The heat index could soar to a dangerous 60 degrees Celsius in early April, posing a major threat to vulnerable groups the Digital Economy and Society (DES) Ministry warned on Monday.
The heat index combines air temperature with relative humidity, reflecting what the body actually feels rather than the ambient temperature. High humidity significantly amplifies heat stress.
The DES cautioned that a high heat index poses particular risk for vulnerable groups such as the elderly, children, pregnant women, people with chronic illnesses or obesity, outdoor workers, psychiatric patients and alcoholics.
People are advised to take note of weather forecasts and heat index updates and avoid outdoor activities from 1pm to 4pm. They should drink around eight glasses of water during the day and not wait until they feel thirsty.
Alcohol and high-sugar drinks like sodas and other sweetened beverages should be avoided during the heat. Lightweight, breathable clothing, hats and umbrellas are recommended when venturing outside.
People taking certain medications, including antihypertensives, decongestants, diuretics and psychiatric drugs, should monitor their condition closely because some medications can impair the body's ability to regulate temperature.
Those exercising or working outdoors should do so in groups and watch each other for signs of heat-related stress, the ministry said.
