Yes, this is very common, and thereâs a clear reason for it. Screen work tires the brain even when the body hasnât moved. Long periods of focus, constant small decisions, and frequent switching between tasks and notifications all drain mental energy. Add eye strain and sitting for hours, and by evening the âtankâ feels empty. Itâs a real fatigue, not laziness.
That said, itâs worth checking that something else isnât adding to it. Poor sleep, burnout, low mood, or medical causes like low iron,
B12,
vitamin D, or
thyroid problems can all feel exactly like this.
What usually helps:
Breaks during the day. Take a 5-minute break away from the screen every 60â90 minutes. Follow the 20-20-20 rule: every 20 minutes, look at something 20 feet away for 20 seconds.
A switch-off ritual. After work, take a short walk, shower, or change clothes, so your brain gets a signal that work is over.
Avoid going straight from work screen to phone. Scrolling in the evening isnât rest; itâs more of the same load.
Move earlier, not just more. Even 15â20 minutes of physical activity improves energy and concentration.
Do important personal tasks in the morning, when mental energy is still fresh.
Next Steps
Try these changes consistently for 2â3 weeks. If the exhaustion continues, get basic blood tests done through a physician. If you also notice low mood, loss of interest, irritability, or poor sleep, consult a psychologist. Ongoing exhaustion can be an early sign of burnout or depression, and both respond well to timely support.
