Couple walking outdoors in summer Warm weather is a relief for many, but for people living with osteoarthritis the change of season brings its own set of joint challenges. Heat, extra activity and dehydration all play a part in how comfortable your knees, hips and hands feel through the warmer months. Here's what actually changes in summer, and the simple steps that help you stay active and comfortable.

1. Dehydration and Joint Stiffness

As temperatures climb, your body loses more fluid through sweat. When you are even mildly dehydrated, the body makes less of the synovial fluid that keeps joints gliding smoothly, which can leave them feeling stiff and tender by the afternoon.

Aim for steady hydration across the day rather than a few big glasses at once, and lean on water-rich foods like cucumber, melon and citrus. Easing back on coffee and alcohol in the heat helps too, since both pull extra fluid from the body.

2. Increased Activity Levels and Overexertion

Longer days invite more gardening, walking and weekend outings. Movement is good for joints, but a sudden jump in activity can overload weight-bearing joints like the knees and hips and leave them inflamed.

Favour low-impact options such as swimming, cycling or gentle yoga, and build up gradually. A light brace or compression sleeve can take pressure off a sore joint, and short rest breaks keep a good day from turning into a flare-up.

3. Heat-Induced Swelling and Fatigue

High temperatures widen blood vessels, which can lead to mild swelling and a feeling of heaviness in the joints. The heat also saps energy, making it harder to keep up your usual movement.

A cool shower, a chilled pack or simply resting with your legs raised can settle swelling quickly. Keep activity to shorter, more frequent sessions during the hottest part of the day, and stay in the shade when you can.

4. Managing Inflammation and Supporting Joint Health

The Problem:

For many people, low-grade inflammation is the constant background to osteoarthritis, and summer heat can turn the volume up. Reaching for oral pain relief every single day isn't ideal, and long-term use carries its own trade-offs.

The Solution:

A targeted topical can take the edge off without the systemic load. Outfield Organics Deep Sea Magnesium & MSM True Joint Cream pairs magnesium chloride and MSM (DMSO₂) with arnica, boswellia and chamomile, using menthol as a penetration enhancer so the actives absorb where you need them. It is trusted by 168,000+ customers, holds a 4.7-star rating across 1,491+ reviews, and is backed by a 90-day money-back guarantee.

Conclusion

Summer doesn't have to mean sore joints. Staying hydrated, pacing your activity, cooling down when swelling creeps in, and supporting your joints with the right topical all add up to easier, more comfortable days. With a few small adjustments you can enjoy the season and keep moving.

Frequently Asked Questions

Does it really work?

The mineral deficiency driving OA deterioration is credibly documented across peer-reviewed research. 

 

A 2023 systematic review in Rheumatology International confirmed across 17 clinical trials that transdermal mineral therapy measurably reduces joint pain and improves mobility. 14 days minimum to begin feeling the difference. 90 days for full results.

Can I use it alongside my current medication?

Yes. If you're still using NSAIDs, taper slowly rather than stopping cold turkey. The cream works alongside whatever you're currently doing.

 

Most customers find their painkiller use reduces naturally over the first few weeks.

Is it safe for sensitive skin?

Yes. No synthetic fragrances, no parabens, no steroids, no harsh chemicals. Suitable for daily use on all skin types.

How do I use it? How many times a day?

We advise customers to use it once in the morning, and once at night before bed.

 

Ideally, use after a warm shower when your pores have been opened up.

You may also use it for topical relief throughout the day.

What if I don't like it?
