My first source is from SlumberWise which is an independent website about sleep and other things related to sleeping. This is a secondary source because they are pulling information together from other sources to create the article. The article is about siestas and the history of them. It is a vanity publication on a website on the topic. It was written by the authors of SlumberWise and are qualified to write about this topic because their site is about sleeping and other information related to it. It also has links that lead to their sources of information. The information could be slightly biased since their website is mainly about sleep. Overall, I think it's a decent resource. It is reliable but not to the most reliable as some other sources.
