Cold Water Shock - What Is It and How To Avoid It
Cold water is any water below 15°C. Entering into cold water can have a serious effect on your body, so it is important to be aware of Cold Water Shock.
The average sea temperature is 12°C and rivers are usually colder, so this applies for most of the year in the U.K.
What happens?
- skin blood vessels close, blood flow resistance increases
- the heart has to work harder so blood pressure and heart rate increases
- sudden skin cooling causes involuntary gasps for breath
- movement can be seriously affected
- breathing rates can increase dramatically and get out of control
- you might panic and inhale water into your lungs
What are the dangers?
- it can happen quickly and lead to drowning unless medical care received immediately
- Cold water shock can cause heart attacks even in the young and healthy
