Let the sun shine on stroke patients!
Stroke patients often spend long weeks — even months
— convalescing without being exposed to sunlight. In a study
published last year, the authors’ said their previous
investigations had shown low concentrations of Vitamin D in the
blood of 45 stroke patients during long-term hospitalization. The
authors then moved to the next phase, exposing 129 stroke patients
to regular sunlight for 12 months and depriving the same number of
sunlight. Bone mineral density increased by 3.1% for the first
group and decreased by 3.3% (p=0.0001) for the sunlight-deprived
group. Vitamin D serum levels increased fourfold for the first
group. Only one of the first 129 patients suffered a hip fracture,
compared with six in the sunlight-deprived group (p=0.042). The
significant differences indicate that patients recovering from a
stroke would benefit from time spent surrounded by golden sand and
