Well, for some people, their eyes will be puffy when they get up in the morning. And of course, that will be annoying and ugly. Generally speaking, there are many reasons which can cause puffy eyes, including allergies, irritants, chemicals, depression. If your puffy eyes are caused by those reasons, you need to go and see the eye doctor. But on the other hand, according to some researches, if you drink too much water when you sleep the last night, it is also possible to have puffy eyes. At this moment, in my opinion, you should not drink too much water before sleeping. Also, having some cool teabags under your eyes will be effective too.
