It might sound a bit surprising but my recommendation would be two things.
1. A short period of exercise after arriving home, the more strenuous the better, but even a 10-15 minute walk in silence will help a lot. Exercise although not physically relaxing relaxes the mind and reduces the stress caused throughout the day, it also ensure a good nights sleep. if your mind is clear relaxing becomes very easy.
2. Find a hobby or something you love that you can completely lose yourself in. I love guitar myself, I can completely forget the world for hours at a time while playing. Find something you love an just throw yourself at it. TV's ok, but you don't grow any, it just make you dull.
