Inducing a 6-hour phase advance in the elderly: effects on sleep and temperature rhythms.

abstract：:Restless legs syndrome has been associated with serum iron deficiency in clinical studies. However, studies investigating this relationship have had inconsistent results and there are no studies in young adults. Therefore, we investigated the relationship between serum measures of iron stores and restless legs syndrom...
