A Randomized Controlled Clinical Trial Using Portable EEG Devices to Evaluate the Effect of Essential Oil Ointments on Improving Insomnia in Healthcare Workers

INTERVENTION: Intervention group:Received standard sleep hygiene education and selected standardized plant essential oil balm. Through the bedroom diffuser method, start using it 30 minutes before going to bed, once a day, for continuous intervention for 8 weeks.;Control group:Receive standard sleep hygiene education, use ordinary balm with the same scent and packaging, and start using it 30 minutes before going to bed through bedroom diffusion. Do it once a day for 8 consecutive weeks.; CONDITION: Insomnia PRIMARY OUTCOME: Sleep latency;(Percentage of (S3 + S4) / Proportion of deep sleep);Actual sleep time; SECONDARY OUTCOME: Insomnia Severity Inde X(ISI);Pittsburgh Sleep Quality Inde X(PSQI); INCLUSION CRITERIA: 1. According to the 3rd edition of the Chinese Diagnostic Classification of Mental Disorders, insomnia was diagnosed; 2. Age range: 18 to 60 years old; 3.
