Spring cleaning is a progressive process of cleaning starting from the first few days of spring, when the weather begins to warm up. It usually involves cleaning the whole house from top to bottom. Generally, the warmer weather makes it possible to open the windows and doors, allowing fresh air to circulate while cleaning, especially went it comes to dusting. Because it's early in the warm season, there may also be fewer bugs. This also helps to cool down the body when working up a sweat while cleaning, but you can always do your cleaning butt naked to keep cool.
