Heat Impact: Who Is Most Susceptible?

Heat impact: who is most vulnerable?

High temperatures can take its toll on anyone. However, some are much more susceptible to the effects of heat than others. Learn more about high-risk groups and see what you can do to protect yourself from the heat.

Some people are much more sensitive to the effects of heat than others. This may be due to their body type or health problems. These members of the population must take great care to protect the body from the sun in the summer.

Of course, each of us must provide basic protection against the heat. For example, we should wear appropriate clothes, stay hydrated, and avoid the sun during the warmest moments of the day. However, those who are more sensitive to the effects of heat should maximize their efforts.

People who are most sensitive to the effects of heat are:

  • Children under 5 years of age,
  • People over 65,
  • People suffering from chronic diseases,
  • People who exercise or work outdoors.

People who are most sensitive to the effects of heat

Children are quite susceptible to the effects of heat

Children, especially the youngest ones, are very exposed to the effects of heat. This is because younger organisms lose fluid faster. Thus, they dehydrate faster. In addition, children warm up faster due to their small size.

That’s why you need to protect them from direct sunlight when the temperature rises, and watch out for signs of fatigue when exercising.

Seniors

Another group that is very susceptible to the effects of heat are the elderly. This is because the heat regulation center is in the hypothalamus, the part of the brain that regulates the body’s internal temperature. Unfortunately, its operation becomes slower with age.

Also, members of this group do not feel thirsty as much as they used to. This is why they are more likely to become dehydrated. Therefore, it is a good idea to remind them to drink the right amount of fluids from time to time.

In addition, older people sweat less than younger people. Therefore, their body temperature rises. If, in turn, they are additionally in a humid environment that increases sweating, their risk of heat stroke increases.

People with hypertension

Excessive heat constricts arteries and leads to dehydration. Both of these factors negatively affect people suffering from hypertension. Therefore, you should consult your doctor for advice on taking medications in hot weather.

Blood pressure drops at hot temperatures. This translates into changes in the action of drugs taken in standard doses. It is for this reason that you need to see a doctor for a checkup to protect yourself from unpleasant surprises.

Patients suffering from cardiovascular diseases and obesity

High temperatures also affect the functioning of the circulatory system. Of course, their effect is much stronger in people who have previously had problems with the cardiovascular system. This is because heart disease reduces the body’s ability to cool itself.

You can see for yourself how easily overheating can happen. Additionally, patients with heart disease often use dehydrating drugs to get rid of water from the body, which reduces their ability to sweat. This is why they are more prone to dehydration.

Obese person susceptible to the effects of heat

Obese people also have problems with cooling the body. Usually when it’s very warm they sweat profusely. This leads to a large amount of fluid and mineral loss, which often translates into dehydration.

In addition, they have higher amounts of adipose tissue, which changes the temperature regulation processes. Thus, they are more prone to heat stroke.

Athletes and outdoor workers

At the very end, we would like to mention people who are physically active outside. They are much more susceptible to the effects of heat. Direct exposure to the sun will increase the effects of high temperatures. Both sun exposure and exercise increase the risk of dehydration.

People from each of these groups must take care of appropriate protection, and if possible, they should limit their activities to hours when the sun is not so bright. In addition, you should always drink at least twice as much fluids as usual.
