Dwelling On the Negative All The Time Will Actually Change Your Brain
People say you should always see the glass half full. Turns out, they may be rightâat least when it comes to your brain’s health. Pessimism isn’t just a mood killer. It can actually change how your brain works. Our brains are highly motivated by rewards. We’re much more likely to complete an unpleasant or boring task if we believe there will be a positive payoff at the end. Pessimism can take over our brains’ natural motivation toward reward by making us feel that the reward is not worth a bit of discomfort. This could make you avoid things that you used to enjoy, a hallmark of depression and generalized anxiety. Dwelling too much on negative things is also linked with cognitive decline, memory loss, and a higher risk of dementia later in life. In fact, repeated negative thinking in older adults was associated with early signs of Alzheimer’s disease.
