Puressentiel scientific study on sleep - Prof. Damien Léger, study coordinator, physician at the Paris Hospitals, Head of the National Institute for Sleep and Vigilance, Hôtel-Dieu, Paris:
The results from 47 subjects are extremely positive, as they show significant differences across 5 criteria identified as primary or secondary, namely:
Total sleep time (chosen as the primary criterion) increased by an average of 21 minutes 4 weeks after the reference week.
The morning energy score improved by 15.8% by the 4th week.
Morning freshness increased significantly as early as the second week, showing an improvement of 18.1% by the 4th week compared with the reference week.
The night-time quality score improved by 12.5% by the 4th week compared with the reference week.
And the sleep quality score assessed using the Spiegel scale (a validated scale used in reference studies, assessing the following 6 criteria: time taken to fall asleep, sleep quality, sleep duration, night-time awakenings, number of dreams and state on waking) increased significantly as early as the second week and improved by 8.3% from the reference week to the 4th week.
The results of this clinical study conducted on 47 patients who sleep lightly, to assess the efficacy and tolerability of Puressentiel Sommeil-détente, a spray with 12 essential oils, show a continuous increase in sleep duration, alongside improvements in sleep quality and how patients feel on waking, over 3 weeks of product use + one week without use. It therefore has an effect both overnight and on the effects of sleep the following morning.
No rebound effect or withdrawal symptoms were observed when the spray was discontinued, and tolerability and acceptability were excellent.
These results encourage further research to better understand and assess the effect of Puressentiel Sommeil détente-spray with 12 essential oils
