It is not only winters when one is at risk of experiencing a heart-related condition, but the rising temperatures during summer can also put a strain on your cardiovascular activity. For people with heart problems, foggy, hot, humid days can be “downright dangerous,” according to Harvard Health.
The human body should not be too hot or too cold as both conditions can affect the heart. Harvard Health reports that when the human body temperature gets too high, the proteins that build the body and run all of its chemical processes can stop working. The human body sheds excess heat in two ways—radiation and evaporation. Both these processes stress the heart.
In radiation, the human heart redirects blood flow so more of it goes into the skin. This causes the heart to beat faster and pump harder. During a relatively hot day, a human heart can circulate two to four times as much blood per minute as it does on a cold day, reports Harvard Health.
During evaporation, aka perspiration, the human body draws more than just heat from the body. The human body uses evaporation to keep the body cool during the summer. However, it also flushes out sodium, potassium and other minerals needed for muscle contraction, nerve transmission and water balance. To make up for the loss of these minerals, the body begins to make hormones that help it hold onto water and keep mineral loss to a minimum.
You can adopt some easy tricks to avoid stress on your heart during the summer.
Look for cold air: Stay indoors in the cool air from your cooler or air conditioner to avoid heatwaves. Harvard Health recommends taking a cold shower or placing a cool, wet cloth or ice pack under your arm or groin to beat the heat.
Eat Light: During hot days, it is recommended that you eat food that does not further strain your heart. Avoid eating fried things and consume cold salads and fruits. Drink more fluids like juices and water during this time of year.
Avoid the Gym: If the heat is already leaving you sweating, it is recommended that you do not put too much strain on your heart by going to the gym and doing some strenuous exercise.
Drink water but not caffeinated drinks: The water will keep you cool in the scorching sun and will give much needed relief to your heart. Harvard Health recommends drinking a glass of water every hour on dangerously hot and humid days. However, this does not mean that you should also drink sugary soda as it slows the flow of water from the digestive tract into the bloodstream. Also, don’t rely on caffeinated drinks or alcohol for fluids as they can cause or exacerbate dehydration.
