Yes, Llion's mane may help to reduce anxiety, which can in turn help with sleep. Anxiety can make it difficult to fall asleep or stay asleep throughout the night, leading to disrupted sleep patterns and daytime fatigue.

Research has shown that compounds in lion's mane can interact with the serotonin and dopamine systems in the brain, which are involved in regulating mood and anxiety levels. By modulating these systems, lion's mane may help to reduce feelings of anxiety and promote a sense of calm.

For example, a study published in the Journal of Ethnopharmacology found that lion's mane extract reduced anxiety and depression-like behaviors in mice. Another study published in the Journal of Agricultural and Food Chemistry found that lion's mane extract reduced anxiety and depression symptoms in rats.

While the evidence for the anxiety-reducing effects of lion's mane in humans is still limited, there have been some promising results. For example, a small study published in Biomedical Research found that taking lion's mane extract for four weeks improved anxiety symptoms in people with generalized anxiety disorder.

Overall, while more research is needed to fully understand the anxiety-reducing effects of lion's mane in humans, the available evidence suggests that it may be a promising natural remedy for anxiety and potentially improve sleep quality. However, as with any supplement, it's important to speak with a healthcare professional before trying lion's mane or any other natural remedy for anxiety or sleep.
