AMA #13: Winter Months & Sickness, Wim Hof Breathing & Stressors

About this video

This AMA covers winter sickness, Wim Hof breathing and stressors. On why colds and flu surge in winter, Huberman explains that the nasal passages are a front-line defence: hairs, mucus and the trillions of microbes in the nasal lining protect the nearby brain and respiratory pathways from incoming infections. He recommends keeping the air you breathe sufficiently humidified, especially at night, so that this mucosal lining stays intact and resistant, for example by using a humidifier in a bedroom where you spend many hours. Huberman notes this will not stop an actively sneezing person from transmitting an infection, but stresses that the body is constantly fighting off viral, bacterial and fungal challenges, and that poor sleep makes symptoms noticeably worse when an illness does take hold.
