What is a common symptom of heat exhaustion?

Nausea is indeed a common symptom of heat exhaustion, which is a heat-related illness caused by excessive loss of water and salt through sweating. When the body overheats, it reacts by attempting to cool itself down, leading to various symptoms. Nausea can occur as the body struggles to maintain its proper functions in response to dehydration and electrolyte imbalance. Alongside nausea, individuals experiencing heat exhaustion might also exhibit symptoms such as heavy sweating, weakness, and increased heart rate as their body attempts to cope with the elevated temperature.

On the other hand, symptoms like blurred vision typically do not align with heat exhaustion but may be related to other medical conditions. Intense shivering is characteristic of hypothermia, while muscle growth is not a symptom associated with heat exhaustion at all but instead relates to adequate nutrition and exercise. Understanding these distinctions is important for recognizing the signs of heat exhaustion and responding appropriately to ensure safety and recovery.
