Older bodies need longer to mend. This reality of aging has been documented since World War I, with the observation that wounds heal slower in older soldiers.
It is because with aging, we consume our प्राण rapidly in activities like copulation, daily chores stress of family life and mindless sleeping and eating habits.
प्राण is our immunity. With aging, disruptions to communication between skin cells and their immune cells slow down this step of wound healing.
This is the reason प्राणवर्धक घी & honey is necessity in old age. Oil massage too.
Old age does not starts at 60. Body starts degradation at 21. 🙂 We realize it much later in 30s when all complications start.
Impaired Epidermal to Dendritic T Cell Signaling Slows Wound Repair in Aged Skin.
“Within days of an injury, skin cells migrate in and close the wound, a process that requires coordination with nearby immune cells. With aging, disruptions to communication between skin cells and their immune cells slow down this step. Discovery suggests new approaches to developing treatments that could speed healing among older people.
Whenever a wound occurs, the body needs to repair it quickly to restore its protective skin barrier. Wound healing is one of the most complex processes to occur in the human body. Numerous types of cells, molecular pathways, and signaling systems go to work over timescales that vary from seconds to months. Changes related to aging have been observed in every step of this process. Both skin cells and immune cells contribute to this elaborate process, which begins with the formation of a scab. New skin cells known as keratinocytes later travel in as a sheet to fill in the wound under the scab.
