Islamabad: (Right Now News) Millions worldwide, including in Pakistan, face extreme temperatures due to severe heatwaves. Climate change has intensified the severity and duration of these heatwaves.

According to research by the University of Roehampton in the UK, the human body struggles to regulate heat at 40 degrees Celsius. The study involved 13 individuals resting for an hour in environments with varying temperatures and humidity.

Research from Pennsylvania State University in the US also found that a combination of high humidity and temperature prevents the body from cooling effectively at just 31 degrees. This increases stress on the heart and other bodily systems.

The significance of this research lies in the profound impact of rising heat and humidity on human health. Older individuals, in particular, have a reduced capacity to withstand heat.

It is important to note that these studies have been published in medical journals, and readers are advised to consult their healthcare providers.
