Posted on

23. You switch jobs constantly.

Career changes are incredibly stressful⁠—and if your switches involve a change in income, they can be even more so. One 2019 study published in the journal Circulation found that those who experienced extreme income volatility were twice as likely to suffer from cardiovascular issues when compared to those who were financially stable.

24. You consume too much alcohol.

While you may assume that your drinking habit only affects your liver, it can hurt your heart, too. According to the CDC, “drinking too much alcohol can raise blood pressure levels and the risk for heart disease. It also increases levels of triglycerides, a form of cholesterol, which can harden your arteries.” To keep your heart in tip-top shape, the CDC recommends that women consume no more than one glass of alcohol a day and men consume no more than two glasses per day.

25. You eat red meat.

According to a 2017 scientific analysis published in the International Journal of Preventative Medicine, your affinity for red meat (like beef or lamb) could be putting your heart health at risk. In their review, researchers concluded that many studies showed that a high intake of red meat (at least one serving per day) is associated with an elevated risk of heart disease.

26. You’re constantly exposed to loud noise.

If you live in a bustling city full of noise pollution, constant exposure to high-decibel noise can harm your heart. According to a 2018 review published in the Journal of the American College of Cardiologyfrequent exposure to loud noise can result in vascular dysfunction, autonomic imbalance, and metabolic abnormalities—all maladies that can increase a person’s susceptibility to cardiovascular events.

27. You exercise too much.

While getting the proper amount of exercise each week can be a great way to keep your heart healthy, it is possible to overdo it. In fact, one 2012 study published in the journal Mayo Clinic Proceedings found that chronic extreme exercise (especially for those with genetic risk factors) can lead to heart damage and rhythm disorders. So, how much is too much? According to MedlinePlus, you’ll know that you’ve hit your threshold when you begin feeling tired, experiencing extreme mood swings, and have trouble recovering from things like colds and injuries.
