Shakti Mats are all the rage! But do they bring you any health benefits?

The Shakti Mat is all the rage! It is claimed to offer an “unforgettable experience that targets mind and body tension through acupressure. The nail bed is an ancient healing practice that has been used in India for over 3,000 years. 20 minutes is all it takes. Common uses are for pain and stress relief, muscle tension, soothing headaches and deeper sleep … Join a Shakti community of millions experiencing the benefits of relaxation and rest through this consciously crafted wellbeing tool. 20 minutes is all it takes to decompress and reset your body, unravel your mind and completely transform your sleep. Alleviate and unwind with powerful Eastern acupressure that will give you sanctuary within the demands of the modern lifestyle.”

Yes, that sounds like pure hype. A hopelessly uncritical article for physios is hardly any better; it concluded that “acupressure Mats are not something to be ignored if you have chronic pain, stress and anxiety, trouble sleeping or want to do everything you can to help recover faster. There is definitely some scientific reasoning and research backing up its use although not all research is conclusive or agrees.”

As it turns out, the Internet is full of such hype:

But is there any real evidence, at all?

Not a lot!

Here are two trials that I found:

This study investigated subjective and physiologic responses of lying on a bed of nails (BN) called the Shakti-mat and of listening to relaxing instructions and music. The BN has 6210 sharp-edge 5-mm plastic nails about 5 mm apart.

Design: Thirty-two (32) healthy participants went through four conditions in randomized orders combining BN and relaxing instructions.

Results: The subjective pain ratings on the BN increased immediately and reached a peak within 30 seconds. The pain then subsided gradually, indicating a habituation effect. Self-rated relaxation increased over time in all conditions. Systolic and diastolic blood pressures were higher, heart rate was slower, and there was more high-frequency power heart rate variability (HRV), and signs of increasing circulation in the back on the BN. The relaxation instruction especially affected breathing and the HRV-indices standard deviations of normal interbeat intervals and low-frequency power, both known to be responsive to slow breathing. There were no differences in saliva cortisol.

Conclusions: Healthy participants habituated to the induced pain on the BN and were able to subjectively relax. When on a BN, signs of both sympathetic and parasympathetic nervous system activity were observed. The pain may hypothetically have triggered a parasympathetic response.

Self-care treatments with bed of nails or spike mats have gained increased popularity world-wide; advertised as a method for pain reduction and wellbeing. Scientific studies regarding effects are still lacking. The aim of the present study was to investigate if daily relaxation on a spike mat for three weeks could induce beneficial effects. Participants were 36 individuals suffering from muscle ten-sion pains in their back or/and neck. They were randomly assigned to a control group or an experimental group, who were treated with 15 minutes daily rest during three weeks on the spike mat. Significant reduced experi-enced worst pain intensity was found. There were no effects on normal pain intensity, opti-mism, anxiety, depression, stress, energy, or sleep quality. The participants appreciated the treatment, but their enthusiastic verbal reports of experienced beneficial effects could not be verified in the statistical analyses. The reduction of worst pain may be explained by the gate-control theory, where competing stim-uli applied over the affected area produce a pain reduction. It can also be an effect of place-bo or the relaxation. More research on relax-ation on a spike mat is needed before its possi-ble effects can be confirmed. No negative effects were found in the present study, but it has to be remembered no studies investigating risks for treatment on spike mats exist.
