The COVID-19 pandemic and social isolation order induced stress/anxiety as well as cellphone dependence. As a result, sleep disruption and mental distress became major health concerns. Gamma-aminobutyric acid type-A receptor (GABAAR) is one of the key players in modulating sleep. Dihydromyricetin (DHM), an herbal compound, plays a role in GABAAR modulation and mitigating anxiety. The investigators' partner in China obtained 288 participants who completed the online survey to gain insight into how stress/anxiety and time spent on cellphones affected sleep and mood. The participants were then enrolled in a randomized placebo-controlled double-blind study to assess the effects of DHM on sleep and improvement on stress/anxiety and cellphone using time.
