    Obesity (generally defined as body mass index BMI>30) has been considered a chronic disease.

    According to the World Health Organization (WHO) report, obesity has become a worsening global health crisis.
    More than 1 billion adults are overweight and at least 300 million are diagnosed as obese.

    Overweight or obesity is still the main factor leading to the incidence of chronic diseases and disability, while also putting great pressure on the immune system.

    Therefore, finding easy-to-implement and cost-effective methods to solve the obesity problem is particularly important for health.

    Recently, a study published in the journal Neurobiology of Aging showed that being overweight or obese can greatly reduce blood flow in the brain, but increasing physical exercise can positively change or even offset this decrease in cerebral blood flow.

    In this study, the researchers surveyed 495 participants over the age of 50 from the Irish Longitudinal Aging Study, and explored through different obesity measurement indicators, including body mass index, waist-to-hip ratio, waist circumference, and physical exercise.
    Its relationship with cerebral blood flow.

    The results showed that the measurement of cerebral blood flow through MRI scanning and analysis technology found that the increase in body mass index, waist-to-hip ratio and waist circumference was related to the decrease in cerebral blood flow, and an increase of 1cm in waist size was the same as the decrease in cerebral blood flow every 1 year.
    .

    However, physical exercise may change the association between obesity and decreased cerebral blood flow.

    When dealing with the decrease in cerebral blood flow, the study recommends that at least 1.
    5 to 2 hours of moderate and light physical exercise, including brisk walking or cycling, should be done every day.

    In addition, the researchers emphasized that any increase in physical activity, especially activities that have been integrated into daily life, such as gardening, can help maintain and possibly improve cerebral blood flow.

    At the same time, the researchers said that it is important to continue to supply blood to the brain healthy, because it can ensure that the brain has enough oxygen and nutrients.

    If the blood flow to the brain is impaired, it can cause serious health problems with age, such as increasing the risk of dementia and Alzheimer's disease.

    As we all know, obesity makes it easy for people to suffer from age-related diseases.
    Even after the age of 40, life expectancy is reduced by as much as 6 years, and women's life expectancy is reduced by as much as 7 years.

    In summary, the study reveals the link between obesity and reduced blood supply, but physical exercise is very important for people who are overweight or obese, which helps prevent reduced cerebral blood flow and the resulting health problems.
