Singapore Launches Heat Stress Advisory for Safe Outdoor Activities in High Temperatures

Singapore has launched a new service called Heat Stress Advisory to help users gauge and minimize risks associated with heat when engaging in outdoor activities. The advisory is based on the Wet Bulb Globe Temperature WBGT, an internationally recognized indicator that takes into account multiple environmental factors contributing to heat stress, such as r temperature, humidity, wind speed, and solar radiation.

The Heat Stress Advisory categorizes risk levels into three categories: low, moderate, and high, each corresponding to varying degrees of potential heat-related illnesses like heat cramps, exhaustion, or heatstroke. This information can be accessed through the myENV app or Singapore's official weather website by checking WBGT readings from sensors located closest to the user's location.

The sensors are strategically placed in sports stadiums across the island and will increase in number over the next two years, with more installations planned for high-traffic areas as well. The advisory also provides actionable tips on how individuals can adjust their activities, take protective measures, or choose appropriate attire based on WBGT readings.

Special attention is given to groups at a higher risk of heat stress, such as the elderly, children, infants, and pregnant women. They are encouraged to exercise caution when participating in prolonged outdoor activities. Guidance for those required to engage in such activities due to work or school responsibilities can be found through sector- issued by relevant authorities like the Ministry of Manpower.

Singapore has experienced an increase in temperature levels over recent years; May 2023 saw a record-high dly maximum temperature of 37°C in Ang Mo Kio. Since 2013, Singapore has seen its warmest decade on record.

In response to this heatwave, several schools have revised their uniform policies, allowing students to opt for physical education attire instead of full uniforms and permit polo shirts to be worn untucked.
