Long-term, consistent meditation mindfulness changes our ability to handle stress in a better, more sustainable way.

• Practicing meditation reduces the inflammatory response in people exposed to psychological stressors.
  
• Mindfulness practices help us to be less reactive to stressors and to recover better from stress when we experience it. 
  

Meditation also makes our compassion more effective.

• Practicing loving-kindness meditation for others increases our willingness to take action to relieve suffering. 
  
• For long-term meditators, activity in the part of our brains that reflects on thoughts, feelings, and experiences quiets down, suggesting less rumination about ourselves and our place in the world.
  

Meditation does seem to be generally effective for your well-being, but it is equal to many other steps you can take to stay healthy, such as exercise or therapy.

Studies have found a positive link between mindfulness and relationship quality in romantic relationships and relationships with kids.

Mindfulness practice seems to activate the part of the brain involved in empathy and emotional regulation.

• Brief loving-kindness meditation may reduce prejudice toward homeless people.
• A brief mindfulness training may decrease unconscious bias against black people and elderly people.
• Mindfulness may reduce the sunk-cost bias.
• Mindfulness may decrease the negativity bias.

There is some good evidence that meditation affects physiological indices of health, but other factors like education or exercise could also have a role to play.

One study found many of the participants experienced fear, anxiety, panic, numbness, or extreme sensitivity to light and sound that they attributed to meditation.

The type of meditation you choose matters if you want to tackle a specific issue.

Studies have been made to compare four different types of meditation and they found that each type has its own unique benefits. 

Research has yet to arrive at a consensus about how long meditation should take.
