A digital curfew means stopping screen use at least one hour before bedtime to protect melatonin production. This simple habit improves sleep onset, enhances deep sleep stages, and reduces daytime fatigue, supporting both cognitive focus and overall health.
A digital curfew involves intentionally turning off or avoiding screens—phones, tablets, computers, and TVs—for a set period before sleep. Typically, this starts at least one hour before your intended bedtime. The goal is to reduce exposure to artificial blue light that inhibits melatonin production, a hormone that signals your body to prepare for sleep.
Blue light, especially from LED screens, suppresses melatonin secretion by fooling your brain into thinking it’s daytime. Melatonin is essential for initiating sleep and regulating the circadian rhythm, your internal biological clock. Research shows that even low levels of screen luminance can delay sleep onset, reduce deep sleep, and cause fatigue the next day. One study published by the National Institutes of Health confirmed that evening exposure to blue light significantly lowered melatonin levels compared to dim light conditions, delaying sleep and reducing its quality.
Combining a digital curfew with other sleep hygiene strategies amplifies the restorative effects. This includes maintaining a regular sleep schedule, optimizing bedroom dark-out and temperature, managing stress via meditation or breathing exercises, and avoiding caffeine or heavy meals late in the day.

Yes. Setting firm boundaries reduces temptation, especially when combined with environmental changes like out-of-sight device placement.
They can help, but they don’t fully replace the benefits of stopping screen exposure altogether, which also limits cognitive stimulation.
When unavoidable, you can use screen filters and blue light blockers but aim to start your digital curfew as early as possible afterward.
Replacing screens with analogue activities like reading or light stretching creates calming alternatives without social disconnection.
