How To Improve Your Sleep With These Sleep Hygiene Tips | TUH #234

About this video

In this short solo episode, which expands the earlier sleep clip, Brecka argues sleep is a metabolic and brain-health foundation that cannot be replaced by supplements or exercise. Citing studies he summarises, he claims one week of short sleep produced pre-diabetic metabolic changes in healthy young men, that the brain’s waste-clearance system works during sleep, and that habitual short sleep in midlife was associated with higher later dementia risk. He describes topic-level sleep hygiene themes including morning light, a wind-down routine, bedroom environment and the sleep surface, and promotes his mattress and VIP course.

• Brecka argues the glymphatic system clears brain waste during sleep.
