Chennai, Apr 15:
With Chennai reeling under intense summer heat, health experts are urging residents to stay hydrated while also exercising caution over what they consume. Rising temperatures have made people more vulnerable to dehydration and heat-related illnesses, making adequate fluid intake essential during this period.
Doctors warn that prolonged exposure to extreme heat can lead to serious conditions such as heat stroke, low blood pressure, low blood sugar and skin-related issues. “During extreme summer conditions, dehydration can happen faster than people expect. Even mild dehydration can affect energy levels, blood pressure and overall health,” said Dr. R. Kumar, a general physician.
Amid the scorching weather, many people turn to colourful and refreshing drinks sold by roadside vendors, including lemon soda, sarbath, orange juice and jigarthanda. While these beverages may appear tempting, their safety and hygiene standards often remain questionable.
Medical experts caution that many roadside vendors prepare drinks under poor sanitary conditions. In several cases, contaminated water may be used, either unknowingly or due to lack of proper facilities. The use of unclean glasses, artificial colours and excessive sugar further adds to the health risks. Despite visible hygiene concerns, people often consume these drinks due to extreme thirst.
“Contaminated water is one of the biggest causes of summer infections. People tend to ignore hygiene when they are thirsty, but that can lead to serious gastrointestinal problems,” said Dr. Meena S, a public health specialist.
Consumption of such beverages can result in viral fever, infections, diarrhoea, stomach upset and even food poisoning in severe cases. Doctors say such cases typically see a rise during peak summer months.
While a few roadside vendors may maintain proper hygiene, identifying safe options can be difficult for the general public. As a safer alternative, experts recommend opting for natural drinks such as tender coconut water, which is generally free from contamination and rich in electrolytes. However, its price often rises due to high seasonal demand.
“Natural drinks like coconut water are among the safest choices during summer as they are sterile and help replenish electrolytes,” said Dr. Priya Nair, a nutritionist.
Health experts also advise preparing beverages at home, including lemonade, watermelon juice and orange juice, which are both safe and nutritious. Oral Rehydration Solutions (ORS) can be used occasionally to treat dehydration but should not replace regular fluid intake.
“ORS is useful for quick rehydration, but it should not be consumed as a daily substitute for water or fresh juices,” said Dr. Arvind Rao, an internal medicine specialist.
With temperatures continuing to soar, doctors stress that while staying hydrated is critical, choosing safe and hygienic sources of fluids is equally important to avoid preventable health complications.
