Why does my body emanate a lot of heat

The body can vary its body temperature depending on the climatic conditions to which it is subjected. Humidity is one of the main reasons that causes the thermal sensation increase in our body and, therefore, more heat is emitted. That is, when there is a lot of humidity in the environment, a thermal sensation is perceived greater than when the humidity decreases.

People who live in very humid climates, especially in coastal areas that exceed 35ºC, are more likely to have a greater sensation of heat, especially with temperatures approaching 40ºC. But,why the body emanates a lot of heat? With the sensation of humidity and extreme heat, the organism produces a greater loss of water and minerals, that is, a body dehydration occurs. This usually manifests itself through rise in body temperature or physically through feelings of fatigue, exhaustion, or cramps.

For this reason, excess heat can pose a risk to the health of older people, since their state is weaker. In addition, there are also other groups that can be more affected by excess heat, such as young children, women in the menopausal stage, people who suffer from obesity, people who suffer from heart or respiratory diseases, those who work exposed to the sun or those who exercise outdoors during hot hours. Remember that hydration is essential to withstand excessive heat and prevent your body from giving off a lot of heat.

To reduce excess heat in the body, our body has mechanisms that help it. The sweat It is one of them, since it helps to dissipate and regulate body temperature. However, the body sometimes is not able to eliminate all the excess heat that is in itself, which can alter the body. These cases are known as heat stroke or heatstroke, that is, unprotected exposure to high temperatures or the sun for a period of time. These two bodily alterations are the most serious and usually have some consequences for the body.

If the body exudes a lot of heat, it can be a direct consequence of suffering excessive heat of a certain climate. This excess or overexposure can cause heat to deposit in the body at high temperatures, which results in fatal consequences for the organism. Some of the most common disorders caused by excess heat are:

• Heatstroke: Also known as heat stroke, it is the consequence of the most serious excess of body heat, which is above 39.4 and 41ºC for 10 or 15 minutes. This situation can cause very serious damage to the body and in extreme situations, even death.
• Heat exhaustion: the body deposits heat, which can cause the loss of water and mineral salts, producing exhaustion or profound fatigue.
• Syncope: When you are subjected to high temperatures and the body collects all that heat, fainting can occur due to poor irrigation of the brain tissues. Syncope is common in older people and its risk is high since it can cause other injuries when hitting when falling. To avoid them, you have to drink large amounts of fluids and change your position, in addition to taking light walks and activating the body moderately.
• Sunburn: produced by long exposure to the sun, they manifest with red and burning skin, as well as with the appearance of blisters and even fever.
• Rash: Excessive heat can cause rashes, a type of dermatitis that results in pimples on the chest, neck, or joints. This is a direct consequence of the excessive sweating your body produces when it exudes heat.
• Cramps: leg and arm cramps are a consequence of the loss of mineral salts produced by excessive sweating when your body is subjected to high temperatures.

The human body is at a normal temperature of 36.5 or 37ºC roughly, since it easily oscillates around this temperature, which is completely normal. Generally, the temperature follows a circadian rhythmIn other words, it is lowest first thing in the morning and reaches its maximum level between 4 and 6 in the afternoon. In addition, you should know that the normal temperature level can also vary according to the time of year, as a result of the body’s adaptation to different climates, as well as varying from one person to another.

But how is body temperature regulated? The neuronal area located in the the anterior hypothalamus, which is responsible for regulating and balancing both the production and dissipation processes of body heat and does so through two different techniques:

• Increases or reduces the body’s production of heat through metabolic reactions and muscle activity.
• It starts up, or not, mechanisms for the conservation and / or dissipation of heat. That is, when the body temperature is high, the respiratory rate increases and the blood vessels dilates to be able to lose more heat during breathing and sweating is activated.

Likewise, the thermoregulatory center of the hypothalamus is responsible for sending signals to the brain so that the body can establish behaviors that help it avoid an excessive increase in body temperature and, in this way, avoid giving off a lot of heat. The acclimatization of the body to different climatic temperatures can take up to a week, during which time a greater amount of sweat is generated that will help our circulatory system to adapt to the increase in temperatures.
