What your feet can tell you about your overall health

Our feet, often overlooked in health monitoring, have emerged as a key area of interest in recent health trends. A popular TikTok practice involves standing or moving feet in a tray of Epsom salt for 10 minutes before bedtime. Supporters claim it lowers cortisol levels, boosts serotonin, and promotes better sleep through the effects of magnesium in the salt and grounding.

Susan Jacob, a physiotherapist, explains that the main benefit is muscle relaxation and improved local circulation from warm water, not necessarily the Epsom salt. While there's no robust scientific evidence that sufficient magnesium is absorbed through the skin or that it directly improves sleep, if it helps you unwind, it can be a safe part of your bedtime routine.

The feet serve as an indicator of overall health, often reflecting early signs of various medical conditions. Diabetes can lead to nerve damage, reduced sensation, foot ulcers, and delayed healing. Peripheral arterial disease may cause cold feet and pain during walking. Arthritis can present as foot pain due to sore, stiff, or deformed joints, while heart failure, kidney disease, and liver disease may first manifest as swelling in the feet and ankles.

Maintaining foot health is relatively simple with daily checks. Look for fungal infections causing cracked skin or thickened nails, wash and dry feet thoroughly, and moisturize dry skin. Regular physical activity improves circulation, and well-fitting shoes are crucial for supporting the natural movement of the foot while providing stability and support. Barefoot shoes should be introduced gradually, especially for those with specific foot conditions.

Beyond daily care, wellness practices focused on the feet include reflexology, a technique rooted in ancient traditional Chinese, Indian, and Egyptian medicine. By applying pressure to specific points on the feet and ears, practitioners believe they can gain insights into health issues and bodily problems. Reflexology shoes with nodules or textured insoles designed to apply pressure based on reflexology principles exist, but their effectiveness in treating internal organ conditions or improving overall health remains unproven.

Instead, they can offer temporary relaxation and a massage-like sensation. Grounding, or walking barefoot, is another accessible and cost-effective option, fostering a connection with the earth and potentially improving circulation, reducing pain, and aiding relaxation.
