Bangkok heat index reaches dangerous level, authorities warn of rising health risks

The Bangkok heat index has reached a “dangerous” level, raising concern among authorities and residents as extreme weather continues across the city. Officials warned that conditions could worsen, with the heat index possibly exceeding 52°C in the coming days.

The Bangkok Metropolitan Administration (BMA) said the situation was recorded on April 6, when the “feels like” temperature reached a high-risk range. This level is considered dangerous and may lead to serious health problems if people are exposed for too long.

Heat Index Reaches Critical Range

According to the BMA’s Environment Department, the maximum heat index recorded fell between 42°C and 51.9°C. This range is officially classified as “dangerous.” Authorities also warned that it could rise into the “very dangerous” category, which begins at 52°C.

While the actual air temperature remained between 38°C and 40°C, high humidity made conditions feel much hotter. This combination increases pressure on the human body and raises the risk of heat-related illnesses.

Health Risks Increase Across the City

Officials explained that such extreme heat can quickly affect the body. Common warning signs include dizziness, fatigue, headaches, a rapid pulse, and unusual sweating. In more serious cases, it may lead to heat exhaustion or heatstroke.

People who experience these symptoms are advised to move to a shaded or air-conditioned place immediately. Resting and cooling down are important steps to prevent the condition from becoming more severe.

Public Urged to Take Precautions

The BMA has asked residents to limit outdoor activities, especially during peak hours between 11 am and 3 pm. People are also encouraged to drink water regularly and avoid staying in direct sunlight for long periods.

High-risk groups, including children, older adults, pregnant women, and those with existing health conditions, are strongly advised to stay indoors as much as possible. Authorities also recommend following updates through official platforms for the latest information on heat conditions.
