According to the American College of Allergy, Asthma, and Immunology (ACAAI), a good spring cleaning can help you breathe better. If you're prone to allergies or have an asthma attack, don't assume that pollen is the main culprit. Potent asthma triggers, such as dust and pet dander, float in small streams of air and settle on all surfaces in the house. A thorough cleaning of the house can help eliminate allergens and prevent new ones from entering.
And when you feel better physically, it's easier to relax. Spring cleaning started out as a way to clean up the mess of winter. In those days, houses were heated with fire and doors were kept tightly closed to keep warm air inside. This, of course, caused soot and grime to accumulate during the cold months.
Nowadays, with modern heated homes, this type of cleaning is no longer necessary. There is no documented medical evidence that spring cleaning is a must; rather, it seems to be rooted in tradition more than anything else. While spring cleaning in the West is carried out loosely and collectively, in Iran it is much more codified. Every year, public service campaigns are organized for everything from the proper disposal of old-fashioned medicines in the United States to the disposal of garbage from the Irish countryside.
