Scientists have linked scent and long term memory in a study conducted by the American Psychological Review. A simple scent like buttery popcorn can remind us of a movie theatre or passing a woman with a certain fragrance makes us remember a childhood memory of our mother or grandmother. Each whiff provides a link to a memory. A certain combination of smells can become a link to recall the scent of your bedroom at bedtime.

Finding the right mix of scents is what creates better slumber. A study in 2019 found that bad odors and good odors (like the smell of flowers) exist in the olfactory system in our brains. A bad odor (like tobacco smoke) can actually deter a restless sleep while good scents provide more energy when we wake up. The study in the Journal of Post-traumatic Stress even found that good scents provide deeper sleep and healthier dreams.

While sleep is quite integral for each person’s well-being and holistic health, it doesn’t come effortlessly to most people. It's quite tiresome and saddening to toss around in bed all night only to reach the morning time more tired, grumpy, and irritable.
