Blue light hazard, the impact of smartphones on sleep, and their negative effects on health have been extensively researched in recent years. People’s addiction to smartphones in their daily lives and the nighttime use of these devices can disrupt sleep patterns and lead to health problems. Here are some details on this topic:
Blue Light and Melatonin Suppression: Smartphones, tablets, computers, and other electronic devices emit blue light from their LED screens. Blue light suppresses the release of a hormone called melatonin in the brain. Melatonin is a hormone that helps regulate the sleep-wake cycle. Therefore, exposure to blue light in the evenings and at night can affect sleep quality and lead to insomnia.
Sleep Pattern Disorders: Nighttime use of smartphones can disrupt sleep patterns. It can cause problems such as insomnia, difficulty falling asleep, nighttime awakenings, and decreased sleep quality. Disruption of the sleep-wake cycle can result in decreased performance, lack of concentration, and emotional issues in daily life.
Eye Health Issues: Prolonged use of smartphones can also lead to eye health problems. Issues such as eye strain, dry eyes, blurred vision, headaches, and eye discomfort can result from extensive screen use. This is because focusing on close objects strains the eyes and causes excessive strain on the eye muscles.
Attention and Memory Problems: Continuous use of smartphones can contribute to attention deficits and memory problems. Constant interruptions triggered by notifications and social media alerts can lead to difficulties in concentration and decreased memory performance.
Mental Health Issues: Excessive use of smartphones can also contribute to mental health problems. With the increasing use of social media, individuals may subject themselves to comparisons with others, social pressures, and social media addiction. This situation can lead to depression, anxiety, and other mental health issues.
For these reasons, it is important for smartphone users to limit screen time during nighttime, reduce screen usage before bedtime, and pay attention to their sleep patterns. Additionally, creating a dark and comfortable sleep environment can help relax the eyes.
