New studies have found benefits from getting regular, good sleep including increased happiness, calmness, energy, and mental sharpness. A study of 204 college students found improved well-being, health, and composure when transitioning to regular sleep schedules. Additionally, professional baseball players who increased their sleep by one hour for five nights demonstrated faster mental processing and less tension and fatigue. Nutritional supplements like magnesium and calcium have also been shown to increase sleep quality and duration by reducing stress hormones and providing deeper, less interrupted sleep.
