Thermal sensation is associated with the body's reaction to environmental conditions.
Thermal is a notion with several uses. As an adjective (thermal or thermal), it refers to that linked to temperature or heat . In this sense, we can speak of thermal sensation to refer to how the human body reacts to various environmental conditions.
The idea of thermal sensation , in this way, transcends air temperature, since in the body we also experience the effects of other variables when it comes to feeling whether it is hot or cold. Air speed and humidity are other issues considered when measuring thermal sensation. In this way, in a place where a temperature of 26º C is recorded, there may be a thermal sensation of 32º C , for example.
A thermal material is one that can maintain temperature . A thermal glass, therefore, can keep its contents hot for an extended period of time. If a person pours hot coffee into a thermal glass, they will be able to drink it for a long time afterward without the temperature of the liquid having dropped.
thermal fever
Thermal fever , on the other hand, appears when a body is exposed to a very high outside temperature. If a subject remains under the sun for several hours on an afternoon with a temperature above 40º C , he or she may suffer from thermal fever. Other names by which this disorder can be found are thermal hyperpyrexia, heat stroke, heatstroke and syriasis .
It is important to note that thermal fever can cause seizures, leave a person in a coma, or even cause death. Regarding the causes of this disorder, in addition to exposure to a very high temperature for a long time, poor air circulation and excessive physical exercise can also play a role. The individuals most likely to suffer from it are those who are experiencing general illnesses and those who are over 40 years of age.
A thermal key can interrupt the electrical current if a certain value is exceeded in the circuit.
Common symptoms
The symptoms associated with thermal fever are many, although all of them are easy to detect, unless the attack begins suddenly; Let's look at some of them below:
* headache, nausea, chest pain (in the area below the left nipple) and weakness;
* cessation or decrease in sweating , something that can occur up to several hours before the attack;
* dry and hot skin, plus congestion;
* presence of cramps or muscle twitching;
* anguish and indifference to the environment;
* contraction of the pupils, followed by dilation;
* decreased tendon reflexes;
* pulse rate above 159 and slight elevation in blood pressure .
Diagnosis and treatment of thermal fever
For a doctor to diagnose a suspected heat hyperpyrexia , it is necessary that the patient presents pyrexia without any apparent cause beyond the aforementioned exposure to a very high temperature. Once thermal fever is detected, treatment should begin as soon as possible, although this is difficult given that it shares some of its symptoms with pneumonia, malaria and meningitis.
Some of the easy measures to take to combat a case of thermal fever are water baths at very low temperatures. If this is not possible, or in addition, it is advisable to wrap the patient with a wet blanket and massage the skin to promote a decrease in body temperature .
Other uses of the term
A thermal column , sometimes referred to simply as thermal or thermal , is the column of air moving upward from a low atmospheric altitude. These columns are formed from the phenomenon of convection.
Finally, a thermal key , which can also be mentioned as thermal , is a device that interrupts electrical current when it exceeds a certain value in a circuit .
