As spring returns, temperatures rise and nature awakens. However, for people with vitiligo, spring is often a season when the condition is more likely to relapse. Many patients notice that white patches which remained stable during winter may suddenly spread or become more noticeable in spring, causing concern and frustration.
Vitiligo specialist Dr. Liu Yuntao reminds patients that spring fluctuations are not accidental. They are mainly related to three factors: environmental changes, immune system instability, and physical and emotional imbalance. With proper preventive measures, the risk of relapse can be effectively reduced.
1. Environmental Triggers
During winter, lower temperatures and reduced sun exposure mean the skin becomes less tolerant to ultraviolet (UV) radiation. In spring, UV intensity increases rapidly and daylight hours become longer. Without proper sun protection, UV rays can directly affect depigmented areas, impair melanocyte function, and reduce their activity, potentially triggering the spread of white patches. This is one of the most common causes of spring relapse.
2. Immune System Fluctuations
Spring weather is often unpredictable, with significant temperature differences between day and night. At the same time, bacteria and viruses become more active, making people more prone to colds and allergies. These factors can disrupt the immune system. Dr. Liu emphasizes that immune imbalance is one of the core mechanisms behind vitiligo onset and recurrence. When immune function becomes unstable, melanocyte metabolism and regeneration may be affected, leading to disease fluctuation.
3. Physical and Emotional Imbalance
As the weather warms, daily routines and eating habits often change. Irregular sleep, unbalanced diets, and fatigue can disturb the body’s internal balance. In addition, lower atmospheric pressure in spring may contribute to mood swings or anxiety in some individuals. Negative emotions can indirectly influence metabolism and immune function, increasing the risk of recurrence.
Dr. Liu Yuntao reminds patients that spring relapse is preventable and manageable. There is no need for excessive anxiety. By practicing proper sun protection, staying warm to prevent colds, maintaining regular sleep patterns and a balanced diet, continuing standardized treatment, and attending regular follow-up visits, patients can effectively reduce relapse triggers, protect their recovery progress, and navigate the high-risk spring season more smoothly.
