Aromatherapy
There are different solutions to deal with sleep disorders; however, the most common way among senior citizens is to use sleeping pills and benzodiazepines in particular as the front-line treatment. More than 39% of sleep medicines is used by individuals older than 60 years. Still, the effects of drug intervention are short-term and most of them attenuate rapid eye movement (REM) stage, which is essential for the mind performance and alleviation of tensions. There are reports of development of dependency and tolerance in the long-run usage of some sleep medicines. Adopting supplementary and alternative treatments as a less risky, economic, easy, and with limited side-effects method is growing in nursing care practices in many health care services. Studies have recommended different methods for improving sleep quality in senior citizens such as a variety of supplementary medicines including music-therapy, therapeutic touch, aromatherapy, relaxation, yoga, acupuncture, and herbal medicines.
Aromatherapy is the controlled use of aromatic oils to preserve and improve physical and mental health, which is practiced as a part of nursing services in many countries such as the UK, Germany, Canada, and the US. Although, the exact mechanism of aromatherapy is not known, it is believed that inhaling aroma can shift autonomic balance toward para-sympathetic and induce relaxing effects on the individual. In addition, following absorption of volatile molecules through nasal mucus membrane, chemical signals are sent to the olfactory bulb and limbic system. Depending on the aroma, neural cells discharge different neurotransmitters like encephalin, endorphin, and serotonin that induce relaxation effects.
One of the volatile herbal oil that is widely used for aromatherapy is extracted from lavender. The plant belongs to lamiaceae family and it is a herbaceuous plant, aromatic, and evergreen. Among the effective chemical compounds found in the plant, linalool and linalyl acetate are notable. The former functions as a sedative by affecting receptors of gamma aminobutyric acid in the central nervous system. There is no report of complicacies caused by consuming lavender essence on human subjects.
