Clutter is a major contributor to less-than-ideal mental health. According to the DSM-5 (the handbook used by mental health professionals), cluttered spaces can lead to decreased motivation and energy, which are symptoms of depression. In addition, clutter can block your doorways and cause fire hazards. Not only does keeping your living space clutter-free make your home more comfortable and safer, but it's also a great way to keep yourself healthy and happy.
