I generally try to go offline to relax. I am online at work and my eyes are sore at the end of the day. So I listen to the music in the kitchen, cook for me and friends (it's almost a meditation for me, really) or I go for a long walk in the forest near my house.
I used to go for a walk on the seaside but now my family moved to another city and there are no beaches here. I miss that a lot. Drinking a glas of wine on the seaside, listening to the sounds of the nature - that was the best way to relax for me.
