🧠 What Is Blue Light?

Blue light is a type of light with a short wavelength and high energy. It is naturally present in daylight and plays an important role in:

• Boosting alertness
• Improving reaction time
• Regulating the body’s internal clock

Festival of Sleep Day highlights that while blue light is helpful during the day, it becomes disruptive at night.

🌙 How Blue Light Affects Sleep

Blue light has a strong effect on the body’s sleep-wake cycle.

In the evening, blue light:

• Suppresses melatonin production
• Delays feelings of sleepiness
• Keeps the brain in an alert state

Festival of Sleep Day emphasises that exposure to blue light after sunset can make falling asleep significantly harder.

📱 Common Sources of Blue Light at Night
