Neuroscientists say humans can distinguish 10,000 scents, though we don’t have names for a lot of them.
Our sense of smell—the olfactory sense—brings depth and emotional richness to daily life.
Our olfactory system also alerts us to potential dangers: spoiled food, rot and decay, harmful molds. Most Nigerian homes contain a variety of sprays, plug-ins, stick-ons, scented candles, and other products designed to mask or remove bad odors.
Many people suffer allergic reactions to the fragrances in some of these products. Some air fresheners contain toxins.
Yet a few inexpensive household essentials you probably have on hand already—vinegar, salt, coffee, baking soda, hydrogen peroxide—will neutralize most noxious odors around your home and in your vehicles.
