The science of hydration in high heat
With the heat index looking to surpass 105 degrees each afternoon lasting through Thursday, hydration becomes increasingly more important. The question is, just how much water is the reight amount to remain healthy?
All categories of people are at risk once the heat index surpasses 105 degrees leading to a signifigant rise in dehydration and heat stroke cases.
According to the CDC, water is the best liquid to drink. When outdoors during extreme heat, eight ounces of water should be consumed every 15-20 minutes leading to an hourly consumption rate of about one quart of water.
Too much water can also be dangerous as water intoxication could become possible. People should consume under 48 ounces in an hour to avoid diluting their salt to water ratio.
Most people's daily food diets allows for enough consumption of salt and electrolyte levels, but if you are outdoors and sweating for multiple hours, then sport drinks can be drank in moderation to restore these levels.
