Why do we feel tired despite having done nothing?

Our days sometimes end with a clear sense of exhaustion, even though we haven’t exerted significant physical effort. One possible reason for this is digital fatigue; the constant stream of notifications, frequent switching between apps, and continuous content consumption throughout the day drain human energy in a subtle, often unnoticed way. The effects of this fatigue are not limited to feelings of tiredness; they extend to the body. Prolonged periods of sitting in front of screens, lack of movement, and continuous device use can increase muscular strain, leading to neck and back pain, as well as eye strain resulting from prolonged staring at screens. Psychologically, constant exposure to screens can scatter attention and impair concentration, while continuous digital communication raises stress levels and makes relaxation more difficult. These pressures can also affect sleep, trapping individuals in a cycle of stress, disrupted sleep, and daytime fatigue. Although technology has made communication with others easier, excessive screen-based interactions can heighten feelings of isolation and loneliness. Moreover, the persistence of work and message responses outside working hours gradually blurs the boundaries between professional and personal life, encroaching on time reserved for family and social relationships. Digital fatigue can be mitigated by redefining our relationship with devices and allowing the brain regular breaks away from screens. Additionally, setting aside time for genuine face-to-face interaction with family and friends, and avoiding content that triggers anxiety and stress, can help restore a sense of calm and balance. Thus, fatigue is not always the result of a day filled with physical activity; sometimes, sitting in front of a screen all day is an effort in itself.
