Lymphedema Physical Therapy: Beat the Heat This Summer

Medically reviewed by Misty Seidenburg

When summer hits with full force, the sweltering heat and sticky humidity aren’t just uncomfortable. They can also intensify lymphedema symptoms. For individuals managing lymphedema in the legs or arms, warm weather can worsen swelling and discomfort, mainly due to the body’s natural response to heat. Fortunately, you can take steps to minimize the effects of summer on your lymphatic system. From hydration and skincare to lymphedema physical therapy, this guide provides practical strategies for relief as temperatures rise.

Lymphedema and Summer Heat: Understanding the Impact

Lymphedema is a chronic condition characterized by the accumulation of lymphatic fluid, typically in the limbs, resulting from impaired lymphatic drainage. It can result from cancer treatment, surgery, trauma, or congenital issues. A common misconception is that hot weather directly causes lymphedema. In reality, it tends to aggravate existing symptoms.

 Here’s why summer can be a challenge:

• Humidity slows sweat evaporation, trapping body heat.
• Heat causes blood vessels to expand, making fluid leakage and swelling more likely.
• Heat edema, which is temporary swelling due to heat, can further complicate symptoms for those already managing lymphedema.

While you can’t control the weather, you can control how you respond.  Here are some simple and effective ways to combat lymphedema symptoms this summer.

Important Note: The following tips are for informational purposes only and are not a replacement for professional medical advice. Always consult your healthcare provider before making any changes to your lymphedema management plan.

Hydration: Your First Line of Defense

One of the simplest yet most effective tools in your summer care arsenal? Water.

Dehydration can thicken lymph fluid and slow drainage, making symptoms worse. On the other hand, staying hydrated helps regulate body temperature and keeps your lymphatic system functioning more efficiently.

 Tips to stay cool and hydrated:

• Aim for at least half your body weight in ounces of water daily, more if you’re active or outdoors. Up to 20% of daily intake can come from food
• Add fruit slices or herbs (like mint) to make hydration more appealing.
• Keep a water bottle nearby and sip frequently rather than waiting to feel thirsty.

Did you know? Thirst is actually a late indicator of dehydration, so drinking consistently throughout the day is key. By the time you feel thirsty, your body may already be running low on fluids. Building hydration into your morning, midday, and evening routine can help prevent swelling and support overall lymphatic health.

Dress Smarter, Not Warmer

What you wear affects your body’s ability to regulate heat and manage fluid retention. Clothing choices not only affect comfort but also play a direct role in preventing overheating and skin irritation, which can worsen lymphedema symptoms.

 Do:

• Wear loose-fitting clothes that don’t restrict circulation.
• Choose light, breathable fabrics like cotton or moisture-wicking synthetics.
• Protect your skin from sunburn, which can increase inflammation.

Avoid:

• Tight or heavy garments, especially around swollen areas.
• Dark colors that absorb heat.
• Materials that trap moisture, like some synthetics.

A little preparation goes a long way in managing lymphedema during summer. Planning your wardrobe with comfort and safety in mind can help you stay cool, confident, and more in control of your condition.

Compression Therapy in the Heat: What You Need to Know

Wearing compression gear during the summer can be uncomfortable, but it remains vital to effective lymphedema treatment. Compression helps guide lymphatic fluid through the body, reducing the risk of fluid buildup and swelling.

To make summer wear more manageable, it’s best to put on garments early in the day when swelling is minimal. Selecting lighter, breathable materials designed for warm weather can increase comfort. Also, maintaining clean, dry skin underneath helps prevent irritation. If you’re unsure about fit or fabric, a certified lymphedema therapist can help you find the right option.

Practicing Skin Protection and Lymphedema Self-Care

Hot weather means more risk of sunburns, insect bites, and skin infections, all of which can trigger a lymphedema flare-up. Lymphedema self-care involves staying proactive and protective.

Daily essentials:

• Moisturize with a gentle, unscented lotion to prevent dryness and cracking.
• Use broad-spectrum sunscreen (SPF 30 or higher) and reapply every 2 hours.
• Wear insect repellent when outdoors to prevent bites.
• Clean cuts or scrapes immediately and monitor for signs of infection.

Consistent skincare is a key part of managing symptoms and avoiding complications. By incorporating protection into your daily routine, you can help prevent flare-ups, stay ahead of potential infections, and enjoy greater peace of mind throughout the summer season.

Movement Matters: How Physical and Occupational Therapy Can Help

Heat may slow you down, but movement is essential for managing lymphedema. That’s where lymphedema therapy comes in. Lymphedema therapy combines therapeutic exercises, manual lymphatic drainage techniques, and other manual therapies with compression therapies to encourage lymph flow and alleviate pressure and pain.

 How physical and occupational therapy for lymphedema helps:

• Promotes lymph drainage through guided movement.
• Reduces discomfort and heaviness.
• Enhances mobility and strength over time.

Physical and occupational therapists also provide education and support to help patients prevent and manage lymphedema symptoms outside of the clinic.

Signs You Should See a Healthcare Provider

Most summer-related lymphedema symptoms can be managed through self-care; however, the tips above may not be suitable for every individual. Always discuss your concerns with your healthcare provider.

Additionally, sudden changes in swelling, skin that feels hot or tender, fever, or difficulty moving a limb may indicate an infection or other complications. Early attention can help prevent symptoms from worsening and support your overall progress. If you have these symptoms, seek prompt medical attention.

Simple Daily Practices for Summer Relief

Here’s a quick list of strategies to keep symptoms in check before they become a problem.

1. Hydrate consistently, don’t wait until you’re thirsty.
2. Elevate your legs or arms to encourage fluid return toward the heart, helping reduce swelling and improve circulation.
3. Use cold packs on the back of your neck or forehead to cool your entire body.
4. Schedule outdoor activities in the early morning or evening.
5. Track your symptoms in a journal to notice patterns or triggers.

Pairing these strategies with expert lymphedema therapy and proper compression support can help keep swelling under control throughout the summer.
