Vulvar itching can be a distressing symptom, and understanding its potential causes is crucial for effective management. The sensation of itching in the vulvar area, particularly when it disrupts sleep, can stem from various factors, including infections, irritants, skin conditions, and hormonal changes.

1. Infections: One of the most common causes of vulvar itching is a yeast infection, which can lead to intense itching, irritation, and sometimes a thick, white discharge. Bacterial vaginosis and sexually transmitted infections (STIs) like trichomoniasis can also cause similar symptoms. It's important to consider these possibilities, especially if there are any accompanying symptoms like unusual discharge or odor.

2. Irritants: Many women experience vulvar itching due to irritants. This can include soaps, detergents, fabric softeners, or even certain types of toilet paper. If you've recently changed any personal care products or laundry detergents, this could be a contributing factor. Additionally, tight clothing or synthetic fabrics can trap moisture and create an environment conducive to irritation.

3. Skin Conditions: Conditions such as eczema or lichen sclerosus can also cause vulvar itching. Eczema is characterized by dry, itchy skin, while lichen sclerosus can lead to white patches and thinning of the skin in the genital area. If you have a history of skin conditions, this could be relevant.

4. Hormonal Changes: Hormonal fluctuations, particularly during menopause or breastfeeding, can lead to vaginal dryness and vulvar itching. This is due to decreased estrogen levels, which can affect the vaginal and vulvar tissues. If you are experiencing other symptoms of hormonal changes, such as hot flashes or mood swings, this could be a factor.

5. Hydration and Diet: You mentioned a change in your water intake, which can impact overall hydration and potentially contribute to dryness in the vulvar area. While this is less common, ensuring adequate hydration is important for maintaining healthy mucous membranes.

Given your symptoms of intense itching, especially at night, it is advisable to consult a healthcare provider for a thorough evaluation. They may perform a physical examination and possibly recommend tests to rule out infections or other underlying conditions.
In the meantime, here are some general management strategies you can consider:
- Avoid Irritants: Switch to mild, unscented soaps and avoid douching or using perfumed products in the genital area. Opt for cotton underwear and loose-fitting clothing to reduce irritation.

- Moisturize: If dryness is a concern, consider using a water-based lubricant or vaginal moisturizer to alleviate discomfort.

- Cool Compresses: Applying a cool compress to the affected area can provide temporary relief from itching.

- Over-the-Counter Treatments: Antihistamines may help reduce itching, especially if it is related to an allergic reaction. However, consult with your healthcare provider before starting any new medication.

- Maintain Hygiene: Regular bathing with gentle cleansing can help, but avoid excessive washing, which can strip the skin of natural oils.

In conclusion, vulvar itching can arise from a variety of causes, and identifying the underlying issue is key to effective treatment. If symptoms persist or worsen, seeking medical advice is essential to ensure proper diagnosis and management.
