Walking every day 1 hour is valid! Cataract is the "aging" of the eyes, but it is easily confused with presbyopia, so it is often delayed until the eyes can't see clearly before going to see a doctor. At this time, the lens in the eye has become "bad", just like the original clear and transparent protein was "cooked", it has become a blur, and there is no way to save it.
But just as we can reduce wrinkles through maintenance, in fact, we also have ways to "maintain" and "slow down" eye aging and make cataracts less prone to occur. Compared with eating lutein and group B, many people may not think that "exercise" is a very effective and cheap way.
Image source: paul williams, a researcher at iStock Lawrence Berkeley National Laboratory, found that after 6.2 years of follow-up, both running and walking can reduce the incidence of cataract.
The research team studied 32,665,438+00 runners and 65,438+0,496,5438+07 walkers, and tested their cataract incidence. The results showed that the number of people who used to walk slowly 1 hour decreased by 19% and the number of people who used to walk quickly decreased by 26.2%. The number of people who used to jog decreased by 34. 1%.
The walking speed is about 4 km/h, which is effective. In fact, the speed is not fast, it is a normal walking speed. Moreover, the walking speed is 6 km/h and the jogging speed is 8 km/h. The research team believes that physical activity can reduce the risk of cataract, whether walking or running, and the more intense the exercise, the more obvious the effect.
Exercise can help renew blood vessels and indirectly gain more new nutrition for eyes. Karolinska Medical College in Sweden has also done related research, and tracked 52,660 participants 12. 1 year, and the figures obtained are very close. People who walk or ride bicycles 1 hour every day have a lower risk of cataract than people who don't exercise at all. And people who do heavy work every day have a lower risk 16% than those who sit in office.
What's more, from the age of 30, after 10 years, the risk of cataract for people who hardly exercise is increased by 24% compared with those who keep exercise habits for a long time. Obviously, the difference between exercise and eyes is really great.
Running is very good exercise/Image source: freepik. The reason for this is that exercise can increase the efficiency of blood flow throughout the body, and the eyes are organs that need sufficient blood flow, because after daily use, the eyes will need sufficient blood flow to help metabolize the constantly produced waste and bring nutrients absorbed by the body to the eyes. Therefore, through exercise, blood flows faster and blood vessels are cleaner, which is also good for eyes.
Not only cataracts, macular degeneration and glaucoma have effects. In addition to cataracts, the research team also believes that exercise has an impact on glaucoma and macular degeneration. Because when the excess blood vessels grow below the center of the retina, the excess blood and liquid in the blood vessels penetrate into the eyes, which will form wet macular degeneration; If the blood vessels are updated, there will be no extra blood vessels in the eyes, which can naturally reduce the chance of macular degeneration.
In addition, glaucoma is related to intraocular pressure, which is also related to vascular pressure. Exercise can stabilize blood pressure and indirectly stabilize intraocular pressure, making glaucoma less likely to occur.
To put it simply, the research team believes that the eyes are very prone to aging, but as long as you spend 1 hour of easy exercise every day, your eyes can be updated, and the effect is better when used with health care products such as lutein.
