Why Do Women Tend to Ruminate More Than Men? A Neuroscience Look into Overthinking

By Rialda-Maria Popa


We’ve all been there… lying awake at night, replaying a conversation or worrying about something out of our control. While everyone overthinks at times, studies show that women tend to ruminate more than men. This isn’t just a stereotype; it’s backed by both neuroscience and psychology. But why does it happen? Is it purely biological, or are we shaped to ruminate more because of the way we’re raised? The answer, like most things in neuroscience, is a mix of both. However, by the end of this article, I hope we’ll have a clearer, deeper understanding of why this phenomenon occurs.


What is Rumination?

Rumination is the tendency to repetitively think about negative experiences or emotions, especially in response to stress. Instead of solving a problem and moving on, the brain stays stuck in a loop: analyzing, re-analyzing, and often feeling worse as a result. According to research, women are significantly more likely to ruminate than men, which helps explain why rates of anxiety and depression are also higher among women. [1]


The Brain Behind the Overthinking

Rumination is linked to specific brain systems. The default mode network (DMN), a group of brain regions including the medial prefrontal cortex, posterior cingulate cortex, and precuneus, becomes active during introspection and self-referential thought. Overactivity in this network has been associated with repetitive thinking and emotional distress. [2]

Another key structure is the amygdala, which processes emotional responses and detects threats. In women, the amygdala tends to respond more intensely to negative stimuli, especially during hormonal fluctuations. [3] This heightened reactivity can trigger stronger and more persistent emotional memories.

Finally, the prefrontal cortex, which regulates attention and emotion, may process stress differently in women, making it harder to shift focus away from negative thoughts. This makes the neural loop of rumination stronger and harder to break.


Hormones, Memory & Mood

Hormonal fluctuations also contribute. Estrogen influences serotonin levels and neural plasticity, factors that affect how we regulate mood. During certain menstrual phases, changes in estrogen and progesterone may increase sensitivity to emotional stimuli, making it easier to fall into cycles of overthinking. [4]

Additionally, women tend to have better memory for emotional events, which, while useful, can also mean more detailed recall of negative experiences, feeding the rumination cycle.


Nature or Nurture?

While brain biology matters, social conditioning also plays a key role. Girls are often raised to be emotionally expressive and self-reflective, while boys are encouraged to suppress emotions. This can lead to internalizing behaviors like overthinking in women and externalizing behaviors in men.


The Upside: Awareness = Power

Understanding the science behind rumination is the first step to managing it. Cognitive-behavioral therapy (CBT) and mindfulness practices help rewire how the brain responds to stress. Interestingly, neuroscience shows that regular meditation reduces DMN activity, decreasing the tendency to ruminate. [5]

While overthinking can be exhausting, it also reflects a capacity for deep thought and emotional insight, especially when channeled productively.


Final Thoughts

Women don’t ruminate more because of weakness. In fact, their brains may simply be more tuned to emotion and reflection—tools that, when used well, are strengths. The challenge is learning when to pause, reframe, and let go.

The next time you catch yourself spiraling into a loop of overthinking, remember: it's not just in your head. It's in your brain, and you have the power to change how you use it.
