Experts have begun to question the growing popularity of using magnesium products on the feet as a means to improve sleep, especially as the trend continues to gain traction on platforms like TikTok. While magnesium is well-established as an essential mineral for various bodily functions, including heart health, nerve function, and blood sugar regulation, its effectiveness when applied topically to the feet for sleep improvement remains debated.
The trend centers on the idea that applying magnesium lotion, oils, or sprays to the soles of the feet can enhance sleep quality and potentially balance hormones like insulin and cortisol. This has led to considerable online interest, with many users sharing their experiences and encouraging others to try the method. One particularly popular video from a user who claimed that regular use of magnesium products led to better sleep and improved restlessness has received thousands of likes and shares, sparking both curiosity and skepticism among health professionals.
Dr. Brendan Camp, a dermatologist based in New York, has raised doubts about the efficacy of these magnesium products for sleep. In an interview with Fox News Digital, he explained that the thick skin on the soles of the feet may not allow for the effective absorption of topical magnesium products. This means that much of the product may remain on the skin’s surface rather than entering the bloodstream, where it could potentially influence sleep patterns. Dr. Camp emphasized that more research is needed to determine whether the practice has any significant impact on sleep quality.
In addition, Dr. Wendy Troxel, a sleep psychologist at the RAND Corporation, suggested that the benefits observed in users might be due to the act of foot massage rather than the magnesium itself. She noted that massaging the feet as part of a nightly routine can activate the body’s relaxation response and promote sleep, independent of the product used. Troxel highlighted that while the idea of using magnesium for sleep is tempting, the current scientific evidence does not support it as a reliable sleep aid. Instead, she recommended focusing on evidence-based sleep health practices, such as maintaining a consistent bedtime schedule, avoiding technology before bed, and cultivating a calm and dark sleeping environment.
Troxel also warned that some symptoms, such as leg cramps or tingling sensations, which some users claim to have experienced with magnesium products, could be indicators of restless legs syndrome, a sleep disorder often linked to iron deficiency. She advised individuals experiencing these symptoms to consult a doctor before relying on unproven remedies like magnesium lotion. Overall, the experts are urging people to approach the trend with caution, emphasizing the importance of scientific validation before adopting new health practices.
