Emotions Can Change Your DNA

Cheer up and think positive thoughts: We all give words of advice like these at some time to a friend, relative, or colleague who is ill, worried or otherwise out of sorts. Can't hurt. Right?

Actually, scientific evidence in the last half century clearly shows that your emotions - the good ones and the bad - affect you in multiple ways: health, schoolwork, job performance, relationships and much more.

Whether you feel them naturally or intentionally - "today I will think only good thoughts" - your emotions are kind of like the old adage, "you are what you eat."

It was not until the 19th century that substantial written empirical analyses of emotions began to emerge, when noteworthy figures such as Darwin and Freud took more scientific approaches.

After being within the domain of philosophers for thousands of years, emotions are now closely scrutinized in 21st century research laboratories, where scientists can actually observe their effects on human DNA.

'Intention' Shown to Be Potent Force

Cell biologist Glen Rein ... and IHM Research Director Rollin McCraty conducted a series of experiments in the early 1990s involving DNA and intentionally generated emotions. A decade later interest in these experiments persisted. After numerous requests, McCraty summarized their data and published the results of the research in 2003 in a brief report titled Modulation of DNA Conformation by Heart-Focused Intention.

"The results provide experimental evidence to support the hypothesis that aspects of the DNA molecule can be altered through intentionality," Rein and McCraty wrote. "To our knowledge, this study was the first to correlate specific electrophysiological modes with the ability to cause changes in a biological target (DNA) external from the body. The data indicate that when individuals are in a heart-focused, loving state and in a more coherent mode of physiological functioning, they have a greater ability to alter the conformation (shape or structure) of DNA."

Participants in the experiments ... included a test group of individuals trained and experienced in HeartMath's coherence-building techniques and a control group who were not. Each test group participant held a DNA sample in a test tube and was directed to use three different methods - one at a time in separate trials - to make a sample wind or unwind. Each control group participant only focused on achieving the same result using one method.

Heart Coherence

It is important to note that the purpose of training test group participants in HeartMath techniques was so they could generate high states of coherence, which the researchers believed would be key to proving their hypothesis: Heart-focused intention can change the conformation of a closely controlled DNA sample in a test tube. Coherence is a state marked by more ordered, or coherent interactions between the body's various systems, including more ordered heart rhythms.

Results

"Individuals capable of generating high ratios of heart coherence ... were able to alter DNA conformation according to their intention," Rein and McCraty found. Generally, participants with the highest levels of coherence affected the samples the most.

"Control group participants showed low ratios of heart coherence and were unable to intentionally alter the conformation of DNA. It is important to note that both the intention to cause a change and heart coherence were important variables in the outcomes of the experiments."

"A number of nonlocal studies in which people hold an intention to affect a biological system over longer distances have also revealed dramatic effects," Rein and McCraty wrote. "In these studies the distance between the targets and the people holding the intention are well beyond the range at which conventional electromagnetic fields could conceivably mediate the effect."

They cited one of the nonlocal studies they conducted in which an individual was 0.5 miles away from a DNA sample. "... Results from a series of five nonlocal trials (including the 0.5-mile test) demonstrated a significant change in DNA conformation."

"While the DNA utilized in this experiment was derived from an exogenous (external) source, it is likely that an individual's own DNA would be more 'tuned' or resonant, and therefore even more responsive, to that person's intentions," they said. "Thus, though clearly in need of further testing, it is conceivable that individuals could influence their own DNA through a top-down process such as that described ... potentially producing effects of even greater magnitude than those observed in this study."

The finding that heart coherence was key in achieving the results of these experiments may help lead to a better understanding of the role of positive feelings and attitudes in these critical areas: health and healing; phenomena such as the placebo effect; spontaneous remission in cancer; the health rewards of a strong faith; and the positive effects of prayer.
