Effectiveness of auricular laser acupuncture on anxiety, stress, sleep quality, fatigue and muscle tension of Psychosocial Care Center professionals: a quasi-experimental pilot study.

Feeling burned out, anxious, or struggling to sleep? A small but promising study published in the Revista Brasileira de Enfermagem explored whether a gentle, needle-free form of ear acupuncture could help healthcare workers feel better — and the results are encouraging.

Researchers worked with 24 professionals from Psychosocial Care Centers, a type of mental health facility where staff are regularly exposed to high levels of emotional and psychological stress. Participants received five sessions of auricular laser acupuncture — a technique that uses low-level laser light on specific points of the outer ear instead of traditional needles. Before, after, and 15 days following their final session, participants were assessed for anxiety, stress, sleep quality, fatigue, and muscle tension in the trapezius (the large muscle running across the upper back and shoulders).

The findings were largely positive. After treatment, participants reported meaningful reductions in anxiety, stress, and fatigue, and they fell asleep more easily at night — a measure called sleep latency. These improvements held up at the 15-day follow-up check, suggesting the benefits lasted beyond the treatment period. Muscle tension in the trapezius was the one area that did not show a statistically significant change. Importantly, participants reported being satisfied with their treatment, and no significant side effects were recorded.

While this was a small pilot study without a control group — meaning larger, more rigorous research is still needed — the results suggest that auricular laser acupuncture may be a safe, comfortable, and effective option for people dealing with stress, anxiety, fatigue, and sleep difficulties, particularly those in high-pressure work environments.

If you are curious about auricular acupuncture or laser acupuncture, speak with a licensed acupuncturist who can assess whether this approach is appropriate for your individual health needs.

This quasi-experimental pilot study (n=24) evaluated five sessions of auricular laser acupuncture in Psychosocial Care Center professionals, measuring outcomes at baseline, post-treatment, and 15-day follow-up using the paired Wilcoxon test. Statistically significant improvements were observed in anxiety, perceived stress, fatigue, and sleep latency. Trapezius muscle tension threshold showed no significant change. Patient satisfaction was high and adverse reactions were minimal and non-significant. As a non-invasive, needle-free auricular intervention, laser acupuncture demonstrated a favorable safety profile and good tolerability in an occupational health context. Limitations include the absence of a control group and small sample size, constraining generalizability. Clinically, these findings support auricular laser acupuncture as a viable adjunct intervention for stress-related symptom clusters in healthcare workers, warranting further investigation through randomized controlled trials with larger cohorts and standardized laser dosimetry parameters.
