Arthritis and sun exposure: Emma's tips for staying safe in the sun with psoriatic arthritis

As the temperature rises, you might be tempted to soak up some rays. But did you know that some arthritis medications can make you sensitive to the sun? This is sometimes called ‘photosensitivity’. 

What arthritis drugs make you sensitive to the sun (photosensitivity)? 

Some disease-modifying anti-rheumatic drugs (DMARDs), such as methotrexate and azathioprine, can make you more sensitive to the sun.

Usually, these drugs given to people who live with autoimmune conditions, such as rheumatoid arthritis, psoriatic arthritis and lupus. They help change the way a condition progresses, helping to relieve some symptoms. 

Some non-steroidal anti-inflammatory drugs (NSAIDs), such as naproxen, can also cause photosensitivity, as well as some antibiotics and antidepressants.  

For this reason, while we should all practise sun protection, it’s especially important if you have arthritis. 

If you haven’t already, why not check your medications to see if they cause photosensitivity?

Do I need to avoid the sun if I have arthritis?  

This isn’t to say that you should hide away from the sun altogether. A bit of sunshine is good for you as it provides Vitamin D, which is essential for healthy bones.  

But it’s worth being extra careful in the sun to keep yourself safe and protected.  

If you’re taking a medication that causes photosensitivity, it’s worth being extra cautious. Because, without the right precautions, it could lead to sunburn, skin rashes, heat stroke and other symptoms.  

Emma’s tips: How to protect yourself from the sun if you have arthritis 

Emma, 35, who has psoriatic arthritis, used to live in Australia and enjoys paddle-boarding in the summer. Here she shares how she manages her arthritis in warmer weather: 

When did you first realise that your medication could cause photosensitivity? 

I was very fortunate that my rheumatology nurse was extremely thorough regarding all the possible risks, symptoms, and side effects that my treatment could have. 

Due to having ultraviolet light therapy (UVB) for my psoriasis (ahead of moving on to medication), I already needed to be cautious about how much sunlight I should be getting. 

On top of this, I’m also on NSAIDs and selective serotonin reuptake inhibitors (SSRIs) which can also add to photosensitivity.

Has it encouraged you to practise sun protection more? Why is sun protection important? 

I’ve always prided myself on being pretty sun-savvy (especially as I spent a few years of my childhood living in Australia).  

But I’ve definitely become a lot more responsible and cautious since taking medication and knowing the risks around how they can react to sun exposure.  

My conditions can also make me feel worse the warmer it is, so I limit how much time I am out in the sun.

What do you wear to stay safe and protected in the sun? 

My top clothing go-tos are hats, sunglasses, and a light kimono or shawl that is breathable but also provides just enough protection.  

Because my skin is quite sensitive, and my temperature can fluctuate a lot, I try to wear fabrics such as cotton and linen as they’re lighter and softer.  

If I’m on the beach, swimming or paddleboarding, I make sure to wear a rash vest too.

What other tips would you give to someone with arthritis who wants to stay safe and protected in the sun? 

My top tips are: 

• Wear sunscreen that is at least SPF 30 (or higher if you can). This should be a daily thing and when you’re out more make sure you’re topping up regularly.  
• Wear lighter, brighter colours and materials. You don’t have to completely cover up. But avoid having your skin in the sun for too long. 
• Stay hydrated! Drink plenty of water or fruity drinks. Of course, you can still enjoy alcohol and caffeine, but know your limits and be sensible. They will dehydrate you, are more likely to cause other symptoms such as headaches and may also react badly to your medication.  
• Wear hats and sunglasses to protect the top of your head and your eyes. 
• Avoid staying out in peak sun hours. This is said to be between 10am-4pm but it depends on the time of year. This isn’t to say you can’t go out, just make sure you’re not in the direct sun the whole time. 
• Find shaded places as much as possible to keep covered. 
• Avoid additional tanning (e.g sunbeds). 
• Carry a medical alert card in case of emergencies and inform people you are with where to find out more information should they need to. 
• Most of all, have fun, but keep yourself safe!

What would you say to someone who is worried about spending time in the sun because their medication causes photosensitivity? 

There’s no need to hide away or not enjoy the warmer days. Everyone’s bodies react differently to the heat as well.  

As much as I’d love to spend a lot of time in the sun, I find it actually makes me feel worse a lot of the time as it causes migraines and more swelling in my joints.  

Find what works best for you and stay informed on the medication you use and the effects it can have. 

If I had to stress the two most important tips it would be hydration and suncream! Sun safety is incredibly important, but you can still have a great time practising it.
