Does Weather Affect Psoriasis in Australia?
Share
Psoriasis is a complex, chronic skin condition that affects millions of people worldwide—including many Australians. While genetics and immune system dysfunction are central to its cause, external triggers also play a role in symptom flare-ups. Among these triggers, weather stands out as one of the most significant. But does weather affect psoriasis in Australia? The short answer is yes. Let’s dive deeper into how different Australian climates can impact psoriasis symptoms and what you can do to manage them.
Understanding Psoriasis and Its Triggers
What Is Psoriasis?
Psoriasis is an autoimmune skin condition that causes the body to produce skin cells more rapidly than usual. This leads to thick, scaly patches of skin that may be red, itchy, or painful. The most common form is plaque psoriasis, but other types include guttate, inverse, pustular, and erythrodermic psoriasis.
Common Triggers for Psoriasis Flare-Ups
Although psoriasis is not caused by external factors, these can worsen symptoms:
-
Stress
-
Infections
-
Certain medications
-
Skin injuries
-
Lifestyle factors
-
Weather and climate changes
Among these, climate and weather are uniquely relevant in a country like Australia, where conditions vary greatly from tropical heat to chilly winters.
Does Weather Affect Psoriasis in Australia?
Australia’s vast geography means people experience a wide range of climates, from the tropical north to the temperate south and the dry interior. Each climate zone can affect psoriasis differently.
Summer in Australia: A Double-Edged Sword
Benefits of Sunlight
Moderate sun exposure can actually be beneficial. Ultraviolet (UV) rays from the sun can slow the rapid growth of skin cells, easing symptoms. Many people notice improvement during sunnier months.
-
Natural UV therapy (without sunburn) may reduce redness and scaling.
-
Vitamin D production increases, which may boost immune regulation.
Risks of Heat and Humidity
However, excessive heat and sweating can irritate the skin and trigger flare-ups.
-
Sweat can mix with bacteria and clog pores.
-
Heat rash or sunburn may cause new patches (Koebner phenomenon).
-
Air conditioning can dry out the skin, causing further irritation.
Winter in Australia: A Tough Season for Many
Cold air, low humidity, and indoor heating can wreak havoc on psoriasis.
-
Skin becomes dry and cracked, which exacerbates scaling.
-
Lack of sunlight reduces UV exposure, potentially worsening symptoms.
-
People are often less active and more stressed during winter, adding to the burden.
Those in southern states like Victoria and Tasmania often report more winter flare-ups than those in the tropical north.
Regional Weather Patterns and Psoriasis Impact
Let’s break down how specific regions in Australia may affect individuals with psoriasis.
Tropical North (e.g., Darwin, Cairns)
-
Hot and humid year-round
-
High UV index may help with symptom management
-
But excess sweating and skin infections may worsen flare-ups
Temperate South (e.g., Melbourne, Hobart)
-
Cool to cold winters and moderate summers
-
Dry, windy weather in winter may cause cracking and flaking
-
Flare-ups more common in colder months
Arid Inland Areas (e.g., Alice Springs)
-
Hot days, cold nights, and very low humidity
-
Dry air leads to moisture loss in skin
-
Requires diligent moisturising to prevent worsening symptoms
Coastal Cities (e.g., Sydney, Brisbane, Perth)
-
Generally milder and more balanced weather
-
Beneficial for people with psoriasis who prefer moderate sun and humidity
-
Less severe fluctuations may mean more stable symptoms
How to Manage Psoriasis in Different Australian Weather Conditions
General Skincare Tips Year-Round
-
Use fragrance-free moisturisers daily
-
Avoid long, hot showers that strip natural oils
-
Pat skin dry and moisturise immediately after bathing
-
Wear loose-fitting, breathable clothing
Summer Skincare for Psoriasis
-
Use SPF 30+ sunscreen to avoid burns
-
Stay hydrated to keep skin plump and moist
-
Shower after sweating to reduce irritation
-
Get short, safe exposure to morning or late afternoon sun
Winter Skincare for Psoriasis
-
Invest in a humidifier for indoor heating
-
Use thicker, ointment-based moisturisers
-
Layer up with soft fabrics like cotton
-
Consider phototherapy under medical guidance if natural sunlight is scarce
Do Seasonal Changes Impact Psoriasis Treatments?
Yes. As the weather changes, so might the effectiveness of certain treatments. For instance:
-
Topical treatments may need to be richer in winter and lighter in summer.
-
Phototherapy may be more necessary in winter months when natural UV exposure is low.
-
Lifestyle adjustments—like diet and exercise—become more important when weather limits outdoor activities.
Consult with a healthcare provider or dermatologist to adapt your treatment plan seasonally, especially if symptoms significantly change with the weather.
Natural Remedies and Supplements for Weather-Related Psoriasis
While prescription treatments are essential for many, some people find natural approaches helpful alongside their regimen:
-
Omega-3 supplements: Reduce inflammation and may help soothe dry skin.
-
Vitamin D: Especially useful during winter; consult your doctor for safe dosing.
-
Aloe vera gel: Cooling and hydrating—great for summer flare-ups.
-
Colloidal oatmeal baths: Soothing in both hot and cold conditions.

When to See a Specialist

-
Book a consultation with a dermatologist

Discuss phototherapy options if you can’t get enough sun
-
Ask about weather-adjusted treatment plans
It’s essential to track your symptoms through the seasons so your healthcare provider can better understand your triggers.
