Furthermore, magnolia bark extract has been shown to alleviate anxiety, which often contributes to sleep loss and vice versa.
A study in 40 women ages 20–50 found that taking 250 mg of magnolia and phellodendron bark extract three times a day resulted in greater relief of short-term and temporary anxiety than taking a placebo.
Other tips to improve sleep
According to the National Sleep Foundation (NSF), a handful of studies suggest that exercise significantly improves the sleep of people with chronic insomnia.
“The only study that looked at the effects of a single exercise session found that a bout of moderate-intensity aerobic exercise (e.g., walking) reduced the time it took to fall asleep and increased the length of sleep of people with chronic insomnia compared to a night in which they did not exercise,” says the NSF.
