Have you ever walked barefoot on dewy grass and felt an overwhelming sense of calm? This natural desire for connection with the Earth has led to a wellness trend known as earthing—or grounding—which claims to reduce inflammation, relieve pain, and improve sleep.

But while the benefits of earthing have gained popularity, it's essential to explore both sides of the story. Could there be risks hidden beneath the surface? This article uncovers the potential side effects of earthing, offering you a balanced view of this wellness practice.

What is Earthing? Understanding the Practice

Earthing, also called grounding, involves making direct physical contact with the Earth's surface to harness its electrical charge. This can be done by:

• Walking barefoot on natural terrain (grass, soil, sand)

• Using earthing products such as mats, grounding sheets, or electrode patches

Learn more about the science behind grounding in our article on the Science of Grounding: Its Benefits and Techniques.

How It Works

The science behind grounding is based on the concept of electron transfer. Earth's surface carries a negative charge, and when you make direct contact, free electrons flow into your body—neutralizing free radicals and supporting cellular health.

Backed by Science

A study in the Journal of Alternative and Complementary Medicine found that 30 minutes of daily earthing reduced inflammation and improved sleep. Research from the University of California showed improved cardiovascular health and reduced stress in individuals practising regular grounding.

Health Benefits of Earthing

Many people practice earthing for its reported physical and emotional benefits:

Proven Benefits:

• Reduced chronic inflammation

• Better quality sleep

• Stress relief and emotional balance

While these benefits sound promising, let’s explore the other side of the coin.

Potential Side Effects of Earthing You Shouldn’t Ignore

Although earthing is generally considered safe, there are side effects and health risks—especially when practised incorrectly or without proper knowledge.

1. Risk of Electric Shock from Earthing Devices

Using indoor earthing products can pose safety risks if:

• They’re connected to faulty wiring

• Used in wet or humid environments

• Not certified or poorly manufactured

Tip: Only use earthing mats and sheets that are CE-certified or approved by electrical safety authorities. Avoid DIY wiring. You can also learn more about grounding safety in the article 

2. Increased Risk of Infections and Injuries

Barefoot walking outdoors can expose individuals to:

• Sharp objects like glass, thorns, or metal

• Bacterial infections (e.g., tetanus from soil)

• Fungal infections, especially in humid climates

Always check the ground before walking barefoot, and clean your feet after each session to reduce infection risk. For more tips on earthing safely, check out How to Use Grounding Sheets for Optimum Results.

3. Detox Symptoms from Grounding

Some individuals experience earthing detox symptoms during the early stages, including:

• Headaches

• Fatigue or dizziness

• Flu-like aches

• Rashes or itching

These may stem from the body releasing built-up toxins. While not scientifically proven, many practitioners believe detoxification plays a role. Learn more about detox symptoms in the article Earthing Detox Symptoms.

Hydrate well and rest if symptoms appear. Consider shorter sessions at first and consult a healthcare provider if symptoms persist.

4. Metal Toxicity and Allergic Reactions

Soil or grounding products may contain metals such as nickel or copper, which can lead to:

• Skin rashes or hives

• Toe ring dermatitis

• Metal accumulation under the skin in rare cases

Those using grounding mats or patches with metal components are particularly susceptible. Tip: Test grounding devices on a small area of skin before regular use, especially if you have a known metal allergy.

How to Practice Earthing Safely

Follow these simple precautions to enjoy the benefits while minimizing risks:

Safety Checklist:

• Avoid metallic surfaces during grounding

• Use certified earthing mats and devices

• Start with short sessions (15–30 minutes)

• Clean your feet and check for cuts before grounding outdoors

• Test for allergic reactions before using new devices

• Stay away from grounding during thunderstorms

Frequently Asked Questions (FAQs)

How long should you practise earthing?

For optimal benefits, practise earthing 30–60 minutes daily. However, even shorter durations can offer noticeable improvements in mood, inflammation, and energy levels. You can read more on the topic in our article How Long Does It Take to Feel the Benefits of Grounding?.

Is earthing safe for everyone?

Most healthy individuals can practise earthing safely. However, people with immune conditions, metal allergies, or sensitive skin should consult a healthcare professional before beginning. For more details, refer to Can Earthing Help with Fatigue and Energy Levels?.

Can you overdo earthing?

While excessive earthing hasn’t shown major adverse effects, overexposure to contaminated soil or prolonged grounding on unsafe surfaces can lead to infections or allergic responses.

Can you get electrocuted from grounding mats?

Yes—if a mat is plugged into an ungrounded or improperly wired outlet. Always follow the manufacturer’s safety guidelines and never DIY earthing devices. Learn more about grounding product safety in Do Grounding Products Produce EMFs?.
