How does Wim Hof's breathing method affect the body's immune system?
Wim Hof's breathing method has been studied for its potential effects on the body's immune system. The technique appears to enhance the body's ability to respond to pathogens and potentially increase the activity of natural killer (NK) cells, which play a crucial role in the immune system by identifying and eliminating infected or cancerous cells. Additionally, the increased production of endorphins due to the breathing method may contribute to a stronger immune response, as these hormones have been found to improve overall well-being and resilience against illness.
