Ashwagandha may help reduce stress and anxiety by counteracting the sympathetic nervous system and decreasing the release of stress hormones. Some studies have found that ashwagandha can also help improve mood and cognitive function, including attention and working memory. 

Ashwagandha may help improve sleep quality and reset the circadian rhythm, which can help the body rejuvenate over time. 

Ashwagandha contains withanolides, which may have anti-inflammatory and antioxidant effects. 

Some say ashwagandha may also help with joint pain, physical performance, sperm health, memory, immune function, and cancer risk.
