How do you manage distractions while working from home?

Create a space for work and stick to it. Only way I can do it.

Music and also a separate space for work help to focus and manage distractions.

You gotta have different environments for work and play. If you can't do that, when entering "work mode" I find what helps is switching some parts of my environment (different keyboard, turn on desk lamp, etc.)

In our company, everyone works remotely and we have no problems with productivity

I split work into 45 minutes sessions. During a working sessions I don't check any external communications like slack or email. I focus on a single task. I tell myself, what if went for a long shower. Nobody dies if I don't answer within 45 minutes. That gives me mental permission to disconnect from everything. And it turns out nothing bad happens. The world can wait. After each session I make a 15 minutes break to move and exercise. I can check communication apps. If there is something urgent, I can plan my next working session according to that. If not, I just move on with previously planned work in the next session. A few years ago I wrote an article where I shared my productivity tips https://medium.com/swlh/js-devel...

I'm still looking for a way to avoid this :)

Amm, yeah it's difficult but also it's kind of a habit to allow yourself to indulge in distractions which can be changed with practice and small steps at a time like using Pomodoro techniques.😊

I am personally on my own and I don’t have door to my room. So I put a couch in front of my laptop and dedicate it to work only. Then I say if I want to do something else, I can’t use my laptop, I use my phone. It works for me most of the time.

Allocate specific locations directly related to work and other to rest, that way you don't get overwhelmed with home becoming your workplace and you also associate it with focus.
