A Stanford study found that Caucasians who avoid sun exposure have lower blood levels of vitamin D, with a 40% prevalence among all participants increasing to 53% and 56% among those wearing long sleeves and staying in the shade. The use of sunscreen did not significantly affect vitamin D levels due to insufficient application.
The American College of Physicians recommends that doctors assess the risk of venous thromboembolism and bleeding in patients hospitalized for medical illnesses, such as stroke, before initiating therapy to prevent VTE. Heparin or related blood thinners are prescribed unless the assessed risk of bleeding outweighs likely benefits.
Researchers discovered reindeer use three tactics: panting with nose closed, mouth open and brain cooling system, to prevent overheating while exercising. The team found that reindeer selectively cool their brains only when temperature becomes dangerously high.
