Fatigue is a feeling of exhaustion that does not get better with sleep. It can be physical or mental/cognitive fatigue. Fatigue can change at different times and isn’t the same for everyone. Tasks that used to seem easy to you might now be a challenge, and this can change throughout the day or week by week. You might even feel low in motivation. Remember, it is ok if you can’t achieve everything that you wanted to in that day.
Physical fatigue: Feeling low in energy, your body may feel heavy and you may feel like you have lost a lot of strength. Even small tasks, like walking to the bathroom, might take up a lot of energy.
Mental/cognitive fatigue: Your brain might feel foggy or cloudy, with even simple tasks exhausting or difficult. You might find it hard to concentrate and focus on work tasks.
