The impact of scents on our mood and emotions is something truly remarkable. Have you ever noticed how the earthy fragrance of rain or the crisp scent of pine in mountain air can swiftly calm your mind? It's a reminder of the profound influence that our sense of smell has on our overall stress-levels, senses, memories and emotions.

Key Essential Oils for Anxiety Relief
Lavender essential oil is known for relaxing the nervous system. Inhaling lavender essential oil reduces anxiety-related heart rate and blood pressure, according to research. It helps soothe and lessen anxiety. The relaxing, flowery aroma of lavender may decrease hyperactivity in the amygdala, which controls emotions and is linked to anxiety. Consistent use of lavender essential oil may strengthen the link between the aroma and peace.
Peppermint is renowned for its invigorating properties. The menthol content in peppermint oil provides a refreshing and cooling sensation. Inhalation of peppermint oil may stimulate alertness and enhance cognitive functions. Its crisp aroma is known to alleviate mental fatigue and increase focus. Additionally, peppermint oil may contribute to relieving tension headaches and promoting a sense of revitalization.
Eucalyptus is celebrated for its respiratory benefits. Inhalation of eucalyptus oil may help clear congestion and promote easier breathing. The camphoraceous aroma of eucalyptus oil is often used to provide relief from nasal congestion and sinus discomfort. Known for its soothing effects on the respiratory system, eucalyptus oil is a popular choice for aromatherapy during times of respiratory distress. Its fresh and clean scent is associated with a feeling of clarity and ease.
How-to Use Essential Oils Safely
Dilute Properly
Before applying these oils to your skin, essential oils must always be diluted due to their high concentration.
For routine adult use, essential oils must be diluted to a concentration of 1-3%. This is equivalent to six to fifteen droplets every 2 tablespoons of carrier oil.
Do a Patch Test
Perform a skin patch test before usage to check for irritation or allergies.
Wait 24 hours after applying a diluted drop to the inner arm. If there is no redness or irritation, consider the oil is safe to use.
Use Proper Inhalation
Add 2-4 drops of essential oil to diffuser water. Diffuse for 30 minutes or less. Make sure your diffuser disperses a fine mist.
The smell may be inhaled immediately from the bottle. Open and hold the bottle 2-3 inches from your nose. Slow, deep breathing for 1-2 minutes. Close your eyes and inhale to relax.
Add up to 5 drops of diluted essential oil to warm bath water for aromatherapy. Breathe deeply and soak for 15-20 minutes. The warm water diffuses aroma.
Inhale with a handkerchief or tissue, but avoid skin contact near the nose or eyes, as undiluted oils might irritate.
Apply 1-2 drops to hands, massage together, cup over nose, and inhale deeply for breathing issues.
Talk to Your Doctor
If you are pregnant, breastfeeding, taking medication, or receiving treatment, ask your doctor before using this product.
Asthmatics and epileptic sufferers should avoid certain oils.
Consult with a herbalist or aromatherapist regarding the properties and safety of the oil.
Dilution, skin testing, and controlled inhalation help you utilise essential oils safely.
