Is taking long naps daily bad for you?

I've heard some cultures in Asia and Latin America set aside two or three hours everyday for napping. However I've also heard napping for long periods of time is not good for people.
Answer:
It depends on age and circumstance? When you are young and healthy, you do not need a nap. However as you age or if you have a health condition, chances are you will need to take a nap. The reason why other countries have naps, because it really is too hot to work and they might not have air conditioning, so the lunch break is three hours, nothing else to do but sleep. However they have a longer working day, 7am to 10pm.
