One of the most common questions we get is whether you can use your regular bed sheets over a grounding sheet underlay or earthing bed mat. The good news? Yes, you can use most standard bedding materials — but some are better than others when it comes to conductivity, comfort, and overall grounding performance. The only real barrier to grounding is thick underlays or mattress protectors, which can block the flow of electrons.

Understanding how different sheet materials interact with your grounding setup can help you get the most out of your Urban Hippee grounding products. Let’s break it down in detail.

Do Bed Sheets Block Grounding?

This is a common concern, and the short answer is no — grounding still works even with a bed sheet on top. All bed sheet materials allow some level of grounding, regardless of thread count or fabric type. However, the level of conductivity can vary depending on the material. The only significant issue arises when thick mattress pads, underlays, or waterproof protectors are used between your body and the grounding product — these can block conductivity almost entirely.

Even synthetic sheets, while not ideal, won’t completely block the grounding signal — especially if your grounding sheet or mat is made with high-conductivity materials like stainless steel or carbon. That said, for optimal results, we still recommend using sheets made from natural fibres like cotton, bamboo, or linen.

In fact, our Premium Grounding Underlay Sheets are designed specifically to work under your normal fitted sheet, making it easy to stay grounded without changing your sleep setup.

Best Bed Sheet Materials to Use Over Grounding Sheets or Mats

Here’s a breakdown of the most common bed sheet materials and how they perform with grounding sheets or earthing mats. All of these can work, though some provide better conductivity than others:

• Cotton (100%) – Highly recommended. Breathable, moisture-friendly, and widely used. Great for conductivity.

• Bamboo – Soft, sustainable, and naturally conductive. Excellent choice for grounding.

• Linen – Breathable and durable. Performs well and softens over time.

• Hemp – Eco-friendly and strong. A great option with good grounding performance.

• Silk – Naturally conductive and luxurious. Works surprisingly well when pure.

• Tencel – Soft and smooth. Performs decently if not blended with too many synthetics.

• Polyester – Fully synthetic but still allows grounding in most cases, especially with high-conductivity grounding materials underneath.

• Flannelette (Cotton or Polyester) – Works well, especially when not too thick. Cotton-based flannelette is preferred.

• Fleece – While fully synthetic, it can still work over a grounding underlay, though less ideal.

• Microfibre – Similar to fleece. Synthetic, but still usable if layering is correct.

• Jersey Knit (Cotton or Cotton Blend) – Stretchy and breathable. Works fine when cotton-based.

• Modal or Viscose – Plant-based synthetics. Moderate conductivity — acceptable when not overly processed.

• Sateen – A weave rather than a material; if made from cotton, it works well.

All of these can work over Urban Hippee grounding sheets and mats, with the key variable being what’s layered underneath them. Avoid mattress toppers or protectors that separate your body from the grounding layer, as those are the only things that significantly block conductivity.

Common Bed Sheet Materials — And Why They All Work

All common bed sheet materials can work effectively with our grounding underlays and mats. While natural fibres like cotton and bamboo generally perform better in terms of conductivity, even synthetics such as polyester or flannelette blends have been shown to allow grounding in real-world use — particularly when paired with high-conductivity materials like stainless steel fibre or carbonized leatherette. Again, the only true barrier tends to be thick mattress toppers or dense underlays placed between your body and the grounding product.

Tips to Maximise Grounding While Using a Sheet

• Do not use mattress toppers or synthetic protectors between your body and the grounding underlay — these are the main culprits when grounding fails.

How to Layer Bedding With a Grounding Product

To ensure your grounding product works effectively, follow this layering order:

1. Mattress

2. Grounding sheet or mat (underlay style)

3. Natural fibre fitted sheet (cotton, bamboo, etc.)

4. You — with or without pyjamas made of natural material

Avoid inserting synthetic layers, thick mattress pads, or protectors in between, as these are the only things that can block grounding.

Conclusion: Use the Right Sheets for Effective Grounding

So yes, you can absolutely use your own bed sheets over a grounding underlay or earthing mat — just make sure they’re made from the right materials. Natural fibres like cotton, bamboo, linen, and hemp allow for proper conductivity, while synthetics like polyester or fleece still generally allow grounding. The only real issue is with layers like mattress protectors or underlays that sit between your body and the grounding surface.

Knowing the properties of your bedding materials can help you get the most out of your earthing routine, especially while sleeping.

Whether you’re using grounding sheets, bed mats, or accessories, choosing the right fabric on top makes a big difference — and just as importantly, avoiding thick insulating layers underneath keeps your connection to the Earth strong, night after night.
