Hello, everyone.

This is Enta.

 

Why is it important to take proper precautions against the cold?

Have you ever thought about that?

It's cold!That's right, lol.

It's because it's cold, but actually, that's not the only reason.

It's super important not to let your body get cold, even while you're working!

 

"Fatigue Caused by Temperature Fluctuations"or "Winter Fatigue"There's a saying that goes..."

After looking into it more closely, I realized the benefits of taking measures to stay warm.

Situation	Causes of Fatigue	Level of Fatigue
1. Work while properly dressed for the cold and in a warm environment	MildThermoregulation. Since warmth is primarily retained from the outside through clothing, the body's energy expenditure is minimized.	Low(Similar to normal work-related fatigue)
2. Working in conditions where you constantly feel cold despite wearing adequate cold-weather gear	ActiveAbnormal body temperature regulation (excessive activity of the sympathetic nervous system). ・Heat retention due to vasoconstriction ・Heat production in muscles (such as shivering) A large amount of the body's life energy is consumed.	High(Similar to “fatigue caused by temperature fluctuations” or “winter slump”)

🌡️ The Mechanism of Fatigue

The main causes of fatigue due to the cold are,Excessive activity of the autonomic nervous systemとApparently, it's energy consumption!

1. Strain on the Autonomic Nervous System

Maintain a constant body temperature (approximately36°) is responsible for maintainingAutonomic Nervous System。

• In situations where you feel cold (Situation 2), the body activates the sympathetic nervous system to prevent heat lossIt stimulates active functioning.

  • It constricts the blood vessels in the skin and reduces blood flow.

  • Generates heat within the body (by causing muscles to tremble or boosting metabolism).

• ThisA prolonged state in which the sympathetic nervous system is dominant and overactiveAs a result, the balance of the autonomic nervous system is disrupted, and the nerves themselves become exhausted. (You just keep getting more and more tired.) The moment you get in the car on the way home, you start to feel warm, the fatigue sets in, and you get sleepy, don't you?

2. Energy Waste

Excessive activity of the sympathetic nervous system raises body temperature in order toA lot of energyConsume!

• Basal metabolic rate increases, and energy sources (primarily carbohydrates and fats) are burned more quickly than usual.

• This excessive energy consumption, combined with work-related fatigue,General fatigueやLethargyappears as. This is “Fatigue Caused by Temperature Fluctuations" or "Winter Fatigue"These are typical symptoms of a condition known as ."

3. Poor Circulation and Muscle Stiffness

When blood vessels constrict due to the cold (Situation 2), blood flow is impaired.

• Poor blood circulation makes it difficult for fatigue-inducing substances and waste products to be expelled from the body, causing them to accumulate in the muscles.

• As a result,Stiff shoulders, headaches, lower back painThis causes symptoms such as [...], which in turn further increase feelings of fatigue.

It's kind of scary when you read it like this, isn't it~~!

Winter Clothing

Apparently, the way to prevent that is to "Keep the Three Necks Warm!?"

Body Part	Benefits of Warming	Effects on Fatigue Reduction
Neck (Cervical Region)	Preventing misperceptions in the brain and stabilizing the autonomic nervous system. The neck contains an important sensor that detects body temperature; warming this area causes the brain to determine that “the body is warm,” which helps suppress excessive sympathetic nervous system activity.	Preventing Autonomic Nervous System Exhaustion
Wrists and Ankles	Improved Peripheral Blood Circulation. By directly warming the large blood vessels, this prevents the blood circulating throughout the body from cooling down and stops cold blood from returning.	Maintains blood flow and helps eliminate waste products
General	Efficient Heat Retention. Since these areas have little fat and thin muscle layers, cold air can easily penetrate them and heat escapes easily (they dissipate heat easily). Covering these areas can significantly reduce the amount of heat lost from the entire body.	Reduce the body's consumption of vital energy

 

What are you all wearing to stay warm!?

What do you think?

If these three key areas haven't been addressed, please take the time to thoroughly review them.

And if you focus on keeping this area warm, you might find that your fatigue disappears in an instant!

Make sure to bundle up to avoid getting tired!

 

See you later.
