Man and blue light: The influence of screen light on our health

The article considers the impact of blue light emitted by electronic screens on human health. Due to the progressing digitisation and the increasing use of electronic devices such as TVs, smartphones, tablets or computers, this topic has become particularly relevant. The article discusses the results of the latest scientific research on the impact of blue light on our health. Short-term as well as long-term effects of blue light exposure were analysed. The results of these studies indicate potential detrimental consequences for our sleep, eye health and general well-being. After an in-depth study of the topic, it was found that blue light emitted by electronic screens can disrupt our natural sleep rhythm by inhibiting the secretion of melatonin, the hormone responsible for the proper functioning of our “biological clock”, supporting the regulation of the circadian sleep-wake cycle, thanks to which the body knows when it needs to go to sleep and when to get up. Nighttime exposure to blue light can lead to difficulty falling asleep, sleep disturbances and general daytime fatigue. In addition, prolonged exposure to blue light can have a negative impact on eye health, contributing to visual fatigue, irritation and an increased risk of developing eye diseases.
