Dog Days of Summer and Lymphedema: How to Stay Cool and Control Swelling

Summer is a wonderful time to enjoy vacations, backyard gatherings, gardening, and spending time outdoors. But for people living with lymphedema, the hottest days of the year can also bring increased swelling and discomfort.

If you’ve noticed that your compression garments feel tighter or that your affected limb feels heavier during hot weather, you’re not imagining it. Heat and humidity could make managing lymphedema more challenging. The good news is that with a few simple precautions, you can continue enjoying summer while protecting your lymphatic health.

Why Hot Weather Makes Lymphedema Worse

When temperatures rise, your body naturally tries to cool itself by widening (dilating) blood vessels near the skin’s surface. This allows more blood to circulate and release heat.

Unfortunately, this process also allows more fluid to leak from the tiny blood vessels into surrounding tissues.

For someone with a healthy lymphatic system, that extra fluid is usually collected and returned to circulation. However, when the lymphatic system is damaged or functioning poorly, excess fluid may not drain efficiently, leading to increased swelling.

High humidity might make matters worse because sweat evaporates less efficiently, making it harder for your body to cool itself. The longer your body stays warm, the greater the potential for additional swelling.

Should You Wear Compression Garments in Hot Weather?

One of the most common questions I hear is:

“Can I skip my compression garments when it’s hot outside?”

Although it may be tempting, the answer is generally no.

Compression garments for lymphedema remain one of the most effective tools for controlling swelling during the summer. In fact, they’re often even more important when temperatures rise.

If your garments feel unusually uncomfortable, it may be time to have them checked for proper fit or replaced if they’ve lost their compression. Some people also benefit from owning a second set, so they always have a clean, dry garment available. You might also consider lighter compression, like EdemaWear.

Summer Tips for Managing Lymphedema

Manage Heat Exposure

Whenever possible, avoid prolonged outdoor activity between 11:00 a.m. and 3:00 p.m., when temperatures and UV exposure are highest.

If you become overheated:

Move into air conditioning or shade.
Elevate the affected limb.
Apply a cool (not ice-cold) damp towel.
Drink water.
Rest until your body temperature returns to normal.

Avoid placing ice directly on the skin.

Stay Hydrated

Drinking plenty of water helps your body regulate its temperature and supports normal circulation. Dehydration makes your body work harder in the heat.

Choose Lightweight Clothing

Loose-fitting, breathable fabrics such as cotton or moisture-wicking athletic materials help keep your body cooler while reducing skin irritation.

Protect Your Skin

Healthy skin is your first defense against infection.

Apply sunscreen daily.
Avoid sunburn.
Moisturize dry skin regularly.
Treat cuts, scrapes, or insect bites promptly.
Watch for signs of infection such as redness, warmth, increasing swelling, pain, or fever, and contact your medical professional promptly if these occur.

Wear Compression Garments Consistently

Compression sleeves, stockings, and other compression garments help limit fluid buildup during hot weather.

To stay more comfortable:

Put on garments first thing in the morning, before swelling increases.
Wash garments according to manufacturer instructions.
Replace garments when they become stretched or lose compression.

Choosing Lymph-Friendly Activities

Swimming is one of the best forms of exercise for many people with lymphedema because the water provides gentle compression while allowing muscles to pump lymphatic fluid naturally.

After swimming:

Shower to remove chlorine or salt.
Dry your skin thoroughly, especially between fingers and toes.
Moisturize if your skin feels dry.
Put your compression garment back on once your skin is completely dry.

Walking, cycling, or other activities are often more comfortable in the early morning or evening. Pay attention to your body. If swelling increases or you begin feeling overheated, stop, cool down, elevate the affected limb, and rest.

Limit Excess Sodium and Alcohol

High-sodium foods may contribute to retaining fluid in some people.

Alcohol can contribute to dehydration, so enjoy it in moderation and drink extra water if you choose to have alcoholic beverages.

Prevent Insect Bites

Mosquitoes and other insects are more active during summer.

Because insect bites can irritate the skin and increase the risk of infection, use an EPA-approved insect repellent according to the product directions and wear protective clothing when practical.

Traveling with Lymphedema During Summer

Summer often means vacations and road trips. Whether you’re traveling by plane, train, or automobile:

Wear your prescribed compression garments.
Stay well hydrated.
Get up and move regularly during long trips.
Perform simple ankle pumps or hand exercises while seated.
Pack an extra compression garment in case one gets wet or damaged.

Planning can help prevent swelling before it starts.

Enjoy Summer While Protecting Your Lymphatic Health

Living with lymphedema doesn’t mean staying all summer indoors. Understanding how heat affects your lymphatic system allows you to make simple adjustments that help minimize swelling and reduce your risk of complications. By staying hydrated, protecting your skin, wearing properly fitted compression garments, and avoiding prolonged heat exposure, you can enjoy the season with greater comfort and confidence.

FAQ: Lymphedema and Hot Weather

Can heat make lymphedema worse?

Yes. Heat can increase swelling because blood vessels expand as your body tries to cool itself. When the lymphatic system cannot efficiently remove excess fluid, swelling may worsen. Many people notice their affected limb feels heavier, tighter, or more uncomfortable during hot, humid weather.

Should I wear compression garments in hot weather?

In most cases, yes. Compression garments remain one of the most important tools for managing lymphedema during summer. If your garment feels uncomfortable in the heat, check the fit, replace worn garments, or ask your lymphedema therapist about lighter fabrics or cooling options.

Is swimming good for lymphedema?

Yes. Swimming can be an excellent form of exercise because the water provides gentle compression while movement helps support lymphatic flow. After swimming, rinse and dry your skin thoroughly before putting your compression garment back on.

How can I reduce swelling during hot weather?

Helpful strategies include:

Wearing compression garments as prescribed
Staying hydrated
Avoiding prolonged heat exposure
Exercising during cooler parts of the day
Elevating the affected limb when swelling increases
Protecting your skin from sunburn, cuts, and insect bites

Can I exercise outside if I have lymphedema?

Yes, but timing matters. Choose cooler parts of the day, stay hydrated, wear lightweight clothing, and listen to your body. If you feel overheated or notice increased swelling, take a break and cool down.

Why is skin care especially important during summer?

Healthy skin helps protect against infection. Sunburn, insect bites, cuts, and dry or cracked skin can increase the risk of cellulitis, which may worsen lymphedema. Daily moisturizing and skin protection are important parts of lymphedema management.

Can I travel during the summer with lymphedema?

Absolutely. Travel is possible with a little planning. Wear your compression garments, drink plenty of water, move regularly during long trips, and pack an extra garment when possible.

When should I contact my healthcare provider?

Contact your healthcare provider or certified lymphedema therapist if you experience sudden swelling, increasing pain, redness, warmth, fever, or other signs of infection.

Managing lymphedema in the summer does not mean missing out on the season. By understanding how heat affects your body and making a few adjustments, you can enjoy warm-weather activities while protecting your lymphatic health.

Wishing you a healthy, safe, & enjoyable summer!

As I’ve gotten older, I’ve noticed I’m much less tolerant of hot, humid weather than I used to be. I’ve learned that listening to my body and slowing down when necessary helps me enjoy summer much more. I hope these tips help you do the same and have your best summer ever.

Hello,
Is there a compression stocking for the foot only? Only my left foot swells and I’ll be on vacation so don’t want a full stocking all the time.
thanks,
Sharon
