If you find it difficult to choose simple things, like what to watch on TV, or if you feel extremely irritated by basic questions, you are likely mentally exhausted.
3. Does sleeping well completely solve the problem?
Sleep is essential for replenishing cognitive energy, but if your daily routine remains overloaded with pointless choices, exhaustion will quickly return the following day.
4. Can children also suffer from this type of fatigue?
Yes, especially in environments with excessive stimuli or when they are forced to make many decisions on their own, which can result in crying spells and impulsive behavior.
