Which of the following can cause increased hair growth?

Increased hair growth, or hirsutism, can be influenced by hormonal changes, which often occur during periods of elevated stress. When a person is under significant stress, the body may produce higher levels of androgens, the male hormones that can lead to increased hair growth in women. This hormonal imbalance is more pronounced in some individuals, resulting in noticeable changes in hair growth patterns.

While other options listed can affect the body in various ways, they do not typically have a direct effect on hair growth comparable to stress. For example, depression can lead to changes in appetite and lifestyle choices that might affect overall health, but it does not specifically trigger the hormonal fluctuations that promote hair growth. Sun exposure is linked more to skin changes and can lead to other skin issues rather than influencing hair growth directly. Diabetes can cause various complications, including skin-related issues, but its relationship with hair growth is more complex and does not directly cause increased hair growth as stress does. Therefore, stress is the most relevant factor connected to increased hair growth among the choices provided.
