How does a person die due to heat?
Of course, every living being has to taste death, and everything has to be mortal. Various countries of the world, including Pakistan and India, are in the grip of extreme heat these days. Somewhere the temperature is constantly rising and people are dying due to hubris. The effects of an increase in temperature also affect the human body, where an increase of a few degrees starts a battle of life and death inside the human body.
How does a person die due to a heat wave? What is the effect of heat on the organs of the human body? To find out, experts conducted some experiments by putting volunteers through 'hot boxes'.
Through this process, volunteers are placed in a heated box and their body's response to different temperatures is evaluated.
Experts say that in the light of experiments, it has come out that the temperature is considered to be a danger to the human body. A temperature several degrees lower than this can be dangerous for the human body.
A healthy human body temperature is 98.6 degrees Fahrenheit, which is only seven degrees Fahrenheit lower than the complications caused by heat stroke, says Ollie Jay, an expert in heat and health at the University of Sydney in Australia.
Anyone who develops a fever of 102 or higher during heat waves without an infection can develop heat exhaustion and heat stroke, says Dr. Neal Gandhi, MD, director of medicine at Houston Methodist Hospital.
He said that most patients can have a fever of 104 or 105 during a severe heat wave. If the temperature of the patient's body is one or three degrees higher than this, there is a risk of death.
How
does heat kill?
Professor Ollie Jay says there are three causes of heat-related deaths, the first leading cause being heat stroke. In such a case, the body temperature increases very much and the organs stop working.
According to him, when the internal temperature
of the body increases too much, the body sends the blood flow to the skin to
cool down. During this time, the supply of oxygen and blood to the stomach and
intestines decreases and the irregular substances are moved due to the
digestive system being affected.
Professor Ollie Jay says that these factors have many adverse effects on the body, including blood clotting and organ failure, which can lead to death.
Pressure
on the heart.
Most of the deaths due to heat are due to the pressure on the heart. People who already have heart disease are particularly affected.
In this situation also the same process takes place again i.e. the body sends blood to the skin to keep itself cool, due to which the blood pressure decreases. Meanwhile, the heart has to work harder to pump blood.
Dehydration.
According to Prof. Ole J, the third reason is to be severely dehydrated. When people get tired in the heat, the body loses a lot of water, which puts stress on the kidneys.
Dr. Neil Gandhi says that in such a situation, many people have no idea of the nature of the danger.
Dr. Renee Salas, professor of public health at Harvard University, says that dehydration can cause a person's condition to deteriorate due to lack of water. Organs stop working due to lack of blood, oxygen, and nutrients, which can lead to seizures and death.
According to him, dehydration is dangerous for everyone. But it increases the risk level for people who already have a disease and are taking medication.
How
can the brain be affected?
Many medical experts say that heat intensity can also affect the human brain. This makes a person confused and his ability to think and understand is also affected.
Chris Abbey, a professor of public health and climate science at the University of Washington, says the first symptom of a heat wave patient is confusion. But the affected person does not realize this because it is a big problem for the elderly.
W. Larry Kenney, professor of physiology at Pennsylvania State University, says that if a person has a fever of 104 and their nervous system is not functioning, that is the main symptom of heat stroke.
Humidity
ratio in air.
Some experts also use a more complex method of measuring outdoor temperature and humidity in the air called wet bulb globe temperature (WBGT) to determine heat stroke.
Apart from temperature and humidity ratio, WBGT also reports on other aspects.
Professor Kenny says that according to this method, even if the body temperature is 35 degrees Celsius, the body can suffer from problems.
Professor Kenny has also set up a hot box lab where he has so far conducted experiments on 600 volunteers.
He says that when experiments were conducted on volunteers using the WBGT method, young volunteers could tolerate temperatures up to 30.5 degrees Celsius, while older ones could only tolerate temperatures up to 28 degrees Celsius.
Similarly, when experiments were done to tolerate dry heat, the young could tolerate up to 52 degrees Celsius while the older ones could tolerate up to 43 degrees Celsius.
According to him, heat with moisture in the air causes more deaths than dry heat.
How
to keep the patient cool?
Dr. Renee Salas says that heat stroke is an emergency and medical personnel try to cool the patient's body within 30 minutes.
According to him, the patient is also kept in a tub of cold water to keep him cool. But these bathtubs are not available everywhere. So the medical staff also apply drops to normalize the temperature of the patients. Ice packs are placed near the patient.
Sometimes even this method doesn't work, says Dr. Renee Salas.
They say death by heatstroke is like a silent killer. Because there are no dramatic situations in watching it. It's all hidden.
