This mat stimulates pressure points to relieve tension and stress. Acupressure mats are equipped with small spikes that apply pressure to the body, promoting relaxation and reducing muscle tension. Regular use can help alleviate anxiety symptoms. While they look like modern day torture, and take some time to get used to, I can’t recommend these mats enough! Getting on an off them at first is a challenge. Now that I am used to it, I often fall asleep so have learnt to set an alarm before I lay down! I don't tend to use the pillow but I think this comes down to personal preference. Within the first 3 minutes of laying down your back will get a warming sensation as the spikes encourage circulation and blood to flow to the surface. This is a very relaxing feeling and has a similar effect to dry needling to your muscles. This is the one I have.
