Swimming pool water allergy

With the arrival of summer, in addition to the various kinds of fruits that we love, various water-related sports are also sought after by people, among which swimming is the most popular. Swimming is a type of aerobic exercise. Girls like swimming because it is an exercise that can slim the whole body and is useful in maintaining a perfect figure in the long run. Swimming is good, but we need to pay attention to whether the pool water is clean. What should we do if we are allergic to the pool water?

If the swimming pool water is not replaced and disinfected frequently, many viruses, bacteria, and microorganisms will remain. People with sensitive skin will easily develop allergies and skin itching after entering the pool water and being soaked, which is very unbearable and uncomfortable. If it is caused by allergies, please take anti-allergic drugs in time. Generally, taking it 1-2 times will produce obvious results.

Pruritus is a symptom of skin disease characterized by only skin itching without primary skin lesions. According to the scope and location of skin itching, it is generally divided into two categories: systemic and localized.

Clinical manifestations

1. Systemic pruritus

It is more common in adults, and the itching often starts from one place and gradually spreads to the whole body. It is often paroxysmal, especially at night. In severe cases, it presents as persistent itching with paroxysmal aggravation. Drinking, coffee, tea, mood changes, spicy food stimulation, mechanical scratching, warm bedding, and even some suggestion can induce the onset and aggravation of itching. Scratches, blood crusts, pigmentation, and even eczematous changes, lichenoid changes, pyoderma, lymphangitis, and lymphadenitis are often secondary.

(1) Senile pruritus is common in the elderly, with the trunk being the most itchy. It is mostly caused by factors such as sebaceous gland dysfunction and dry skin. In female patients, it may be a manifestation of postmenopausal syndrome.

(2) Winter pruritus is more common in adults, but children can also suffer from it. It often occurs in late autumn and winter when the temperature changes dramatically. Patients often begin to itch when they enter a warm room or take off their clothes before going to bed.

(3) Summer pruritus is often caused by dampness and heat. Increased sweating in summer can aggravate the itching.

2. Localized pruritus

(1) Anal pruritus is more common in middle-aged men, and children with pinworm infection may also suffer from the disease. The itching is usually confined to the anus and the surrounding skin, but can sometimes spread to the perineum, vulva, and scrotum. Frequent scratching may cause the anal skin to thicken, but it may also present as secondary damage such as lichenification or eczema-like changes.

(2) Scrotal pruritus: The pruritus is mainly confined to the scrotum, but may sometimes also affect the penis, perineum and anus. Due to constant scratching, lichenification, eczematous changes and secondary infection may occur.

(3) Vulvar pruritus: Itching often occurs on the labia majora and minora. Due to constant scratching, the labia majora often have thickening and infiltration of the skin, and the clitoris and vaginal mucosa may have redness, swelling and erosion.
