From a Wall Street Journal story by Jen Murphy headlined “Elite Athletes Swear by These Extreme Treatments. Scientists Think They Could Boost Your Health, Too.”:

Infrared light waves. Electromagnetic fields. Extreme cold therapy. Treatments popular among elite athletes are now influencing the science of extending life and health.

In June, Mass General Brigham healthcare system opened a 20,000-square-foot laboratory and training facility in Foxborough, Mass., devoted to sports-performance research. It includes a cryostimulation chamber with temperatures as low as -220 degrees Fahrenheit and a device known as a photobiomodulation bed for light therapy.
