As Mike pointed out, room humidifier is the most important thing to have. Some cases have a hygrometer inside them. When you carry your guitar with you, you don't want it to stay in a very cold or hot place for a long time. You can also cover the body of the guitar in a bag and then put it in a hardshell case to make sure the humidity change would affect it less.
