In today's technological age, the name "mobile phone" is familiar to many. A mobile phone is an electronic communication device that has the same basic functionality as a traditional landline phone, but can be carried anywhere and does not require a wired connection to the telephone network.
According to a recent study, the number of mobile phone users in the world is now more than half of the planet's population. According to a Stock Apps report, the number of mobile phone users worldwide will reach 5.3 billion in July 2021. That number equates to 67%, more than half of the planet's total population of about 7.9 billion.
According to some sources, the use of mobile phones in dark places should be banned. There are some dangers that can await those who are accustomed to looking at their cell phone screens in the dark.
Eye Retinal Damage        Â
Mobile phone screens can emit blue light, which is classified as High Energy Visible Light (HEV), which is a relatively short wavelength of visible light. Direct exposure to blue light can penetrate the outside of your eyes. For example, the habit of staring at cell phone screens in the dark has long-term negative effects on the health of the retina of the eye.
Cancer Risk
Looking at cell phone screens in the dark can also increase the risk of cancer. A study in the European Journal of Cancer Prevention found that exposure to blue light increased his risk of breast cancer by 17%. This is because blue light suppresses the production of melatonin, the hormone that puts cancer cells to sleep, and increases the production of estrogen, the hormone that causes breast cancer.
Sleep Disorders
Staring at your cell phone screen while you are sleepy can make you feel sleepy. This is due to exposure to blue light from mobile phones, which can reduce levels of the hormone melatonin, which in fact makes people sleepy. Using your phone in a dark room can disrupt your sleep and keep you from getting a good night's sleep.
Decreased Brain Power
Constant exposure of the human body to mobile phone screens can lead to sleep deprivation. This condition causes a variety of health problems, one of which is memory loss. When the body doesn't get enough sleep, the connections between neurons in the hippocampus (the part of the cerebral system that controls various bodily functions) weaken, leading to poor memory.
Increases risk of depression
Using a mobile phone in a dark room increases the risk of depression. This happens because the hormone melatonin is disrupted and sleep time is disturbed. This can affect parts of the brain that regulate emotions and anxiety.
Here are the best things you can do to avoid the dangerous habit of opening your phone screen before bed. Get into the habit of not using your cell phone between 8 pm and 9 pm. Maintain sleep quality and sleep rhythm. Reduce phone usage for non-essential tasks. To optimize precautions, you can turn off your mobile phone at least 2 hours before your break begins, day or night.
Use phone applications wisely so you don't have to rely on your phone. Keep your phone far enough away from your bedroom to ensure a safe distance for your body and brain health.
