Two Primary Ways that Negative Thinking Affects Your Health

There are 2 primary effects that negative thinking has on your life:

It has a negative impact on your mood and outlook on life.

Negative thinking feels bad. Thinking negative thoughts can make you feel sad, afraid, angry, hopeless, and negative in general. These emotions taint the way you view the world and have a deleterious effect on your ability to make wise decisions.

Negative thinking inhibits your ability to achieve goals.

For any objective, you have things pulling you toward your goal and other things pushing you away. When you think negative thoughts about achieving a goal, you’re much less able to accomplish it.

  • Imagine you’d like to explore new work opportunities. A certain job has opened and it always has been a goal of yours. But then you start thinking about it:
  • “There are so many new responsibilities, how would I manage?”
  • “Am I really prepared for that position?”
  • “My job is so easy now, why make my life harder?”

    “My co-worker is much more educated than me – how would I measure up?”

    “My significant other would have to help more around the house, I don’t want to put any burdens on anyone else.”
  • All of a sudden, that dream job doesn’t sound so dreamy anymore. Negative thinking makes goals seem harder than they are in reality.

These two negative effects are pervasive. They influence your entire life. But, there are additional consequences as well.

How to Limit Your Negative Thinking Patterns

Luckily, there are ways to limit your negative thoughts and bring in positivity each day:

Check yourself throughout the day for negative thoughts. Use a timer and perform a check every 15 minutes. Check yourself during your regular daily activities:

  • Lying in bed
  • Shower
  • Driving to work
  • Work
  • Lunch
  • And so on
  • When you notice a negative thought, change it to one that’s more positive. For example, you can change the thought, “I hate driving to work” to “Driving sure beats taking the bus. I can listen to my music as loudly as I like.”
  • Get into the habit of thinking positive thoughts. Before doing any task, take 15 seconds and think a few positive thoughts about it. The task will be easier and more enjoyable.
  • Spend more time with positive people. It’s unlikely that you’ll rise far above the people you spend the most time with. Ensure that the people around you are positive.

Reducing the incidences of negative thinking is one of the most effective ways to spend your time and enhance your life. Negative thoughts can harm your happiness, success, and health. Spend time to ensure that your thoughts are supportive and positive and turn your life around.

Create a positive space. Hang up motivational and positive thoughts on your wall, refrigerator, mirror, and office space. Anywhere that you can look to for positive support through out the day.
