小心进入恋爱关系，一旦进去就不那么容易了: 当人们坠入爱河时，大脑会发生变化。

AI Overview

The brain changes when people fall in love: 

• Brain regions activated
• The limbic system and reward centers are activated, which can lead to a positive mood and strong memories. 
• 
  
• Chemicals released
• The brain releases chemicals like dopamine, oxytocin, and adrenaline: 
• 
  
• 
  
• Dopamine: A "feel-good" hormone that activates the reward circuit and can lead to obsessive thoughts and behaviors 
• 
  
• Oxytocin: A "cuddle hormone" that helps form deep connections 
• 
  
• Adrenaline: Induces a euphoric sense of purpose 
• 
  
• Brain regions deactivated
• The frontal cortex is less active, which can reduce negative emotions and judgments. This can lead to "rose-colored glasses" and an inability to critically assess a new lover''/s flaws. 
• 
  
• Stress hormone levels
• Cortisol levels increase, which can lead to feelings of stress and insecurity. 
• 
  
• Serotonin levels
• Serotonin levels decrease, which can lead to obsessive thoughts and behaviors. 
• 
  
• Hormones released over time
• The hormones released in the brain can lead to positive behavioral and emotional changes, such as increased empathy, generosity, and resilience. 
• 
  
• Brain activation areas expand
• Once the initial excitement wears off, the brain activation areas expand.
