Fatigue is one of those symptoms easily attributed to other conditions. However, it is something that can arise if there is underlying trouble with the heart. This is because if the heart is having difficulty pumping oxygenated blood throughout the body (think yawning all the time), your body’s cells are going to notice, even if you don’t. In extreme cases, this may manifest as a relentless exhaustion, where you have no energy and struggle to stay awake or complete even simple tasks. If you find yourself feeling tired even after a good night’s rest, consider getting your heart checked.
6. Earlobe Wrinkles
While you probably won’t go looking at your ears for the first signs of heart trouble, there may be some merit to checking out your earlobes. A recent study has found a correlation between diagonal earlobe wrinkles and an increased incidence of hypertension and diabetes. The crease in question varies from nearly horizontal to a diagonal and in some cases, rather prominently separates the earlobe from the rest of the ear. It sounds far-fetched, but consider it in conjunction with other, more prominent signs of heart disease, and the fact that a few studies have produced such results.
5. Ring Finger Length
While checking out your ears, also be sure to take a look at your hands. The length of your ring finger compared to your index finger may be another important clue regarding heart disease. According to various studies from the University of Liverpool, those who have ring fingers that are shorter than their index fingers have a greatly increased risk of developing heart disease, especially when they reach 40 years of age. Longer ring fingers have been linked to a greater level of fetal testosterone exposure, which itself has been linked to better heart health among men.Related: 19 Foods to Keep Your Heart Healthy
