Mahjong is an indispensable leisure "artifact" in many people's lives, some retired people, there is nothing to love to make friends play a few laps; every New Year's Festival, mahjong is also a must-have choice for entertainment activities
Some people like it too much, and they itch their hands without playing for three days; while some people think that the plaything is not good for their health.
So, is it good to play mahjong?
First, playing mahjong properly is really good
1. Increase communication and reduce depression
A university study published in the October issue of the journal Social Sciences and Medicine showed that playing mahjong may be beneficial in promoting mental health in middle-aged and elderly people.
The researchers selected 11,000 middle-aged and elderly residents over the age of 45 from the "China Health and Pension Follow-up Survey" project.
Overall, the mental health of the elderly who frequently participate in a variety of social activities is better, among them, urban residents who like to play mahjong have a significantly lower probability of depression.
Therefore, playing mahjong is both a leisure means to pass the time, or a social means, many people have made friends through playing mahjong, which enriches life well, reduces loneliness, and the risk of depression is low.
2. Delay aging and prevent Alzheimer's disease
Scientists believe that the brain is like a bank account, and in the process of aging, we empty the reserves in this bank account little by little. In other words, the more you reserve, the later the onset of dementia.
The amount of the reserve comes from ordinary brain activity.
When playing mahjong, drawing cards and cutting cards helps to keep the hand flexible; you also need to think about what to play, what to do, the brain simply can't stop - hand and brain together, is a rare exercise opportunity.
A new study published in the journal Neurology suggests that keeping the brain active through stimulating games such as playing cards and guessing can prevent the onset of Alzheimer's disease from being extended by 5 years.
In addition, a study published in the American Journal of Geriatric Psychiatry also found that moderate playing mahjong will be even better at delaying cognitive aging than tai chi!
Second, play mahjong healthily and keep these four points in mind
Playing mahjong has benefits, but some people rub up the future of hemp, it is easy to enter the "realm of self-forgetfulness", even one overnight after another.
As everyone knows, this is not only no benefit, but also very harmful to the body!
So to reap the benefits, keep these points in mind:
1. Control the time
Some experts have studied the elderly mahjong enthusiasts aged 65-70 and found that the elderly who play mahjong continuously for more than 3 hours will begin to increase whether systolic blood pressure (often said high pressure) or diastolic pressure (often said low pressure);
In addition, sitting for a long time, the venous return of both legs becomes more slow, which increases the risk of venous thrombosis in the lower extremities, and is more dangerous for people who have varicose veins and arterial embolism, and sudden death is likely to occur.
Expert reminder: continuous playing mahjong should not exceed 2 hours, every half hour it is best to stand up and move the limbs, kick legs, shake the head, twist the waist, stretch the arm.
2. Don't let your waist hang in the air
When standing upright, the lumbar spine load is about 100 kg, while when sitting with a bow waist and playing mahjong, the lumbar spine load is almost doubled from the normal upright position, reaching nearly 185 kg.
Such a large load, coupled with long-term playing mahjong, is prone to low back pain, especially for some people who have lumbar disc herniation and low back fasciitis, which will aggravate the condition.
Recommendation: The lumbar area needs to have sufficient support to relieve pressure on the lumbar spine.
People who love to play mahjong can buy a cushion, the middle is prominent, the upper and lower arc transitions, and it is better to have a certain hardness. When there are no cushions, fill the chair with your hips and rest your back against the chair.
3, put a glass of water on the table, do not hold the urine
Some fanatical hemp friends, in order to play one more round, can hold their urine and not go to the bathroom; in order to concentrate on playing mahjong, they dare not drink water!
Holding urine can easily induce various lesions of the urinary system, such as male prostate lesions, symptoms such as urgency and frequency of urination, and even affect sexual ability; it may also cause bladder lesions, such as cystitis, more serious and even cancerous; it will also cause damage to kidney function, such as renal insufficiency, kidney failure, etc.
Recommendation: When playing mahjong, put a pot of water next to the table, replenish water at any time, and do not hold back when there is urine.
4, don't care too much about winning or losing, stabilize the mentality
Case:
Ms. Chen of Jiangsu played mahjong all night during New Year's Day, because she was too excited to win the cards, she was emotionally excited, and suddenly fainted, and she couldn't wake up. The card friend hurriedly dialed 120 to the emergency department of the hospital and stayed in the ICU for a week before getting out of the danger period.
The doctor said that Ms. Chen herself has high blood pressure, and the blood vessels continue to be in a state of dilation and become hard and brittle, in this case, if the emotions are agitated, the blood pressure rises sharply, the blood vessels rupture, inducing cerebral hemorrhage.
Tip: Adjust your mindset, don't play too much, don't care too much about winning or losing, and play mahjong with the mentality of making friends.
