Anti-aging and longevity are our eternal discussions, and everyone seems to have his own theory. Some people think that we should exercise more. Some people think that we should eat more antioxidant foods. Some people think we should soak our feet more. But you would never think that tickling can also delay aging.

A study by the University of Leeds in the United Kingdom believes that tickling is not only a prank on friends, but also beneficial to our health. The "tickling therapy" adopted helps to delay aging.

In order to verify this view, the researchers conducted related experiments.

In the experiment, 29 healthy volunteers over 55 years old were recruited and tried to use "tickling therapy" to treat the volunteers. The main stimulation site is the ear, including tickling and low current stimulation. Each participant received 15 minutes of treatment every day and taught himself at home.

After more than two weeks of testing, it is found that volunteers' mood and sleep quality have improved obviously after tickling for a short time every day, which is really helpful to their health.

Simply stimulating the ear can delay aging. What principle is tickling therapy based on?

The tickling treatment process, also known as percutaneous auricular vagal nerve stimulation, is helpful to balance the autonomic nervous system of human body and recalibrate the internal control system of human body. The autonomic nervous system plays an important role in the human body, mainly supporting functions independent of conscious thinking, such as breathing, blood pressure, heart rate and digestion.

This tickling therapy can effectively improve the health status of people aged 55 and over. Because the sympathetic and parasympathetic nerves in the autonomic nervous system of the elderly are usually unbalanced, the imbalance between them will increase the risk of illness.

Applying a small current to the ear nerve will stimulate the vagus nerve in the parasympathetic nervous system and make the gradually unbalanced autonomic nervous system gradually return to normal, thus reducing the risk of chronic diseases such as hypertension, heart disease and atrial fibrillation. Our ears are like a channel, which can adjust the body system without additional drugs or invasive objects.

Researchers also believe that stimulation like this will have a great impact on our lives, and this impact will also extend to other health problems. In order to know whether tickling therapy will have a long-term impact on health, the research team will continue to study it.
