December is often a month wherein many people tend to hibernate in tightly sealed homes, eating more and doing less. Getting outside, moving and getting your blood pumping boosts positivity; which is particularly important in the wintertime. The December cold makes the body work harder to stay warm, which raises the metabolic rate. Outside colder air is an easy way to boost your metabolism.
Getting outside and moving helps lungs to detox, the brain to think clearer, releasing serotonin and dopamine, and reduces anxiety.
Studies have shown that interacting with nature improves your cognitive function no matter the weather. A few minutes every day in a pergola increases overall satisfaction with where people live.
