Winter Itch: and Managing Dry Skin Issues

Itchy skin occurs every winter?

Hello: Every time winter approaches, my body (inner thighs, abdomen, waist, calves, etc.) starts to itch.
The itching can become so intense at night that I unconsciously scratch, resulting in my skin appearing to have large red rashes, which is quite alarming! Moreover, it seems to be getting worse; earlier, I would only itch when the temperature was around 10 degrees Celsius, but now I start itching at 15 to 16 degrees.
However, living in Kaohsiung, I never experienced this issue before going to Taipei for my studies, and after returning, every time the weather gets cold, I start this itching nightmare again.
Therefore, I would like to ask: 1.
Is this a matter of my constitution, or is it a medical condition? Is there a way to completely cure it? What should I pay more attention to in my daily diet and bathing habits? 2.
I apply body lotion in winter due to dry skin, but why does it seem to make the itching worse? 3.
If I go to a dry and cold region in Europe, will my skin become even drier and itchier? Thank you for taking the time to answer my questions.

Based on your description, it seems you have seborrheic dermatitis (commonly known as winter itch).
The general care for seborrheic dermatitis follows the "three don'ts" policy: 1.
Do not wash with water that is too hot.
2.
Do not soak for too long.
3.
Do not use soaps with strong cleansing properties.
These guidelines are intended to prevent the removal of excessive skin oils.
When the skin lacks sufficient sebum, its protective and moisture-retaining abilities are naturally compromised, and combined with cold, dry weather, seborrheic dermatitis can manifest.
When choosing moisturizing products, look for ingredients that can help retain moisture, such as glycerin, urea, propylene glycol, sodium lactate, hyaluronic acid, and Sodium PCA.
Additionally, it is important to incorporate occlusive agents like petroleum jelly, mineral oil, paraffin, soybean oil, and stearic acid to reduce moisture loss from the skin.
For normal or oily skin, a moisturizing lotion is appropriate, while for dry or very dry skin, a moisturizing cream is more suitable.

More Info

Winter itch, or pruritus, is a common issue many people face as temperatures drop and humidity levels decrease. This condition is often exacerbated by dry indoor heating and cold outdoor air, leading to skin that feels tight, itchy, and uncomfortable. Your symptoms, particularly the intense itching and the appearance of red patches on your skin, suggest that you may be experiencing a form of eczema or dermatitis, often triggered by the dry winter conditions.

1. Understanding the Cause: The itchiness you describe is likely related to dry skin, which can be influenced by several factors, including environmental conditions, personal habits, and underlying skin conditions. In your case, it seems that your skin has become more sensitive to the cold and dry air since moving back to Kaohsiung. This could be due to a change in your skin's barrier function, which may have been compromised by environmental factors or lifestyle changes. It’s important to note that while some individuals may have a genetic predisposition to dry skin or eczema, others may develop these issues due to changes in their environment or skin care routines.

2. Skin Care Routine: To manage and alleviate your symptoms, consider the following recommendations:
- Moisturizing: While you mentioned using body lotion, it’s crucial to choose a product that is specifically designed for dry skin. Look for creams or ointments that contain ingredients like ceramides, hyaluronic acid, or glycerin, which help to retain moisture. Applying moisturizer immediately after bathing can help lock in hydration.

- Bathing Habits: Be mindful of your bathing routine. Hot showers can strip your skin of its natural oils, leading to increased dryness and irritation. Opt for lukewarm water and limit your shower time. Additionally, consider using a gentle, fragrance-free cleanser instead of traditional soaps, which can be harsh on dry skin.

- Humidity Levels: Using a humidifier in your home can help maintain moisture in the air, which can be beneficial for your skin during the winter months.

3. Diet and Lifestyle: Your daily habits can also impact your skin health. Ensure you are drinking plenty of water to stay hydrated from the inside out. A balanced diet rich in omega-3 fatty acids (found in fish, flaxseeds, and walnuts) can also support skin health. Avoiding known irritants, such as harsh detergents or certain fabrics, can further help manage your symptoms.

4. Potential for Worsening Conditions: If you travel to colder, drier climates, such as parts of Europe, your skin may indeed react more severely due to the increased dryness. It’s advisable to prepare by bringing along your moisturizing products and possibly consulting a dermatologist before your trip for tailored advice.

5. When to Seek Help: If your symptoms persist or worsen despite these measures, it may be beneficial to consult a dermatologist. They can provide a proper diagnosis and may recommend treatments such as topical corticosteroids or other medications to help manage inflammation and itching.

In summary, winter itch is a multifaceted issue that can often be managed with appropriate skin care and lifestyle adjustments. By understanding the underlying causes and implementing a comprehensive skin care routine, you can significantly improve your comfort and skin health during the colder months.
