Dehydration occurs when you lose more fluids than you take in, and your body doesn't have enough water and other fluids to do its work. Unfortunately, you can’t always trust your thirst to let you know when your body needs water. Many people don't feel thirsty until they're already dehydrated, so pay attention to other signs of dehydration such as less frequent urination, dark-coloured urine, fatigue, dizziness, and confusion.
Dehydration can have serious consequences, including heatstroke, a condition caused by your body overheating. Untreated heatstroke can quickly damage the brain, heart, kidneys, and muscles. Call 911 immediately if you notice symptoms that could indicate a person is suffering from a heatstroke, such as high body temperature, altered mental state or behaviour, nausea and vomiting, flushed skin, rapid breathing, or racing heart rate.
People who should be especially careful in the heat include elderly or obese individuals, and people suffering from a chronic illness such as diabetes, heart, lung or kidney disease.
Some medication can make the skin more sensitive to sunlight or increase the risk of dehydration. Your pharmacist will explain what to do to mitigate these risks.
As restrictions on outdoor sports begin to lift, there are many ways to stay safe while enjoying the sun. Here are some easy ways to stay cool:
During heat waves, if your home is not air-conditioned, you can take a break from the heat by spending a few hours in a public space, such as a library or shopping mall. Make sure to keep on practicing the proper preventive measures, in any case and that the facilities you want to visit are open to visitors.
