The coldest is not the lowest temperature, but this time!

An incredible but very real thing: there is a time when you will feel it is the coldest, shivering, though not the lowest temperature in winter. Why?

Our usual thinking is that the lower the temperature, the more cold we feel. However, there is the fact that the time when the body feels the coldest is not necessarily coinciding with the time when the sky fell to the deepest temperature.

Mechanism of the body

Temperature is a major factor affecting cellular reactions, biochemistry and enzymes, so to adapt to temperature changes to survive, our bodies must be reasonable to regulate body temperature. Optimal.

Regulating body temperature.(Source: Youtube / Sciencehook.com).

First or foremost on human body temperature, including central temperature (temperature of organs deep inside the body such as viscera, brain .) and peripheral temperature or body part (includes skin and subcutaneous organizations).

If the central part temperature is always stable in the range of 36.5 - 37 degrees C, the peripheral temperature is much more flexible, there is a change in every position on the body and it is easy to work. dynamic of outside temperature.

For example: When the room temperature is 24 to 25 degrees Celsius, the skin temperature in the head, chest, abdomen is 35 degrees C, and the hands and feet may be much lower (29 degrees C).

When the ambient temperature changes suddenly, the peripheral temperature will be greatly affected because it is the direct part of the environment, for example, you are in the background of warm heat but the temperature suddenly drops, the body will react by shivering, chilling, goosebumps and chills.

If this process is too sudden and your body is not good enough to handle it, there will be a very dangerous "heat shock" , even a life-threatening stroke.

Wearing warmth is a way to protect your body from heat shock and diseases when it gets cold.(Photo Plus Plus).

The moment the body feels the coldest

If your body is in good health, your body will be able to "defend" you before this sudden temperature attack with a thermostat, but when you regulate the temperature , you will feel very cold, even shaking. I was busy because my body could not produce the temperature yet.

This process will take place for a short time, this is the time you will feel the coldest (two teeth hit each other, chills, goose bumps .).

But after a while you will find your body getting warmer as your body starts to heat up to maintain a standard point temperature of 37 degrees C. Specifically, this process is based on the feedback of the nervous system. as follows:

1. Visual pre-diagonal neurons - preceding hills have many hot-sensitive neurons and some cold-sensitive neurons acting as thermal sensors to control body temperature will be stimulated too heat generator.
2. Heat receptors on the skin and organs are stimulated to provide protection mechanisms such as goose bumps to block pores, prevent heat loss and prevent outside temperatures from going into the subcutaneous organ layer.
3. The following hypothalamus - Integrating the received signals from the peripheral organs and the central heat signals from the pre-visual area of ​​the cross - the front of the hill to provide "countermeasures" to regulate body temperature, leaving the word It sends signals to the organs in the body.
4. Response mechanisms will occur when these agencies receive a protective "command" such as a vasoconstrictor that reduces the amount of heat carried from the body's center to the skin, reducing heat emission or bumps or windpipe to protect the steaming organ from cold air.
5. Next is the process of hyperthermia by trembling muscles, now we will feel the chills with continuous twitching muscles, muscle tremors will create a mechanical temperature that warms the body. The process of chemical heat generation will take place immediately after increasing the rate of cell metabolism, increasing heart rate.

The body will have a protective mechanism to maintain a constant temperature before the temperature fluctuation of the environment.(Photo Experiencelife).

As a result, after the shivering cold you suddenly feel warm, it is time for your body to begin to adapt to the changing temperature of the environment.

Then even if the temperature is lower, the body can still regulate properly to maintain the "warmth" for the body and we no longer feel the chill as when the body has not yet adjusted.

That's why people in cold areas below 0 degrees Celsius feel "hot" when temperatures rise at 1 or 2 degrees Celsius because the body has a proper adaptation.

Besides the body's protection mechanism, physical training, exercise or eating, keeping warm . will also contribute to protecting your health in cold days.
