The first step is important and well studied. Double your results with exercise by doing it outside. Again, it's well studied that being with nature improves your mood, so why not take a hike through the woods or along a river? Put your phone away, leave the earbuds at home and just focus on the moment.

From time to time, when the weather is good and everyone's still asleep, I'll take a hot cup of tea outside to the woods near my place and sit on a fallen tree and just be quiet. It improves my mood all day. I did it during the first snowfall of the year during covid and could hear the snowflakes hitting the leaves. I could still hear the yelling from inside the house, but somehow it was not my problem in that moment.
