Introduction
If a patient with heat stroke is conscious, able to swallow voluntarily, and not vomiting, but is dehydrated due to excessive sweating, drinking small amounts of electrolyte-containing water frequently can help replenish lost fluids and alleviate discomfort. In such cases, drinking water is not inappropriate. However, if the heat stroke patient is unconscious or confused, or experiencing severe vomiting, drinking water may easily cause coughing, choking, or suffocation.

It is not a wrong practice for heatstroke patients to drink an appropriate amount of water if they are conscious and not vomiting. However, drinking water may be inappropriate if the patient is confused or frequently vomiting. If any abnormalities occur, prompt medical attention is recommended. Detailed analysis is as follows:

If a heatstroke patient is conscious, able to swallow voluntarily, and not vomiting, and their body is dehydrated due to excessive sweating, drinking small amounts of water containing electrolytes multiple times can help replenish lost fluids and relieve discomfort. In this case, drinking water is not considered a wrong practice.

If a heatstroke patient is unconscious or in a state of confusion, or experiences severe vomiting, drinking water at this time may easily trigger coughing, choking, or worsen the physical burden, making it ineffective for rehydration. In such situations, drinking water could be considered inappropriate.

When encountering a heatstroke patient, first assess their consciousness and swallowing ability before deciding whether to offer water. Avoid force-feeding fluids, and seek immediate medical assistance. If hydration is necessary during transport, carefully control both the volume and speed of fluid administration. Follow professional medical guidance upon arrival at the healthcare facility.
