If the individual is not a health professional, this should be made evident. Some information on the internet is intended for professionals and is, consequently, difficult to make sense of. Regardless of who the information is for, the intended audience should be explicitly stated.
Some information is purely anecdotal.
In other words, someone has had personal experience with something and they are then saying that everyone can have that same experience. This is the least reliable or valid of any information you will read. What is true for one person may not be true for you or another. Some information is based on generally accepted practice guidelines. For example, yoga and meditation are generally accepted as effective forms of relaxation.
