As the summer sun intensifies, it brings with it a season of outdoor activities, vacations, and, unfortunately, a host of health concerns. Among the most vulnerable to the summer heat are children, whose bodies and brains are particularly susceptible to the adverse effects of high temperatures. Understanding how summer heat can impact the brain health of children is crucial for parents and caregivers. By understanding the impact of summer heat on brain health and taking appropriate measures, we can ensure that our children enjoy a safe and healthy summer.
Hence we got in touch with Dr Vipul Gupta, Chief of Neurointervention and Co-Chief of the Stroke Unit, at Artemis Hospital, Gurugram who has shared insights on how excessive heat can impact children’s brain health.

Impact of Heatwave on Children's Brain Health

Physiological Vulnerabilities
Children's bodies are not as efficient at regulating temperature as those of adults. Their higher surface-area-to-body-mass ratio, greater absorption of heat, and lower sweating capacity make them more prone to heat-related illnesses. The brain, being a highly sensitive organ, is particularly vulnerable to these changes.
Dehydration and Electrolyte Imbalance
One of the primary risks associated with summer heat is dehydration. Children are often too engrossed in play to remember to drink water, leading to a significant loss of fluids and electrolytes. Dehydration can cause the brain to function less efficiently, resulting in symptoms such as dizziness, confusion, and lethargy. Severe dehydration can lead to more serious conditions like heat exhaustion or heat stroke, both of which can cause brain damage if not promptly treated.
Heat Stroke and Neurological Impact
Heat stroke is a medical emergency that occurs when the body's temperature regulation system fails, leading to a rapid rise in core body temperature. In children, this condition can develop quickly and cause severe neurological damage. Symptoms include high fever, altered mental state, seizures, and loss of consciousness. The impact on the brain can be profound, potentially resulting in long-term cognitive and motor deficits.
Cognitive Performance
Even moderate heat exposure can affect a child's cognitive performance. Studies have shown that high temperatures can impair attention, memory, and overall cognitive function. This can have immediate effects on a child's ability to learn and perform in school, as well as long-term implications for their developmental trajectory.
Behavioural Changes
Heat can also influence a child's behaviour and emotional state. Irritability, mood swings, and decreased ability to concentrate are common during periods of high heat. These behavioural changes can affect a child's social interactions and academic performance, leading to increased stress and anxiety.
Preventative Measures
Dr Vipul Gupta shares that to mitigate the above mentioned risks, it is essential to implement preventive measures. Parents and caregivers can take following measures:
- Parents and caregivers should encourage regular water intake, especially during outdoor activities.
- Provide access to shaded areas and cool environments, as it can help reduce the risk of heat exposure.
- Wearing lightweight, breathable clothing and applying sunscreen can also protect children from the harmful effects of the sun.
- In educational settings, schools should adjust schedules to avoid outdoor activities during peak heat hours and ensure that classrooms are well-ventilated or air-conditioned.
- Educating children about the importance of hydration and recognizing the signs of heat-related illnesses can empower them to take proactive steps in protecting their health.
“As temperatures soar, the well-being of our children demands vigilant attention. By understanding the impact of summer heat on brain health and taking appropriate measures, we can ensure that our children enjoy a safe and healthy summer,” he said.
