Yes — even small amounts of light at night can disrupt your brain’s rest by interfering with sleep quality, circadian rhythms, and melatonin production.

🌙 Why Darkness Matters for Sleep
Melatonin regulation: Your brain’s pineal gland produces melatonin in darkness. This hormone signals your body to sleep. Even dim light can suppress melatonin, delaying sleep onset and reducing sleep depth.

Circadian rhythm disruption: Light exposure at night confuses your internal clock, making it harder to maintain a healthy sleep-wake cycle.

Brain rest: Studies show that nighttime light exposure increases risks of fatigue, confusion, and impaired daytime functioning.

Health impacts: Chronic exposure to light at night has been linked to inflammation, mood disorders, and metabolic dysfunction.

💡 Sources of Nighttime Light
Streetlights, billboards, and car headlights (light pollution)

Indoor sources like nightlights, phone screens, or TV glow

Even very dim light (like a digital clock display) can affect sensitive sleepers
