In an initial trial, the warm home prescription pilot paid to heat the homes of 28 low-income patients. Those running the trials had achieved such good results, they planned to expand it to 1,150 homes. So why is heating a wonder drug and do the figures stack up? Cambridge University physiologist Christoph Schweining knows all about how we keep warm and stay cool. He often puts his knowledge into practice as a highly successful marathon runner.
