In survival, getting sleep is important to keep you sharp and make sure that appropriate judgements are made and actions taken. Learn about sleep hygiene from Joe Alton, MD, plus a new study tells you what states in the U.S. are the most sleep-deprived. Also, Dr. Alton discusses first and second degree burns, the difference between sunscreen and sunblock, and what the SPF rating system means. Also, how to identify and treat these common injuries in disasters or other situations where medical help isn't on the way. Nurse Amy and Dr. Bones also discuss the latest about Zika virus, plus how the Army is so lacking in medical providers that they are offering a rapid path to citizenship for foreign medical graduate volunteers. All this and more on the Survival Medicine Hour with Dr. Bones and Nurse Amy.
