On July 1st, the fourth heat wave In Mexico, a prolonged period of warm environments that has generated temperatures above 30 degrees Celsius throughout the country, in general, while in northern states the thermometers have marked up to 45 degrees Celsius or even more. Although we know that this type of atmospheric phenomenon can cause dehydration in people, it is important to know what it can cause in the body and thus be alert to any eventuality.
Since the start of the third and fourth heat wave In Mexican territory, several states have been on alert due to high temperatures, which has led to preventive measures to avoid heat stroke that could put the health of the population at risk.
the effects of a heat Excessive symptoms range from dizziness and constant thirst to heatstroke and disorientation. However, when we talk about the consequences that the human body can have in the presence of a heat wavethese are usually more and of greater intensity, hence the importance of staying in places or spaces where there is shade or where the direct rays of the sun do not affect us.
What causes a heat wave in the human body?
although one heat wave causes severe damage to health, these and their magnitude will depend on the time of exposure to high temperatures, as well as direct sunlight, the intensity and duration of the thermal event, and even the infrastructure that exists in the space where we meet.
However, there are direct effects or consequences on people’s health, so experiencing a heat wavelike the one we are currently experiencing in Mexico, can to provoke the next thing in the body:
- Low blood pressure: this occurs because the blood vessels dilate and the heart works harder to push blood throughout the body, even causing rashes and swollen feet.
- Dehydration: It happens due to excessive and constant loss of fluids and salt from the body.
- Syncope: that is, the sudden loss of consciousness.
- Cramps and dizziness.
- Headache, irritability and exhaustion.
- And if the blood pressure drops too fast it could cause a heart attack.
- Heat stroke, which in turn leads to delusions, confusion or loss of consciousness, and in some cases seizures.
You may be wondering why all this is happening to the body when exposed for a long time to high temperatures, and more specifically to a heat wave. The fact that it has these reactions or effects is due to the fact that our body usually works or functions at an average internal temperature of 37ºC, whether we are in the midst of intense cold or strong heat.
But, as the temperature increases drastically, the human body has to work harder to maintain an adequate internal temperature, causing us to start sweating excessively and begin to experience one or several symptoms that we listed above.
In this fourth heat wave Try to stay well hydrated and stay out of direct sunlight. If you feel discomfort that could indicate that you have heat stroke or something similar, see your doctor and seek to cool down to keep your body temperature at a good level.
