Heatwave: How does a heat wave affect our body?
According to an advisory issued by the Meteorological Department on March 14, daytime temperatures in North Balochistan, Upper Sindh, South Punjab, Kashmir and adjoining areas are likely to be 9 to 10 degrees Celsius higher than normal while the capital Islam Daytime temperatures are expected to be seven to eight degrees Celsius higher in Abad, Upper and Central Punjab, Khyber Pakhtunkhwa, Gilgit-Baltistan, Lower Sindh and South Balochistan.
To avoid heatwave, citizens should avoid going out unnecessarily and take precautionary measures against sunlight.Excessive water consumption is also essential during this time. According to him, this time the intensity of heat has been increasing since the month of March, which suggests that this time the duration of summer may take longer.
There is a possibility of some relief in the heat wave after March 20.The main reason for the sudden rise in temperature is climate change.
Pakistan adheres to the 2015 Paris Agreement on Climate Change, which requires all countries to reduce their greenhouse gas emissions. According to him, Pakistan has set a target of 50% reduction by 2030. According to him, in order to reduce global warming, all countries have reconsidered their goals in the COP 26 conference.
what is dangerous effect of heatwave on your body?
Whether we are in a blizzard or in a heat wave, our body tries to maintain a temperature of 37.5 degrees Celsius. This is the temperature at which our body has learned to work.
But as the mercury rises, the body has a hard time keeping its core temperature low. In these cases, our body opens the arteries near the skin so that we can sweat and lower our body temperature.Sweat dries out and dramatically increases the heat released from the skin. This process sounds simple, but it puts a lot of pressure on the body, that is, the higher the temperature, the higher the pressure on the body.
These open arteries lower blood pressure and our heart has to work harder to get blood to the body. Inflammation of the open arteries can cause swelling in the feet and itching on the scalp.But if the blood pressure drops significantly, less blood will reach the organs of the body that need it the most and the risk of heart attack will increase.
Healthy people can use common sense to protect themselves from the heat wave, but some people are more likely to get heatstroke. It can be difficult for older people or people with diseases such as heart disease to cope with the pressure exerted on the body by the heat.
Diabetes 1 and 2 cause the body to become dehydrated rapidly and the disease can affect the ability to produce arteries and sweat.It is also important that you understand that your body temperature has risen too much and that you should do something about it. We don't take this very seriously, but children and people with mental illness may be more vulnerable to heat waves.
Homeless people will feel the heat of the sun more and people living at the top of the flat will also face higher temperatures.Can certain medications be harmful during this time?Yes! However, people need to take their medication as usual and try to keep their body temperature to a minimum and drink as much water as possible.
Diuretics, also known as 'water pulses', increase the body's excretion of water. They are used by people with heart disease. At high temperatures, these drugs can lead to dehydration and poor mineral balance.
Antihypertensive drugs that lower blood pressure connect the blood vessels that swell to withstand the heat and cause a dangerous drop in blood pressure.
How to keep the body cool?
Make sure you drink plenty of water or milk. There is nothing wrong with drinking tea or coffee. However, avoid drinking too much alcohol as it can increase the risk of sudden dehydration.If the heat outside your home is higher than the heat inside the house, it is best to keep your windows and curtains closed.
