We've heard that meditation can be good for our mind and perhaps we've even felt the calming benefits ourselves, but what's really going on while we sit in silence?
Although the yogis and monks have been practicing meditation for thousands of years, it is only relatively recently that science has begun to study and understand the molecular-level effects of meditation. We are gradually learning how affected molecules are linked to changes in stress responses and mood.
HOW DOES MEDITATION REDUCE STRESS?
Mindfulness meditation is shown to decrease our stress response by switching which nervous system in our body is activated. In modern life, we are often in our sympathetic nervous system, which is our fight or flight response. This can be triggered by significant life events or even everyday situations such as increased workload, screen time, frustration in traffic or financial worries. By meditating and concentrating on our breathing our body naturally shifts into our parasympathetic nervous system, which allows us to rest and relax, telling our body that it is okay to slow down.
HOW DOES MEDITATION IMPROVE COGNITIVE FUNCTION & SELF AWARENESS?
A study on mindful meditation looked at outcomes six to 12 months after meditating around 20 to 30 minutes a day and observed changes in brain structure and function.
Researchers noticed increases in gray matter density in the hippocampus and other frontal regions of the brain as well as increases in anterior insula and cortical thickness. So what does this mean?
Increases in gray matter and the left hippocampus aid learning, cognition, and memory, resulting in better retention of facts and more mindful behaviour. And increases in the anterior insula and in cortical thickness benefit cognitive function, attention and, self-awareness.
HOW DOES MEDITATION MAKE YOU HAPPIER?
Studies show that meditation can significantly affect hormones and neurotransmitters such as cortisol, serotonin, melatonin, and epinephrine. Cortisol is also known as our stress hormone and meditation has proven to lower its levels in our body, making us feel more relaxed and aiding in the transition to our parasympathetic nervous system as mentioned above. Findings also show that regular meditation increases serotonin which is sometimes referred to as our rest and fulfilment hormone. The results of a 2015 study showed that meditation not only increases serotonin levels but also that these levels can remain elevated throughout the day and night, contributing to an overall sense of happiness.
