Science explores the link between daily habits, nutrition, and brain health

Recent scientific research highlights the interconnectedness of daily habits and brain health. Neuroscientist Jesús C. Guillén explores how light exposure, movement, nutrition, and social connections influence cognitive and emotional well-being throughout a 24-hour cycle.

Specific focus is placed on the bidirectional relationship between nutrition and sleep. Research led by Marie-Pierre St-Onge at Columbia University indicates that dietary patterns significantly impact sleep quality. High fiber intake is associated with increased deep sleep, whereas diets high in saturated fats and sugar are linked to lighter, more interrupted rest. Experts suggest that rather than seeking a single “superfood,” maintaining a consistent pattern of whole foods, vegetables, and grains is essential for optimal sleep and neurological function.
