Vitamin D for healthier hospital stays
Healthy people with no history of mental disorders, but who have low levels of vitamin D, are more likely to become disoriented and confused once admitted to the hospital for other reasons. The condition is called hospital acquired new-onset delirium, or HANOD, which can increase hospital stays and chances of dying within one year of discharge.

In this study, doctors compared vitamin D levels among 4,508 adults admitted to hospitals between 1993 and 2006. The average vitamin D level on admission was 22 nanograms per milliliter of blood (ng/mL). Those with the highest circulating levels of vitamin D— above 30 ng/mL—were least likely to develop delirium. As vitamin D levels declined, chances for developing delirium increased. Doctors are calling for new studies to determine if vitamin D can prevent this condition.
