Here’s a New Year’s challenge for the mind: Make this the year that you quiet all those negative thoughts swirling around your brain. All humans have a tendency to be a bit more like Eeyore than Tigger, to ruminate more on bad experiences than positive ones. It’s an evolutionary adaptation that helps us avoid danger and react quickly in a crisis. But constant negativity can also get in the way of happiness, add to our stress and worry level and ultimately damage our health. And some people are more prone to negative thinking than others. Thinking styles can be genetic or the result of childhood experiences, said Judith Beck, a psychologist and the president of the Beck Institute for Cognitive Behavior Therapy in Bala Cynwyd, Pa. Children may develop negative thinking habits if they have been teased or bullied, or experienced blatant trauma or abuse. Women, overall, are also more likely to ruminate than men, according to a 2013 study. “We were built to overlearn from negative experiences, but under learn from positive ones,” said Rick Hanson, a psychologist and senior fellow at the Greater Good Science Center at the University of California, Berkeley.
But with practice you can learn to disrupt and tame negative cycles.
The first step to stopping negative thoughts is a surprising one. Don’t try to stop them. If you are obsessing about a lost promotion or the results of the presidential election, whatever you do, don’t tell yourself, “I have to stop thinking about this.” “Worry and obsession get worse when you try to control your thoughts,” Dr. Beck said. Instead, notice that you are in a negative cycle and own it. Tell yourself, “I’m obsessing about my bad review.” Or “I’m obsessing about the election.” By acknowledging your negative cycle and accepting it, you are on your way to taming your negative thoughts. Acceptance is the basic premise of mindfulness meditation, a practice that helps reduce stress and reactivity. You don’t necessarily have to close your eyes and meditate every day to reap the benefits of mindfulness. You can remind yourself to notice your thoughts in a nonjudgmental manner, without trying to change or alter them right away.
