New study reveals that activities reduce the risk of developing one of the diseases that most cause vision loss in Brazil
Scientists at the University of California, USA, evaluated more than 11,000 people in their 40s and found that among the most physically active , the incidence of glaucoma was significantly lower. Yes, exercise works well for the eyes.
To get an idea, every ten minutes or more of moderate to intense practices per week, the danger of suffering from this problem was down 25%. The finding is interesting mainly because, until recently, it was not believed that lifestyle had any positive influence against the advancement of this condition.
More: glaucoma affects up to 1 million Brazilians, has no cure and is one of the leading causes of blindness in the world. And detecting it early is a challenge, since it does not manifest many symptoms.
“The disease will gradually impair peripheral vision until it reaches the center . But this gradual loss is difficult to notice before reaching an advanced stage, “says Lisia Aoki, an ophthalmologist at the Hospital das Clínicas in São Paulo .
It’s working out to see
The link between exercise and good vision is new and still lacks further study. But some mechanisms behind it are already suspected.
“We know that one of the important factors to develop glaucoma is the blood flow that the optic nerve receives,” explains Lisia. “From there, we conclude that pictures that alter circulation in this region, such as high blood pressure or diabetes , may increase the risk of the disease appearing,” concludes the doctor.
The constant strides, in turn, combat chronic evils like these. That is, it would remove the problems behind glaucoma.
To defeat glaucoma
In addition to keeping an eye on physical fitness, it is best to take preventive exams regularly from age 40 onwards. “Those who have cases in the family should be more attentive,” says Lisia. The tests measure intraocular pressure – it is when it is elevated that there is an increased risk of injury to the optic nerve – and assess the state of the nerve itself.
In recent years, other conditions have been associated with the disease, such as sleep apnea, nocturnal arterial hypertension and the indiscriminate use of eye drops.
