What Are Compression Garments? | How They Work & When To Use Them

They work by applying graduated pressure, strongest at the ankle and decreasing upward, pushing blood and fluid toward the heart. Whether managing a medical condition, recovering from surgery, or reducing post-workout soreness, these garments serve specific jobs they do well, and a few they don’t.

The Main Medical Uses For Compression Garments

Medical-grade garments treat conditions where blood or lymph fluid doesn’t move properly. Graduated compression stockings are standard for venous insufficiency, where leg veins struggle to return blood to the heart, and for lymphedema, where fluid builds up in tissues. Johns Hopkins Medicine notes that lower-body compression helps patients with orthostatic intolerance by moving blood back to the heart and brain. Post-surgical patients also wear them to reduce bruising, hematomas, and swelling. The mechanism is straightforward: external pressure counteracts forces that let fluid settle.

Do Compression Garments Actually Improve Athletic Performance?

The evidence is cautious. A 2022 systematic review found that performance-enhancing effects are small or trivial, and results are conflicting. What research does support is reduced muscle soreness and a perception of faster recovery after exercise. Many athletes feel they recover better, and that subjective benefit is real even if objective performance data is mixed. If you’re wearing them to run a faster mile tomorrow, the science says don’t count on it — but to feel less beat up the day after a hard workout, evidence lines up.

How To Wear Compression Garments Correctly

Getting fit and timing right matters. Medical sources recommend putting stockings on first thing in the morning when legs are least swollen. The standard method: turn the garment inside out to the ankle, insert your foot, and slowly roll it up, smoothing wrinkles. For thigh-highs or leggings, stand while pulling past the knees. A common mistake is wearing daytime garments overnight — unless a clinician prescribes it, that can restrict blood flow and worsen pain if the garment shifts during sleep.

• Compression socks/stockings — most common for circulation and swelling in legs
• Sleeves — worn on arms for lymphedema or post-surgery recovery
• Shorts/leggings — used by athletes and for abdominal or hip support
• Wraps and bandages — adjustable compression for variable swelling
• Inflatable devices — used in clinical settings for advanced lymph drainage

Garments that are too tight, slip down, or wrinkle won’t deliver proper pressure distribution. If you feel pain, numbness, discoloration, or worsening swelling, stop and consult a clinician — discomfort and fit issues are common but serious side effects are rare.

Who Benefits Most From Compression Wear?

People with diagnosed circulation issues — venous insufficiency, lymphedema, lipoedema, or post-surgical swelling — get the clearest benefit from graduated medical stockings. Athletes benefit mainly for recovery comfort rather than performance. For long flights or standing all day, light compression socks can prevent that heavy, tired feeling. The key differentiator is pressure distribution: medical-grade stockings have highest pressure at the ankle, while many over-the-counter options offer more uniform pressure that provides comfort but not the same therapeutic effect. Johns Hopkins emphasizes that abdominal compression may be necessary for conditions like orthostatic intolerance. Knowing what pressure level and style matches your situation makes the difference between a garment that helps and one that’s just tight underwear.
