Mobile phones have become a constant companion in our daily lives. Screen time has become inevitable since it is possible to check messages or scroll social media or even watch videos. Although the use of screens throughout the day is not as dangerous in a healthy balance, mobile phone use at night is extremely dangerous to the quality of sleep as well as the well-being of the eyes. This difference can be used to make better screening strategies.
When you use the screens during the day, it is generally less harmful since our body is already awake and in touch with the outside world. The light during the day is also useful in controlling the internal body clock, also referred to as the circadian rhythm. Your eyes have more capabilities to deal with screen brightness when you play on your phone or laptop in the daytime and the set of blinking is more natural.
However, the eye strain, headaches, and dryness may still be observed even because of the long hours of constant screen time.Most scree daytime screen-related problems can be mitigated by taking frequent breaks, enjoying sufficient lighting and conscious blinking.
The effect of using screen at night is much more harmful as it disrupts the process of preparing the body to sleep.Mobile screens have a blue light, which inhibits melatonin- the hormone that makes you want to sleep.In case of a fall in melatonin concentrations, your brain is awake when you are worn out.
Consequently, you might have difficulties falling asleep, frequent awakenings or sleep incompleteness. This is a bad sleeping pattern, which, however, in the long run will result in tiredness, mood swings, lack of concentration and a weaker immune system.
Playing with the phone in the dark places undue strain on your eyes.The difference between a bright screen and a dark room makes the eye muscles to strain more, thus resulting into the development of dryness, irritation, and blurred vision.The burning or watering in the eyes of many people also occurs as a result of night scrolling.
Less blinking while looking at screens aggravates dryness. Having long-term exposure can also provide to the digital eye strain, as well as leads to the higher likelihood of longer-term vision discomfort.
Inadequacy of sleep does not simply turn you into a sleepless machine. It influences the hormone balance, metabolism, psychological health and heart health. Sleep deprivation has been associated with an increase in weight and anxiety as well as memory and productivity impairment. Mobile phone usage at night silently fuels this cycle, leading to worsening sleep problems over time.
It is better to avoid using mobile at least an hour before one sleeps in order to minimize the harm.When you have to use your phone, make screen brightness lower and turn on night mode or blue filters.Turn on the room lights instead of turning on your phone when it is completely dark.When it is daytime, apply the 20- 20-20 rule; after every 20 minutes, look at something 20 feet away at least 20 seconds.The last and most important, replace night scrolling with relaxing activities such as reading a book, stretching, or meditation.
It is the timing that is important but not screen time itself. Using the screen in the day is more comfortable for the eyes and sleep cycle, whereas using the mobile at night interferes with sleep hormones and puts a strain on the vision condition. Minor lifestyle modifications can help you save your eyesight, sleep better, and live better lives.
