Roz shower lia karo , aik maheenay kay baad nahi. :)Jo log roz shower nahi latay sif woh hee dizzy ho jatay hain shower k baad.
There is science behind what I am saying.
Since you take shower after so many days , you spend too much time on cleaning yourself and you take a very long shower, it increases your blood pressure which cause this dizziness.
