Studies Show Habitually Lying Causes Health Problems

Two common traits of the self-made millionaires in my Rich Habits Study were: honesty and good health. I wondered if it was a coincidence that 95% of the self-made millionaires in my study had forged the Rich Habit of being truthful and that 95% of the self-made millionaires indicated that they were in good health.

So, I decided to do some more research. What I found opened my eyes about the negative health consequences of lying.

This fascinating article by Lifehacker reveals that lying taxes your brain, causes long-term stress which depresses your immune system and ultimately devastates your health.

Another interesting read that I uncovered on the negative health affects of lying, was a study conducted by Anita Kelly, Professor of Psychology at the University of Notre Dame, Indiana.

Kelly studied 110 adults over a 10 week period to determine if lying had any impact on their health. In the study, half of the participants were asked not to lie throughout the study period while the remaining half were not given any specific instructions. Each participant was required to keep track of how many lies or ‘fibs‘ they told each day. They each took a lie detector test every week and answered a questionnaire regarding their mental and physical health as well as the quality of their relationships.

Both teams lied less during the testing period, but the group that was asked to stop lying showed health improvements. Kelly stated, “We established very clearly that purposefully trying not to lie caused people to tell fewer lies. When they told more lies, their health went down. And when they told the truth, it improved.”

The bigger the lie, the worse it is for your health. The more frequently you lie, the worse it is for your health. If you think that small, innocent lies don’t cause damage, you are wrong. They also discovered that telling three less lies per week resulted in four less mental health issues and physical complaints three fewer times. Here’s the link that references this study.

Neurologists and geneticists around the world are beginning to unlock the keys to how our brains work in preventing and causing diseases that plague mankind. Habitually lying results in long-term stress. When we feel stress, there is a domino effect of physiology that takes place inside our bodies. Stress causes the hypothalamus to increase the release of epinephrine and norepinephrine. These hormones make the heart beat faster and prepare the body for fight or flight. If the stress lingers, a gene on chromosome 10, called CYP17, is activated. This gene goes to work to convert cholesterol to cortisol. Cortisol is used in virtually every part of the body and it’s purpose is to integrate the body and the mind. The body and mind then work in harmony to escape the outside world danger responsible for the stress.

One of cortisol’s side effects, unfortunately, is that it depresses the immune system by reducing the production of lymphocytes – white blood cells. The gene CYP17 also turns on another gene called TCF, which suppresses the the creation of a protein called interleukin 2. Interleukin 2’s purpose is to put white blood cells on high alert. White blood cells are our main defense against viruses, diseases, germs and any parasites that infect the body. Long-term stress, therefore, makes us more susceptible to disease.

Lying is not just bad habit that damages your credibility and your relationships. It turns out habitual lying also impairs your health and shortens your life expectancy, as it increases your susceptibility to disease. If your goal is to be healthy and live a long life, tell the truth and avoid lying. Habitual liars are not just bad people, they’re unhealthy people.

Thomas C. Corley About Thomas C. Corley

Tom Corley understands the difference between being rich and poor: at age nine, his family went from being multi-millionaires to broke in just one night, due to a catastrophic fire that destroyed his Dad's thriving business. For fourteen years they struggled with poverty. There were eleven in Tom's family, and they lived in constant fear of losing their home.

Driven by the desire to unlock the secrets to success and failure, Tom spent five years studying the daily activities of 233 rich people and 128 poor people. He discovered there was an immense difference between the habits of the rich and the poor. During his research he identified over 300 daily activities that separated the “haves” from the “have nots.” Tom decided to write a book to share what he learned. That book, Rich Habits: The Daily Success Habits of Wealthy Individuals (1st Edition), went on to become an Amazon Bestseller in the United States forty times over a three year period. To give you some perspective, in order to be a true Amazon Bestseller in the United States, where you actually receive a specific Bestseller designation from Amazon, you need to be in the top 100 of all books sold by Amazon in the United States in a given day. Rich Habits did that for nearly thirty straight days, rising as high as #7, eclipsing such Bestselling authors such as Stephen Covey, Robert Kiyosaki and J.K. Rowlings. Imagine that - an unknown, first-time, self-published author selling more books than J.K. Rowlings!

Tom now travels the world, sharing his Rich Habits and motivating audiences at industry conferences, corporate events, universities, multi-level marketing group events, and global sales organizations’ presentations and finance conferences. He has even spoken on the same stage with famous entrepreneurs and personal development experts, such as Sir Richard Branson, Robin Sharma, Dr. Daniel Amen, and many others.

Tom has shared his insights on various national and international network, cable, and Internet television programs such as CBS Evening News, NBC News, Yahoo Financially Fit,, India TV, Australia, and a host of others. He has been interviewed on many prestigious nationally syndicated radio shows, including the Dave Ramsey Show, Marketplace Money, and WABC.

Tom has been featured in numerous print magazines—such as Money magazine, Inc. Magazine, SUCCESS Magazine, Entrepreneur magazine, Fast Company magazine, More magazine, Epoca Magazine (Brazil’s largest weekly) and Kiplinger’s Personal Finance magazine—and various online publications, including USA Today, CNN, MSN Money,,, and the Huffington Post. Tom is a frequent contributor to Business Insider,, and a few other media outlets.

National publicity has garnered international media attention for Tom and his Rich Habits research spanning 23 countries. Broadcast media, online publications, and television throughout Asia, the South Pacific, Europe, the United Kingdom, and Central and South America have shared his powerful message.

In an effort to help parents, grandparents, teachers and adults become success mentors to the younger generation, Tom released his second book, Rich Kids: How to Raise Our Children to be Happy and Successful in Life in 2014. This book was the self-help category winner of the 2015 New York Book Festival and Runner-up in the prestigious 2015 Writer’s Digest Self-Published Book Awards Contest. In 2016 Tom released his third book, Change Your Habits, Change Your Life. This book provides the latest science on habit change as well as more of Tom's unique research on the specific habits that helped transform 177 ordinary individuals into self-made millionaires.
