that prolonged exposure to extreme heat can lead to a range of conditions, from fatigue and dizziness to severe complications such as Heatstroke, a life threatening condition that requires urgent medical attention. Symptoms may include high body temperature, red and dry skin, confusion, and loss of consciousness.

 

 

The Department of Health Thailand has also raised concerns over the ongoing heatwave. Dr. Amporn Benjapolpitak, Director-General of the department, stated that Thailand is experiencing prolonged extreme heat, with forecasts indicating that the heat index could reach between 52 - 60 °C in several areas during April, remaining at critical levels into May.

 

Particular concern has been raised for vulnerable populations, including young children, pregnant women, the elderly, individuals with chronic illnesses, and those working outdoors. Children are especially at risk due to their limited ability to regulate body temperature and their tendency to engage in outdoor activities. Pregnant women also face increased health risks due to physiological changes that make heat dissipation more difficult, potentially affecting both maternal and fetal health.

 

Health authorities are urging the public to take preventive measures, including drinking sufficient water, avoiding outdoor exposure during peak heat hours, wearing breathable clothing, and staying in well ventilated environments. Immediate action is recommended if signs of heatstroke are observed, including moving the affected person to a cooler area and seeking medical care without delay.

 

With extreme heat conditions expected to persist, authorities emphasize the importance of public awareness and proactive health protection to reduce the risk of serious heat related illnesses during this period.
