India has a long summer and rainy season in most parts of the country. The temperatures can go very high and although rains bring relief, the humidity increases the problems.

Heat in itself is good for the human body, despite the discomfort which can be debilitating.

Most of us use various methods to alleviate the discomforts; especially the use of water coolers and air conditioners is widespread.

The extensive and prolonged use of these cooling methods is associated with certain problems too. A sudden and frequent change of ambient temperature and humidity is a major cause for muscle spasm and cramps. These are compounded by a general reduction of physical activity and an exercise, and an overall lethargy, both physical and mental.

Summer and rains are associated with an increase in infections. The food consumed during these seasons is reduced in quantity with a predilection for carbohydrates for quick energy and the preference is for cold items and more liquids. To an extent these are necessary, but excessive consumption of cold food, sweetened liquids (mainly commercial carbonated drinks with extremely high sugar content), can be detrimental to health.
