The climate change that a person has already caused heat waves all over the world has made more frequent and intense.
Scientists who study the role of global warming on the weather say that every heat wave today carries the fingerprints of the climate crisis.
The climate change, which is driven by humans who burn fossil fuels, gets worse in general, but much of this change is linked to heat.
In the United States, Heet kills more Americans than any other weather related to a weather, and will only continue to exacerbate the world’s temperature rising from burning fossil fuels.
Here is what happens to your body at a very heat, what you need to pay attention to and how to stay safe.
What happens to your body
Usually, your body is used in a certain set of temperatures, usually between 97 to 99 degrees Fahrenheit. When your mind feels a change – either less or higher than that – it tries to help your body calm or heat, according to Dr. Godth Linden, Vice -head of the Department of Emergency Medicine at Boston Medical Center and a professor in the Department of Emergency Medicine at the Boston University College of Medicine.
“There are a number of different methods in which the (brain) is trying to cool the body.” Pores are open, sweating the body and evaporation of sweat, which cools the body, “said Linden.
The second way in which your body cools by expanding the vessels and increasing the heart rate, which helps to bring the heat and blood to the surface of your body and helps in the versions of this extra heat.
When you are exposed to high temperatures, it becomes difficult for your body to try to keep up with the cooling itself. And if your environment is hot and Wet, sweat does not evaporate easily – which drives the body temperature upward, according to May clinic.
“The higher the humidity, the lower temperatures you need for extreme heat,” said Linden.
High temperatures in the body can damage brain and other vital organs, CDC He says. It can also lead to many heat -related diseases.
Diseases associated with moderate heat, including Heat spasms, Linden said the most common. Heat cramps can develop in people who sweat a lot, including during exercise. Excessive sweating uses all the salt and moisture of the body and can lead to muscle pain or cramps, usually in the abdomen, arms or legs Disease Control Center.
A rash It can also be developed. This is the irritation of the skin due to a lot of sweating in hot and wet weather, which is the most common in young children, says the Center for Disease Control. It is usually a red group of pimples or blisters, and tends to be in places including the neck, upper chest, or in the elbow wrinkles.
When your body begins to overcome its ability to cool itself, you can develop what is known Heat exhausting.
“In this case, you will see excessive sweating because your body will really try to keep up with this additional heat.
“This is the last attempt of the body to cool itself before it really goes to the point of no return.”
Heat It is the most dangerous disease -related disease, and if left without treatment, it can lead to death.
“This is the place where your body temperature exceeds 104 to 105 degrees or so, and this is where your mechanisms began to fail,” said Linden.
Signs of warning may include very high temperatures in the body, red and dry skin, fast pulse, headache, dizziness, nausea or consciousness, according to the Center for Disease Control.
Linden said the characteristic of the stroke is confusion and incitement.
“So when someone is in the heat and they become confused and turbulent, this is a thermal blow to prove otherwise and you need to call the number 911 for that, or to get help immediately and get the person out of the heat.”
The elderly and people with chronic medical conditions as well as children are at greater risk of severe heat -related diseases.
It may be likely to feel the elderly and people with chronic medical conditions in response to temperature changes and they may take medications that increase the worst heat effects, CDC He said.
Linden said: “Very young (people) too, because they are less likely to recognize the heat -related disease and less likely to get out of heat if they start feeling comfortable,” said Linden.
She added that sports students and pets are at greater risk.
“In this weather, you should never leave a child or a pet in the car for one minute,” Linden added.
When your community faces intense heat, there are many things that you can do to keep the safety of others and others.
First, symptoms of heat depletion or other diseases are anticipated. “If someone begins to feel a light head, dizzy, nausea, or headache, this is the time to act immediately,” said Linden. “This means taking them out of heat and to a cold environment.”
Putting water on a person who may suffer from symptoms and giving them fluid can help cool them. If someone begins to lose consciousness or suffer from nausea or vomiting, call 911.
“If you see anyone who has any kind of confusion, this is an immediate red sign,” Linden added.
When the weather is hot outside, try to avoid outdoor activities – especially between 11 am and 3 pm, according to Linden. If you have to go out, wear light -colored clothes, cover your head and drink a lot of fluids.
Do not wait for a thirst for water to drink – as this can be a sign of dehydration. Linden recommends drinking at least one cup of water – or more – an hour.
“If you start feeling light, dizzy, sweating, and rapid pulse, then he comes out of the heat immediately,” said Linden.
Try to find air conditioning, or places in your area where you can go to stay calm, according to ready. Even spending a few hours in a commercial center or a public library can help.
When you are at home, fans can help, but do not rely on them as your only cooling method-while it may feel more comfortable, they will not help prevent thermal-related disease.
“If you are in a very hot room, if you have got a fan, is this useful?” Said Linden.
Finally, make sure that you are checking your neighbors, parents and friends – especially the older individuals who may live alone or isolated, Linden said.
