If you regularly work from home, the 3 pm slump might be a familiar feeling. It's actually an entirely natural dip in energy, caused by your circadian rhythm and an increase in melatonin, commonly known as the sleep hormone.
It's usually staved off with a brisk walk, a cup of coffee, or a snack, but there's one simple trick that home fragrance experts recommend instead – and all you need is an electronic oil diffuser and some lemon essential oil, available at Amazon.
Here, they explain just how using some of the best home fragrances can keep you alert, awake, and help you to beat that afternoon crash without caffeine or sugar.
How Aromatherapy Works to Improve Cognitive Focus
As Jennifer Pressimone, internationally recognized clinical aromatherapy expert, author, formulator, and CEO at JennScents and Aromaversity, explains, 'The reason scent therapy is so powerful, especially for brain health, is because it is your only sense that bypasses the logic regions. Meaning, when you inhale a scent, it provokes an instant response in your brain and body, before you can overthink or judge it.
'Scent connects with your limbic system to activate the emotion and memory centers. This stimulates cognition and helps reduce mental fatigue.'
In terms of the best mood-boosting aromas for beating that afternoon lull citrus scents, like lemon, are the way to go.
'Lemon, Citrus limonum, sharpens focus, concentration, and mental clarity while inspiring creativity, articulation, and accuracy in your brain performance,' continues Jennifer. 'It has also been shown to inhibit neurodegenerative conditions.'
Darlene Killen, who is a member of the Alliance of International Aromatherapists (AIA) and the National Association for Holistic Aromatherapy (NAHA), and the founder of MoonInMental, agrees.
'Lemon essential oil improves working memory per electroencephalogram research and is the mildest entry point for daytime use,' she adds, referencing the diagnostic test used to record the brain's electrical activity.
'Lemon balm is the most underused option for cognitive work. It supports calm alertness rather than stimulation, making it especially effective for extended focus tasks and for people whose attention struggles under pressure rather than under stimulation.'
Therefore, using lemon essential oil, available at Amazon for just $10, is a simple way to make your home workspace more productive. If you do not have one of the best essential oil diffusers, you can pop a few drops on a cotton wool ball and place it nearby.
Adding a fragrance-free carrier oil, such as fractionated coconut oil from Amazon, will increase the longevity of those few drops. This is a really simple way to make a bathroom smell luxurious, so it absolutely works beyond your home office.
How to Use Lemon Essential Oil to Improve Cognitive Focus
The simplest way to enjoy the benefits of lemon essential oil is by using your best essential oil diffuser – the NEOM Wellbeing Pod Luxe is my personal favorite.
'Inhalation of an essential oil’s scent has been scientifically proven to be the most effective way to elicit physiological and psychological responses,' explains Jennifer. 'When scent enters through the nose, it activates the limbic system to help you regulate emotions, memories, and stress.'
Simply add five to eight drops of lemon essential oil into a diffuser and run for 30 to 60 minutes, right around 3 pm, as an effective way to boost brain power, alertness, focus, and concentration.
'Avoid continuous diffusion as olfactory adaptation reduces the effect over time,' adds Darlene.
Alternatively, for a non-electric option, you can also mix in five to six drops of essential oil to a four-ounce jar of Epsom salt, available at Amazon, or sea salt.
'Let the jar sit on your desk or counter with the lid open,' advises Jennifer. 'This offers a great aromatic experience. Seal the lid on the jar after 30-60 minutes, and reuse this “smelling salt” for five days.'
