Let’s face it, we all like to browse the Net, play a game, or use some new application on the smartphone before going to bed. You might want to check the weather forecast for the next day, chat with your friends, or see the pictures you took that afternoon.
Yet, researchers are constantly examining the effects of smartphones on our health and wellbeing and their findings are not positive.
You might have already heard of cell phone radiation, which is a thing numerous people worry about. Apparently, the blue light emitted by these phones causes various severe health problems.
Scientists have confirmed the relation between smartphones and the following health problems/diseases:
The blue light affects your good night’s sleep, and increases your risk of developing cancer, especially breast and prostate cancer.
Melatonin is your body’s natural weapon against cancer. The blue light suppresses it, and excessive exposure to it can create a perfect soil for the development of severe health problems.
People whose melatonin levels are suppressed, and whose body clocks are modified by light exposure are also more prone to depression. Lack of sleep interferes with our neurotransmitters, and can ultimately lead to a decline in synaptic signalling between neurons, which normally regulate our mood.
Disrupts the brain
Not getting enough sleep caused by smartphone light can also make it harder to learn, and may leave you distracted and impair your memory the next day. When comparing the brain of sleep deprived individuals with those who have received plenty of sleep, scientists have found reduced metabolism and blood flow in multiple brain regions. This results in impaired cognitive function and behaviour.
It can damage your eyes
There is some evidence that blue light can damage our vision by harming the retina over time and causing macular degeneration (the loss of central vision, or the inability to see what is right in front of you).
Artificial blue light is one of the shortest, highest energy wavelengths in the visible light spectrum. Because they are shorter, the wavelengths flicker more easily, which creates a glare that can reduce visual contrast and affect sharpness and clarity. This is often the case for why people experience digital eyestrain and suffer from symptoms like blurry vision, difficulty focusing, dry and irritated eyes, headaches, neck and back pain, after a days work at the computer.
Since quitting using my phone at night, my mystery morning eye strain that would often last into the afternoon went away. It felt like I hadn’t slept at all, but really, it was just the effects that the blue light had on my eyes.
The blue light disrupts the production of melatonin and this hormone can trigger insomnia and irregular sleeping patterns. Over time, lack of sleep may also cause various of other ailments, such as weight gain, memory loss, aging skin, depression, and cardiovascular issues. So, if you cannot fall asleep without your phone, try reading a book as an alternative.
As mentioned before, the blue light affects melatonin levels. You need this hormone to enjoy a normal sleeping cycle. The lack of melatonin causes irregular sleeping pattern, and causes the following issues:
- Cardiovascular problems
- Memory issues
- Premature aging
- Slow responding
- Vision problems
