A recent study placed sleepers in rooms scented with lavender and then switched to no aroma the next night. The sleepers reported that the quality of their sleep was 20% better when they slept in the lavender-scented rooms. Yet another study discovered that lavender was effective in helping dementia patients to deal with anxiety and disturbed sleep patterns.
The lavender apparently also allows your heart rate and blood pressure to slow so that you can easily enter the parasympathetic state that is most conducive to deep sleep.
This feature will keep your bed and sheets feeling fresh and clean and unlike memory foam you will only have pleasant scents instead of chemical odors.
