Accupressure works! It acts as an irritant/stimulant, making the body pump hot blood, along with adrenaline, to the affected area. As a result, muscles are warmed up, lactic acid gets dispersed a bit, and adrenaline acts as a painkiller.
Yoga mats: A little advice:
Thicknesses range from 1/8 to 1/4 inches. Most yoga mats have thicknesses around 1/5 inch -- which is recommended if practicing on a hard surface -- but premium mats closer to 1/4 inch and super-thin yoga mats and towels around 1/20 inch thick are also offered. Some practitioners prefer thinner mats, which allow them to feel more stable on the ground.
Yoga style matters. For instance, people who practice vigorous Ashtanga or Bikram yoga -- more intensive styles that generate a good amount of sweat -- should look for mats with a solid nonslip surface or invest in a yoga towel. Some heavy sweaters prefer open-celled yoga mats, which absorb sweat and prevent slips, but they can be less hygienic and harder to clean than closed-cell mats.
