One of the things that I have learned is that being outside provides a natural source of vitamin D. I suggest watching some of the farm and garden channels like Doss Acres as they often talk about the need for vitamin D and just taking in the sunshine. I won't go into a lot of detail, but there have been a lot of studies that indicate that being outdoors lifts out moods, and let's think about this...proper exercise also improves our health and lifts our spirits. And I have to be honest...I volunteer at a local cemetery that was established in 1843. When I walk through the cemetery, I see history...I see art...I see architecture and I receive peace and joy in a place where some would see sorrow.
If you find yourself suffering from cabin fever, dealing with a loss, or just needing a change...try going outside and see if that helps. One caveat: if you think you need help, don't hesitate to reach out to someone. Call a friend or family member, talk to a minister, a counselor, a psychiatrist...someone...and get help.
Happy Gardening!
