I knew fresh air is good for those with Dementia, as well as exercise. However, it can be hard to get a 94 year old with Dementia to do somethings. This weekend, I manage to get my mother to sit with me on our front porch. To my surprised, we enjoyed the fresh air for 5 hours!!! Sundowning was almost non existent and she went to bed with no problem. Got to get more of that fresh air!
