Psoriasis & Winter: Why Skin Conditions Worsen in Cold Months

Why Psoriasis Worsens in Cold Weather

Psoriasis is an autoimmune condition affecting 5% of Australians, causing red, scaly, painful skin patches. Cold weather triggers flare-ups through several mechanisms:

• Reduced humidity: Australian winter humidity drops to 30-40%, drying out skin and worsening psoriasis scales
• Less sun exposure: UV rays naturally slow psoriasis cell growth; shorter winter days mean less protective sunlight
• Cold air irritation: Low temperatures damage the skin barrier, triggering immune responses
• Indoor heating: Artificial heating further dries skin, increasing inflammation
• Stress increases: Winter mood changes and seasonal pressure elevate stress, a known psoriasis trigger
• Delayed washing: Less frequent bathing in cold weather allows dead skin and irritants to accumulate

Seniors, people with autoimmune conditions, and those living in cooler regions of Queensland experience the strongest winter psoriasis symptoms.

Psoriasis & Winter: Key Differences from Regular Skin Dryness

Understanding this difference helps you choose the right treatment approach.

Practical Psoriasis Management During the Australian Winter

1. Moisturise Strategically (Not Just Frequently)

1. • Choose thick, ointment-based creams: Products with petrolatum, ceramides, or shea butter.
   • Apply within 3 minutes after bathing: Locks in moisture while skin is damp
   • Moisturise twice daily: Morning and evening, even if skin feels fine
   • Use humectants: Ingredients like glycerin and hyaluronic acid draw moisture into skin
   • Avoid fragrances: Irritants trigger psoriasis flare-ups

2. Modify Your Bathing Routine

• Use lukewarm water: Hot water strips natural oils and worsens inflammation
• Limit baths to 10 minutes: Longer exposure dries skin
• Choose gentle, non-foaming cleansers: Look for “psoriasis-friendly” or “sensitive skin” labels
• Add colloidal oatmeal: Soothes inflamed skin and reduces itching
• Pat dry gently: Never rub, use soft towels

3. Increase Indoor Humidity

Target 45-55% humidity: Ideal for psoriasis management

• Place humidifiers near beds: Maximum overnight benefit
• Clean humidifiers weekly: Prevents mould and bacteria buildup

4. Maximise Safe Sun Exposure

Even in winter, Queensland’s sun provides UV benefits:

• Sunlight exposure: for vitamin D and psoriasis relief
• 10-15 minutes daily: Expose affected areas without sunscreen
• Avoid sunburn: Stop if skin turns red or painful
• Talk to your GP: Some psoriasis medications increase sun sensitivity

5. Manage Winter Stress

Stress triggers 30-40% of psoriasis flare-ups:

• Practice deep breathing: 5 minutes daily reduces cortisol
• Maintain regular sleep: 7-9 hours supports immune balance
• Stay connected: Social support reduces isolation during winter
• Consider therapy: Mindfulness and CBT help manage chronic condition stress

6. Use Medicated Topical Treatments

1. • Vitamin D creams: Slow skin cell overgrowth (prescription from GP)
   • Corticosteroid creams: Reduce inflammation (short-term use only)
   • Salicylic acid: Removes thick scales gently
   • Coal tar: Traditional treatment for scaling (available at Carindale pharmacies)

When Psoriasis & Winter Flare-Ups Need Medical Attention

Don’t wait if you experience:

• Psoriasis covering more than 10% of your body
• Painful, swollen joints (could indicate psoriatic arthritis)
• Signs of infection: yellow pus, fever, increasing redness
• Topical treatments failing after 2 weeks
• Sleep disruption from itching or pain
• Emotional distress affecting daily life
