Digital Wellness & Quality of Sleep

Key Points:

  • Mental Stimulation: Engaging with screens at night keeps the brain active, delaying sleep onset and contributing to insomnia.

  • Insomnia: A sleep disorder characterized by difficulty falling, staying, or getting restful sleep. Insomnia can lead to physical fatigue, impaired cognitive function, increased stress, mood swings, and a higher risk of chronic health conditions, 

  • Neurotransmitter Effects: Norepinephrine, histamine, and serotonin levels can stay elevated due to screen use, making it harder to relax and fall asleep.

  • Insomnia Triggers: Blue light suppresses melatonin production, while mental engagement from screen content increases alertness, both leading to sleep difficulties.

  1. Circadian Rhythm Impact: Excessive screen use disrupts the natural sleep-wake cycle, maintaining higher levels of wakefulness-promoting neurotransmitters.
