Most people say that a 2-hour nap is too long. They claim that you will feel groggy and disoriented after waking up from such a long nap. However, there are some benefits to taking a 2-hour nap.
For one, you will be well-rested and can better focus on tasks at hand. A 2-hour nap can also help improve your mood and increase your alertness. It is important to note, however, that napping for too long can lead to sleep inertia - a feeling of grogginess and disorientation upon waking up. This is why it is generally recommended to keep naps short (30 minutes or less).
