Ocean waves, hello waves, heat waves, goodbye waves, waves of humidity, sound waves. Some of these can positively affect our heath by refreshing us, making us happy, nourishing our spirit. However, two of them have the potential to negatively affect our health—especially when they happen simultaneously. When combined, waves of heat and humidity can have a dangerous effect on our heart rate, our hydration status, and our blood pressure.
This is because when it's hot and humid outside, our bodies desperately try to avoid overheating.
Why? Well, we have thousands of proteins in our body called enzymes, which are necessary for carrying out vital tasks like producing energy. However, these ultra-important proteins can easily be broken down by heat. As a result, when our internal temperature gets too high (say about 104 degrees Fahrenheit), the body tries to expel heat as quickly as possible. It does this by telling our heart to pump harder and faster, which gets our blood closer to the surface of our skin so that it can release the heat. The body also releases fluid and electrolytes in the form of perspiration so that the resulting evaporation can cool us off.
Sadly, this process can also have a serious impact upon your heart health. The fluid and electrolytes that are lost when we sweat are needed for muscle contraction, nerve conduction, and the prevention of further fluid loss. When the cells in our body don’t have enough fluid, the brain sends a signal to our pituitary gland to secrete a chemical that constricts our blood vessels, which causes our blood pressure to rise. With our heart pumping harder and faster, our body rapidly losing fluid and electrolytes, and our blood pressure climbing, it’s like a triple whammy of escalating health risks.
So, what can we do to address the heat and our hydration status?
In terms of the heat:
In terms of our hydration status:
Enjoy the ocean waves of summer. Here’s to your health!
