Have you ever heard of sensory adaptation? This is the phenomenon where our brain tunes out any constant stimuli. So, for example, if you are in a noisy environment, after a while you will stop noticing it, or if you are exposed to bright light, your eyes will adjust and things will begin to look normal again.
So it is often a very useful capacity to have. But not always! Ever wonder why smelly people never do anything to change matters, like wash their clothes or wear deodorant? This is usually because they don’t even realize they smell. Their brain has stopped noticing their odor. The same is true of our houses. Each of our homes has a specific smell, sometimes pleasant, sometimes not, which we become so used to that we don’t notice.
So, it is important that we use air fresheners in our homes, so that guests don’t detect a nasty odor that we are immune to! But air fresheners are expensive to buy. Luckily, there is a cheap and easy-to-make alternative. Here’s a video detailing how to make your own air freshener with minimal effort.
