Too Soon to Swim?
The pool may look inviting as outside temps begin to heat up but is it still too cold to swim? Probably. According to the National Center for Cold Water Safety, it’s risky to swim in water that’s below 70 degrees Fahrenheit. For most pools in the Valley, that means we still need the water heat up another 10 degrees. And even then, bear in mind that most public pools are kept between 83 and 86 degrees. Waiting out the cold reduces risk and makes swimming more enjoyable.
What’s the Risk?
Taking in Water
Sudden changes in temperature can have a major impact on your body and increase the risk of drowning. Think about your reaction when you’re unexpectedly scared or surprised – you likely gasp – taking in a deep sharp breath through your mouth. If you’re underwater, you’ll take in water instead of air which can lead to drowning.
Increased Heart Rate and Blood Pressure
Between the shock of the cold water, and your blood vessels contracting to prevent heat loss, your heart rate and blood pressure are likely to increase which is dangerous for anyone but can be even more life threatening for someone with heart problems.
Loss of Movement
Your body will prioritize heating your core to protect your vital organs, reducing blood flow to your arms and legs. This will slow your movement and may impact your ability to keep yourself afloat.
Panic Breathing
Any of the above involuntary responses to the cold water could cause you to panic, leading to increased breathing and even brain fogginess like lack of judgement.
Tips for Swimming Safely in Cold Water
In any temperature water, never swim alone.
If you do choose to brave the cold water, get in gradually to allow your body to slowly acclimate to the water. And wait to put your face underwater until you’re sure you can regulate your breathing.
Avoid deep areas where the water is much colder, and if you can’t touch the bottom, wear a life jacket so you don’t have to rely on your arms and legs to stay afloat.
How Cold is Too Cold?
While experts recommend most people hold off on swimming until the water temperature reaches at least 70 degrees, remember your body can have adverse reactions even in warmer water.
Many factors affect how our bodies react and too cold for one person may be just right for another. Body fat, acclimation, and protective gear can all change the way your body responds to cold.
In any temperature, it’s best to let your body be the judge. Watch for warning signs that your body is struggling like shivering, pain, or feeling like you can’t get enough air. If you have any of these reactions to the water, it’s best to sit on the edge and dip your feet in or stay on the sidelines altogether.
