Stress is a multifaceted physiological and psychological response that occurs when individuals perceive an imbalance between external demands and their ability to cope. This response primarily activates the hypothalamic pituitary adrenal (HPA) axis and the sympathetic nervous system, resulting in hormonal and autonomic changes that influence both physical and mental health. Although acute stress can be adaptive, prolonged or chronic stress is detrimental and has been linked to cardiovascular diseases, immune dysfunction, anxiety, depression, and sleep disturbances. Occupational stress is particularly prevalent among working professionals worldwide, with recent meta-analytic evidence suggesting that nearly 30–40 percentage of working adults experience moderate to high levels of stress, especially in urban and highly competitive work environments. Factors such as extended working hours, excessive workload, role conflict, job insecurity, and poor work–life balance significantly contribute to occupational stress. Persistent exposure to such stress negatively impacts productivity, increases absenteeism, and reduces overall quality of life. The adverse physiological effects of stress are largely mediated through sustained activation of the HPA axis and dysregulation of the autonomic nervous system, leading to elevated cortisol levels, reduced heart rate variability, fatigue, and impaired emotional regulation. Considering the limitations and potential side effects associated with long-term pharmacological management, increasing attention is being directed toward non-pharmacological and complementary approaches for stress reduction. Naturopathy is a holistic system of healthcare that emphasizes the body’s innate capacity for self-healing, guided by the principle of Vis Medicatrix Naturae, or the healing power of nature. Naturopathic interventions—including mud therapy, hydrotherapy, massage, and other natural modalities aim to restore physiological balance in accordance with the Panchamahabhuta theory. Massage therapy, which involves the systematic manipulation of soft tissues, exerts beneficial effects on the musculoskeletal, vascular, and nervous systems. Aromatherapy is a complementary modality that employs essential oils derived from plant sources to enhance physical and psychological well-being. Aromatherapy massage integrates massage techniques with essential oils diluted in carrier oils to augment therapeutic effects. Head massage, in particular, is a well-established intervention for stress management, as it stimulates pressure points on the scalp and neck, enhances local circulation, and promotes muscular relaxation. When combined with aromatherapy oils such as clary sage, head massage may further activate the parasympathetic nervous system, regulate heart rate, and facilitate the release of neurotransmitters including endorphins and serotonin. Clary sage (Salvia sclarea) essential oil, extracted through steam distillation of the flowering tops and leaves, has traditionally been recognized for its calming, antispasmodic, and antidepressant properties. Its major bioactive constituents, linalyl acetate and linalool, are known to influence gamma-aminobutyric acid (GABA) receptor pathways, thereby promoting relaxation and emotional stability. Emerging evidence suggests that clary sage oil may reduce cortisol levels, alleviate anxiety, and induce a sense of calm when administered via inhalation or topical application in conjunction with massage. The integration of clary sage essential oil with head massage may therefore exert a synergistic effect by combining the mechanical relaxation of massage with the neurochemical and olfactory benefits of aromatherapy. This intervention is particularly suitable for working professionals, as it is simple, non-invasive, and cost-effective. However, despite its potential benefits, there is a scarcity of controlled clinical trials evaluating the effectiveness of clary sage oil based head massage for reducing occupational stress. Hence, the present study aims to assess the effectiveness of head massage using clary sage essential oil in reducing stress among working professionals through a randomized controlled trial design.
