Hi @okunlolayk. Good topic for discussion and I concur with the fact that a good night sleep, despite it taking a quarter time of my day, is the most important thing to lead a healthy and productive life. I would like to point out a few things which you can implement, if you think it would be worth it, in your next article:

• When you were explaining the stages of sleep, everything is cramped into a single paragraph which makes it hard for readers if they ever need to refer to a specific point. You did make the subheading bold but I would suggest you do it in a separate paragraph, or better, make a bullet point. No matter how much information you provide in your article, it wouldn't be complete without a proper adjustment.

• There are some typos and grammatical errors, here and there. Might I suggest you use Grammarly or any other online-based grammar application? It would certainly make you look good by minimising your grammatical error and probably used some variety in words.

• One of your images was taken from Venngage. I'm not sure regarding their policies of copyright material, but you should consider checking them before doing anything to prevent future complication.

Please note that I'm not in any way, try to disapprove your work. You've done an excellent job here, but you can make it better.
