Following a recent compression stocking fitting course I took through owning a medical supply company, I learned the value of wearing compression socks. As we age, out veins begin to weaken along our return valves which open and close to allow blood to flow down from our hearts and to our extremities such as legs. It is considered medically, that compressing legs and as a result the vascular system in the legs that pressure is increased to allow flow back up the body to the torso and brain for faster more efficient circulation. After learning this, I decided to try compression on a recent trip not only for flying to reduce the risk of deep vein thrombosis also know as blood clots. I noticed that at the end of each day after walking around for many kilometers and hours that I had much more energy than I typically would with regular shoes and socks. I was generally not sore and felt energy 25 % Above my average. Most people who have extended health care through work or self pay plans have at least two pair of compression socks allowed per calendar year if not more. This kind that are covered are usually 20-30 MMHG over the counter or non prescription are sometimes covered. I wear the Cotton Men's knee high with padded sole. So comfortable. Over the counter are typically up to $45.00 per pair. Hand wash and air dry every couple of days. Try them for 3 weeks and not the subtle changes that amount to great feeling. Preventative medicine is the key to longevity. Ex smokers, people on their feet and just everyone can benefit from these. Thanks for your read. These are my personal experiences that I have shared with you.
