How will the body change when the temperature drops to 10 degrees Celsius?

These are things that will happen to your body when faced with the coldness of the person outside.

The temperature may drop to 11-14 degrees Celsius, there are places below 10 degrees Celsius. It gets cold, and the heat level drops sharply, which can make us change both physically and mentally. But what happens when the body faces cold weather below 10 degrees Celsius?

first.

It gets cold, the air will be drier, the humidity is low - only about 40-50%. This air will stimulate the nerves inside the nose. The nose is required to send signals to the brain to increase the moisture in the nasal cavity.

At this time, the brain will signal to increase blood flow to the nose, allowing blood vessels around the nose to expand and warm the air through.

The nose is also ordered to produce more fluid (through the salivary glands) to provide more moisture for the air to pass through. Cold and dry air stimulates the immune system cells (mast cells) in the nose. When stimulated, the cells produce fluid in the nose or nose to moisten the air.

The nasal mucus cannot absorb all the moisture, so our nose will flow to remove excess.

2. Red face flushed

Not only a runny nose, our nose will also turn red. Along with that, the cheek blood flow will shift to more important parts of the heart, lungs . causing red face.

As long as the body is warmed, blood will circulate normally and dissolve the condition.

3. The person trembled, his teeth hit

When cold, receptors on the skin send signals to the brain. At this point, the brain will create a series of signals to warn the body, the muscles will relax, constantly contracting, trembling is one of those procedures.

Besides trembling limbs, jaw muscles will also move, making your teeth bump into each other.

4. Fingers are numb, change color white

The temperature dropped, the cold hit Raynaud's raging disease. Raynaud is a disease syndrome that causes blood vessels in the limbs to contract, limiting the flow to the limbs.

The typical manifestation of Raynaud 's syndrome is that first, the skin becomes pale (white) due to shrinking blood vessels; later turns purple due to oxygen reduction, lack of oxygen. The final stage of the blood vessels relaxes and the skin becomes reddened again.

However, Raynaud can cause you pain, numbness, needle and finger tips. The only way to deal with this cold weather is probably to wear socks and gloves.

Raynaud can cause you pain, numbness, needle and finger tips.

5. Bladder stretching, peeing constantly

When the body is cold, blood vessels will shrink, causing blood pressure to rise. To regulate blood pressure, the kidneys filter out some of the excess fluid from your blood, to reduce its volume.

When the bladder is filled with excess fluid, you will feel sad urinating. Excessive bladder will cause your body to lose heat, so urination is a way to help you stay warm.

6. Metabolism slows down

All chemical reactions in the body require energy. And when the heat is lowered, the body has to spend more energy to keep it warm.

Therefore, it must slow down the transformation to avoid unnecessary energy consumption. Therefore, when it is too cold, you should eat heat-generating foods, hot drinks to help regulate the temperature inside your body.

7. Moody, poor judgment, easy to sleep

There is a fact that when the weather is cold, the mood is often subdued. The reason is that, the temperature decreases causing the daytime to shrink, the amount of vitamin D, Tryptophan (the substance that makes Serotonin - the antidepressant hormone), the body needs to absorb deficiency, making the mood easy to get bored.

Deficiency of Tryptophan also stimulates the production of melatonin (a sleep-promoting factor) - causing emotional disorders, increasing feelings of despair, sadness, more irritability .

At the same time, the cooler the temperature, the slower the nervous system, the motor nerves that control the activity are also "lazy", making the judgment worse .
