In addition to sleep quality, I also look for information on how to use these products. You can use this website to find information and make an informed decision. I have compiled a list of links to sleep products that I think will help you make good choices.
There are different kinds of sleep. Most people need both "quiet sleep" and "light sleep." The term "light sleep" is used by doctors to refer to sleep that is too easy to fall asleep in the morning. Light sleep can also be defined as falling asleep in the middle of a two-hour nap and then having a normal night's rest. The most common problem people report is not having enough rest between naps. Sleep hygiene should be practiced to reduce the risk of accidents. Some people need a longer nap at night so they can have their naps more easily. If you are trying to make good sleep choices, you are probably better off using the "quiet sleep" or "light sleep" sleep. If you are a medical doctor interested in sleep, I strongly urge you to read my book and recommend it to your colleagues. You can order it from your local bookstore, or you can use my affiliate link. Your book will be of interest to people like me.
