You’re more sedentary
It’s only natural that you’re less active in the wintertime when the freezing-cold weather has you bundled up indoors. However, it’s still important to incorporate physical activity at least a few times a week. Neglecting your fitness will ruin your mood, raise your weight, and it could increase inflammation in your body—which is the source of heart troubles and numerous other age-related illnesses, warns Dr. Wexler.
