SunSmart Summer: Cancer Council UV Protection Guide

Australian summers are not merely warm, but harsh as well. While most people automatically relate sun damage with the beach and the heatwaves associated with summer, the reality is that sun damage can sometimes occur even on relatively cool days.

Therefore, Cancer Council Australia continues to share a clear message: sun protection is a daily habit, not a seasonal one.

In this guide, we will talk about the Cancer Council’s Sun Smart guidelines and explain the reason behind UV radiation levels being so high, and examine how hemp hats and clothing can be part of this Sun Smart approach.

Australia’s Extreme UV Environment

Australia also has one of the highest rates of skin cancer in the world, and the basic factor that contributes to this is the harsh level of UV radiation we experience.

Therefore, Australian UV environment is considered to be so extreme:

• The ozone layer is thinner over the southern hemisphere, and UV is more intense.
• “UV index reading is frequently Very High or Extreme, even on days when temperatures do not seem particularly high.”
• In addition, UV rays reflect off sand, water, concrete, and pavement, etc.
• UV radiation can still be harmful during winter and cloudy weather, because UV passes through cloud cover.
• Australia’s outdoor lifestyle means people are exposed repeatedly over time, leading to cumulative skin damage.
• People living in regional and rural areas often experience higher UV exposure due to farming, construction, and outdoor work.

The result is clear: in Australia, UV safety is not optional, it’s essential.

Cancer Council Australia’s Consistent Public Health Message

Cancer Council Australia has maintained one of the strongest and most consistent skin cancer prevention messages globally. Their approach is based on evidence, long-term studies, and simple behavioural strategies.

Their key public health message includes:

• Skin cancer is one of the most preventable cancers
• Sun protection is recommended whenever the UV Index is 3 or above
• Long-term prevention relies heavily on behaviour change
• Protection is encouraged for all age groups, especially children
• The best results come from combining physical barriers (clothing, hats, shade) with chemical barriers (sunscreen)
• Schools, workplaces, parks, and public spaces are strongly encouraged to adopt SunSmart policies
• Seasonal awareness campaigns reinforce consistent prevention habits

In other words, sun safety isn’t about fear, it’s about smarter daily decisions.

Cancer Council Australia’s Sun-Protection Principles

Understanding the SunSmart Framework

The SunSmart Framework is the Cancer Council’s well-known guide for reducing UV exposure. It promotes a layered protection method rather than relying on one single product like sunscreen. The framework is designed to be simple, memorable, and practical for daily use.

It’s built around five simple actions:

Slip, Slop, Slap, Seek, Slide

Each step targets a different area of sun exposure, helping protect skin, eyes, and overall health. When combined, they significantly reduce the risk of sunburn, premature ageing, and skin cancer.

Slip: Slip on Protective Clothing

Clothing is one of the most effective forms of UV protection because it blocks sunlight before it reaches the skin. Unlike sunscreen, clothing doesn’t wear off and can provide consistent coverage during long outdoor activities.

Cancer Council encourages:

• Wearing long-sleeved shirts made from tightly woven fabric
• Choosing UPF-rated garments for stronger protection
• Using lightweight but dense materials for summer comfort
• Wearing darker colours, which block more UV than pale shades
• Opting for loose-fitting clothing for airflow
• Covering shoulders and arms, which reduces melanoma risk

Protective clothing is particularly useful for people who work outdoors or spend long hours in the sun.

Slop: Slop on Sunscreen

Sunscreen is a critical tool for protecting exposed skin, especially areas like the face, neck, and hands. However, sunscreen only works well when applied correctly, and many people unknowingly use too little.

Cancer Council sunscreen guidelines include:

• Use SPF 50+ broad-spectrum sunscreen
• Apply at least 20 minutes before sun exposure
• Reapply every two hours, or after swimming and sweating
• Apply generously and evenly
• Don’t forget the ears, neck, hairline, and the top of the feet
• Suitable for all skin types, including sensitive skin

Sunscreen should always be treated as part of a routine, not a once-a-day product.

Slap: Slap on a Hat

Hats are one of the simplest and most effective physical barriers against UV exposure. They protect the scalp, forehead, ears, and parts of the neck, areas that are highly prone to sun damage and often forgotten during sunscreen application.

Cancer Council recommends hats such as:

• Wide-brim hats (minimum 6–7.5 cm brim for adults
• Bucket hats
• Legionnaire hats
• Structured hats like fedoras, if brim coverage is sufficient

For best protection:

• Hats should fit securely to prevent sun gaps
• Chin straps improve stability in wind
• Dark underbrims reduce UV reflection
• Avoid baseball caps for prolonged sun exposure

A wide-brim hat provides shade where sunscreen alone may not be enough.

