The highest temperature on Wednesday is expected to touch 39 degrees, which is unusual for April.With temperatures steadily climbing, the Health Department has issued a public advisory urging residents to take precautions against heatwave and heat-related illnesses. While local residents turn to coconut water and good-old watermelon to cool themselves, the street vendors are dishing out their own versions of “fruit salad coolers”.Civil Surgeon Amritsar, Dr Satinderjit Singh Bajaj, cautioned that prolonged exposure to extreme heat can lead to serious health complications, including dehydration, heatstroke, fever, headaches, vomiting and diarrhoea.He stressed that vulnerable groups such as the elderly, young children and individuals with pre-existing medical conditions must exercise extra care during this period.“People often underestimate the impact of rising temperatures. Symptoms like fatigue, high fever, vomiting and an increased heart rate can escalate quickly if not addressed in time,” Dr Bajaj said.He advised residents to avoid self-medication and instead consult qualified doctors at the nearest government health centre if they experience any warning signs.Highlighting preventive measures, Dr Rajnish, Senior Medical Officer, Civil Hospital urged people to stay well-hydrated by consuming plenty of fluids such as lemonade, lassi, coconut water and Oral Rehydration Solution (ORS). He also recommended wearing light-coloured, loose cotton clothing to help the body stay cool, and covering the head and body while stepping outdoors.Residents have been advised to limit exposure to direct sunlight, particularly during peak afternoon hours, and to prioritise balanced, home-cooked meals over outside food.Maintaining hygiene in and around homes is equally important to prevent the spread of seasonal illnesses, he added.The health department has called on citizens to remain vigilant and adopt simple preventive steps to safeguard themselves and their families as the summer heat intensifies.Dos and Don’ts during heatwaveDos:Drink plenty of fluids like water, lemonade, lassi, coconut water and ORSWear light-coloured, loose cotton clothesCover your head and body while going out in the sunEat fresh, balanced and home-cooked mealsKeep surroundings clean and hygienicSeek medical advice immediately if symptoms appearDon’ts:Avoid going out in direct sunlight, especially during peak afternoon hoursDo not ignore early symptoms like fatigue, dizziness or vomitingAvoid self-medication without consulting a doctorDo not consume stale or unhygienic foodAvoid dehydration by skipping meals or fluids
