Sometimes we feel we are still strong even though we only sleep for a few hours. Even though you sleep, your body and brain carry out many recovery processes.
Lack of sleep can make it more difficult for us to focus, get sleepy easily, and make our mood messy. If it happens frequently, the impact can also be more serious for health.
So if your body is giving you a signal that it's tired, don't keep forcing it. Rest is not a waste of time, but part of keeping your body fit.
