Scientists from Kansas State University studied a number of health markers in both gardeners and non-gardeners, such as physical fitness level, hand strength, bone mineral density, and emotional well-being. They found that gardening not only provided a decent amount of physical activity, but also improved hand strength and sense of well-being.
The increase in hand strength is a given—just think about all of that digging, pruning, and watering. And the boost in mood makes perfect sense. Nurturing living things requires regular attention and plenty of TLC.
Gardening is also a great way to soak up sunshine, which is essential for vitamin D production.
