Good sleep is essential for overall health. Unfortunately, many people suffer from insomnia, or chronic inability to fall asleep, stay awake, or achieve a quality sleep. Herbal teas are popular choices when it comes to calming and improving sleep. For centuries, teas have been used all over the world as natural sleep aids. Modern research also supports the ability of herbal teas to improve sleep.

Chamomile Tea : Chamomile tea contains an antioxidant called apigenin, which can help start sleep. However, the evidence to support the benefits of chamomile is inconsistent. But if it works for you, consume it.
Valerian Root: It is an herb used for centuries to treat problems like insomnia, nervousness and headaches. Valerian can induce drowsiness by increasing levels of a neurotransmitter called GABA. Smaller studies suggest that valerian root may improve overall sleep quality by shortening the time it takes to sleep and reducing nighttime awakenings.
Lemon balm: Lemon balm is an aromatic herb that increases GABA levels, at least in the brains of mice. Drinking tea with lemon balm can reduce insomnia.
Passion fruit: Drinking passion fruit tea can improve the overall quality of sleep. Also the fruit of passion, in combination with valerian roots can reduce insomnia.
Magnolia bark: In studies in mice, magnolia bark tea has been shown to reduce the time it takes to sleep and increase the amount of overall sleep by modifying GABA receptors in the brain. However, further studies are required to confirm these effects in humans.
