Why your brain shrinks every single night

The episode examines the biological and environmental factors that influence sleep quality, mental health, and stress management. Scientific research highlights that restorative sleep is vital for brain detoxification and physical repair, while chronic deficiency elevates the risk of cardiovascular disease and dementia. Experts recommend lifestyle interventions such as consistent sleep schedules, regular exercise, and maintaining a cool, dark environment to optimise rest. Therapeutic approaches, including meditation and magnesium supplementation, are shown to reduce cortisol levels and improve mood by balancing the nervous system. Additionally, clinical evidence suggests that technological solutions, such as temperature-controlled bedding, can enhance sleep architecture and cardiovascular recovery.
