In last week’s column I mentioned the danger of hypothermia as a result of swimming in the cold beach water. While most of us know the basics of what hypothermia is there is specific information that could be helpful, especially when swimming during the colder months.
The Mayo Clinic describes Hypothermia as “a medical emergency that occurs when your body loses heat faster than it can produce heat, causing a dangerously low body temperature”. This “dangerously low” body temperature starts at 95 degrees and is more severe the lower it gets.
Your system doesn’t work well when the body is at lowered temperatures. If untreated, hypothermia can lead to heart and respiratory system failure. Eventually it can cause death. Sounds scary right? Does this mean that every time your kid starts to shiver, he/she is going to have serious problems? Of course not. This may just be just an early warning sign for mild hypothermia.
The first thing your body does when its temperature drops is to shiver. What it’s trying to do is generate heat by causing movement. When swimming, this is the sign that it’s time to warm up. It may be a matter of just sitting in the sand for awhile then jumping back in the water on a warm day. Or when conditions are more serious this is the signal that you need to get out of the water and warm up, now!
Hypothermia is divided into three categories- mild, moderate, and severe.
The symptoms for mild hypothermia include shivering, hunger, nausea, fast breathing, difficulty speaking, slight confusion, lack of coordination, fatigue, and increased heart rate. As your temperature continues to drop and moderate to severe hypothermia kick in. Shivering eventually stops and you’ll start to show clumsiness, slurred speech, confusion (even to the point of trying to remove warm clothing) and eventually loss of consciousness, weak pulse, and slow, shallow breathing. Babies may have bright red, cold skin, low energy and a weak cry.
Warming a person with a more advanced case of hypothermia can be tricky, since you don’t want the cold blood in the extremities to rush to the center of the body. In these cases, you want to call 911 for professional help and to move the person as gently as possible in doors. Remove wet clothing and cover them in lots of blankets. Then wait for help to arrive.
Differentiating between mild and more severe cases can at times be difficult so, as always, when in doubt call 911. But for those cases that we all experience where we’re just shivering a little and our body temperature is near normal warm sun and maybe a hot chocolate is just the thing. Then get back out there and keep having fun!
The good news is that the water is warming up into the 60s, and soon will be comfortable for swimming. Just remember that even in warm water swimming for long periods of time can still drop your body temperature.
