Heat Cramps

Heat cramps are painful muscle contractions caused by physical exertion in a hot environment. They often result from dehydration and loss of electrolytes due to profuse sweating.

Symptoms include muscle spasms, notably in the legs, abdomen, or arms. Other symptoms may include nausea, vomiting, fatigue, and increased heart rate.

Rehydration with water and electrolytes, rest in a cool setting, and stretching the affected muscles can often alleviate the symptoms. 

Although heat cramps are the least severe type of heat-related illness, they are an early indication that the body is having trouble with the heat. It's important to note that severe instances may require medical attention, especially if symptoms persist or worsen.
