Children at Higher Risk in Heatwaves: How to Protect Them

Children face greater risks during heatwaves than healthy adults due to biological differences in how their bodies regulate temperature. The hypothalamus, the brain's thermostat, controls heat regulation by triggering responses like sweating and vasodilation. However, in children under five, this system is not fully developed, leading to reduced sweating and an inability to recognize thirst. Their smaller size also means they absorb heat faster, and their higher activity levels increase metabolic heat production. These factors cause their core temperatures to rise more quickly and stay elevated compared to adults. ## Risks of Overheating in Children When exposed to excessive heat, children may develop heat exhaustion, characterized by excessive sweating, pale and clammy skin, dizziness, irritability, and intense thirst. If untreated, symptoms can worsen to include muscle cramps, nausea, or vomiting. Immediate action is crucial, such as moving the child to a cooler, shaded area, providing cold drinks, and cooling them with wet towels. Failure to intervene can lead to heatstroke, a severe condition where the brain's thermostat fails. Symptoms include hot, flushed, and dry skin, headaches, confusion, restlessness, and a body temperature exceeding 40°C. Heatstroke is a medical emergency and can result in unconsciousness. Overheating poses particularly serious risks for children under five, with babies being especially vulnerable. High temperatures increase the risk of sudden infant death syndrome (Sids), making it essential for parents to take preventive measures. ## Keeping Children Safe in Hot Weather During heatwaves, parents should prioritize hydration, rest in cool areas, and appropriate clothing for their children. Dr. Jessica Mee, an expert in heat physiology at the University of Worcester, advises ensuring children drink plenty of fluids, rest in shaded spots, wear light and loose-fitting clothes, and watch for signs of heat distress like fatigue, dizziness, or nausea. Babies require special attention, as they rely on adults to adapt to their needs. In extreme heat, they may need extra breast or bottle feeds. Parents should avoid leaving babies in prams, which can become hot and airless, and ensure good air circulation when putting them down to sleep. The National Health Service recommends maintaining a room temperature between 16°C and 20°C for newborns. If using a fan, it should not be pointed directly at the baby but used to circulate air. In the absence of a fan, cool, damp cloths can be applied to the baby's body, but parents should monitor them regularly to prevent overheating or cooling.
