When choosing, consider:

* **Your typical target audience:** Are they beginners or more knowledgeable about sleep?
* **The content of your posts:** Does your blog primarily focus on solutions, benefits, or general information?
* **SEO considerations:** You can also work in related keywords, but focus on user readability first.

I recommend choosing the description that best reflects the content relevant to this tag. For general use, Option 1 or 2 are good, while for focusing on solutions, Option 3 is a good choice.
