As weight gains, lung function decreases

As weight gains, lung function decreases

  Human lung function will naturally decline with age. However, non-communicable disease experts at the Institute of Global Health in Barcelona, ​​Spain recently discovered that getting fat can easily make the elderly lung function decline faster.
  The researchers recruited 3,700 young and middle-aged volunteers from Europe and Australia to conduct an average 20-year follow-up study. The results show that people who gain more weight in middle age will decrease lung function faster in old age; while those who maintain a stable and healthy weight throughout adulthood have a much slower decrease in lung function in old age. The research conclusions were published in the “Journal of Thoracic Cavity”.
  Researchers said that there are two possible reasons for the association between overweight and reduced lung function: one is that a large amount of fat in the abdomen and chest will limit the expansion of the lungs during inhalation; the other is that inflammatory chemicals produced by adipogenesis can damage lung function and Shorten the diameter of the airway. Maintaining good lung function for the elderly is the key to preventing chronic respiratory diseases. Weight loss can reverse the negative effects of overweight and obesity on lung health.
Growing a beard makes men more confident

  Confidence is the key to success, and appearance is a confident gas station. An internationally renowned online market research agency based in London, UK recently announced a survey conclusion that 3/4 of men believe that growing a beard gives them self-confidence and makes them more attractive.
  Researchers conducted a questionnaire survey of 2,000 Americans, and 75% of male respondents said they liked the look of their beards. In general, their satisfaction with the current facial beard has reached a passing score, and many people even hope to improve the texture, color, and growth rate of the hair. The “Hu types” that the respondents liked were “short and dense beard (22%)”, “light stubble (18%)”, and “wild stubble (18%) that has not been shaved for 1 to 2 days. In order to have a “perfect beard”, 40% of male respondents are willing to “live in a police station for one night” or “quit coffee for 1 year”; 20% would rather “no wife for a whole year”; 18% agreed to shave their heads.
  Compared with men’s love for beards, about half of the female respondents said that “a cleanly shaved face is more handsome.” Another 60% of women believe that many men do not take good care of their beards, and their hair is not satisfactory in terms of cleanliness, gloss and grooming.
Change fast, flu more

  Recently, a new study published in the journal “Environmental Research Letters” shows that rapid weather changes caused by climate change may increase the spread and risk of influenza in densely populated areas.
  Wu Zhaohua, associate professor of the Department of Earth, Ocean and Atmospheric Sciences, Florida State University, and an international research team analyzed a large amount of historical data to explore how significant weather changes affect the flu in densely populated areas in the central and northern parts of the earth during the autumn months epidemic. Areas of special concern include the United States, China, France, and Italy. The low temperature and dryness of winter create a favorable environment for the spread of influenza viruses. In the flu data from 2017 to 2018, researchers found that extreme fluctuations in autumn weather essentially caused the later flu outbreak.
  Wu Zhaohua said that global warming has accelerated the speed of weather changes. Historical flu data from different regions of the world show that flu spread is closely related to weather conditions. This is largely due to the failure of the human immune system when the weather changes in winter, making it more vulnerable to virus attacks. This study can provide reference for determining the threat and severity of influenza epidemics.