Seek: Seek Shade

Shade reduces direct UV exposure and helps prevent heat stress. While shade doesn’t block all UV radiation, it significantly lowers risk, especially when paired with hats, sunglasses, and sunscreen.

Cancer Council recommends:

• Staying in shade between 10am and 4pm
• Using shade sails, umbrellas, verandas, and trees
• Planning activities outside peak UV times
• Creating shaded play areas at home and schools
• Using portable shade options while travelling

If you can’t avoid the sun, finding shade breaks can dramatically reduce overall UV load.

Slide: Slide on Sunglasses

UV exposure doesn’t only affect skin, it can damage eyes over time and contribute to cataracts and other eye conditions. Sunglasses are essential for anyone outdoors, particularly near reflective surfaces like water and sand.

Cancer Council recommends sunglasses that:

• Meet Australian UV protection standards
• Have wraparound designs for side protection
• Include polarised lenses to reduce glare
• Provide reliable protection during beach or outdoor sport activities

Sunglasses are an often-overlooked part of sun safety, but they are just as important as sunscreen.

Role of Hats in Sun Protection

Hats provide targeted protection for some of the most sun-sensitive parts of the body. Facial skin is thinner and more prone to damage, while the scalp is often exposed and difficult to protect with sunscreen.

Key benefits of wearing hats include:

• Reducing direct UV radiation on facial skin
• Creating shade for the ears and neck
• Preventing scalp sunburn and hairline damage
• Enhancing sunscreen performance by reducing UV intensity
• Reducing premature ageing such as wrinkles and pigmentation
• Providing crucial protection for children and outdoor workers

A good hat is one of the easiest long-term investments in skin health.

The Growing Popularity of Hemp Hats

Hemp hats are becoming increasingly popular in Australia due to their breathable texture and natural aesthetic. As more people look for sustainable fashion choices, hemp has gained attention as a practical and environmentally friendly material.

Hemp hat popularity is rising due to:

• Increased awareness of eco-friendly clothing
• Demand for breathable headwear in tropical climates
• Preference for natural fibres over synthetic fabrics
• Growth of environmentally conscious consumer habits
• Style versatility for travel, beach, and casual wear
• Popularity of artisan and handmade fashion designs

For Australians dealing with hot summers, hemp offers a balance of comfort and functionality.

Clarification on Hemp & Cancer Council Guidance

Cancer Council Australia does not officially promote one fabric type over another. Their focus is on performance, design, and coverage. That means hemp is not recommended simply because it is hemp; it must still meet protective standards.

Cancer Council guidance is based on:

• Brim width and face coverage
• Fabric weave and density
• Colour and dye process
• Hat structure and stability
• UPF testing and product reliability

Hemp is acceptable as long as it offers strong UV resistance and meets SunSmart requirements.

Scientific Evidence: Natural UV Resistance of Hemp Fibre

Why Hemp Can Block UV Radiation

Hemp has natural properties that make it effective at reducing UV penetration. Its fibre composition and density create a physical barrier that blocks or scatters UV radiation.

Hemp blocks UV due to:

• High lignin content that absorbs UV rays
• Natural pigments that improve UV resistance
• Dense fibre structure that limits light penetration
• Fabric thickness and texture that scatter radiation

These properties make hemp a strong candidate for sun protective clothing and hats.

Research Findings on Hemp & UPF Ratings

Influence of Weave Density

Weave density plays the biggest role in UPF. Even strong fibres like hemp can fail to protect if the weave is too loose.

• Dense weaves improve UV protection significantly
• Loose weaves allow UV rays to pass through
• Compact fibre spacing reduces UV transmission

A good test is holding the hat up to sunlight; less light passing through usually means better protection.

Impact of Colour & Dye Process

Colour matters because darker shades absorb more UV rays. Some dye processes can further enhance UV resistance, especially when the fabric becomes less transparent.

• Darker dyes generally improve UPF
• Natural dyes may increase UV absorption
• UV-treated fabrics may provide enhanced protection

This is why darker hemp hats are often better suited for strong UV conditions.

Reported UPF Range

Hemp fabrics can achieve UPF ratings from UPF 30 to UPF 50+, depending on thickness, weave tightness, and colour. Well-made hemp products may block up to 98% of UV rays, but this should not be assumed without testing.

