The World Health Organization issued guidelines on simple steps to stay safe during summer heat waves to prevent heat-related illnesses [1].

These precautions are critical as high temperatures increase the risk of heat exhaustion and heat stroke, which can lead to severe health complications or death [1, 2].

Health officials advise individuals to drink water before they feel thirsty to maintain hydration [1]. They recommend wearing loose, light-colored clothing, and using sunscreen with a protection level of SPF30+ [1]. Taking regular breaks in the shade is also encouraged to lower body temperature [1].

Medical consultation is a key part of the safety strategy. The WHO said people should check with a doctor to determine how extreme heat may affect any regular medications they are taking [1].

"Heat exhaustion and heat stroke can be prevented by staying hydrated and finding a cool place to rest," the AOL Health Editorial Team said [2].

While these guidelines apply worldwide, specific regions are already facing challenges. Examples of areas dealing with high heat include India, the U.S. Capital Region, and Philadelphia [1, 4, 5].

In addition to personal care, some experts suggest environmental controls. A KCRA weather reporter said people should install an air conditioner if possible and keep up with regular maintenance for optimal cooling power [6].

Dietary choices can also play a role in managing temperature. Chef Kunal Kapur said jamun sharbat is a refreshing summer drink that helps beat the heat [7].

The official start of summer in the Northern Hemisphere is June [8], marking the period when these precautions become most vital for public health.

“Drink water before feeling thirsty.”

The emphasis on medication checks and specific SPF levels indicates that heat safety is moving beyond basic hydration to a more clinical approach. As global temperatures rise, public health agencies are treating heat not just as a seasonal inconvenience, but as a systemic health risk that interacts with pre-existing medical conditions.
