Why do girls have cold hands and feet? Because this place is more developed than boys

When winter comes, do you feel your hands and feet are very cold?

Especially when sleeping, I felt like I was going through a tribulation. I wrapped myself in the quilt again and again, but I couldn’t get warm all night.

But strangely, my boyfriend's bed was as warm as a stove , forming a sharp contrast...

The question is, why do girls tend to have cold hands and feet?

#01

Girls have a strong sensory system

More sensitive to temperature

To be honest, girls have a stronger sensory system than boys and are better at judging temperature.

All of this is actually caused by estrogen.

Estrogen is an amazing hormone that helps regulate body temperature.

Compared with boys, girls have higher levels of estrogen in their bodies, so they are more sensitive to changes in temperature and have a stronger ability to regulate their body temperature.

That is to say, under the same temperature change, boys may not feel anything, but girls will already feel cold.

#02

Cold hands and feet

It is actually the body’s protection mechanism for us.

What exactly is going on?

This has to start with the muscles in our body that are experts in producing heat.

Generally speaking, girls have less muscle than boys and their ability to produce heat is relatively lower.

Also, when muscles generate heat, blood vessels transport it throughout the body.

As important organs of the body (such as the heart and lungs), more blood will flow here to keep them warm first.

The extremities of the body, such as the hands and feet, naturally receive less heat.

These factors combined can make your hands and feet cold.

#03

Girls are more likely to have cold hands and feet. This is natural.

It turns out that scientists had thought about this as early as 1998.

A study in the authoritative medical journal The Lancet found that girls' hand temperature is about 1.5°C lower than boys'.

The average hand temperature for women is only 87.2 degrees Fahrenheit, while that for men is 90 degrees Fahrenheit.

That is, women are 2.8 degrees Fahrenheit lower than men , which translates to about 1.5 degrees Celsius.

Another study in 2018 also proved that the comfortable temperature for women is 24.0℃ and for men is 23.2℃.

It seems that girls' body surface temperature is naturally lower than boys', and they prefer warm environments.

Although most cold hands and feet are a normal reaction of the body, there are some special cases , such as:

Hypothyroidism: You may be afraid of cold, have cold hands and feet, and your skin may become dry and rough .

Anemia: **** Cold hands and feet may be accompanied by symptoms such as dizziness, palpitations, and pale skin .

Everyone, please pay attention. If any abnormal situation occurs, you must go to the hospital for treatment in time.

There is help for those with cold hands and feet!

Master these 3 tips to stay warm in winter

The weather is getting colder and colder, don’t you want to shiver with cold?

Here are 3 simple and practical methods. I heard that the last one can be done without spending any money or effort.

① Dress warmly

Here I recommend you to try the onion dressing method , which is really convenient and warm.

As the name suggests, this method is like an onion, wearing layers one by one, and can be put on and taken off freely according to different temperatures and environments.

Inner layer: You can choose woolen underwear, quick-drying base shirt, etc.

Middle layer: polar fleece, fleece, and down vests are all ok.

Outermost layer: Preferred jackets, windproof jackets, down jackets, etc.

② Exercise

Exercise is one of the best ways to warm up your body.

Choose a sport that interests you and stick to it to enhance your ability to keep warm.

③ Of course, there is also the most convenient way -

Find a boyfriend who can provide heating and maintain a constant temperature.

I believe I don’t need to say more about what to do next.
