Summer is here and so are the days of sweat and exhaustion. The rise in temperature and heat is not only annoying but is also a root cause of many health problems. Prolonged exposure to heat can cause illnesses such as exhaustion, dehydration, cramps and even sunstrokes. To prevent you from being affected by any of these problems, we have compiled a list of tricks that’ll help you stay healthy during these hot summer days.

Before we start with the solutions, let us first analyze the problem. While there are multiple health risks that one should worry about in the summers, one problem that’s most concerning is heat-related illnesses. These are caused due to the overheating of the body and there are two types of it - exertional and non-exertional.

  • Exertional heat-related illnesses: Prolonged exposure or physical exertion in high temperatures can cause exertional heat-related illnesses. People who spend long hours in a hot and humid climate are vulnerable to it. Policemen, military men, athletes and youngsters often suffer from this.
  • Non-exertional heat-related illnesses: It is commonly seen in older people who have underlying medical conditions such as diabetes, are bed-ridden and get dehydrated.
Heat-Related Illnesses vs Heatstroke

Heatstroke occurs when the hypothalamus is unable to control the temperature of the body and it rises to 40° celsius or even higher. It is a serious form of illness that involves the brain. The patient with heatstroke may get confused, have seizures or even slip into a coma, therefore it requires emergency treatment. When left untreated, heatstroke may damage the brain and other organs, and in extreme cases can also lead to death.
