People who struggle with anxiety may purposefully resist relaxation and continue worrying to avoid a large spike in anxiety if something bad does happen, according to a new study by Penn State researchers.
The findings, published in the Journal of Affective Disorders, show that people who were more sensitive to shifts in negative emotion — quickly moving from a relaxed state to one of fear, for example — were more likely to feel anxious while being led through relaxation exercises.
The results could help benefit people who experience “relaxation-induced anxiety,” a condition that occurs when people actually become more anxious during relaxation training.
“People may be staying anxious to prevent a large shift in anxiety, but it’s actually healthier to let yourself experience those shifts,” said Dr. Michelle Newman, a professor of psychology and senior author. “The more you do it, the more you realize you can do it and it’s better to allow yourself to be relaxed at times. Mindfulness training and other interventions can help people let go and live in the moment.”
First author Hanjoo Kim, a graduate student in psychology, said the study also sheds light on why relaxation treatments designed to help people feel better can potentially cause more anxiety.
“People who are more vulnerable to relaxation-induced anxiety are often the ones with anxiety disorders who may need relaxation more than others,” Kim said.
“And of course, these relaxation techniques were meant to help, not make someone more anxious. Our findings will hopefully serve as a cornerstone for providing better care for these populations.”
Newman said that while researchers have known about relaxation-induced anxiety since the 1980s, the specific cause of this phenomenon has been unclear. When Newman developed the contrast avoidance theory in 2011, she thought the two concepts might be linked.
“The theory revolves around the idea that people may make themselves anxious intentionally as a way to avoid the letdown they might get if something bad were to happen,” Newman said.
“This isn’t actually helpful and just makes you more miserable. But, because most of the things we worry about don’t end up happening, what’s reinforced in the brain is, ‘I worried and it didn’t happen so I should continue worrying.'”
The study involved 96 college students: 32 people with generalized anxiety disorder, 34 people with major depressive disorder and 30 controls with neither disorder.
In the lab, the study participants were guided through relaxation exercises before watching videos designed to elicit fear or sadness. The participants then answered a list of questions designed to measure how sensitive they were to changes in their emotional state.
For example, some people may be uncomfortable with the negative emotions incited by the videos right after relaxing, while others might find the relaxation session helpful in dealing with those emotions.
Next, the students participated in another guided relaxation session before filling out a second survey designed to measure their anxiety during the second relaxation session.
The results show that people with generalized anxiety disorder were more likely to be sensitive to sharp spikes in emotion, like going from feeling relaxed to feeling scared or stressed. Additionally, this sensitivity was linked to feeling anxious during sessions intended to induce relaxation.
The researchers found similar results in those with major depressive disorder, although the effect wasn’t as strong.
Kim said he hopes the study can help clinicians provide better care for people with anxiety.
“Measuring relaxation-induced anxiety and implementing exposure techniques targeting the desensitization of negative contrast sensitivity may help patients reduce this anxiety,” Kim said. “Also, it would be important to examine relaxation-induced anxiety in other disorders, such as panic disorder and persistent mild depression.”
