UK doctors believe that cooling could save lives by slowing the release of harmful chemicals from nerve cells, and many hospitals have adopted the idea.

Among the inventions, reported in New Scientist magazine, is a cap that blows cold air across the scalp.

Other innovations include a chilling nasal spray and an icy lung injection. Many intensive care units across the UK now use cooling techniques to help heart attack patients after two major research studies showed significant benefits.

This “therapeutic hypothermia” is normally induced using cooled pads, ice packs or even injecting chilled saline liquid into the blood stream.

New devices such as a helmet which blows cool air across the scalp have been invented which help in reducing brain temperature even faster.Cooling brain significantly reduce brain damage in stroke patients according to studies.
