Sleep is one of the most vital components of your health. Simply limiting stimulation before bedtime can drastically improve the quality of your sleep. It prepares your body for sleeping and activates the release of melatonin resulting in overall regulation of your circadian rhythm.
Artificial lighting and electronic gadgets emit blue wavelengths which could trick your brain that it’s daytime already. This could disrupt your natural sleep-wake cycle leading to a series of problems associated with sleep deprivation.
Bright lights and loud noises can increase stress hormones in your body, requiring your body to produce tons of inhibitory neurotransmitters just for you to feel sleepy.
Blue light emissions disrupt the production of melatonin, making it difficult for you to achieve meaningful sleep.
There is no adverse effect in toning down your activities before bedtime.
