The excessive heat of the body at night is a symptom of not working properly, especially in children and the elderly. For them, this condition could indicate a health risk. Generally, the body feels a greater thermal sensation when the humidity level is high. But what are the causes and consequences of body overheating at night?
The body can vary its temperature depending on the climatic conditions it is faced with. L ‘ moisture is one of the main reasons why the thermal sensation of our body increases. As a result, it gives off more heat. This means that when the humidity in the air increases, there is a greater thermal sensation than when it decreases.
People who live in very humid climates, especially in coastal areas that exceed 35 ° C, are more likely to feel hotter.
This is especially true with temperatures around 40 ° C. But why, then, does the body give off so much heat? With the sensation of humidity and extreme heat, the body undergoes a greater loss of water and minerals, that is to say, undergoes a phenomenon called dehydration. The latter can manifest itself through an increase in body temperature or, physically, with a feeling of fatigue, tiredness and cramps.
The above explains why the increase in body heat can be risky for the elderly, who are normally in a weaker state. There are also other categories of people who can suffer more from excessive heat, such as young children, women in menopause, those suffering from obesity, those suffering from heart or respiratory diseases, those who work exposed to sunlight or those who practice physical exercise in the open air during the hottest hours.
It is important to remember that hydration is essential to withstand excessive heat and prevent body temperature from rising.
To reduce excessive body heat, our body has mechanisms capable of solving the problem. One of them is sweat. This helps to dissipate and regulate body temperature. However, the body can sometimes not completely eliminate excess heat and undergoes alterations known as heat stroke or sunstroke. This happens after unprotected exposure to high temperatures or the sun for a certain period. These two types of alterations are among the most serious and normally have consequences for the body.
If the body gives off a lot of heat, this can be a direct consequence of exposure to excessive heat due to a certain climate. This excess, or overexposure, can cause heat to be deposited in the body at high temperatures with fatal consequences. Some of the more common changes caused by excessive heat are:
The human body is at a normal temperature of 36.5 ° C or 37 ° C approximately. But keep in mind that it undergoes normal variations around this value. Generally, the temperature follows a circadian rhythm. It means that it is lowest in the early morning and peaks between 4 and 6pm. Furthermore, the normal temperature can also vary according to the time of year as a consequence of the body’s adaptation to different climates. It can vary from one person to another.
But how is body temperature regulated at night? The thermoregulatory center is the neuronal area located in the anterior hypothalamus, which has the task of regulating and balancing both the production processes and those of dissipation of body heat through two distinct techniques:
The thermoregulatory center of the hypothalamus is responsible for sending signals to the brain. Thus, the organism reacts in such a way as to avoid the excessive increase in body temperature. As a result, avoid letting your body feel too hot. Acclimatization of the body to different temperatures can take up to a week. More sweat is produced during this time, which will help our circulatory system adapt to rising temperatures.
