 To what extent does drinking cold water to relieve heat pose a health risk?

When life is hectic in the intense heat of summer, a glass of cold water seems to bring a momentary relief. Many people drink cold water from the fridge or iced drinks to relieve fatigue after coming home from the sweaty outdoors or from the scorching sun. But experts say that even if this habit provides temporary relief, it can cause serious harm to the body.

Digestive problems

According to doctors, cold water has a direct effect on the digestive process.

When the body is overheated in extreme heat, drinking cold water constricts the blood vessels in the stomach. As a result, food takes longer to digest and the digestive process slows down. Especially after oily food, drinking cold water can cause fat to accumulate, which further complicates digestive problems.

Throat and respiratory tract infections

Suddenly drinking cold water after coming home from the sun can increase sore throat, cold and cough, and tonsil problems.

It produces excess mucus in the respiratory tract, which obstructs breathing and increases the risk of various types of infections. This practice is very risky for those who have cold sensitivity or asthma.

Effects on the heart

Extremely cold water has been proven in several tests to reduce the heart rate. The vagus nerve, which regulates heart rate, is stimulated by it.

Cold water's action on the vagus nerve can cause the heart rate to drop, which is particularly harmful for heart patients.

Damage to the teeth

The teeth's outer layer, or enamel, may be harmed by cold water. The tooth's outer layer shrinks when it is exposed to hot or cold water, which can lead to enamel cracks. Tooth sensitivity is heightened as a result of this.

Dehydration risk

It may appear that the body's water requirements have been satisfied since cold water quickly satisfies thirst.

However, the body frequently does not receive enough water. This false belief may cause dehydration, which impairs the body's ability to function normally.

Reasons for headaches and migraines

For people who get headaches or migraines, cold water might be harmful. The brain's blood arteries quickly constrict when you drink cold water, which can exacerbate headaches and migraines.

Professional guidance

According to experts, drinking enough water—ideally at room temperature or slightly chilled—is the only way to keep healthy during the heat. After taking a short break, it is advisable to consume room temperature water rather than cold water right away after returning from the outdoors. Additionally, you can drink fruit juice, coconut water, or mild lemonade to make sure you get 8–10 glasses of water each day.
