Another health and wellness trend has broken the internet. Influencers across the world are dousing their belly buttons and armpits with a supplement spray that they believe can relieve stress, improve sleep and ease muscle soreness. And no points for guessing but this apparent life-altering product is Magnesium spray. "I cannot emphasize the importance of using a magnesium spray every single day," Mandana Zarghami, a Miami influencer, said in a viral video on TikTok. "During the day I'll spray it under my arms and in my belly button," she added. She further underscored that she repeats the practice at night when she also puts it on the bottom of her feet.Why Magnesium? Magnesium is an electrolyte that boosts energy and bone health. It supports neurological and cardiovascular health along with improving sleep. A deficiency of this nutrient is linked to chronic health conditions such as diabetes, hypertension, heart disease, stroke, osteoporosis, and migraines. Magnesium oil is one of its supplements. Interestingly, in her video, she confessed that she initially popped magnesium pills but turned to the spray after feeling nauseous from them.Another online influencer, Amalia Falck, who also owns a herbal wellness product business regularly lathers her belly button with the oil and says it helps gut health, migraine menstrual cramps and body odour. Another thing, influencers swear by is massaging Castor oil in my belly button. The oils are commonly applied to the navel, armpits and soles of the feet because those areas are believed to be more vascular and therefore contribute to enhanced absorption.Potential Benefits Of Magnesium OilNeuropathy Relief: A 2023 study on patients with chronic kidney disease found that daily application of magnesium oil eased neuropathic pain, although it did not significantly increase magnesium levels.Fibromyalgia Symptoms: A 2015 study reported that spraying magnesium chloride on limbs reduced pain and other symptoms associated with fibromyalgia.Wound Healing: Rodent studies in 2023 suggested that magnesium creams might accelerate wound healing. Before You Spray Magnesium Oil, Keep It CleanThe belly button marks the exact spot where your umbilical cord was once attached—the vital connection that provided oxygen and nutrients in the womb. Once you started breathing, eating, and discharging waste on your own, this cord was no longer needed. What remains is a mark, a reminder of your months in your mother’s womb. However, it often gets ignored as you grow up. And there is nothing wrong with that. Your belly button does not require a special skincare routine, but neglecting its hygiene can lead to a buildup of bacteria, potentially causing a smelly discharge. But generally, a discharge from your belly button is normal and colourless. According to experts, normal discharge is typically clear or light-coloured, has a slight odour (similar to sweat), and has no pain or redness around the navel. Experts say that the most common funk you might encounter in your belly button is a bacterial or fungal infection. This occurs due to poor hygiene, excessive sweating, or trapped moisture. Other conditions include navel piercings, cysts, and skin conditions like eczema or psoriasis. People with diabetes are particularly susceptible to fungal infections such as candidiasis if their blood sugar isn't under control, according to a 2019 review in the Journal of Clinical Medicine.
