Lots of people spent a lot of time on their smart phones before going to bed. Not all of them are aware that this is bad for them. We talk about radiation and the blue light which is produced by smart phones and it has been connected to serious health problems. The blue light is a part of the full light spectrum. We are exposed to it by the sun each day. This light emitted by laptops, smartphones, tablets, and other LED screens can damage the vision as it suppresses the production of the hormone named melatonin and it throws off the body;’ natural sleep cues.
Issues connected to night time smartphone use:
- Damage of the eye – the blue light causes damage to the retina, development of cataract, as well as macular degeneration (loss of central vision or ability to see what is right in front of you). There was a case where one doctor came across a 35-year-old patient with cloudy and cataract-affected eyes similar to people who are 75 years old. The root issue is the smartphone use, according to the doctor, however, more research has to be done.
- Loss of sleep – the blue light emitted by smartphones disrupts the production of melatonin (a hormone which regulates the sleep cycle of the body). If the sleep cycles are not regulated properly, then the person will not be able to get enough sleep, and lack of sleep or skewed sleeping cycles are associated with lots of health problems like: aged skin, depression, lack of memory recall, slower response time, cardiovascular issues, heart disease, and weight gain.
- Higher risk of cancer – the greater use of smartphones at night causes sleep issues, and this has been connected to higher rates of cancer,especially prostate and breast cancer. The blue light suppresses melatonin. It is an antioxidant which is essential for the natural fight against cancer of the body. Melatonin actually helps the body fight cancer, however, the blue light decreases its production. If it is disrupted one time, then it won’t be an issue, but using the smartphone hours before going to sleep can cause issues.
