Blue Light: A Curse of a Blessing for Your Sleep?

Do you like snuggling up in your bed with your smartphone right in your hands for hours and hours together? Are you someone who needs to be working till late at night for most of the time? This could affect your sleep cycles – not because you are pushing yourself to stay awake, but because of the blue light that keeps you alert and active.

Sleep is one of those pillars that are essential for optimal health. However, the blue light emitted from digital devices like your smartphone and computer or tablet may affect your sleep and lead to many other associated problems such as insomnia. The primary source of blue light has always been sunlight, but modern-day LED-based devices can also emit this short-wavelength light.

BLUE LIGHT AND SLEEP CONNECTION

Blue light promotes alertness and regulates the body’s biological clock, i.e., its circadian rhythm to determine when to fall asleep. Too much of this artificial light activates the ipRGCs (intrinsically photosensitive retinal ganglion cells) AKA pRGC (photosensitive retinal ganglion cells) and suppresses the average melatonin production.

Applying screen filters, using night mode, wearing blue light blockers for sleep, and limiting your screen exposure before bedtime can be beneficial to a great extent. This makes sure your eyes are less exposed to the harmful effects of blue light at night while allowing you to still perform your daily nighty digital activities.

BLUE LIGHT DISRUPTS YOUR SLEEP

Blue light during the day has a positive impact on your performance, mood, and overall health. However, excessive exposure at night can influence many of your bodily functions. It may be a curse for people who already find it difficult to sleep well. Poor sleep is linked to obesity, heart issues, diabetes, anxiety, and depression.

Too much blue light exposure post-evening may trick your brain into believing that it is daytime. Using blue light reducing techniques such as a pair of superior blue blockers can help in the long run.

THE BOTTOM LINE

Regardless of whether the blue light is coming from the sun or your digital devices, it can inhibit melatonin production. This eventually affects both your quality and quantity of sleep. If you already have a history of sleep-related problems, try limiting your screen time before bed, choose excellent blue-blocking gasses, and talk to an expert if any severe difficulties persist.
