The Impact of Temperature on Scent Perception

Have you ever wondered why suddenly you cant smell your beautiful wax melts when you’re in a cool room, or the scent seems more subtler… ?

If you’re not smelling your wax melts as well as you used to, it’s probably because the air temperature is a little lower than optimal.

It turns out that scent molecules move slower when the air is cold, which means that our noses are less effective at detecting the scent of your wax melts.

In fact, researchers have found that olfactory receptors bury themselves a little deeper in our noses in winter months—possibly as a protective response against dry, cold air.

Diffusion (in gases) is the phenomena in which the scent vapour particles mixes with air.

Diffusion is directly proportional to temperature.

Well, here’s the trick: turn your heating up a little notch, warm your room and awaken the air molecules, remember fragrance needs warmth for you to smell the scent.

Air is made up of molecules of gases. The molecules of gases are jingling.

Heating up of molecules increases the jingling. These jingling molecules gets dispersed around the air more easily.

Cold molecules jingles at a slower rate. Therefore, scents and smells aren’t dispersed around the air as well as we want it to.

It’s the same reason why the dustbin lorry leaves behind the strongest of smells on hot summer days.

So if you want a cosy afternoon with your wax melt on, turn your heating up a little notch, warm your room and awaken the air molecules, remember fragrance needs warmth for you to smell it.
