"When I was in college, I stayed up all night studying until I took the final exam the next afternoon, and then went to sing at night. It was no problem!" "Ah, what about now?" "Now ... I 'm sleepy as hell at 10pm after coaxing the kids . , Sigh ... " Talking about bravery is not just for men. Everyone always brags about how they were when they were young. But as we grow older, our bodies will also age. What is the so-called "aging"? What is it? What happens to the so-called aging? What can we rely on to slow down aging?
Reduced metabolic rate
As we age, our metabolic rate decreases year by year, which means that the body does not metabolize fat as quickly as before . When I was young, I ate chicken steaks casually as a late-night snack, and I didn't necessarily gain any fat. Now that I am older, if I eat two more bites of hot pot on weekends, my pants will sound a warning that they are getting tighter. When I was young, if I skipped two meals, my stomach would shrink significantly. Now that I'm older, I worry about edema the next day even if I drink too much water.
weakened immune system
Also because the above-mentioned body metabolism speed is reduced, which means that the speed of eliminating bad cells and germs is also slowed down. When foreign viruses invade the human body, the elderly's body must take longer and require more physical strength to recover . This is why influenza and COVID-19 pose such a great threat to the elderly. In the past, it may not be a problem to exercise as usual if you have a minor cold. If you are over 30 years old (although not yet qualified as an "elderly"), it is better to wait until you have fully recovered from the cold before resuming exercise. After all, the body's physical energy is limited. If most of the energy is used for exercise, there will be no extra energy to fight the virus .
Decreased bone density
As age increases, minerals in the bones will be lost in large quantities, forming what is called "osteoporosis". This is not unfamiliar to elderly people. Osteoporosis not only increases the risk of fractures, but also means that the supporting strength of the bones becomes worse. In more serious cases, it means that you cannot stand and walk normally . Smoking, alcohol abuse, and lack of physical activity can aggravate the symptoms of osteoporosis. If you had these bad habits when you were young, be sure to get rid of them as soon as possible.
Ways to delay aging
Engaging in sports is definitely the method with the highest CP value, especially weight training. Weight training not only increases muscle mass and increases basal metabolic rate, but also effectively increases bone density. It is like touching clams and washing pants at the same time . There are many rumors that weight training will wear out joints, but there is actually no scientific basis for it. As long as there is a professional coach to guide you and the posture is correct, weight training is definitely much more friendly to the joints than mountain climbing and other ball sports , so don’t believe anonymous reports or farms in the group. Article. Starting today, start weight training. Not only can you look younger, but you can also live healthier!
