I don't care for the heat either. I usally get better with the blues in summer though, because as a parent this time of year the stress seems to lessen. Though when it gets humid the AC becomes my best friend and I should get out more! Maybe if u sat out only a couple of minutes a day it would help. A friend of mine gets sun therapy. Yes skin cancer is a concern but we need 10 minutes of sunny light to process Vitimin D. A little sunscreen and it can help! Take Care!!
