Hello Gulshan!
You touched upon a very important topic - the optimal organization of the developer's workplace.
I also work remotely, but it seems to me that both those who work in the office and those who work remotely - the principles of proper organization will be the same.
A couple of pieces of advice that I can give from myself:
A good big(!) monitor is a must. Even if you work on a laptop, connect an external monitor to it. Your eyes will thank you! If not now, then in a couple of years 
And get into the habit of getting up every half hour and just walking around. Ideally, you can do a little warm-up, but even just getting up and changing your position will be good. The thing is that when we sit in one position for a long time, it is very harmful to our spine.
In order not to forget to do a warm-up, you can either install some application on your computer, or use, for example, a smart watch.
