Answer India is burning like a hot furnace at this time. Especially in some districts of Rajasthan, the temperature has gone above 50 degrees Celsius. According to the Meteorological Department, Phalodi in Rajasthan is currently the hottest city in the state. The temperature here remains around 50 degrees. Not only in Rajasthan, heat has started showing its colors in Haryana, Delhi, Uttar Pradesh, Bihar, Madhya Pradesh and Chhattisgarh as well. Many states have come under the grip of heat wave. The Meteorological Department has issued an alert. These conditions create a situation of wet bulb temperature.
What is wet-bulb temperature
35 degrees Celsius is considered the highest wet bulb temperature for humans. If the temperature goes above this, then the sweat in the body has difficulty in evaporating. Due to the inability to evaporate, the body temperature starts increasing. This leads to hyperthermia. This is a condition in which the body absorbs or produces more heat than it can release. The body loses heat faster than it can produce it. This is a medical emergency in which the body temperature drops dangerously. Wet-bulb temperature is the limit of heat and humidity beyond which humans cannot bear high temperatures. Climate scientist Schneider said, “This is really a difficult situation to survive. You can die just sitting there.”

Where did this name come from
Where did the name wet-bulb temperature come from? For example, there has been record heat for the past several days. In such a situation, the mercury goes up a lot. When the heat is so much that a normal thermometer does not work to measure it. This is the reason why a special wet bulb thermometer is used. It contains mercury, but it is covered with a wet cloth. Usually a muslin cloth is taken and it is dipped in a vessel filled with cold water. The temperature taken from this indicates the humidity in the air. On this basis, it is easy to decide what to keep your routine or for whom it can be dangerous. Climate studies have shown that as the global temperature rises, hot air will be able to hold more moisture. As a result, humidity will increase and wet-bulb temperature will increase.

Without significant interventions to reduce greenhouse gas emissions and slow the pace of climate change, oppressive and dangerous heat will continue, said Friedrich Otto, a meteorologist at Imperial College London. He said, “We have seen everywhere around the world that heat records are being broken every year and this is exactly what we expect in a warming climate. Climate change has been a real game-changer when it comes to heat.” Friedrich Otto said that the situation is not good for those who spend a lot of time in the sun for any reason. It is like a big danger. Or rather, it is deadly.
