Why seniors should drink warm liquids on scorching hot days

Warm fluids recommended during heatwaves

During periods of extreme temperatures, our natural instinct is to reach for cold drinks to cool down quickly. However, nutrition and medical specialists recommend a different approach, particularly for elderly people: consuming warm fluids, such as tea, can be far more beneficial for the body on sweltering days.

Why does this method work?

The explanation lies in the human body's natural thermoregulation mechanism. When we consume a warm drink, the body's internal temperature rises slightly, which stimulates perspiration. As sweat evaporates from the skin, the body cools down naturally and efficiently, ultimately reaching a lower body temperature than it would after consuming cold fluids.

Why is this advice particularly important for seniors?

Elderly people are the most vulnerable section of the population during heatwaves. As we age, the thermoregulation mechanism becomes less efficient, and the sensation of thirst diminishes significantly. This increases the risk of dehydration and heat stroke — conditions that can be dangerous or even fatal for older people.

Practical recommendations for hot days

• Drink lukewarm tea or water at room temperature throughout the day, even if you do not feel thirsty
• Avoid very cold drinks, which can cause an unpleasant thermal contrast and may inhibit natural perspiration
• Avoid alcoholic drinks and excessive caffeine, as these worsen dehydration
• Hydrate regularly, in small, frequent amounts, without waiting until you feel thirsty
• Opt for herbal teas without added sugar, which also offer additional health benefits

A simple habit with a significant impact on health

For seniors living at home or in care homes, adopting this simple habit can make a meaningful difference during the summer months. Family members and carers are encouraged to ensure that the elderly people in their care consume sufficient warm fluids throughout days of high temperatures, thereby helping to prevent complications associated with excessive heat.
