The 'Ice-Cold' Bedroom Scent That Instantly Tricks Your Brain Into Feeling Cooler on Humid May Nights
Certain notes instantly relax your mind and body on hot and clammy nights
It's no secret that scent is one of the most evocative senses. From light, bright, florals that lift your space in spring, and cooling mint to refresh you on humid May nights, the right fragrance can do more than just set the mood.
In fact, say our home fragrance experts, some scents can actually make your space feel cleverly cooler.
Here, they explain which specific notes to use to make your bed feel cool in summer, and exactly why they work.
It's important to note that no scent is going to actually cool down a bedroom fast and physically reduce the temperature. But, as Jennifer Pressimone, internationally recognized Clinical Aromatherapy Expert, Author, Formulator, and CEO at JennScents and Aromaversity, explains, diffusing cooling scents in the bedroom can help you to sleep better.
'The top main culprits behind sleep issues that I see with clients are stress, anxiety, overwhelm, and burnout,' she explains. 'This causes mental chatter, ruminating thoughts, frustration, and irritability, all of which are heat-triggered emotions.'
So, she advises that, in particular, peppermint and spearmint are among her favorite 'heat reducers,' along with Roman chamomile, lemon, and ylang ylang. 'Their chemical make-up helps lower the physiological and psychological thermostat, providing a cooling sensation,' she says.
'The menthol content in peppermint, for example, binds directly to certain receptors in your skin and mucous membranes, which send a signal to the brain to cool down.

'You’ve heard the saying, “Don’t go to bed mad." The premise behind this is that heat-triggered emotions can keep your sympathetic nervous system on high alert.
To give you a visual, it would be like doing cardio exercises, then trying to go to sleep immediately after. You’ve stimulated circulation so much that you need a buffer to calm your nervous system down.
'When you don’t, it causes mental chatter, anxiety, and nervousness. This is the power scent has when you smell the right ones. It moves you into a calm, cool, and collected state.'
How to Use Cooling Bedroom Scents
Avoid the flicker of flames to make your space feel cooler.
To use these cooling scents, Jennifer advises against using your best candles or anything with open flames, which can work to make your space feel psychologically warmer and burn off some therapeutic benefits. Instead, she says, use your best essential oil diffuser (my favorite is the NEOM Wellbeing Pod Luxe) or a room spray to get the best scent therapy benefits.
'Scent inhalation, of course, is my first choice of use,' she adds. 'It has been scientifically shown to be the best route to create the quickest physiological and psychological effect.
'When you inhale a scent, it goes instantly to your emotional and memory center, bypassing your logic region, or what I call your overthinking region. This means your body can calm down faster than you can complete a blink.'
For topical application, Jennifer also recommends combining cooling essential oils, such as peppermint essential oil, available at Walmart, with a carrier oil such as sunflower or jojoba, to further help your body reduce heat.
'For example, a combination of Roman chamomile, peppermint, and ylang ylang emulsified in sunflower oil, and applied to your wrists, the crease of your arm, and the bottoms of your feet, can calm physical heat, as well as emotional heat,' she shares.
