Which factor affects skin integrity?

• A. Adequate circulation
• B. Sleep quality
• C. Vitamin supplements
• D. Eye color

Answer: (A)

Adequate circulation is essential for skin integrity because blood flow delivers oxygen and nutrients to skin cells, supports immune function, and enables waste removal, all of which fuel repair and maintain healthy tissue. When perfusion is good, skin stays resilient, maintains color and turgor, and heals more efficiently after minor injuries. Poor circulation, on the other hand, reduces oxygen delivery and nutrient supply, slows healing, and increases the risk of tissue breakdown and ulcers. Sleep quality can influence healing overall but isn’t the direct determinant of skin integrity in the same way perfusion is; vitamin supplements may help if there’s a deficiency but aren’t universal determinants; eye color has no impact on skin integrity.
