Why long shifts are hard on legs

MedlinePlus explains that valves in the leg veins keep blood moving toward the heart, and when those veins are under strain, blood pools in the legs, especially while standing. Long periods on your feet, with few chances to sit and raise your legs, are exactly the conditions that bring on heavy, aching legs and puffy ankles by the end of a shift.

Sigvaris names nurses, teachers and hair stylists among the workers it designs everyday compression for, and says graduated compression supports the proper function of the venous valves. MedlinePlus lists easing aching or heavy legs and reducing swelling as the main reasons stockings are used.

Choosing the pressure

Sigvaris's level guide maps neatly onto shift work:

Firmer is not automatically better. A sock you peel off at the break because it pinches gives you nothing for the rest of the shift.

Fit details that matter on a long shift

• Measure, do not guess. Sigvaris says to measure the ankle at its narrowest point and the calf at its widest, plus calf length from the floor to the bend of the knee while seated. Measure soon after waking.
• Top band placement. MedlinePlus says a knee-length stocking should sit about 2 fingers below the knee bend. A band that rides into the back of the knee will dig in when you squat or kneel.
• No bunching. Smooth out wrinkles at the ankle and instep. Creases become pressure lines over hours of walking.
• Calf size. If your calf measures large for your ankle, look at wide calf compression socks rather than sizing up.

Fabric and comfort for work

Shift socks get worn hard and washed often. Look for moisture-wicking synthetic blends or merino wool for sweaty shoes, a cushioned sole if you are on hard floors, and a flat toe seam. Darker colors hide scuffs; many hospitals are fine with patterned socks under scrubs, but check your dress code.

MedlinePlus advises washing stockings daily in mild soap and water, rinsing, and air drying, and keeping 2 pairs so one is always clean. For a weekly rotation of shifts, more pairs make that easier. It also says to replace them every 3 to 6 months, since the fabric loses compression over time.

A simple pre-shift routine

1. Put socks on in the morning before legs swell, as MedlinePlus advises, ideally before you leave home.
2. Roll the sock to the heel, place your heel, then unroll it up the leg.
3. If they are hard to pull on, MedlinePlus suggests letting lotion dry first, a little powder, or rubber dishwashing gloves for grip.
4. On breaks, walk a little or raise your legs if you can.
5. Take them off at bedtime. For why, see can you sleep in compression socks.

When compression is not the right fix

Healthcare workers often know the red flags but ignore them in themselves. Swelling in only one leg, a warm or red calf, or new chest pain or breathlessness needs medical care, not a firmer sock. If you have diabetes, numbness in your feet, or cold, pale feet, ask a doctor before using compression, since squeezing a leg with poor arterial flow can do harm.

What to look for when you buy

Questions people ask

What mmHg compression socks are best for nurses?

Most nurses start with 15 to 20 mmHg, which Sigvaris lists for achy or heavy legs and busy days. 20 to 30 mmHg is usually chosen with a doctor for vein problems.

Should nurses wear compression socks every shift?

Many wear them on every shift that involves long standing. They work best put on before legs swell.

Are compression socks good for standing all day?

Sigvaris designs everyday compression for people who stand or sit at work, and MedlinePlus says compression helps reduce leg swelling and heaviness.

How often should nurses replace compression socks?

MedlinePlus says to replace stockings every 3 to 6 months to keep their support.

Can compression socks cause problems?

Wrong size, bunching or wearing them with artery disease or numb feet can cause harm. Measure properly and ask a doctor if you have those conditions.
