Hot Effects On Our Body

By Wiki Healthier Staff


The human body is able to adjust its temperature and maintain it around 36ºC when the external heat is excessive, this mechanism begins to lose its effectiveness. Here are the effects of heat on our body.

The effects of heat on our body begin to be observed when the temperature self-regulation system ceases to be effective. If the error in the system designs, the heat can lead to life-threatening conditions.

Man has a thermoregulatory system programmed to maintain body temperature around 36°C, the temperature that allows normal performance of biological functions.

When the temperature balance is broken, for cold or for heat, undesirable effects and pathological symptoms appear. Hypothermia and hyperthermia can lead to death.

How does our body control the effects of heat?

The human body can rely on two main mechanisms to combat heat:

  • increased blood flow to the skin. Through vasodilation of the outermost areas, the body can exchange heat with the environment. This allows us to disperse heat and prevent damage to organs.
  • sweating Drops of sweat, evaporation, cause a cooling of the body. The sweat glands are capable of producing one and a half liters of sweat per hour.

When the external environment is too hot, above 35 degrees, sweating can start to be inefficient. If the fit system warns that fluid loss through sweat is putting you at risk of dehydration, it stops breathing.

It is at this point that the effects of heat on our body begin to appear. Let’s see what they are.

effects of heat on our body

bad breath

Dehydration, when present, involves all body tissues, including the oral mucosa. The mouth becomes dry due to lack of salivation. In the absence of saliva, bacteria multiply because one of our defense systems is loose.

It is precisely the bacterial proliferation that causes halitosis or a bad smell.

heat cramps

Through sweats, we not only lose fluids, but also the electrolytes and salts required for cellular functions. One of the tissues that needs a lot of salts is the muscles.

If the sweating is continuous, many electrolytes are lost and, therefore, it is possible to notice cramps or muscle spasms in the extremities. It is already an alarm signal: in case of cramps, physical activity should be stopped and rehydrated. The next step is physical exhaustion for the heat.

heat exhaustion

When not running to shelters, the loss of fluids and salts through sweating can lead to hot exhaustion, especially when the body suffers from physical exertion.

Symptoms of heat change are:

  • tachycardia
  • Irritability
  • Irritability
  • /li>
  • hypotension

solarization

It is a situation similar to heat exhaustion. The cause, in this case, is prolonged exposure to the sun.

Symptoms of sunlight are:

  • exhaust
  • nausea and vomiting
  • seats

Syncope

sycoperus can have different causes, one of them is heat. Extreme heat causes excessive vasodilation and redistribution of blood, a phenomenon that decreases blood flow to the brain.

Syncope is a consequence of the body’s inability to maintain adequate blood flow to the brain. A lower swelling of the blood means an insufficient amount of oxygen.

The central nervous system is forced to activate a regulatory mechanism. This mechanism consists of finding the horizontal position to improve blood flow to the brain. Therefore, the main symptom of syncope is fainting, which usually precedes blurred vision and dizziness.

Recovery is quick: as soon as the body is in a horizontal position, normal flow to the brain returns.

heat actiritis

It is one of the most serious effects of heat on the body. It can cause death and is considered a medical emergency.

The first symptoms are escape or sunstroke. If you don’t take short-term action, the situation worsens for heat stroke.

Up to 40 degrees Our body is capable of activating a series of defense mechanisms against heat. However, when it exceeds 41 degrees, these strategies start but more effective. The cells cannot work under these extreme conditions and multicorral dysfunction can occur.

Avoid the effects of heat on the body

To avoid the effects of heat, measurements are elementary and can prevent fatal consequences. Prevention consists of:

    Correct daily hydration.

  • Do not expose yourself to the sun without protection and for a long period of time.
  • suspend work activities and sports for the first symptoms of fatigue and cramps.
