Negative thought, lack of expression, social isolation, anxiety, stress etc do increase the chances of developing various sorts of cardiovascular disease, and can make existing condition worse. Be happy and one reason for doing so is for your heart. Happiness or an upbeat approach to life protects the blood vessels and keeps your heart healthy. Some studies have demonstrated that positive thoughts or an outlook confer some protection against heart diseases.

One could feel energetic, having a sense of well-being, or being on an even emotional keel and guard the heart. By counteracting stress, emotional vitality could calm the stress-induced arousal of the nervous system that boosts heart rate, elevates blood pressure, and activates inflammation and other heart disease-promoting processes. Positive emotions might contribute to an individual’s sense of control over his or her destiny, which has been associated with protection against heart disease. It might make it easier to make or use social connections. Then again, it could be that people with high emotional vitality are less likely to develop heart disease because they have healthier behaviors, like smoking less, exercising more, or controlling their weight.

Your genes, early learning, and family and social environments set the stage for whether your outlook on life is essentially positive or negative. If yours is a bit on the negative side, don’t despair and loose hope. Get help of psychiatrists, psychologists, and other mental health counselors or others and get on working to improve it. This goes beyond the power of positive thinking.  It involves several different approaches. For instance, deliberately focus on events (e.g. a holiday) or activities (a cool swim on a hot Saturday afternoon) that give you pleasure and take a mental snapshot to recall later. Make a journal where you can jot down the things that you enjoyed doing, so you can relive those events/activities every time you read it. Or simply share the experiences with others. Engage in activities that call on your inherent strengths, either at work, home, or play.

Feel energetic and chances are you will actually have the energy. Resolve issues with others if any as unresolved issues leads to mental stress and leaves you dissatisfied. Has your daily life been full of things that are interesting to you? Make a list and try to do at least some of them once in a while and do review the list. Note and study your behavior like have you been in firm control of behavior, thoughts, emotions, feelings? Counsel yourself. Question yourself and soon answers will start coming to you. Ask yourself when something made you disturbed that why it happened?

The power of positive thinking is immense, and once you are free from the fixed perception which makes you trap in the wrong or right and, you will experience the moment without judging it and that would definitely make you happy. You have to be happy for yourself and for your heart. Apply your strengths to something outside yourself that helps you create meaning in your life. You have got to accentuate the positive, eliminate the negative, latch on to the affirmative.
