Sleepytime tea: a blend of flowers, herbs and spices all supposedly designed to make you ready for bed.
But does it actually work or is it all placebo?
According to a 2011 study, chamomile had small to moderate effects on sleep when compared to placebo, but these results were not significant nor convincing.
A meta-analysis concluded valerian likely to help in mild to moderate cases of insomnia.
A double-blind, placebo-controlled study found passionflower (Passiflora incarnata) to be effective at significantly improving sleep quality when compared to placebo.
Perhaps it’s not the tea at all that improves sleep quality. Reading, praying, stretching and mediating may all have the same relaxing effects of sipping on a warm tea before bedtime.
In conclusion, the evidence is by no means strong, so find whatever converts your stressful day into dreamland and stick to it.
Here are some sleepytime teas and their primary ingredients:
- Classic Sleepytime by Celestial Seasonings: Chamomile
- Sweet Dreams by Bigelow: Chamomile
- Nighty Night by Traditional Medicinals: Chamomile and Passionflower
- Bedtime by Yogi: Chamomile, Valerian and Passionflower (most promising)
