This is Passport to Texas

Winter weather never kept a Texan from enjoying the great outdoors. Even so – everyone needs to exercise caution in the cold to prevent hypothermia.

Dorian Drigalla (Dre-gal-a) is an assistant professor of Emergency Medicine at Scott and White Memorial Hospital.

09—Hypothermia is a condition where the body’s temperature drops below normal and certain physiologic changes happen the body because of that.

There are three stages of hypothermia that determine the severity.

41—Stage one, or mild hypothermia, is when the body’s temperature drops from what is considered normal down between 1 and 3 degrees below that. Stage two – becomes a little bit more obvious in that the person starts to realize they are more than just cold and while they are still conscious, they do realize that they are shivering more, the shivering becomes more noticeable and the rest of the body’s movements are less coordinated. It’s at this point that the body starts to appear more pale. Stage three is when the body temperature drops below ninety degrees. At this point, the body’s reflexes start to fail, the shivering intended in the prior two stages to help warm the body starts to fail. Concentration, speaking and thinking become more difficult.

Severe hypothermia can lead to organ failure and death.
