Heat Therapy and Pain Relief:

Scientifically Proven Benefits
of Heat

Why does heat help?


Studies have proven that heat has a similar effect to a painkiller, effectively “deactivating” pain at a molecular level. In this way, completely naturally and without any chemicals, heat blocks pain and helps with issues such as menstrual pain, neck tension and abdominal cramps, and even diseases such as endometriosis or Crohn’s disease.
