Scientific research shows that hops, with its natural sedative effects, can increase sleep time. Hops also helps to lower body temperature—falling core body temperature is one important physiological step toward sleep.
Hops appears to work most effectively for sleep when it is used in conjunction with valerian. To reduce stress and lower anxiety Scientific study has demonstrated that both valerian and hops can help alleviate restlessness and anxiety.

Valerian and hops interactions The following medications and other supplements may interact with valerian. Effects may include increasing or decreasing sleepiness and drowsiness, interfering with the effectiveness of the medications or supplements, and interfering with the condition that is being treated by the medication or supplement.
These are lists of commonly used medications and supplements that have scientifically identified interactions with valerian and hops. People who take these or any other medications and supplements should consult with a physician before beginning to use valerian and hops as supplements. Both valerian and hops interact with alcohol. Alcohol can bring about drowsiness. Excessive sleepiness may occur when alcohol is used in combination with valerian or hops.

You may have heard of hops, and very likely tried it if you happen to like beer. Hops is a great part of the beer industry, with the flowers of the female plant being used to make beer due to its aromatic properties.
Similar to passionflower, hops has been well researched, and known to work also by modulating GABA activity. This effect is due to its bitter resins, particularly a component called 2-methylbutenol. In addition, hops can also affect serotonin and melatonin, other key molecules in the sleep cycle regulation, further contributing to its sedative action. If by now you are thinking that beer would do the trick think twice as the alcohol in beer can have a counterproductive effect — see the adverse affects alcohol can have on sleep in our 10 top tips for sleep.
There is always the non-alcoholic version though…in fact, an interesting study with night-shift nurses has shown that moderate consumption of non-alcoholic beer improves sleep quality, due to its hop components. Nevertheless, in order to achieve therapeutic dosages that will promise a good night sleep, my advice will always be to take herbs as a tea, tincture or capsules. Both passionflower and hops are typically well tolerated, safe and adverse effects are very rare.
With any of these herbs be aware of interactions with sedative medications you may be taking as a cumulative effect can occur. More recently, researchers have taken a closer look at hops and their effect on anxiety and sleep disorders. Several scientific studies suggest that hops do have sedative effects. For example, a study reported in the journal PLOS One examined the effects of drinking non-alcoholic beer with hops at dinnertime.
The researchers found that women who drank it showed improvements in their sleep quality. The participants also reported reduced levels of anxiety. Another study published in Acta Physiological Hungarica linked drinking non-alcoholic beer with hops to improved sleep quality among university students.
While hops have shown promise for relieving anxiety and sleep disorders on their own, they might be even more effective when combined with an herb called valerian. This herb has a lot in common with hops. It also has a long history of use as an herbal treatment for insomnia.
According to a review article published in Australian Family Physician , some scientific evidence suggests that valerian can help improve sleep quality, when taken on its own or with hops. However, more research is needed. On top of their sedative properties, hops also have estrogen-like characteristics.
Like soy and flaxseed, they contain phytoestrogens.
