Summer brings in disorders like heat cramps, heat exhaustion, heat stroke, typhoid, jaundice and diarrhea. The answer lies in prevention said Dr. K K Aggarwal.

Heat disorders are caused by too much heat production or by too little heat loss.

• Strenuous exertion in a very hot environment should be avoided.

• Best summer dress is light, loose-fitting clothing made of cloth that breathes such as cotton.

• Fluids and salts lost through sweating can be replaced by consuming lightly salted foods and beverages, such as salted lemon water.

• To replace adequate amounts of fluids, drinking must continue even after thirst is quenched.

• When exertion in a hot environment cannot be avoided, drinking plenty of fluids and frequently cooling the skin can help keep body temperature near normal.

• People engaged in outdoor activities who drink large quantities of water may dilute the sodium in the blood. Consuming salt can alleviate this problem.

• Enclosed, poorly ventilated spaces, such as a car, can heat up rapidly. In hot weather, the interior of a closed car can heat from 80 to 120° F in 15 minutes. Children and pets should never be left in such an environment, even for a few minutes.

• Maintain food and water hygiene during this season.

• Do not eat cut open fruits and vegetables.

• Remember the formula cook it, boil it, peel it, heat it or forget it.
