Do patients with heatstroke need to be restricted from water?

Generally, heatstroke patients who experience vomiting or loss of consciousness should temporarily avoid drinking water. If the patient is conscious and not vomiting, there is no need to restrict water intake. If any abnormalities occur, prompt medical attention is recommended. Detailed explanation is as follows:

If a heatstroke patient is unconscious or frequently vomiting, drinking water may easily cause coughing, aspiration, and subsequent airway obstruction, worsening the condition. In such cases, water intake should be temporarily restricted, and hydration should be maintained through intravenous fluid replacement instead.

If a heatstroke patient is alert, able to swallow independently, and not vomiting, their body may have lost significant fluids due to high fever. In this situation, drinking moderate amounts of cool beverages containing salt can help replenish bodily fluids and alleviate symptoms of dehydration. Therefore, water restriction is unnecessary in these cases.

When managing a heatstroke patient, first assess their consciousness and swallowing ability before deciding whether to provide fluid replacement. Simultaneously, rapid cooling measures should be taken and immediate transport to a medical facility arranged. If hydration is necessary during transport, it should be done slowly and in small amounts. After reaching medical care, follow the healthcare provider's instructions strictly to avoid risks associated with improper management.
