Relax at the touch of a button?: Why is the hype about the vagus nerve justified?

According to Gregor Hasler (55), Professor of Psychiatry and Psychotherapy at the University of Fribourg, the calming effect of neck massages and breathing exercises is indisputable. “The vagus nerve is responsible for this,” he says. This is our longest nerve in the human body. It extends from the intestines, liver, stomach and lungs to the head and brain.

Stimulate the relaxation nerve

The vagus nerve (short: vagus) is part of the parasympathetic nervous system and is responsible for stress reduction and relaxation. “It allows our heart rate to slow down, our blood pressure to drop, and our breathing to calm down,” says Hasler.

The expert says that the vagus nerve can also be stimulated to increase its effect. “The nerve passes through our neck and moves towards our head. It is stimulated by neck massage.” Branches of the nerve also extend to the respiratory tract and vocal cords. Therefore, the vagus can also be activated by deep breathing or a gentle humming sound. The facial nerve can be stimulated with the help of a facial bath. Hasler: “With each stimulus, the nerve tells the brain: Everything is fine, there is no need to worry.”

Hype is based on science

The advantage of this type of vagal stimulation is clear, says Hasler. “The effect is immediately noticeable.” The body’s own messenger substances, hormones, take much longer to take effect. Hasler: “The Vagus is a kind of information highway in our body.”

According to Hasler, the relaxation tips shared on social media have a scientific basis. Vagus therapies are now popular even in clinical settings. For example, in patients with epilepsy: “Stimulation of the nerves can relieve their symptoms and weaken seizures.”

Not a panacea

Because we’re constantly exposed to stressors in our daily lives—heavy traffic, noise in an open-plan office, or notifications on our cell phones—the vagus nerve is often underactivated, says Hasler. When you are stressed, stress nerves are activated. They prepare our body for possible dangers. “Relaxation and reassurance will only be a hindrance.” But Hasler says stimulating the vagus nerve through massage or breathing exercises isn’t a guarantee of getting rid of all stress. “First of all, chronic daily stress cannot be eliminated this way.”
