From July 2010 through June 2011, the number of U. S. service members treated for cold injuries (n=557) was similar to recent prior years. ⋯ Cold injury rates were generally highest among service members who were less than 20 years old and of black, non-Hispanic race/ethnicity. Service members who train in wet and freezing conditions -- and their supervisors at all levels -- should know the signs of cold injury, ensure adequate hydration, and avoid tobacco, caffeine, and vasoconstrictive medications.
