Lesson Overview

10.4 – Caffeine and Blue Light Management: Caffeine and blue light can interrupt your sleep by keeping your brain active when it should be winding down. Caffeine stays in the body for hours, so stopping coffee or energy drinks later in the day helps relaxation come naturally. Screens from phones, tablets, and TVs give off blue light that lowers melatonin, a hormone that helps you sleep. Limiting screens at night or using warm screen filters reduces disruption. Bright lights in the evening confuse your internal clock, while dim lighting supports a calm transition to bedtime. Building awareness of these triggers gives you more control over your nightly rest. When your brain receives the right signals, falling asleep becomes easier and more satisfying. Protecting your sleep environment from stimulating influences leads to more consistent and restorative rest.
