The United States is in standard debris Heat waveWith tens of millions on alert. The continuous heat dome installs a lot of the Middle West and extends throughout the northeast. This phenomenon loses hot air and moisture, and it exacerbates the “feeling” temperature much higher than it is already.
Health experts and climate scientists have described the effects of severe heat on the human body, which the population is more likely to be risk and mitigating.
What is thermal stress and what causes it?
This happens when the body tested the accumulation of heat, at a level more than it can release. “The human body has this impressive ability to cool through the evaporation of sweat,” said UWE Reischl, a professor at Public Health and Population at Boys State University. But even when the body produces sweat, evaporation can be limited due to moisture in the air.
Another factor that causes the body temperature to increase when a person wears clothes that prevents sweat from release the skin. And when the body does not contain enough water, it becomes so dried that it is no longer able to produce sweat anymore.
How is it connected to the phenomenon of continuous heat dome?
Warm air is able to keep moisture more than cold air. “So, the more warm the dome of the heat and the levels of higher humidity,” said Rachel. Urban environments with many buildings, paved roads and parking lots exacerbate the possibility of heat stress, because they absorb heat from the sun (and release it) throughout the day.
What are some signs of heat stress?
“Thermal stress is a spectrum,” said Christie EBI, a professor of environmental and occupational health at Washington University. Symptoms can range from small red blisters on his hands to fainting. In extreme cases, if the body temperature rises above 103f (39C), this may lead to a hot blow, which can cause brain enlargement and other internal organs, and can be fatal.
Who is the most It was affected by heat stress?
Children, the elderly and pregnant women are among the most vulnerable to heat stress. EBI said: “Athletes and outdoor workers can be more likely to risk heat stress,” with more people or work move, the more heating their bodies. These conditions are more fraught with people like farm workers, who need to protect them from physical or chemical risks, such as pesticides. They must wear protective clothes, which can interfere with the ability of their bodies to evaporate sweat.
How do human bodies recover from heat stress?
“When we are exposed to high temperatures, we need time to calm our bodies, and it is usually the time at night when that happens,” said Ayb. (But since 1970, the summer temperatures have increased overnight 3f on averageThis means that people get less at night.)
“In addition to rest, the body needs moisturizing,” Richel said, adding that people should drink more water than they usually do.
What can people do to relieve heat stress?
Avoid arduous outdoor activities, drink fluid, stay away from the sun and spend more time in air -conditioned places such as cooling centers.
What are some ways to stay cold without AC?
Putting your feet in cold water, putting cold towels around your neck, sitting in front of an electric fan and filtering water on yourself effectively Ways to cool. The shadows also descend at home during the day and open windows at night.
