Aromatherapy is a holistic healing practice that uses natural plant extracts, known as essential oils, to promote physical and emotional well-being. These aromatic oils are derived from flowers, leaves, bark, stems, and other plant parts through processes like steam distillation or cold pressing. Aromatherapy can be applied via inhalation, massage, or topical application and is widely recognised for its ability to reduce stress, enhance relaxation, and support overall health.

As the elderly population grows, interest in complementary therapies like aromatherapy has surged, given its potential to address common issues such as anxiety, insomnia, pain, and cognitive decline.

History and the use of aromatherapy in eldercare

Aromatherapy dates back thousands of years, with origins in ancient Egypt, China, and India, where aromatic substances were used in religious rituals, medicine, and cosmetics. The modern form of aromatherapy emerged in the early 20th century when French chemist René-Maurice Gattefossé coined the term. Since then, its popularity has steadily risen as an alternative or complementary therapy in healthcare settings, including eldercare.

In eldercare, aromatherapy has become an increasingly adopted practice in nursing homes, hospices, and home care settings. It is valued for its gentle, non-invasive nature, making it particularly suitable for addressing the unique challenges faced by older adults.

Different types of aromatherapy

Common essential oils that are suitable for the elderly

Not all essential oils are safe for elderly individuals due to their delicate skin and potential health conditions. The following are particularly suitable:

Lavender: For relaxation and improved sleep.
Rosemary: To boost memory and cognitive function.
Peppermint: For relieving headaches and nausea.
Chamomile: To reduce anxiety and promote relaxation.
Eucalyptus: To ease respiratory issues.

Benefits of using aromatherapy for elderly

Non-invasive and gentle
Aromatherapy offers a soothing and non-invasive alternative to traditional medical interventions. This is particularly important for elderly individuals who may have a lower tolerance for invasive procedures or harsh medications.
Stress and anxiety relief
Essential oils such as lavender and chamomile are well-documented for their calming properties, helping to reduce anxiety and promote relaxation in older adults. This can be particularly beneficial in managing conditions like dementia or Alzheimer’s disease, where agitation and anxiety are common.
Pain management
Aromatherapy has shown promise in alleviating chronic pain conditions, such as arthritis or neuropathy, which are prevalent in the elderly. Massages with essential oils like peppermint or eucalyptus can provide localised pain relief and improve mobility.
Improved sleep quality
Sleep disturbances are common among the elderly, often exacerbated by anxiety or physical discomfort. Oils such as lavender or bergamot can help induce sleep, contributing to better overall health.
Enhanced emotional well-being
The sensory stimulation from pleasant aromas can elevate mood and reduce feelings of loneliness or depression, which are common in older populations.
Holistic benefits
Aromatherapy addresses not just physical symptoms but also emotional and mental well-being, providing a comprehensive approach to care.

Challenges of using aromatherapy for elderly

Risk of allergic reactions
Elderly individuals often have thinner, more delicate skin, making them more susceptible to irritation, rashes, or allergic reactions when essential oils are applied topically. Proper dilution is critical to mitigate this risk.
Respiratory sensitivities
Inhalation of certain strong aromas may exacerbate respiratory conditions like asthma or chronic obstructive pulmonary disease (COPD), which are common in the elderly.
Potential drug interactions
Some essential oils may interact with medications, potentially reducing their efficacy or causing adverse effects. For example, oils like grapefruit can interfere with the metabolism of certain drugs.
Cost and accessibility
High-quality essential oils can be expensive, and consistent use may strain budgets, especially in care facilities. Additionally, not all caregivers may be trained in aromatherapy, limiting its accessibility.
Variable efficacy
Aromatherapy’s effectiveness can vary greatly among individuals due to differences in preferences, sensitivities, and underlying health conditions. What works for one person may not yield the same results for another.
Overuse and dependency
Overexposure to essential oils can lead to desensitisation, diminishing their effectiveness over time. Dependency on aromatherapy for relaxation or pain relief may also overshadow other necessary therapeutic interventions.

How to introduce aromatherapy to elderly?

Start with education
Educate the elderly individual and their caregivers about aromatherapy, its potential benefits, and how it works. Address any concerns they may have, and ensure they feel involved in the decision-making process.
Conduct a patch test
Before applying essential oils, perform a patch test by applying a small amount of diluted oil to a less sensitive area, such as the forearm, to check for allergic reactions or irritation. Wait 24 hours to observe any adverse effects.
Begin gradually
Introduce aromatherapy in small doses. Start with mild, familiar scents and short sessions to gauge the individual’s response. For instance, diffuse lavender for 10–15 minutes in their room or apply a small amount during a hand massage.
Incorporate personalisation
Tailor the aromatherapy experience to the individual’s needs and preferences. For example, use lavender for relaxation if they have trouble sleeping or peppermint for headaches.
Monitor responses
Regularly assess the individual’s physical and emotional reactions to the therapy. Look for improvements in mood, sleep, or physical discomfort, and adjust the oils or methods accordingly.
Integrate into routine
Gradually incorporate aromatherapy into daily or weekly routines, such as during bedtime, relaxation sessions, or massages. Consistency can enhance its effectiveness and make it a welcomed ritual.

Health risks and prevention strategies of aromatherapy

While aromatherapy offers numerous benefits, it is essential to recognise and mitigate potential health risks, especially for elderly individuals who may have unique vulnerabilities due to their age and health conditions. Below are some examples of the most common risks and strategies to prevent them.

Conclusion

Aromatherapy is a valuable complementary therapy for elderly individuals, offering numerous benefits such as relaxation, improved sleep, and relief from physical discomforts. Its non-invasive nature and holistic approach make it particularly suitable for addressing the multifaceted challenges associated with ageing. However, careful attention to safety considerations, individual health conditions, and preferences is essential to avoid potential risks.

When integrated thoughtfully into eldercare routines and used under appropriate guidance, aromatherapy can significantly enhance the quality of life for older adults, making it a worthwhile addition to their care regimen.
