The Science Behind Scents: Exploring Aromatherapy and Scented Candles

Scented candles have long been a popular home accessory, but did you know that they can also have therapeutic benefits? In this article, we will explore the science behind scents and aromatherapy, and how different scents can be used to improve your mental and physical wellbeing.

What is Aromatherapy?

Aromatherapy is the use of plant-derived essential oils to promote physical and psychological wellbeing. These oils are extracted from flowers, leaves, stems, and other parts of plants through a distillation process. When inhaled, the aroma from these oils can stimulate brain function, affecting the body’s physiological responses.

How Does Aromatherapy Work?

The scent of essential oils is believed to trigger the limbic system in the brain, which is responsible for regulating emotions, memories, and the autonomic nervous system. This system controls unconscious bodily functions such as breathing, heart rate, and digestion. The limbic system is also linked to the endocrine system, which is responsible for the production and regulation of hormones. By inhaling essential oils, these systems can be stimulated, which can lead to various physiological and psychological benefits.

Scented candles can be an easy and convenient way to incorporate aromatherapy into your daily routine. When burned, scented candles release essential oils into the air, which can be inhaled to produce the same therapeutic benefits as using essential oils directly.

Choosing the Right Scented Candle

When choosing a scented candle for aromatherapy, it is important to select a candle made from natural ingredients, as synthetic fragrances can be harmful and produce adverse effects. Look for candles made from soy, beeswax, or coconut wax, and scented with pure essential oils.
