BFST® is the Better Choice
Hot Packs are the "old school" method for promoting blood flow. Heat up the affected area and your body will respond with increased blood flow to keep the area cool. The trouble with the hot pack solution is that they use conductive heat meaning that they heat your body from the outside in. First the hot pack heats your skin and then heat leaks down to the fat tissue beneath the skin and then heat moves from the fat into the underlying tissue. This is called conductive heating. Conductive heating is good in theory, but it is unfortunately quite ineffective.
Our skin and our fat are protective layers to our underlying tissue. They are designed in large part to insulate our insides from external changes in temperature and they do that very well. As you heat your skin, blood flow increases there to whisk away the heat and protecting the underlying tissue. The same thing happens in the fatty layer. In reality, there is very little heat that actually can make it through the skin and fat into the underlying tissue. By comparison, conductive cooling (or cryotherapy) to control pain and swelling is more effective for that purpose because the cooling at least reduces the blood flow and as the blood flow lessens, the effective ability for the body to remove the cold becomes less.
If your desire is to truly stimulate blood flow and relax underlying muscle tissue, BFST® is a far superior choice. BFST® treatments are designed to stimulate blood flow in the underlying tissues while minimizing the amount of surface heating. BFST® provides much better results than the traditional conductive heating approach.
