One of the most basic biological processes of human functioning is sleep. It helps to consolidate memory, regulate emotions, improve the work of the immune system, and restore the body, in general. Regardless of its significance, many people in the digital era have lost their sleep quality. The use of technology in the pre and during bedtime period is one of the main factors that cause this downturn. The digital habits antiquely dictate the time in which people sleep, the level and quality of their rest.

Electronic devices produce blue light that disrupts the synthesis of melatonin, a hormone that helps in the sleep-wake rhythm. In cases where there is inhibition in the production of melatonin, then the body will be in an alert state. Although a human being is physically exhausted, the brain might not have an easy time shifting to a sleep state. This distortion in biology complicates the falling asleep and also decreases the overall sleep quality.

Other than the exposure to light, what one eats prior to sleep is a major factor. Social media feeds, news updates and video platforms are frequently full of emotionally stimulating content. Thrilling, unsettling, or extremely captivating information mobilizes the brain and arouses cognition. The mind is more alert rather than being gradually winding down. This mental state postpones the onset of sleep and the deep sleep periods.

The other technological problem of sleep is that of bedtime displacement. There are a lot of people who are planning to fall asleep at a specific moment but have to prolong the usage of the devices by a couple of minutes. These hours often become very prolonged. The pattern slowly changes the sleep patterns later in life and shortens the overall sleeping time. When people are privy to sleep reduction, it will develop with time, and the result will be persistent fatigue.

Sleep deprivation has an impact on cognitive performance. When sleep is lacking, attention, memories, decision-making and emotions control are affected. People can be more irritable, less patient and less resilient to stress. These impacts tend to form a loop and as people become more exhausted, they might also be more dependent on digital stimulation to distract or comfort and this makes their sleeping habits worse.

Sleep fragmentation can also be done by technology. Alerts, night-time notifications and message alerts interfere with sleep cycles. Even partial awakening does not allow the brain to pass full stages of sleep. Short-term fragmented sleep is not refreshing, despite the time in bed appearing to be sufficient.

The healthy digital sleep patterns revolve around establishing a buffer time between the use of devices and sleep. Slowing down the stimulation before the sleep enables the brain to transition to a more relaxed state. Reading, light stretching or quiet reflection are some of the activities that facilitate this transition.

Creating habits of going to sleep helps in building the internal clock of the body. When people retire to sleep and wake up to the same time each and every day, the quality of sleep enhances. Digital practices are supposed to be in line with these practices and not contrary to it.

Sleep is not a luxury. It is a biological necessity. Understanding the effect of technology on sleep will enable people to take some changes that safeguard rest and recovery. A better sleep promotes mental awareness, emotional stability and wellbeing.