For reliable safety, always check for:

• UPF certification labels
• Trusted brand testing information
• Quality weave and construction

Benefits of Hemp Hats for Hot Regions

UV Protection Potential

Hemp hats can offer strong UV protection when they are designed correctly. Protection depends less on the material name and more on construction quality.

A hemp hat performs best when:

• the brim is wide
• the weave is thick and dense
• the hat holds its shape consistently
• the fabric blocks light penetration

Skin-Friendly & Hypoallergenic Properties

Hemp is often considered suitable for sensitive skin because it is breathable and tends to reduce sweat irritation.

Benefits include:

• non-irritating texture for many users
• reduced likelihood of rashes
• less sweat buildup compared to synthetic hats
• hypoallergenic potential

This makes hemp hats a comfortable option for daily wear.

Limitations & Important Safety Considerations

Variation in UPF Performance

Not all hemp hats provide the same UV protection. Some are made for fashion rather than function, and may have loose weaves that allow UV rays through.

UPF can vary due to:

• brand quality differences
• weave looseness
• brim structure and thickness
• colour variation

For safety, UPF testing is highly recommended.

Hemp Hats Are Not Standalone Protection

A hemp hat alone cannot protect your entire body. Cancer Council recommends a layered strategy, meaning hats should support your sun protection in combination with sunscreen, clothing, and shade.

Hats are one part of protection, not the whole solution.

Essential Protective Pairings

For full SunSmart coverage, pair hemp hats with:

• SPF 50+ broad-spectrum sunscreen
• UPF-rated long sleeve clothing
• wraparound UV sunglasses
• shade use during peak UV hours

This combination provides the strongest reduction in overall UV exposure.

How to Choose the Right Hemp Hat for Sun Protection

Choosing a hemp hat for summer should go beyond appearance. The right design can significantly improve UV protection, comfort, and durability.

Brim Width

A brim is what creates the protective shade zone. Wider brims cover more of the face, ears, and neck.

• Choose a brim at least 6–7 cm wide
• Wider brims provide stronger all-day protection
• Avoid narrow brims if spending long hours outdoors

Fabric & Weave Quality

Hemp hats should feel structured and tightly made. A loose weave may look breathable but can reduce UV resistance.

You should look for:

• dense, compact fibre structure
• minimal visible gaps
• thicker construction for sun-blocking power

Colour & Treatment

Colour influences UV absorption and reflection. Darker shades tend to provide stronger UV blocking compared to light natural hemp.

• darker colours generally provide better protection
• UV-treated hemp hats may offer improved performance
• avoid thin, pale hats unless UPF certified

Fit, Stability & Comfort

Comfort matters because a hat only protects you if you actually wear it. A good hemp hat should stay stable during wind and movement.

Best features include:

• adjustable fit bands
• secure drawstrings or chin straps
• brim wires for shaping
• lightweight comfort without tight pressure

Combining Hemp Hats with Slip, Slop, Slap, Seek, Slide

Hemp hats naturally align with Cancer Council’s SunSmart framework. They reinforce the “Slap” principle while also supporting “Slip” when paired with hemp clothing or protective long sleeves.

A hemp hat helps build consistent habits by:

• making sun safety easy and wearable
• reducing direct exposure to facial skin
• encouraging daily outdoor protection routines
• complementing sunscreen and shade strategies

The best protection is the one you’ll actually use daily.

When Can You Use Hemp Hats This Summer?

Hemp hats are useful for far more than beach days. In Australia, everyday errands can involve dangerous UV exposure.

Hemp hats are ideal for:

• walking pets or commuting during peak UV
• shopping at open-air markets
• school drop-offs and playground supervision
• outdoor lunch breaks
• gardening and yard work
• farming, landscaping, and construction work
• beach walks and sunbathing (with sunscreen + shade)
• surfing breaks and coastal lounging
• outdoor yoga and fitness sessions
• cycling, running, and hiking
• cricket, tennis, and other team sports
• If you’re outside for more than a few minutes, it’s worth wearing one.

Conclusion: Hemp Hats as a Complementary SunSmart Solution

The use of hemp hats and hemp clothing is an intelligent choice when it comes to providing sun protection in harsh climates. This is especially true when these items are designed to ensure that they have large brims, thick weave, and sturdy build. These items support Cancer Council suggestions by providing physical barriers for the areas of the human body that are risky zones for sun-damage, such as the face and scalp areas.

However, the best approach is always a combination, as hats made from hemp are best combined with sunscreen, UV clothing, sunglasses, and shade. Used correctly, hemp is more than just a fashion statement; it’s part of a SunSmart lifestyle.
