With temperatures this high, there’s only one thing on our minds - water!
As we look forward to warmer temperatures ahead, the change from cooler weather can create health risks for many people. One dangerous aspect of cold water that isn’t often mentioned is cold water shock.
Cold water shock causes the blood vessels in the skin to close, which increases the resistance of blood flow. Your heart rate is also increased, as a result your heart must work much harder, and your blood pressure goes up. Cold water shock can cause heart attacks, even in the relatively young and healthy. It also increases the risk of drowning for experienced swimmers in calm water.
Cold Shock responses fall into three categories:
Threat No. 1 – Loss of breathing control (3-5 minutes or more)
Threat No. 2 – Heart and blood pressure problems
Threat No. 3 – Impaired mental ability
Remember to tread carefully; take your time before splashing into the cold water and wear your life jackets!
