Although it’s widely accepted that women tend to live longer than men, a new study from the Tokyo Medical and Dental University has revealed why. Females’ immune systems age more slowly than their male counterparts’, which could, in part, explain why women’s average life expectancy in the UK is 82 years while men’s is three years shorter.
Over 350 individuals participated in the study, ranging in age from 20 to 90 years old. The healthcare research showed that white blood cells, which fight infection, decrease faster in men. Similarly, women were found to maintain a higher red blood cell count.
Researchers said: “Our findings indicate that the slower rate of decline in these immunological parameters in women than that in men is consistent with the fact that women live longer than do men.”
Additionally, females’ average life span benefits from increased levels of oestrogen, which offers some protection against cardiovascular disease.
Women’s superior immune system does not, however, prevent age-related disorders, like joint wear or macular degeneration. To combat the frustrating eye condition, consider treatment through Spire Healthcare. Additionally, a number of joint injections are available to increase comfort in day-to-day life.
