Association of sugar-sweetened beverage consumption and sleep quality with anxiety symptoms: a cross-sectional study of Tibetan college students at high altitude.

A study confirmed a moderately significant effect of improved sleep on comprehensive mental health ( g + = −0.53), as well as significant improvements in depression ( g + = −0.63), anxiety ( g + = −0.51), and rumination ( g + = −0.49), and found that there was a dose–response relationship between sleep and mental health, whereby improvements in sleep quality lead to Improvement in mental health ( Scott et al., 2021 ).
