Hi, today I would like to share about the interesting topic, namely "Why Does Our Cognitive Function Seem to Diminish?", the main reason why I choose that topic because many people can't use their logic when they are falling in love, From a neuroscientific perspective, there are several reasons why falling in love makes us appear (and feel) less intelligent:
1. A Flood of Dopamine and the Disengagement of the Prefrontal Cortex
When we fall in love, the brain releases large amounts of dopamine into the reward system. This activates the same areas as substance addiction. The problem is, when this emotional (limbic) system becomes overactive, activity in the prefrontal cortex (the centre for logic, decision-making, and self-control) actually decreases.
Analogy: Your emotional engine is revving at full throttle, whilst your logical brakes have failed.
2. Decreased Serotonin Levels
Research shows that people who are in love have low serotonin levels, similar to those with Obsessive-Compulsive Disorder (OCD). This is why you find yourself constantly thinking about them (intrusive thoughts), making it difficult to concentrate on work or university assignments.
3. Excessive "Cognitive Load"
Our working memory capacity is limited. If 80% of your brain’s energy is spent analysing the meaning behind “Hang on, did they just smile at me?”, then only 20% remains for tackling calculus or a work report. This isn’t a drop in IQ, but a problem of resource allocation
✅How to Overcome the "Foolishness" of Being in Love
Although it’s hard to fight hormones, you can minimise their impact with a few strategic steps:
1. Apply the "10–20 Minute Rule"
Don’t let yourself get lost in daydreams or endless social media stalking. Set aside specific time, for example: allow 10–20 minutes out of every hour when you’re constantly thinking about them, then force your brain back to work or engage in activities that support productive work or hobbies. This helps retrain your prefrontal cortex to regain control.
2. Avoid Making Major Decisions (such as making promises) whilst in love
If possible, postpone crucial life decisions whilst you are close to the person you love, as you are currently at the peak of the infatuation phase. Remember, your assessment of risk is currently distorted; counterbalance this by engaging in activities that make you sweat or keep you busy, with the aim of reducing the infatuation phase
3. Grounding: Return to Reality
Love often leads us to create an idealised narrative about someone. Try to remain objective.
Tip: Write a list of their human traits or minor flaws to remind your brain that they are an ordinary person, not a perfect god or goddess.
4. Intense Physical Activity
Intense exercise can help burn off excess energy and rebalance neurotransmitters in the brain. This is the quickest way to ‘cool down’ an overheated limbic system.
Important Note: This phase is temporary. Over time, stress hormones (cortisol) and dopamine will stabilise, and your cognitive abilities will return to normal as the relationship enters a more stable phase (attachment).
