Patients who have recently developed vitiligo might wonder: "No one in my family has a history of vitiligo, and I usually maintain good lifestyle habits. So why have I developed vitiligo? Is it really due to low immunity?"

 Patients who have recently developed vitiligo might wonder: "No one in my family has a history of vitiligo, and I usually maintain good lifestyle habits. So why have I developed vitiligo? Is it really due to low immunity?"

 In fact, while the onset of vitiligo is closely related to factors such as genetics and autoimmune abnormalities, it is also highly susceptible to the influence of external environmental factors. Let's take a closer look!

1.Frequent Late Nights and Insufficient Sleep

 Under normal circumstances, the body should enter a state of rest and adjustment after 11 PM. Frequent late nights and inadequate rest can easily disrupt the body's immune regulation function and lead to endocrine imbalances, thereby inhibiting the synthesis of melanin and triggering vitiligo. Additionally, staying up late often results in poor mental state and appetite, severely affecting the nervous system. Nervous system disruptions can also interfere with the synthesis of melanocytes in the body.

2.Mental Stress and Psychological Pressure

 Some people experience excessive psychological burden due to pressures from work, studies, or other aspects of life. Long-term mental tension, excessive stress, emotional instability, and other negative stimuli can easily increase melatonin levels, which in turn may induce vitiligo.

 It has been explained that "mental factors can trigger vitiligo because the central nervous system contains melatonin—a substance that inhibits melanin formation." Under normal conditions, melatonin is in dynamic balance with melanocyte-stimulating hormone (MSH) secreted by the pituitary gland. When melatonin levels are too high, it can suppress melanin formation. Clearly, when a person is subjected to malicious mental stimulation, extreme tension, or excessive suppression, melatonin increases, leading to vitiligo.

3.Overexposure to Sunlight and UV Radiation

 Excessive sun exposure and UV radiation can cause melanocytes to become overactive, accelerating their depletion and leading to early decline. This can trigger immune system dysfunction and induce vitiligo. This is why vitiligo often occurs after activities such as travel, sunbathing, or sunburn and frequently appears on exposed areas of the body.

4.Mechanical Skin Injuries

 Skin trauma may trigger vitiligo—known as traumatic vitiligo—a condition that is often overlooked. The causes are complex: it could be due to damage to the local nerve fibers at the injury site, or it might result from the patient being in a prolonged state of tension or "stress" due to chronic illness, which disrupts the neuroendocrine system and affects melanin formation.

5.Picky Eating, Poor Appetite, and Nutritional Imbalances

 Poor dietary habits can trigger or exacerbate vitiligo. Many patients suffer from nutritional imbalances due to picky or selective eating, leading to a relative deficiency of substances necessary for melanin synthesis. This adversely affects the treatment of vitiligo and is one of the reasons why children are particularly susceptible to the condition.

 Smoking, drinking, and consuming spicy, irritating foods, as well as certain allergenic or seafood items, may worsen vitiligo. Patients must pay attention to maintaining a balanced diet; otherwise, they risk not only harming their overall health but also aggravating their condition.

Friendly Reminder:

 There are many treatment methods for vitiligo, but the condition is complex and varies greatly among individuals. Therefore, it is essential to choose the right treatment approach. Visit a reputable dermatology department for comprehensive testing to understand the specific condition. Based on the analysis, an individualized treatment plan tailored to the patient's unique condition, skin type, and other factors can be developed for precise and targeted treatment.
