Which lifestyle choices can lead to alterations in skin integrity? Select all that apply.

Smoking is a significant lifestyle choice that can lead to alterations in skin integrity. The harmful substances in tobacco smoke contribute to various skin issues, including decreased blood flow and oxygen to the skin, which can result in premature aging, a dull complexion, and the development of wrinkles. Additionally, smoking can impair the skin's wound healing capabilities due to its negative effects on circulation and immune function.

Excessive tanning also impacts skin integrity by causing damage to the skin from ultraviolet radiation. This can lead to the breakdown of collagen and elastin, essential components that keep the skin firm and youthful. Over time, excessive tanning increases the risk of skin cancer and can lead to other serious skin conditions.

In contrast, regular exercise and adequate nutrition are associated with improved skin health. Exercise increases blood circulation, which can enhance nutrient delivery to the skin and support its vitality. Adequate nutrition provides the necessary vitamins and minerals that promote skin repair and regeneration, fostering overall skin integrity.
