Description
Nine authors study vitamin D and sleep in young Black women in this 2026 pilot trial. Black women face higher rates of both vitamin D deficiency and short, disturbed sleep than other groups, yet the link between the two is rarely tested in this population.
Forty-three women aged eighteen to thirty gave blood samples and wore wrist trackers for fourteen days. Higher vitamin D levels went with better sleep efficiency and steadier sleep onset times, but not with sleep length. Sixteen women with low levels then took vitamin D for eight weeks and repeated the measures. Pilot work like this shapes larger trials on a fixable factor in sleep health.
