Lately more and more people have started to practice meditation because it is seen as a great way to improve mental well-being. Old teachings have long praised meditation for helping the mind and spirit. Now science is starting to back this up with real proof of how it can improve mental well-being. Let's explore the ways meditation can really improve our mental health by looking at the science behind it.
Meditation mainly affects how the brain is built and how it works especially in parts that deal with stress anxiety and managing emotions. A key study on how meditation affects the brain was done by Tang, Lu, Geng, Stein, Yang, and Posner. It shows that practicing mindfulness meditation can lead to changes in both the function and structure of important brain areas like the amygdala, prefrontal cortex, and hippocampus. These parts of the brain play a key role in managing emotions handling fear and storing memories.
The amygdala is the part of the brain that deals with emotions like fear and stress. People who meditate often have less activity in this area and also have less gray matter. When the amygdala activity goes down it seems to match up with lower stress levels and several studies show that mindfulness meditation can help with this. The results show that meditation might help lower stress responses in the brain.
The prefrontal cortex which helps with things like making decisions focusing and controlling impulses changes when a person practices meditation. Meditating regularly can make the prefrontal cortex thicker which helps with paying attention focusing better and thinking more flexibly. Getting better at these thinking skills is really important for helping with issues related to mental health problems such as ADHD and anxiety.
The hippocampus is an important part of the brain that helps with memory and learning and it gets better with meditation because it becomes thicker and larger. Research shows that people who meditate often have less thinning of the hippocampus as they age which helps protect their thinking skills. People dealing with depression often experience a decrease in hippocampal size and these changes can really help them.
Also meditation seems to affect brain networks especially the default mode network which is related to thoughts about ourselves and daydreaming that are often connected to feelings of depression and anxiety. Meditation reduces activity in the default mode network and improves how different brain networks connect. This helps people manage their self-critical and anxious thoughts more effectively.
Meditation changes how certain chemicals in the brain work which helps improve mental health. Gamma-aminobutyric acid or GABA along with serotonin and dopamine are chemicals in the brain that help control mood. Regular meditation affects these chemicals which can help keep your mood steady and make you feel more relaxed. This change in brain chemicals shows how meditation can help reduce feelings of anxiety and depression and improve a person's overall mood.
Also meditation is connected to lower amounts of cortisol which is the hormone related to stress. When cortisol levels go down it can lead to less inflammation which is often linked to different health problems and can also help boost your mood. Meditation helps the body relax by boosting the part of the nervous system that calms us down. This makes it easier to deal with stress instead of just reacting in a panic.
To sum it up meditation does more for mental health than just help you relax. It includes a mix of changes in the brain's structure how chemicals in the brain work and shifts in the body that together help boost mental health. Science is now showing that things people have done for ages like meditation can really help alongside regular mental health treatments.
