How Rising Night Temperatures Increase Disease Risk: This time in many parts of the country including Delhi, the heat is taking a toll on people’s health not only during the day but also at night. Whereas earlier night time used to give relief to the body from the heat of the day, now the increasing temperature is not allowing the body to take rest even at night. Doctors and researchers believe that continuous hot nights have now started increasing serious risks like heart diseases, dehydration and stroke.
mercury crosses 45 in delhi
According to the Meteorological Department, the temperature in Delhi has crossed 45 degrees Celsius and the situation may become more serious in the coming days. But it is not just the bright sunlight that is a matter of concern. Experts say that the temperature not falling at night is proving to be more dangerous for the body. Normally at night the body cools itself and recovers from the stress of the day. But when the heat persists even at night, the body remains under constant pressure.
What is the harm caused by the heat at night?
Research has revealed that hot nights can increase the risk of deaths related to heart disease and stroke. A study conducted by the National Institute of Health found that when an extremely hot day is followed by an unusually hot night, the body does not get relief and the health risks increase manifold. Especially the risk of stroke and heart disease was seen to be higher.

Why the problem for cities like Delhi?
Urban heat island effect is making this problem more serious in big cities like Delhi. Concrete buildings, little greenery and poor ventilation trap heat throughout the night. Its impact is most severe on those people who live in small houses or rooms without air conditioners. In many houses the temperature remains above 31 degrees Celsius even at night, due to which sleep is affected and the body does not get adequate rest.
Why is the problem increasing in Delhi?
The number of patients suffering from heat related diseases is also increasing rapidly in the hospitals of Delhi. According to Dr. Arvind Kumar Aggarwal, the number of patients with dehydration, heat exhaustion and initial symptoms of heat stroke has increased in the emergency ward. At the same time, Dr. Atul says that it is affecting children, elderly people and people suffering from heart, lung or kidney disease the most. Now doctors are not only advising to avoid sunlight during the day, but also to keep the body cool and hydrated at night. The World Health Organization has also included heat among the world’s biggest environmental health threats.
