On the annual World Water Day, nonprofit Water.org is raising awareness for those who lack clean water access and pointing to the fact that one child dies from a water-related disease every 21 seconds.
Finally, scar tissue forms to mimic the structure of the skin before the wound to heal the tissue. That said, there are many reasons why a wound is slow to heal. Certain wounds take longer to heal than others (i.e., leg or foot ulcers). Poor nutrition can also damage the body's ability to heal wounds. Too few calories, especially from proteins, and inadequate vitamin (and zinc) intake may affect wound healing. An infected wound harboring a large number of bacteria usually slows the healing process.
The first thing to understand is that wounds heal in four stages. The phases of wound healing are: 1) Hemostasis-clotting and stabilizing of the wound with fibrin and platelets. 2) Inflammation-lasts up to four days. Redness, swelling and warmth occur as white blood cells arrive and prepare to fight infection.
