Heat is increasingly becoming a public health threat for children and young people as the effects of rising temperatures put them at risk of contracting illnesses and sustaining injuries, or interrupting daily activities, say health professionals.

This is due to the fact that children's bodies do not control temperatures effectively, and also because they generate body heat when playing more effectively than adult bodies. In addition, children rely on adults to be able to identify signs of dehydration or heat stress.

Why are children vulnerable?

Children have lower sweat rates and higher body heat, and thus, they tend to become dehydrated faster. Babies and toddlers, sick children, or those who take some forms of medication are at greater risk of heat effects.

Heat can lead to dehydration, heat exhaustion, and heatstroke. Poor air quality or smoke from wildfires could make heat worse for people with asthma.

How Does Heat Impact Learning and Life?

Heatwaves are affecting school attendance and outdoor programs. Overheated rooms may make students unable to focus and hinder the process of learning. The classes at schools in various countries are being shortened or suspended due to heatwaves because most buildings are not adapted for long-term heat conditions.

Sports and other outdoor activities are also influenced by heat waves. It is advised to limit vigorous physical activities during the hottest hours and to provide children with drinking water and shade.

Do heatwaves occur more often now?

According to scientists, the phenomenon of heatwaves becomes more common due to climate change. An increase in temperatures in the world results in an increase in the likelihood of heatwaves in various parts of the world, such as Europe, North America, and even some parts of Asia.

According to the representatives of the field of public health, it is estimated that the current generation of kids will face significantly more heatwaves throughout their lives compared to previous generations if the world's temperature does not stabilize.

What steps can be taken to decrease risk?

According to health organizations, one should ensure kids get enough water, limit their stay outside at noon in the direct sunlight, and ensure that their educational establishments have proper cooling and ventilation. Also, parents should pay attention to possible signs of heat-related disease, such as dizziness, excessive fatigue, nausea, or confusion.
