Does Grounding Affect Heart Health?

Have you ever wondered if simply connecting with the ground beneath your feet could have a profound impact on your heart health? Grounding, also known as earthing, is the practice of allowing yourself to come into direct contact with the ground, whether it’s through walking barefoot or using grounding mats. This article explores the fascinating relationship between grounding and heart health, revealing the potential benefits that this simple and natural practice may have in supporting a healthy cardiovascular system. Let’s explore together the science behind grounding and its potential effects on your heart!


What is grounding?

Grounding, also known as earthing, is a practice that involves connecting with the Earth’s natural electrical energy to balance and harmonize the body. It involves physically touching or being in close proximity to the Earth, which allows the transfer of free electrons from the Earth’s surface into the body. These electrons are believed to neutralize free radicals and reduce inflammation, promoting overall health and vitality.

What is heart health?

Heart health refers to the overall well-being and proper functioning of the heart and the cardiovascular system. A healthy heart is crucial for optimal blood circulation, supplying oxygen and nutrients to all organs and tissues in the body. Good heart health includes factors such as maintaining healthy blood pressure, reducing inflammation, and ensuring proper heart rate variability.

The Link Between Grounding and Heart Health

Effects of grounding on inflammation

Inflammation is a natural response by the body to injury or infection, but chronic inflammation can be harmful and increase the risk of heart disease. Studies have shown that grounding can help reduce inflammation by regulating inflammatory markers in the body. By neutralizing excess free radicals through the transfer of electrons from the Earth, grounding can help decrease the levels of pro-inflammatory cytokines and markers of oxidative stress.

Effects of grounding on blood pressure

High blood pressure, or hypertension, is a major risk factor for cardiovascular disease. Grounding has been found to have positive effects on blood pressure regulation. Research studies have reported that grounding can lead to a significant reduction in blood pressure levels, both systolic and diastolic. The mechanism behind this effect is believed to be related to the ability of grounding to improve blood circulation and reduce inflammation.

Effects of grounding on heart rate variability

Heart rate variability (HRV) is a measure of the variation in the time interval between consecutive heartbeats. It is considered an indicator of autonomic nervous system function, which plays a crucial role in heart health. Grounding has been shown to improve HRV, indicating a positive impact on the balance between the parasympathetic and sympathetic branches of the autonomic nervous system. This improved balance can help reduce stress and promote cardiovascular health.

Grounding Techniques and Practices


Earthing is the practice of directly connecting with the Earth by walking barefoot on natural surfaces such as grass, sand, or soil. This allows the body to absorb the Earth’s electrical energy, including the transfer of free electrons. Spending time outdoors and engaging in activities that involve direct contact with the Earth’s surface, such as gardening or sitting on the ground, can also be considered forms of earthing.

Barefoot walking or running

Walking or running barefoot not only provides the benefits of direct contact with the Earth but also promotes foot and ankle strength and flexibility. It is important to gradually build up barefoot activities to avoid potential injuries and allow the feet to adapt.

Grounding mats and sheets

Grounding mats and sheets are specially designed products that allow individuals to connect with the Earth’s energy while indoors. These mats or sheets are connected to a grounding plug that is then attached to the Earth, typically through a metal rod inserted into the ground. This allows the transfer of electrons from the Earth into the body, simulating the effects of direct contact with the Earth’s surface.

Grounding with water

Water is an excellent conductor of electricity, making activities that involve contact with water a form of grounding. Swimming in natural bodies of water, such as lakes or oceans, can provide the benefits of grounding. Alternatively, using conductive equipment in a bathtub or foot bath, while connected to a grounding source, can also offer grounding effects.

Other grounding techniques

Other grounding techniques include using grounding wristbands or patches that can be placed on specific acupuncture points or areas of discomfort. Additionally, sitting or lying on conductive grounding mats while working or sleeping, or using grounding shoes or sandals, are alternative ways to incorporate grounding into daily life.

Research Studies on Grounding and Heart Health

Study 1: Effects of grounding on cardiovascular risk factors

A study published in the journal Complementary Therapies in Medicine investigated the effects of grounding on cardiovascular risk factors. The study involved participants who either walked barefoot outdoors or used grounding mats indoors for a specific duration. The results showed significant improvements in blood pressure, heart rate, and markers of inflammation in the participants who engaged in grounding compared to the control group.

Study 2: Impact of grounding on hypertension

Another study published in the Journal of Alternative and Complementary Medicine focused on the impact of grounding on hypertension. Participants with hypertension were divided into groups that either utilized grounding mats or received a placebo treatment. The study found that grounding mats led to significant reductions in both systolic and diastolic blood pressure levels compared to the placebo group.

Study 3: Association between grounding and heart rate variability

A study published in the European Journal of Preventive Cardiology explored the association between grounding and heart rate variability. Participants engaged in grounding activities such as walking barefoot on grass or using grounding mats indoors. The findings indicated a significant increase in heart rate variability, highlighting the positive impact of grounding on the autonomic nervous system.

Potential Benefits of Grounding for Heart Health

Reduced inflammation and oxidative stress

One of the key benefits of grounding for heart health is the reduction of inflammation and oxidative stress. By neutralizing free radicals and regulating inflammatory markers, grounding can help lower the risk of chronic inflammation, a major contributor to heart disease.

Improved blood circulation

Grounding has been shown to enhance blood circulation, which is crucial for delivering oxygen and nutrients to the heart and other organs. The improved blood flow can support optimal heart health and reduce the strain on the cardiovascular system.

Enhanced autonomic nervous system function

The balance between the parasympathetic and sympathetic branches of the autonomic nervous system is important for maintaining heart health. Grounding has been found to promote this balance, leading to improved heart rate variability and a decreased risk of cardiovascular problems associated with autonomic dysregulation.

Lowered blood pressure

High blood pressure is a major risk factor for heart disease. Grounding has the potential to lower blood pressure levels, both systolic and diastolic, through its effects on inflammation, blood circulation, and autonomic nervous system function. Regular grounding practices can contribute to maintaining healthy blood pressure and reducing the risk of cardiovascular issues.

Considerations and Precautions

Consultation with a healthcare professional

While grounding is generally safe for most individuals, it is advisable to consult with a healthcare professional, especially if you have underlying medical conditions or are taking medications. They can provide personalized advice and guidance based on your specific health needs.
