Everyone wants to have a healthy heart. Still, heart diseases affect more than 1 in 3 adults in the United States. The good news is that some simple, everyday habits can make a big difference in your ability to live a healthy lifestyle. Here are some worst habits for your heart, and how to avoid them.

Watching TV

    Sitting for hours on end increases your risk of heart attack and stroke(中风),“some exercise doesn’t make up for the time you sit,”says Harmony R. Reynolds, Why? The lack of movement may affect blood levels of fats and sugars. Dr. Reynolds advises walking around regularly and, if you’re at work, standing up to talk on the phone.

Leaving hostility and depression unchecked

    Are you feeling stressed or sad? It can do harm to your heart. While everyone feels this way some of the time, how you handle these emotions can affect your heart health.“Those with stress are in greater danger; research has shown a benefit to laughter and social support,” Dr. Reynolds says. “And it’s helpful to be able to go to someone and talk about your problems.”

Cutting off from the world

    It's no secret that on some days, other human beings can seem annoying and too difficult to get along with.

    However, it makes sense to strengthen your connections to the ones you actually like. People with stronger connections to family, friends, and society in general tend to live longer, healthier lives.

    Everyone needs alone time, but you should still reach out to others and keep in touch whenever you can.
