Chennai, Apr 27: The India Meteorological Department (IMD) has cautioned that temperatures are set to rise further across several districts of Tamil Nadu in the coming days, raising concerns over heat-related health risks.

As the mercury continues to climb, medical professionals are warning of a growing likelihood of dehydration and heat-induced illnesses. Doctors stress that staying protected during extreme summer conditions depends largely on two key measures—remaining alert to symptoms and regularly consuming Oral Rehydration Solution (ORS).

Under normal conditions, the human body maintains an average temperature of about 36.9°C. When surrounding temperatures exceed this level, the body absorbs additional heat and relies on natural cooling processes such as sweating and faster breathing. However, prolonged exposure to intense heat can overwhelm these mechanisms.

Excessive sweating results in the loss of water, glucose, and essential salts, increasing the risk of dehydration. If untreated, this can lead to symptoms like fatigue, dizziness, muscle cramps, and in severe cases, heatstroke or even loss of consciousness. Health experts also caution that dehydration can negatively impact vital organs such as the kidneys and heart.

Early warning signs to watch for include dry mouth, dark urine, weakness, cramps, and light-headedness. While drinking water is essential, doctors point out that it may not be enough during extreme heat. ORS plays a critical role in restoring electrolyte balance and maintaining proper hydration.

According to guidelines from the World Health Organization (WHO), a standard ORS sachet contains a mix of sodium chloride, glucose, potassium chloride, and trisodium citrate. It should be dissolved in one litre of boiled and cooled water and consumed within 24 hours for best results.

With heatwave conditions expected to persist, authorities advise people to limit outdoor exposure during peak daytime hours, stay well-hydrated, and keep ORS readily available to avoid serious health complications.
