Caffeine isn't really beneficial for work, right? Most of its effect is because it's addictive and you need to prevent the withdrawal. The point of a break is that it's an excuse to stand up and walk around.

True, the coffee is just one of the devices to take your mind off things. My ex-girlfriend had a dog and when she was sick I had to walk it 3 times a day. Even though by that time (shortly before our breakup) I didn't like her or her dog, the walks were extremely therapeutic.

All coffee and smoke breaks actually are aimed at taking a step back and gain some small extra energy to keep going.

I agree. And its value and time commitment needed does not change if you work from office or home.

You should definitely stand up and walk around even when working from home.
