Initiate National Heat Health Information System (NIHIS) and also pain.gov On July 26, 2022, the Biden administration cited heat waves and global warming as a serious health threat. As the new initiative promises a “scientific answer” to hot weather, five articles from the Archives of the Conversation reveal what researchers know about heat and health.

1. It is painful

Heat waves can be dangerous in different ways, it is written William Calvinwho teaches mathematics and neuroscience at the University of Washington.

“Hyperthermia can be killed by dehydration caused by heavy sweating; changes in sodium and potassium in the blood confuse the heart and nerve cells, so breathing or heartbeat can stop suddenly,” he wrote.

Calvin explained that human body they did not evolve to hold extreme heat with pain. “Normally, sweat comes off your skin and you get cold. But with great pain, the air is already saturated with water vapor, so the cooling of the air stops. However, you continue to sweat anyway, and you are at risk of dehydration.”

2. Low resistance to higher current

“This combination of body temperature and heat at which a person’s core temperature begins to rise is called the ‘critical environmental threshold,'” said a team of Penn State University researchers researching heat health: W. Larry Kenney, Daniel Vecellio, Rachel Cottle same to you S. Tony Wolf.

In a rare test of the human body’s heat tolerance, researchers have found that the limit is lower than previously thought. When the air temperature reaches 100 degrees Fahrenheit (38 Celsius), people can start to feel sick at only 60% humidity – a higher temperature and lower humidity than researchers determined in 2010.

“More than those limits, actually body temperature rises the risk of heat-related illnesses continues to increase with long-term exposure,” they wrote.

3. Age factors

Very painful or dangerous especially for those over 70, according to the family doctor Dr. Gabriel Nealwho teaches at the Texas A&M College of Medicine.

In his story of escape pulseNeal explains the factors that make the elderly more susceptible to chronic diseases.

“As people age, our body’s ability to keep cold decreases, and older people often take medications that further impair this ability,” Neal wrote. “Additionally, seniors may not be aware of dangerous temperatures and may not have air conditioning in their home, and may not have someone to check on them.”

4. Wet or dry, heat is heat

It’s hot and humid, says Mississippi State University exercise physiologist John Eric Smith.

“The hot desert environment is very stressful because of the high temperature, while the hot climate is stressful because the body has a problem to get rid of the heat when the sweat does not come out quickly,” he said.

Smith added that how heat and humidity affect people depends on things like the weather where they are, and cooling system in houses and buildings.

5. heating food

Tufts University Pathologist Elena Naumova warns that maintaining a healthy diet is becoming more of a challenge in some temperature. “This is because the warm, humid climate encourages bacterial growth,” she wrote.

Naumova mentioned several factors related to the environment in the spread of foodborne diseases. “The problem that arises is that heat wavesforest fires and severe storm they attract more power outageswhich in turn affects food storage systems and food processing operations in stores, production and distribution facilities and households,” she wrote.


Our lab has gotten hotter and hotter getting dangerous faster than many people realize
