We’re all attached to our phones at the hip. From the moment you wake up until you go to sleep, your thumbs keep scrolling and your eyes stay glued to the screen. After all, the time before you go to sleep is the best time to scroll through your social media feed or get a head start on checking your work email.
However, health experts and studies reveal that what seems like a perfectly innocent habit may be doing your health serious harm. You may think that checking your messages and browsing your Instagram account for memes will help you fall asleep faster, but it only negatively affects your vision and overall eye health if you use your phone at night when you’re lying in bed at night.
The blue light emitted by the mobile phone at night is very bright. It affects not only your vision, but also the production of melatonin hormone, which is responsible for sleep. Consider these reasons why you should leave your phone in the other room before climbing into bed with it tonight.
1. Eye Damage
“Blue light” exposure at night has been linked to retinal damage and macular degeneration. A macular degeneration is the loss of the ability to see what is right in front of you.
Blue light exposure may also contribute to cataract development. Doctors have found 35-year-olds with cloudy, cataract-affected eyes similar to those of 75-year-olds. In his opinion, smartphone use is the root of the problem, but more research is needed.
2. Affects Sleep Duration
Mobile phone blue light affects the production of melatonin. Melatonin is a hormone that helps people sleep and regulates sleep cycles. The use of mobile phones before sleep may result in sleep deprivation as your mind may be overly excited or activated. Apart from that, the compulsive need to check your phone and scroll and refresh can delay bedtime and reduce sleep time.
3. Higher Risk of C-a-n-c-e-r
Increased light at night and resulting sleep problems have been linked to a higher rate of c-a-n-c-e-r. This is especially true for breast and prostate c-a-n-c-e-r. Melatonin, suppressed by “blue light,” is also an antioxidant and has been shown to be essential in the body’s natural fight against c-a-n-c-e-r.
Melatonin helps the body fight cancer while blue light decreases its production. There are some people who use their phones for hours before going to bed, so a one-time disruption would not be a serious problem. This happens every day. This adds up and causes the problems listed above.
4. Damages The Retina
The blue light emitted by mobile phones, specifically smartphones, has the shortest wavelength and flickers the most. It affects the vision and over time, it can damage the retina. According to the American Macular Degeneration Association, the blue light emitted from phones damages the retina, causing a temporary or reversible loss of vision.
5. Increased Risk Of Depression
Staring at your phone when you should be sleeping is not only harmful to your physical health, but also to your mental health. You are also more likely to develop depression if the blue light from mobile screens disrupts your hormones and sleep patterns. In addition, low energy levels and foggy thinking due to sleep deprivation can contribute to a sense of emotional and mental weakness.
6. Impacts Your Memory
The use of ‘smart’ phones can be harmful to your brain, contrary to their name. Night phone use and disrupted sleep make it impossible for your brain to repair connections that were damaged during the day – which is one of the main reasons you can’t think clearly after a night without sleep.
