Sleeping in the Dark: 10 Surprising Effects on Your Body
第1話 - 1. The Importance of Light in Our Sleep Patterns
Light plays a crucial role in our sleep patterns. Our bodies are naturally programmed to be awake when it's light and asleep when it's dark. Light exposure, especially natural sunlight during the day, helps regulate our internal body clock, known as the circadian rhythm. It tells our body when to be alert and when to wind down for sleep. Without proper exposure to light, our sleep-wake cycle can become disrupted, leading to difficulty falling asleep and waking up, as well as daytime sleepiness. So, ensuring a dark environment when we sleep helps to align our bodies with this natural rhythm and promotes healthy sleep.
