Having trouble opening the jars? It could be a sign of serious illness

Failing to open a jar or hanging yourself from it several times before you do so could be a worrying sign, according to a new study. Grip strength is an indicator of disease and lifespan.

Opening the jars is sometimes an obstacle course. If our physical strength is often called into question, it could be that the reason for these failures is much more serious. According to many researchers, grip strength is an indicator of disease and longevity. Failing to open a jar of jam could therefore be a worrying sign.

To confirm this hypothesis, scientists in Austria undertook research and asked participants in their study to squeeze a device called a dynamometer twice in each hand, a standard way to measure grip strength.

“Our task was to find the threshold related to handgrip strength that would signal a practitioner to do further examinations if a patient’s handgrip strength is below this threshold. This is similar to measuring blood pressure”, explained Dr. Sergei Scherbov, the lead author of the study. Similarly, when the blood pressure level is outside a particular range, the doctor can either decide to prescribe a particular drug or refer the patient to a specialist for further examination.

No need to strengthen your hands and forearms

Specifically, they found that grip strength just slightly below the average of a comparable population was associated with a risk of heart failure, diabetes, cancer and dementia. “Monitoring the grip strength of elderly and middle-aged people can provide great benefits. Therefore, we suggest that it be used as a screening tool in medical practice”said co-researcher Nadia Steiber, from the University of Vienna.

The scientists also wanted to remind that it was useless to strengthen his hands and forearms to reduce the risk of death. A healthy lifestyle and regular exercise are the best ways to maintain or improve long-term health.
