Humming, I am told, can help stimulate our vagus nerve and slow down our heart rate. And I do start to feel a bit more relaxed. I can feel the low hum vibrating in my body and my brain seems a bit less busy.

At this somatics class, yoga therapist Eirian Collinge guides us through a session of gentle moves combining deep breathing, rocking and swaying.

While she doesn't buy into all the techniques on socials, Eirian says there are parts of her practice that use breathwork, eye movements and tapping.
