Twins exhibit health benefits over singletons

Physicians stress that one must get adequate sleep, practice good eating habits and exercise regularly to ensure a healthy life. A recent study reported that being a twin further boosts life expectancy. PLOS ONE confirmed that twins, particularly male identical twins, possess a survival edgeover singletons.

David Sharrow and James Anderson compiled this comprehensive inquiry by utilizing data from the Danish Twin Registry and the Human Mortality Database. The twin files include all monozygotic, or identical, and like-sex dizygotic, or fraternal, twin pairs that were natives of Denmark between 1870 and 1900. Sharrow and Anderson examined 2,932 pairs of same-sex twins that had finished their lifespan. They then analyzed their ages at death for comparison. The authors created a “vitality model” to remember that the twins may have different demographics. Their investigation separated the causes of death into two brackets—intrinsic and extrinsic factors—where “intrinsic” alludes to old age and “extrinsic” is an environmental influence.

Twins outshined nearly every age and both sexes in external sources of death. Identical twins achieved the topmost scores. The research divulged that identical twins enjoy more longevity than fraternal twins and the Denmark population. There is no distinction in intrinsic causes between zygosity or the conventional female population. However, monozygotic females have supremacy over dizygotic females and the general population when it comes to extrinsic death. This is also relevant to monozygotic males. Monozygotic males lived to the oldest age because they have a slow progression of vitality loss, contributing to a greater amount of vigor altogether. They are less vulnerable to environmental troubles and only encounter minor difficulties in comparison to dizygotic males. Similarly, they had less adversities than the overall male population in the study.

The prosperity of monozygotic twins can be traced back to psychological reasons. For instance, psychologists in recent years discovered that married couples had lower death rates than single people. Married women and men are less susceptible to heart disease, Alzheimer’s and depression. Social scientists concluded that a wife and husband share a strong emotional connection and that marriage has rewarding aspects, such as partners being supportive of each other’s health practices. This is evidently applicable to twins. The “twin protection effect” is equivalent to a marriage protection effect—a relationship that provides superior survival effects later in life. Social intimacy of monozygotic twins contributes to behaviors that amplify immunity and life expectancy. Having a twin means having a secure bond that will usually be assured steadfastly through life. Twins share an unparalleled link and a good well-being arises from such a close association since birth.

The results of the study reveal that it is important to maintain a balance of work and leisure. Uncomplicated actions, such as venting to a friend lead to love and appreciation; a longer life is now one with a multitude of benefits.
