Summer may be coming to a close, but, unfortunately, it seems as if the heat won’t be going anywhere just yet. While we’ve certainly enjoyed all of the beach days, barbecues, and camping trips that the weather over the last few months has allowed for, we also can’t deny that scorching hot days have a tendency to leave us feeling seriously drained. Well, it turns out there’s a reason that the heat makes us tired, and, fortunately, there are a few simple ways to deal with it. Read on for a few of our best tips. 

Why the Heat Makes Us Tired

When the thermometer climbs, our bodies have to work overtime to keep our internal temperature regulated. The main way that this is achieved is through sweating, which carries heat away from the center of the body through our skin. However, this process consumes a significant amount of energy and causes us to lose fluids, decreasing blood volume and making it more difficult for the heart to circulate blood and oxygen. All of these factors combined are a recipe for fatigue.

How to Beat the Heat

Stay Hydrated: Make sure to drink plenty of water throughout the day to replenish lost fluids and give your body the support it needs to regulate your temperature more efficiently. The best way to do this is to drink small amounts of water at frequent intervals—aim for about 24-32 oz. per hour.

Be Strategic: Try to plan your schedule so that you’re able to avoid performing any strenuous activities during the hottest parts of the day. Save outdoor tasks for mornings or evenings when the temperature tends to be lower and the sun is less intense.

Keep Cool: Use fans, air conditioning, and cool showers to lower your body temperature throughout the day. Stay in the shade when working outdoors, and if you start to feel ill, seek medical attention as quickly as possible.
