How to Stay Active in the Heat—Even with Joint Pain

Staying active is one of the best ways to support joints, reduce stiffness, and maintain mobility. As temperatures rise in Southern California, joint pain or an autoimmune condition can make that harder. Let’s find out why and what you can do.

At Pacific Rheumatology Medical Center, our board-certified rheumatologist, Dr. Behnam Khaleghi, understands the challenges that warm weather presents when you have chronic joint pain.

In our Tustin and Laguna Hills, California, offices, Dr. Khaleghi and our talented team help patients with arthritis and other painful conditions to find ways to stay active even in the warmest months.

If you have rheumatoid arthritis or any condition that causes joint pain, here’s what to know as we head into summer.

Why heat can make joint pain worse

Heat affects the body in several ways, quickly increasing discomfort as the temperature rises. Dehydration is one of the biggest factors. When your body loses fluids, joints are less lubricated, and this can increase stiffness.

For people with inflammatory or autoimmune conditions, heat is a common trigger for flare-ups. You may experience more swelling, increased joint sensitivity, or a general symptom spike as the weather warms up.

Understanding these effects can help you plan your physical activity so you’re working with your body, not against it.

Making movement easier with joint pain

Making movement easier with joint pain can include a few different approaches, such as:

Choosing the right time of day to move

Timing your exercise can make a big difference in your comfort level. When it’s warm outside, early mornings (before full sunrise) and early evenings (around sunset) are usually the most comfortable times to exercise.

This timing limits your sun exposure while also reducing the risk of overheating.

Increasing hydration

Staying hydrated is essential for joint health, and it becomes more crucial than ever when it’s hot outside. Even mild dehydration can lead to faster fatigue and joint stiffness.

Keep a refillable water bottle nearby. Consider adding electrolytes (with powders or liquids) if you’re planning long periods of physical activity.

Staying hydrated throughout the day, not only while exercising, can keep your joints primed and ready for smooth performance.

Opting for joint-friendly movement

Low-impact activities are often the best choice when managing joint pain, especially in warm conditions. Walking is especially highly recommended for people with arthritis and other chronic joint conditions.

When you walk regularly, your knee joints go through a gentle cycle of pressure and release. This helps move fluid through the joint, delivering nutrients that keep the cartilage healthy and functioning properly. Walking can also trigger the release of endorphins that act as the body’s natural painkillers.

Some other good low-impact options may include cycling, stretching, and yoga. All can help maintain mobility without placing excessive stress on your joints.

Water-based activities may also be remarkably beneficial, and this time of year can be the perfect time to jump in. Swimming or water aerobics can simultaneously provide resistance and support.

It’s also important to recognize that some days will be more challenging than others. On flare days, gentle movement may be more appropriate than a full workout. Staying consistent over time is more important than pushing through discomfort and risking setbacks.

If heat consistently worsens your joint pain or makes it hard to stay active, it’s time to reach out for help. Call Pacific Rheumatology Medical Center at 714-266-1458 to book your appointment with Dr. Khaleghi today.
