Why your feet react differently during a night shift

1 July 2026

Anyone who regularly works night shifts in a hospital, nursing home or home-care setting will recognize the feeling immediately. By the early morning, your sneakers suddenly seem tighter, your heels feel heavier and every step along the hard corridors feels a little more sluggish than it does on a day shift.

But why does that happen? Why do your feet and legs respond differently at night, even if you may be taking roughly the same number of steps?

1. Your body clock and blood pressure

Your body follows a natural 24-hour rhythm. Normally, your body temperature and blood pressure drop during the night to encourage rest and recovery. But when you stay active, your vascular system has to work extra hard to pump blood from your feet back up toward your heart.

Because your blood vessels naturally relax a little more at night and circulation slows down, fluid can collect more easily in the lower limbs. This can lead to a tired, heavy feeling and mild swelling around the ankles and instep.

2. Metabolic waste builds up more quickly

Your metabolism is regulated differently during a night shift. Lymphatic drainage and the removal of lactic acid are slower when you stay awake at a time when your body is programmed for sleep. As a result, the small intrinsic muscles in the soles of your feet recover less quickly during short breaks, which can leave muscles and tendons feeling stiffer around five in the morning.

3. Changing movement patterns: rushing or standing still

A day shift often has a more continuous rhythm of walking and activity, while a night shift can be much less predictable. Periods of intensive walking may alternate with stretches of sitting still behind a computer for documentation and handovers.

That very alternation can be hard on your circulation. When you sit still, the active calf-muscle pump is missing, allowing fluid to accumulate. If you then suddenly have to rush to a room, cold and slightly swollen feet have to absorb peak loads straight away.

Practical tips to keep your feet feeling light until the morning handover

• Choose shoes with enough room in the forefoot: Because your feet expand during the night, you need a sneaker with flexibility and enough space around the instep and toes to prevent painful pressure points.

• Keep making small movements while sitting: Writing your reports? Circle your ankles and regularly pull your toes toward you to keep the calf-muscle pump active.

• Combine cushioning with good compression: A comfortable compression sock supports venous return and helps prevent fluid from building up, while a responsive sole absorbs the impact of hard floors. 

• Pay attention to hydration: Coffee helps keep you alert, but it can have a mild diuretic effect. Make sure you keep drinking enough water throughout your night shift to help keep your fluid balance and circulation in check.

Take good care of yourself

At night, you care for the people who need it most. Give your feet the support and comfort they deserve, so that even after handover you can still cycle or drive home comfortably.
