Meditation has been a part of human culture for thousands of years, valued for its spiritual, emotional, and physical benefits. But what does science say about its effects on our bodies? Let’s explore how meditation can influence your brain and overall health.
When you meditate, fascinating changes occur in your brain. Brain scans reveal increased activity in areas linked to reduced anxiety and depression, as well as enhanced pain tolerance. One key player is the default mode network, which becomes active when your mind is at rest. This network is crucial for improving memory, self-awareness, and setting goals.
Want to boost your empathy? Studies comparing Buddhist monks with new meditators show that the monks have a more developed brain region associated with empathy. Meditation also alters brain waves, increasing alpha wave levels. These waves are known to alleviate negative moods, tension, sadness, and anger.
Meditation doesn’t just change brain activity; it also affects brain structure. Research indicates that after eight weeks of meditation practice, there is an increase in gray matter density in areas related to learning, memory, and emotion regulation. Meanwhile, the amygdala, which handles stress and fear, shows a decrease in gray matter.
Meditation benefits extend beyond the brain. It can lower blood pressure and increase heart rate variability, which is essential for efficient oxygen and carbon dioxide transport in the body. This might sound counterintuitive, but it’s actually beneficial for your cardiovascular health.
Feeling under the weather? Meditation might help. In a study where participants were exposed to the flu virus, those who meditated produced more antibodies and had a stronger immune response.
Meditation’s influence reaches down to the cellular level. Chromosomes have protective structures called telomeres, which guard against DNA damage and cell death. Shortened telomeres are linked to diseases like cardiovascular disease, diabetes, Alzheimer’s, and cancer. Remarkably, cancer survivors who engaged in meditation showed increased telomere length. This suggests that reducing stress through meditation can positively affect the enzyme telomerase, which helps maintain telomere length.
While meditation is not a replacement for medical treatment or a healthy lifestyle, it offers a way to enhance your brain’s health, much like exercising strengthens your muscles. Since your brain governs your entire body, taking time to meditate could be a valuable addition to your wellness routine.

For thousands of years, people have practiced meditation for spiritual, emotional, and physical well-being. But from a scientific perspective, how exactly does meditation affect your body? Does it really do anything?
It all starts in the brain. During meditation, brain scans show increased activity in regions correlated with decreased anxiety and depression, along with increased pain tolerance. The default mode network, in particular, is activated when one’s mind is at rest and not focusing on the outside world. This network has been found to improve memory, self-awareness, and goal setting.
Want to be more caring to your friends and family? When scientists compared the brains of Buddhist monks to new meditators, they found that the region of the brain associated with empathy was much more pronounced in the monks. Meditation also literally changes your brain waves, and we can measure these frequencies. Meditators have higher levels of alpha waves, which have been shown to reduce feelings of negative mood, tension, sadness, and anger.
Additionally, meditation physically changes our brain shape and size. Studies found that after eight weeks of a meditation program, gray matter was denser in areas associated with learning, memory processing, and emotion regulation. Conversely, the amygdala, which deals with stress, blood pressure, and fear, showed decreased gray matter.
When we look at the entire body, we see decreased blood pressure and increased variability of heart rate. While this may sound harmful, it actually plays a critical role in properly transporting oxygen and carbon dioxide throughout your body.
Think you’re getting sick? In a study where both meditators and non-meditators were given the flu virus, meditators produced a greater number of antibodies and had increased immune function.
If we go a little deeper, we can even see changes on a cellular level. Your chromosomes have protective protein complexes called telomeres, which help reduce damage to your DNA and lower cell death. A shortened telomere length has been linked to several diseases such as cardiovascular disease, diabetes, Alzheimer’s, and cancer. Amazingly, when cancer survivors completed a meditation program, their bodies showed significant increases in telomere length. It’s believed that psychological intervention, particularly decreasing stress, has a direct effect on the enzyme telomerase, which has been shown to counteract shortening by adding DNA to the shrinking telomeres.
Of course, meditation is not a substitute for medical advice or a healthy lifestyle. We don’t want you to leave this video thinking it will cure cancer. However, much like hitting the gym can grow your muscles and increase your overall health, meditation may be a way of working out your brain with extra health benefits. Since your brain controls everything, why not relax and say “om” every once in a while?
