Expert identifies groups most at risk during sudden temperature spikes

India is currently facing a severe heatwave, with the India Meteorological Department predicting sweltering conditions across the northwest and central regions.

Recent AQI.in rankings show that 19 of the world's 20 hottest cities are currently in India. Dr Mukta Agarwal from Manipal Hospital, Ghaziabad, warns that early heatwaves have a severe impact because temperatures rise before people can adapt.

Who is most at risk during early heatwaves?

According to Dr Mukta, while heat impacts everyone, specific high-risk groups must take precautions:

• Elderly individuals: Reduced ability to regulate temperature and lower fluid intake increase vulnerability.
• Infants and young children: Their bodies heat up faster, and they depend on caregivers.
• People with chronic conditions: Heart, diabetes, and kidney disorders can worsen under stress.
• Outdoor workers: Labourers and delivery personnel face excessive fluid loss and heat stroke.
• Pregnant women: Increased metabolic rates make them prone to dehydration.
• People on certain medications: Some drugs interfere with sweating or fluid retention.

Heat wave symptoms and how to stay safe

Prolonged exposure leads to dehydration or heat stroke. Dr Mukta identified symptoms including:

• dizziness
• fatigue
• excessive sweating or dry skin
• nausea
• headaches
• confusion

To mitigate risks, she recommended: “Stay well-hydrated, avoid stepping out during peak afternoon hours, wear light and breathable clothing, and ensure proper ventilation indoors.

People should check on vulnerable individuals, especially the elderly and children, as it is equally important.

Early action and mindful habits can significantly reduce the risks and help the body cope better with sudden heat changes.”
