Psychologist Reveals: Why 2021’s Candle Trends Are Good for Our Health

Written by  Jan 16, 2021

It’s no surprise that many people use candles as a form of self-care - certain scents are proven to impact our mood by making us feel more relaxed, joyful, or even energised. And recently, candle making trends took over TikTok which led searches for 'soy candle making kits' to increase by 3,500%!

So, with Blue Monday on its way (18th Jan), OnBuy’s Health and Beauty Department investigated how candles can affect us psychologically, and which of our favourite candle trends are looking most popular in the year ahead.

OnBuy exclusively spoke with Lee Chambers, psychologist and wellbeing expert, who explains how candles can boost our mood when stuck inside.



"As humans, our olfactory system has a close relationship with our brain, and therefore certain scents can impact our mood. This is particularly powerful as we associate smells with experiences, which come with attached emotions. Because our olfactory system is linked to the areas of the brain that deal with learning and emotions, scents can also directly impact how we feel. While part of the benefits come from a psychosomatic belief, and our memories of experiencing the scent previously, studies have shown that citrus notes can energise us and elevate our mood, floral fragrances can promote elements of joy and a feeling of being grounded, and lavender brings a relaxed feeling of serenity.

With the continued working from home situation, have a think about incorporating scented candles into your home office or educating space. If you want to be more productive, go for a citrus or mint-based candle. If you are expecting a stressful day, lavender or jasmine can take the edge off and keep that calm confidence flowing.

While it is important to light candles in the room you are occupying for the impact of the scent, it’s important to consider the use of the room and the scent you are using to ensure you get the desired benefit."
