Make sure your children spend more time in and among plants and trees if you want them to develop a stronger resistance to disease.
When daycare workers in Finland “rolled out a lawn, planted forest undergrowth (such as dwarf heather and blueberries), and allowed children to care for crops in planter boxes,” something fascinating transpired: the microbes on the kids’ skin and in their gastrointestinal tract improved in a very short amount of time. This “supports the hypothesis that exposure to nature protects immune system illnesses such autoimmune diseases and allergies,” This implies that a child doesn’t necessarily need to be playing outside in nature to reap these benefits; instead, “greening” the areas where kids spend time, wherever those areas may be, could have a big positive effect on their immune systems. Families should consider how much time their children spend in green places if they wish to help their children develop better immune systems.
