Coming up with new developments every day, scientists are taking steps to improve the future of humanity by making new discoveries in many different fields. New researches are constantly being conducted on diseases that are still a big problem for all of us.
We have all cried when we felt sad, angry, scared or happy. Shedding tears is usually known to show an emotion. But scientists have discovered that tears can play an important role in our physical health, with a new study published in ACS Nano.
It has been discovered that diseases can be diagnosed with tears
Research led by Wenzhou Medical University in China has revealed that tears can be used to diagnose disease. Researchers have found that our body’s cellular signals can be transmitted through tears. More specifically, tears are similar to other bodily fluids that contain disease markers such as blood and urine. These fluids have been widely used in disease diagnosis for many years.
According to the explanations, in this method, called iTEARS, experts collected a few drops of tears from study participants. The liquid was then put into a machine that could filter the sample and read the findings. As a result of the examinations, it was observed that some eye disorders left traces in the tears. In addition, experts have even found that, thanks to deeper analysis, they can track the evolution of diabetes.
Luke Hee, one of the authors of the study, also stated in his statements on the subject that they plan to further their studies. Hee added that they hope the tears can be used for depression and other mental problems.
