Why is the heat of the air during the night so dangerous?

In the midst of a record-breaking heat wave, Phoenix, Arizona, one of the hottest cities in the world and under a record heat warning, set a remarkable record: overnight temperatures between Tuesday and Wednesday only dropped to about 36 degrees Celsius, setting a new record for the lowest overnight temperature.

to report Scientific AmericanToday, the world is witnessing a wave of intense and unprecedented heat. For example, this year, in the first week of July or mid-July, we saw the beginning of the hottest week and then the record of the hottest July in the history of the planet. Combustion of fossil fuels is the main cause of this year’s frequent and more intense heat wave and ultimately, the main reason for the increase in global temperature. Atmospheric phenomenon El Nino which we are facing this year will also increase the global temperature.

Intense and continuous heat is a great threat to the general health of the body. In the United States alone, heat is the number one killer of weather-related events. Heat has killed more people than all storms, tornadoes and floods. Heat causes the body to become dehydrated, thickening the blood and ultimately causing the heart to pump harder. The heart and other vital organs may suffer serious damage due to excessive exposure to heat.

The ever-increasing temperature is grabbing the headlines every day and it is definitely very worrying. When the air temperature rises above 30 degrees Celsius at night, the body doesn’t get a chance to cool down. The rise in temperature at night is very worrying, especially for houses without air conditioning and homeless people. Exposure to heat at night is a warning sign exclusively for younger people, the elderly, and people with underlying diseases and health conditions such as asthma and heart disease.

When the temperature is high during the night, the body suffers much more pressure and tension, and as the risk of heatstroke increases, the high air temperature becomes a threat to life and puts a person at risk of death.

heatstroke It is a relatively common reaction of the body to extreme heat and it includes symptoms such as dizziness, headache and low blood pressure. Heatstroke is usually treated by resting, staying in a cool environment, and drinking plenty of water. Heatstroke requires medical attention if it is severe, and is often accompanied by dry skin, body temperature rising to about 40 degrees Celsius, confusion and sometimes unconsciousness.
