Choose the Water Temperature That Suits Your Needs

Jakarta (ANTARA) – Drinking water throughout the day is essential for good health, as water is involved in almost every biological process in the body.

Not drinking enough can lead to dehydration, which may cause symptoms such as headaches, fatigue and constipation, among others.

The Institute of Medicine (IOM) recommends that adult women consume 2 to 2.7 litres of water a day, while adult men should consume between 2.5 and 3.7 litres. Water needs can also be met by eating water-rich foods such as fruit and vegetables.

However, the temperature of the water we drink does not significantly affect how hydrated we are. According to a Health report broadcast on Tuesday (3 November) local time, both cold and warm water hydrate the body.

A 2025 study found that drinking cold water lowered core and skin temperatures more effectively than warm water among people exercising in hot conditions, and helped participants feel more comfortable in the heat.

Warm water, meanwhile, may ease symptoms such as a sore throat and nasal congestion when someone has the flu or a cold.

Some earlier studies suggest that hot drinks can provide greater relief for nasal symptoms and temporary relief from a runny nose, cough, sneezing, sore throat, chills and fatigue than the same drinks served at room temperature.

Sipping a cup of warm water or tea may also feel comforting when you are unwell and help ease symptoms such as a headache.

If you feel cold, warm or hot water may be a better choice than cold water. Studies suggest such drinks can reduce shivering and improve comfort or physical performance in cold weather.

Although cold water has been shown to increase the metabolic rate by about 4.5 per cent, the effect is very small and short-lived, with little impact on overall calorie burning.

There is no evidence that drinking cold water is more effective for weight loss than drinking water at room temperature or warm water. You should therefore choose whichever temperature helps you drink the most and stay optimally hydrated, which is key to energy balance.

Studies show that people who are dehydrated tend to have a higher body mass index (BMI) and are more likely to be obese than those who are well hydrated. Drinking more water may also help people consume fewer calories, creating the calorie deficit needed to reduce excess body fat.

Although water temperature generally has no effect on hydration or overall health, one option may be preferable in certain situations. Cold or cool water can improve thermal comfort and help regulate body temperature during exercise or physical work.

For people with swallowing disorders or oesophageal conditions, water temperature can affect comfort and ease of swallowing, including for those with certain conditions such as oesophageal motility disorders.

Cold water may be uncomfortable for people with sensitive teeth and can trigger headaches in some. Both cold and warm water hydrate you equally well, so the best choice is the one you will drink consistently.
