Why does this happen and how should we use it to our advantage?

I'm almost exclusively a tournament player. I play STTs and an occassional MTT(usually about 4-5/week) full time online.

Anyway, been running really badly last few days. And even though I'm in a good mood and still playing well, I just can't seem to shake it.

So I switch up and go play in the $2000 NL ring games. Multi table 6 of them for about 3 hours and wind up winning about $3500.

Now, I have no doubt that a lot of luck was involved, and perhaps it could just have been a coincidence. But what is it about changing games that can refreshes a player so much? And, more importantly, how should we exploit this? Should one regularly schedule different games in periodicly? Or should one switch games as soon as a bad run begins? Or should one wait until a prolonged losing streak hits then switching up?
