For people managing chronic pain, the changing of seasons isn't just a background detail – it can significantly affect how much pain they experience day to day. Summer, with its heat, humidity, and disrupted routines, can be a complicated time. But it's also a season that offers some things that are genuinely useful: more daylight, opportunities for gentle outdoor movement, fresh anti-inflammatory produce, and a pace that can, for some people, feel more manageable than the pressure of winter.
Understanding both sides of the summer equation can help you navigate the season more comfortably.
Heat and Pain: A Complex Relationship
Heat affects different pain conditions differently – which is why some people swear summer helps their pain while others find it significantly worse.
For joint conditions like osteoarthritis and rheumatoid arthritis, many people find that warmth eases stiffness and improves joint mobility. The lack of cold and damp that can aggravate joints, and the general warmth of the season, may be genuinely beneficial. Gentle movement in a warm environment – an outdoor walk or a heated pool – may feel more accessible than in colder months.
For inflammatory conditions and flares, high heat and humidity can sometimes trigger or worsen inflammation. Staying cool, avoiding direct sun during the hottest hours, and using cold therapy (cool packs, cold water immersion) during flares may help manage this.
For fibromyalgia and conditions involving nervous system sensitisation, very high heat can increase overall sensory overwhelm and fatigue, while milder warmth may feel soothing. Paying attention to your own pattern – and not pushing through heat-related increases in symptoms – is important.
For headaches and migraines, heat, dehydration, and disrupted sleep (from warm nights) are all known triggers. Managing these proactively in summer is important for anyone who experiences heat-related headache patterns.
Hydration: Critical for Pain Management
Dehydration is one of the most overlooked contributors to pain, and summer significantly increases the risk. Even mild dehydration can worsen headaches, muscle cramps, joint stiffness, and overall pain sensitivity – because the body's tissues, including cartilage and discs, require adequate fluid to function properly.
In summer, fluid needs increase significantly – particularly with activity, heat, and air conditioning (which dries the air). Practical steps include: keeping a large water bottle visible and accessible throughout the day, eating foods with high water content (cucumber, watermelon, strawberries, courgette, lettuce), and being mindful that alcohol and caffeine increase fluid loss.
Coconut water, electrolyte drinks, or simply adding a pinch of good salt to water can help replace electrolytes lost through sweating – electrolyte balance matters for nerve and muscle function, both directly relevant to pain.
Summer Foods That May Help
Summer is a season of genuinely anti-inflammatory produce – which means it's one of the better times of year to eat in a way that may support pain management:
- Berries – strawberries, blueberries, raspberries, and cherries are all high in anthocyanins, antioxidants with anti-inflammatory properties. Tart cherries in particular have been studied for their effect on gout and muscle soreness
- Cucumber and watermelon – high water content supports hydration; watermelon also contains lycopene, an anti-inflammatory antioxidant
- Oily fish at the barbecue – salmon, sardines, and mackerel on the grill provide omega-3 fatty acids with anti-inflammatory effects
- Fresh herbs – basil, rosemary, and mint are naturally anti-inflammatory and easy to use abundantly in summer cooking
- Cold-pressed extra virgin olive oil – used generously in summer salads and on grilled vegetables
- Tomatoes – rich in lycopene, particularly when cooked or served with olive oil
Movement in Summer
Summer often offers more opportunity for the gentle outdoor movement that benefits pain – but it's important to manage the heat. Early morning and evening are cooler and can make movement more accessible. Swimming is one of the best forms of exercise for pain, and open-water swimming in particular has a growing body of anecdotal and emerging clinical support for its effects on chronic pain and mood.
For people whose pain limits outdoor activity, even sitting in a garden, a gentle walk in the early morning, or movement in a cool, shaded space can provide benefit. The psychological lift of being in natural light and green space also matters – light exposure supports vitamin D synthesis, mood regulation, and better sleep, all of which influence pain.
Vitamin D
Vitamin D deficiency is associated with increased pain sensitivity and musculoskeletal pain. Summer is the time when the body can synthesise vitamin D through sunscreen-free sun exposure (around 15–20 minutes of midday sun on arms and legs, without burning). This is one of summer's genuine gifts for people in pain – though supplementation may still be needed, particularly for those who spend limited time outdoors.
Sleep in Summer
Warm nights can significantly disrupt sleep, and poor sleep worsens pain. Keeping the bedroom as cool as possible – a fan, open windows at night, cooling bedding – and a cool shower before bed can help. If you use heat as a pain management tool, adjusting to lighter, cooler heat applications in summer (rather than a hot water bottle at full temperature) may preserve the benefit while reducing disruption to sleep.
Peppermint for Summer Pain
Peppermint oil – either applied topically (diluted in a carrier oil) or used aromatically – provides a natural cooling sensation that many people find relieving in summer heat. Its menthol content acts on cold receptors in the skin, creating a pleasant contrast to the heat and potentially reducing pain signalling in the affected area. It's a particular favourite for tension headaches, muscle aches, and joint discomfort.
