Human -based climate change has already made heat waves in the world more often and intense.
Scientists examining the role of global warming on the weather, today, each heat wave carries fingerprints of the climate crisis, he says.
First of all, the climate change directed by people burning fossil fuels in general makes global excessive air in general, but most of this change is related to heat.
In the United States, Heat kills more Americans than any other disaster -related disasters, and will continue to worsen as the world warms up from burning fossil fuels.
Here is the extreme heat of your body, you need to pay attention and how to remain safe.
What happens to your body
Normally, your body is usually used between a certain temperature range, usually between 97 to 99 degrees Fahrenheit. Boston Medical Center Department of Emergency Medicine and Boston University Faculty of Medicine Emergency Medicine Department of Dr. According to Judith Line, when your brain detects a change – lower or higher than that – tries to help your body cool down or warm up.
“There are several different ways he tries to cool the body. In some way, the most common way we think is your sweating,” he said. “Pores open, the body sweat and sweat evaporates, this body cools.”
The second way for your body to cool itself is to dilate the vessels and raise your heart rate, which helps to bring heat and blood to the surface of your body and helps release excess heat.
When you are exposed to high temperatures, it becomes difficult for your body to continue to cool. And if your environment is hot And Humid, sweat does not evaporate easily – this increases the temperature of your body even more, Mayo clinic.
“The higher the moisture, the higher the temperatures you need for excessive heat,” he said.
High body temperatures can damage the brain and other vital organs, Hkm says. They may also cause several heat -related diseases.
Including light heat -related diseases Heat cramps, The most common one, Linden said Linden. Heat cramps may develop in people who sweat, including also during exercise. Excessive sweating uses the entire salt and moisture of the body and usually can cause muscle pain or spasms in the abdomen, arms or legs, CDC.
A rash Can also develop. CDC, this, in hot and humid weather caused by too much sweating skin irritation and most common in young children, he says. It is usually a red acne or bubble cluster and tends to be in places in the neck, upper chest or elbow wrinkles.
When your body begins to overcome the ability to cool himself, Heat depletion.
Linden said, “In this case, you will see excessive sweating because your body will really keep up with this extra heat. You will feel light -headed, you can be dizzy, nausea, headache and skin often look pale and damp, and the pulse often looks fast.”
“This is the attempt to cool the body before entering a irreversible point.”
A heat stroke It is the most serious heat -related disease and may cause death if left untreated.
“The temperature of your body rises above 104 to 105 degrees, and where your mechanisms are starting to fail.” He said.
According to CDC, the warning signs may include extremely high body temperatures, red and dry skin, fast pulse, headache, dizziness, nausea or loss of consciousness.
Line said that the distinctive feature of a heat kick was confusion and agitation.
“So when someone is in the heat and when they are confused and uneasy, this is heat stroke until it is proved otherwise, and you need to call 911 or get help immediately and remove the person from heat.”
The elderly, people with chronic medical conditions and children are at a higher risk for severe diseases.
The elderly and people with chronic medical conditions may be lower than the perception and responding temperature changes and may be taking medications that worse the heat effects, Hkm in question.
“Very young (people), because the possibility of recognizing the disease is lower, and if they begin to overheat, Linden said.
Authorized, student athletes and pets are also at a higher risk, he added.
“You should never leave a child or a pet for a minute, Linden added Linden, Linden added.
When your community encounters extreme temperature, there are a few things you can do to keep yourself and others safe.
First, consider the symptoms of heat depletion or other diseases. “If someone starts to feel light -headed, dizzying, nausea or headache, Linden said Linden, Linden said Linden. “This means to take them from heat and a cool environment.”
Putting water on someone who lives and gives them liquid can help to cool them. If someone starts to lose consciousness or if there is nausea or vomiting, call 911.
“If you see any of the confusion, this is a red flag,” Line added Linden.
When it is hot outside, according to Line, try to avoid open -air activities – especially between 11:00 and 15:00. If you need to go out, wear light -colored clothes, cover your head and drink plenty of fluids.
Don’t wait until you get thirsty for drinking water – this can be a sign of dehydration. Linden recommends you to drink at least one glass of water – or more – one hour.
“If you start to feel light -headed, dizzying, sweating, fast pulse, Linden said Linden, Linden said Linden.
Try to find places where you can stay cool in your air conditioner or region, Ready.gov. Even spending a few hours in a shopping center or public library can help.
When you are at home, fans can help, but do not trust them as the only way to cool them-even though they feel comfortable, they do not help prevent heat-related disease.
“If you are in a super warm room, if you have a fan, is it useful? No. I think, if you have a fan and your straw… Then fans can help,” he said. “Fans are not perfect.”
Finally, make sure you control your neighbors, parents and friends – especially older individuals living alone or isolated, Linden said Linden.
