Spaniards have always known about the benefits of an afternoon nap, but now American scientists have proved that regular siestas can have multiple health benefits.
A new study has revealed what Spaniards have known for centuries: that taking an afternoon siesta has considerable health benefits.
A short nap can help to alleviate stress and strengthen the immune system according to new research published in the Journal of Clinical Endocrinology and Metabolism, from the American Society of Endocrinology.
The study was carried out on men who had slept only two hours the previous night and found that having a siesta helped to counteract the harmful effects of lack of sleep, helping the immune system to recover.
“Our data suggests that a 30 minute siesta could revert the hormonal impact of a night of bad sleep,” said one of the study’s authors, Brice Faraut, a scientist at Paris Descartes University in Paris, France.
 The research found that snoozing could restore immune and neuroendocrine biomarkers to normal health.
