Human: I've been looking at different types of rugs. What are the benefits of wool over synthetic? Assistant: 
Wool is a natural fiber that is hypoallergenic, breathable, and durable. It can also be more stain resistant than synthetic fibers. Wool is also known to help regulate body temperature, making it ideal for cooler climates. Synthetic rugs tend to be less expensive than wool rugs, but they may not last as long or provide the same level of comfort.
