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.

According to IMD, when the temperature in an area increases much more than normal, then it is declared a heatwave. In the plains, which includes Delhi, heatwave conditions are considered when the temperature is 40 degrees Celsius or more and is recorded 4.5 to 6.4 degrees above normal.

At the same time, if the temperature reaches more than 6.4 degrees above normal, then it is considered a severe heatwave. Apart from this, if the temperature reaches 45 degrees Celsius or more, a heatwave is declared, no matter what the difference is from normal temperature. Experts say that this is not just normal heat but a dangerous situation, which can prove fatal for children, elderly and people working outside.

Be careful about health

These days Delhi is struggling with scorching heat. The heat of the sun is such that it becomes difficult to go out since morning. Heat waves are being felt on the roads and the situation becomes worse by afternoon. This extreme heat affects children the most, who go to school every day and sit in class for hours. In view of this danger, the Delhi government has taken an important decision, which is directly related to the health of children.

The government has issued new guidelines for all schools. Now children’s health will be given priority before studies. The order is clear that now a special kind of bell will ring in every school, which has been named ‘Water Bell’. This bell will ring not to end the class, but to remind the children to drink water.

In summer, children are often busy playing or studying and forget to drink water on time. This causes lack of water in the body, which is called dehydration. Many times this carelessness becomes the cause of serious problems like dizziness, vomiting, headache and heat stroke. Doctors also constantly advise that one should keep drinking water at regular intervals during summer. Keeping this in mind, the government has implemented this new system.

What are the new guidelines?

According to the new guidelines, the school bell will ring every 45 to 60 minutes. As soon as the bell rings, the teacher will give the children a break for a few minutes so that they can drink water comfortably. Schools will also have to ensure that clean and cool water is available to children. Where needed, arrangements for additional water coolers or filters will also have to be made.

The government says that in this period of scorching heat, the pressure of studies should not be so much that children ignore their health. Therefore, this system will have to be implemented compulsorily in all government and private schools. Clear instructions have been given to the school administration to strictly follow this rule.

There is a red alert like situation in Delhi these days due to heatwave. The temperature is continuously reaching around 45 degrees. In such a situation, it quickly affects the children’s body. Small children often do not pay attention even when they feel thirsty. For this reason, this ‘Water Bell’ is being considered a small but very important initiative.
