Sleep Environment Optimisation focuses on shaping your physical surroundings to support deep, uninterrupted rest. Light exposure, room temperature, air quality, noise levels, and even mattress and pillow choice all directly influence sleep quality. Small environmental changes can reduce wakefulness, improve sleep efficiency, and align your body with its natural circadian rhythms. This category isolates the core elements of your bedroom setup and addresses how to systematically refine them for maximum restorative effect.
