Take at least one hour consecutive walk every day without any gadgets. It'll give your brain time to recover and your body exercise to releave stress.

+1 for walking. I am a pathological walker. If I am having issues (stress, concern, overwhelmed) I walk for a few hours. I can't say it always works but it gives me something constructive to do and allows me to focus less on my immediate problems that I often can't change.
