A study published in Neuroscience & Biobehavioral Reviews in 2014 shows that meditating for 30 minutes every day for 8 weeks already makes a difference in our gray matter. This is because meditation stimulates neuroplasticity, the fact that we can change our brain. As a result, meditation exercises have a positive influence on, for example, our anxiety system, but also how we deal with stress. All in all, I recommend meditating for at least 10 to 20 minutes every day. This way you get used to the process faster and you will feel good about it sooner!
