Extreme Heat: At present, the effect of extreme heat is being seen across the country and now Nautapa is also going to start soon. Generally, people feel that heat bothers them the most only during the day, especially in the afternoon when by around 2 o’clock the sun becomes so strong that even people’s shirts get drenched with sweat. It becomes difficult to go out on the road and the body becomes completely tired. But now doctors and meteorologists say that not only the sunlight of the day but also the heat of the night is having a bad effect on people’s health. Many times this effect increases gradually and people do not understand until their health becomes worse.

People’s sleep is decreasing due to hot nights

In a recent study, data related to sleep of about 47 thousand people from 68 countries was seen. It was found that on nights when the temperature went above 86 degrees Fahrenheit, people slept an average of 14 minutes less. This may sound like a small amount of time, but if calculated for the entire year, it amounts to about 44 hours of sleep loss. Doctors say that due to continuous less sleep, a person not only feels tired, but his ability to think and take right decisions also starts weakening. During hot nights, people start feeling irritability, restlessness and also have difficulty in concentrating.

body does not get rest

According to doctors, the body tries to cool itself at night, so that the fatigue of the day can be removed. But when the temperature at night remains high, the body does not get relief. Due to continuous sweating, there is a deficiency of water and essential salt in the body. This can increase problems like weakness, headache, dizziness and fatigue. Many people feel lethargic and restless as soon as they wake up in the morning, because their body is not able to rest properly throughout the night.

Increasingly hot nights are becoming a big threat to the world

A report by experts has revealed that due to climate change, night temperatures are increasing rapidly across the world. According to a report of the year 2024, about 2.4 billion people are facing such a situation where they have to face at least two weeks of hotter nights every year. It was told in the report that at many places the night temperature is reaching above 77 degrees Fahrenheit and this problem may increase further in the future. Doctors say that this is not a concern for the future, but has become the present reality, which is directly affecting people’s sleep, thinking ability and body health.

Who are most at risk?

According to doctors, small children, elderly, pregnant women and already sick people are most at risk. Elderly people sweat less, due to which their body is not able to cool down quickly. Children’s body loses water quickly. At the same time, for people who have heart, lung or kidney related diseases, hot nights can cause more problems. Laborers working outside and people who stay in the sun for long periods also need to be more careful.

You may have to take the heat of the night lightly

Doctors are advising that people should protect themselves not only from the daytime sunlight but also from the heat at night. Drink plenty of water before sleeping, wear light clothes and make arrangements for ventilation in the room. If the body does not get rest at night, then the effect of heat can gradually weaken the health. Therefore, now it has become necessary that people take the heat of the day as well as the night seriously.

According to the Meteorological Department, heat wave conditions may persist in many parts of Rajasthan, Uttar Pradesh, Madhya Pradesh, Punjab, Haryana, Chandigarh, Delhi, Chhattisgarh and Konkan-Goa till May 22.

The temperature in the western Himalayan regions may also increase by 3 to 4 degrees Celsius. Skymet Weather President Mahesh Palawat said that instead of eastern winds, now north-western winds are blowing, which are coming from central Pakistan and Rajasthan.

What is heatwave?

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.

Experts say that this is not just normal heat but a dangerous situation, which can prove fatal for children, elderly and people working outside.

Stroke Risk: The problems related to climate change are no longer limited to just environmental problems like melting of glaciers or rising sea level. This is having a deep impact on our health, especially our brain. From increasing heat to changing weather and pollution, they are now directly linked to serious diseases like stroke. Experts have warned that now the risk of stroke is not limited to food habits or lifestyle only, but it is also related to the air and temperature in which we live. It is also becoming one of the leading causes of death and disability worldwide.

Risk of stroke increases due to heat and dehydration

According to the report, extreme heat significantly increases the risk of stroke. In a new scientific statement from the World Stroke Organization published in the International Journal of Stroke, it has been told that the weather outside is now starting to affect the activities happening inside our brain. The reason for this is that when the temperature rises too much, water starts leaving the body rapidly, which leads to dehydration. Due to this, the blood becomes thick and the risk of blood clot formation increases, that is, the blood becomes thick and starts clotting, which can cause ischemic stroke. Apart from this, heat also puts pressure on the heart and blood vessels, which further increases the risk.

effect of suddenly changing weather

Often people think that this is happening due to heat, but in this situation, not only heat, but sudden changes in weather also affect the body. Rapid changes in temperature, humidity and air pressure can increase blood pressure, which becomes the main cause of stroke. On this, experts believe that when the body has to adapt itself to the changing weather again and again, it puts extra pressure on the heart and brain and the risk of stroke increases.

Danger of pollution and compound weather

After this, there are situations which experts call “combined events”, that is, a weather that brings many problems simultaneously. We are talking about increase in air pollution along with climate change. In such circumstances, these problems aggravate each other, causing greater impact on the body. Increasing air pollution with climate change also increases the risk of stroke. Vehicle emissions, factories and events caused by climate change such as forest fires and dust storms spread very small particles in the air which reach the blood through the lungs and damage the blood vessels, increasing the risk of blockage or bursting. More than 20 percent of stroke cases worldwide are believed to be related to pollution. Apart from this, when several weather conditions like heat and drought or cold and humidity come together, this danger increases further.

Which people are most affected and what are the solutions?

According to the report, this condition proves to be dangerous and sometimes fatal for the elderly, people working outside and those who are already weak or ill. Especially about 89 percent of stroke cases are seen in low-income countries, where the impact of climate is also greater, and they also have less resources to deal with it. Experts say that to reduce this threat, it is very important to reduce greenhouse gas emissions, adopt clean energy and make people aware. Besides, there is a need to prepare the health system for weather related risks.
