Fényersséget

Fényersséget, or "light fatigue" in English, refers to a state of mental and physical exhaustion caused by prolonged exposure to artificial light, particularly blue light emitted by digital screens such as smartphones, tablets, computers, and televisions. This phenomenon has gained attention in recent years due to the increasing reliance on electronic devices in daily life.

The symptoms of fényersséget can include eye strain, headaches, difficulty focusing, irritability, and disrupted sleep patterns. These effects are often linked to the way blue light suppresses the production of melatonin, a hormone that regulates sleep cycles. Additionally, the constant stimulation from screens can lead to cognitive overload, contributing to mental fatigue.

Fényersséget is not recognized as a formal medical diagnosis but is commonly discussed in the context of digital wellness and ergonomics. To mitigate its effects, experts recommend reducing screen time, especially in the hours leading up to bedtime, and using features such as night mode or blue light filters on electronic devices. Proper lighting in work and living spaces, along with regular breaks from screen use, can also help alleviate symptoms.

Some studies suggest that individuals who spend extended periods in front of screens may experience long-term effects on their sleep quality and overall well-being. While more research is needed to fully understand the implications, awareness of fényersséget encourages healthier digital habits and a more balanced approach to technology use. Simple adjustments to daily routines can promote better eye health and mental clarity.
