Jurong East Residents Need 3+ Liters Daily to Beat 80% Humidity

Health authorities in Jurong East now recommend adults drink 3.5 litres of fluid each day when outdoor temperatures stay above 31 degrees Celsius, a threshold crossed on 42 days so far this year.

The advice comes as the National Environment Agency recorded average relative humidity of 84 percent across the first week of July, raising dehydration risk for people who walk or cycle between the Jurong East MRT interchange and nearby workplaces.

Local programmes track intake

The Jurong East Community Club launched its monthly Hydration Check sessions last April at the centre on Jurong Gateway Road, where volunteers measure urine colour and hand out marked 750-millilitre bottles. At the same time the ActiveSG fitness team at Jurong East Sports Complex added free electrolyte stations near the running track that refill every two hours from 7am to 9pm.

Both sites sit within a 10-minute walk of each other, making it easy for morning market shoppers at Jurong East Market and Food Centre to top up before heading home along Boon Lay Way.

Numbers and choices

A 2025 survey by the Health Promotion Board found that adults in the Jurong planning area averaged only 2.1 litres daily, well below the new target. Plain water still costs 30 cents for a 500-millilitre cup at most hawker stalls, while fresh coconut water from the same vendors sells for $2.50 a serving and supplies natural potassium that helps replace sweat losses faster than plain water alone.

Nutritionists at the nearby Ng Teng Fong General Hospital advise limiting sweetened drinks to one serving per day and suggest alternating between water and unsweetened barley or chrysanthemum tea available at the food centre.

People can start today by filling a reusable bottle at the sports complex tap before 8am and refilling it once at the community club station by mid-afternoon, then tracking colour at the next Hydration Check on 23 July.
