The harm of 5 sedentary, you may not know the truth

Popular science like "sedentary harm", I believe many people have seen it in "love each other love each other".

The migrant workers can probably say the harm of one or two sedentary, such as backache and back pain and cervical stiffness. Everyone knows the benefits of exercise.

You must be thinking about whether I want to talk about these harms again today ...

Nonono!

Let's talk about others today -the dangers you may not know yet!

Q: Does sedentary really increase the risk of cancer?

Brother Code: Really!

This is because the sedentary slower and the blood circulation speed slows down, which will change the circulation level of insulin and sex hormones, and increase the incidence of hormone -related cancer.

Sitting for a long time will also slow down the intestinal peristalsis, the time when the food residues and toxic and harmful substances stay in the intestine, repeatedly stimulate the intestinal mucosa, causing large intestine tumors.

In addition, sedentary can easily lead to obesity, which is also a risk factor for increased tumor incidence.

Q: I heard that it is easy to get fat for a long time. It should be okay to eat less?

Brother Code: Not necessarily!

Sitting for a long time to reduce energy consumption is known, but in fact, there is still a reason for sedentary to get fat for a long time. Seating for a long time will "paralyze" the "gravity balancer" of the brain [2], making the brain unable to control the weight within a certain range. This is a "double blow" for fatty constitution!

It seems that if the house is sitting for a long time, maybe it will become fat at twice the speed!

Brother Dian just wants to say, don't try to do everything for laziness, it is better to exercise less!

Q: Sitting causes cervical spondylosis. Can a massage instrument be cured?

Brother Code: No!

If we want to answer this question, we must first understand how to cause cervical spondylosis.

When we sit in front of the desk for a long time or use our mobile phones, the shoulder and neck muscles will always be in a tight state, because the human head is very heavy.

You should know that when the head is upright, the shoulder and neck need to support the weight of about 5kg. When you use your head to use your computer or mobile phone, the head is tilted at 45 ° angle, this pressure will increase to about 22kg [3]!

So what if we sit for 9 hours a day?

Equivalent to the muscles of our cervical spine, shoulders and necks, are holding a 24 -inch luggage full of luggage every day for 9 hours!

Speaking of this, everyone should be able to understand why the massage instrument has been very effective. For the shoulder -necked muscles that have been compressed for a long time, the short massage is just a lot of money!

In addition, our cervical spine is naturally arc, and the normal physiological curvature is forward, which is the following:

(Normal physiological curvature of the cervical spine)

But when we sit for a long time, it will become like this:

(Straighten cervical physiological curvature)

This will cause neuronal nerve blood vessels to cause compression and cause common cervical spondylosis symptoms such as dizziness and numbness. The simple cervical vertebral massage instrument cannot solve the problem of changes in the physiological curvature of the cervical spine. It can only be used for assisting treatment!

Q: Sitting can cause hypertension and hyperglycemia. Is it true?

Brother Code: Really!

This is because when you can't move, the blood flow rate in your body will slow down, and the activity of various enzymes in charge of your body's sugar, protein and fat metabolism will also decrease.

In other words, the cells started to be "lazy"!

Once the cells start to "rest", the decomposition speed of fat and sugar will be reduced, the health of blood vessels will also be affected, fat and sugar will be easier to stay in the body. Three highs "!

Q: Is it just a long -seated office when working in the office?

Netizens "Sad Little Zhao": I sit at work every day for three or four hours. Should I sit for a long time? I heard that sedentary can cause strain from shoulders and necks and waist back. My body is not good.

Brother Code: Sitting for 4 hours is not a long -term sitting. The work indicates that this pot cannot be carried by me!

So what is sedentary?

First of all, let's take a look at the definition of sedentary for a long time: within one day, under sober conditions, low metabolic activities with a basic metabolic rate of less than 1.5 times, usually more than 9 hours or more are sedentary [1].

According to this description, we can know that sedentary not only includes sitting in the office, but also to go home paralyzed, lying on the weekend, lying on the weekend, taking a car and taking the subway and other low consumption activities.

If you often have back pain and back pain, then "sitting at work" may only use a part of the pot, and the remaining pots can be thrown to entertainment activities such as watching drama, playing games, and short videos.

Q: Let the body rest fully, why does it increase the risk of death [2]?

Netizens "confused Xiao Zhang": I just want to lie down and rest. Why is there any mistake? Why will rest still increase the risk of death? Turtles are often paralyzed, but aren't it longevity? (Turtles: Don't Cue)

Brother Code: There is a saying that life lies in exercise!

Through a large number of crowd investigations, it is found that in addition to the fixed posture, sedentary can also increase the incidence of many diseases, including cardiovascular diseases, cancer, metabolic diseases (hypertension, diabetes, hyperlipidemia Here), muscle disease (joint pain, osteoporosis, etc.) and depression and cognitive disorders [2].

Q: I'm so tired and don't want to move. Do you have to go to the gym or playground?

Netizens "just want to stay at home": Can you save me only if you exercise and fitness?

Brother Code: No!

Exercise more than 150 minutes per week, you can offset the adverse reactions of sedentary for a long time [4].You can also go shopping, mopping the floor, cooking, garbage, walking, standing on your computer, and even standing and calling.

The frequency of mild movement is recommended every 30 minutes. If you can't remember it, you must get up for every 4 hours after sitting.Choose the easiest way to move. Even mild activities, long -term persistence will have a lot of benefits.
