Lucknow: A 32-year-old delivery executive felt dizzy while riding near Charbagh on Monday afternoon, stopped on the roadside and sat on the ground. Passersby gave him water and called an ambulance, which took him to a nearby hospital. Doctors examined him and found that he was suffering from dehydration and exhaustion due to the extreme heat.Doctors said that 2-3 such cases are being seen daily among bike riders in the city hospitals. As hot conditions continue, he warned that motorcycle and scooter riders are at greater risk of direct exposure to hot winds, engine heat and intense sunlight.Professor KK Savlani, Department of Medicine, King George’s Medical University, said riders should not ignore early warning signs such as dizziness, excessive sweating, headache or sudden fatigue. “If symptoms appear, stop immediately, move to shade, drink water and rest. If the condition does not improve, seek medical help,” he said.We see that even short journeys during peak hours create heat stress, especially in traffic where air flow is limited. “Dehydration and heatstroke can develop rapidly. Riders should avoid traveling between 12 noon and 4 pm and prefer early morning or late evening,” they warned.Dr. Ajay Tripathi, doctor of Lokbandhu Hospital, said that hydration should be planned. “Carry a water bottle with you during short journeys and more rehydration supplies for longer distances. Drink water every 15-20 minutes, whether thirsty or not,” he said. He said ORS or coconut water can help maintain energy levels.Doctors said breathable fabric jackets, light-colored helmets and scarves can reduce heat exposure. Parking in shady areas and choosing less congested routes can help reduce stress during the daily commute.
