The Yantra Mat: Go ahead and scoff at this Swedish “accupressure mat” which is comprosed of 8,800 tiny plastic spikes. I did. There’s little, if any, evidence that lying on the sharp points will alleviate back pain or headaches as its marketers claim. And it definitely hurts when you first lie on it – or accidentally walk on it in the middle of the night on your way to the bathroom. But after a few minutes, laying on the mat starts to feel good, relaxing even, once you get used to the weird “tingling” sensation. The company recommends starting with 10 minutes a day and moving up to 20 to 40 minutes once you’ve acclimated. The down side is that, at $49, it’s pricey. But if it can save you a massage or acupressure treatement, as the company claims, it might be worth it.
