What Ten Minutes With Your Legs Up Actually Does
It is old advice, which usually means it survived for a reason. The reason here is straightforward plumbing.

Put your feet up is the sort of advice that sounds like a figure of speech. It is not. It describes a specific mechanical intervention, and the detail that matters is the height.
The problem it addresses
Across a day of standing, fluid accumulates in the lower legs. Blood has to travel back up against gravity, the calf muscles that normally pump it are holding still rather than cycling, and a portion of the fluid moving out of the small vessels into the surrounding tissue simply stays there.
That accumulation is what makes legs feel heavy, what makes socks leave marks, and what makes shoes feel tighter at seven than they did at seven in the morning.
Why height is the whole point
Lying flat helps a little. Raising the legs above the level of the heart helps considerably more, because at that point gravity stops working against the return and starts working with it.
That is the entire mechanism, and it is why the specific instruction is above the heart rather than simply up. Feet on a coffee table is barely elevation. Feet on the arm of the sofa whilst lying down, legs up against a wall, or a couple of pillows under the ankles in bed all clear the threshold.
Ten minutes at the right height beats an hour at the wrong one.
How long, and when
Ten to fifteen minutes is enough to make a noticeable difference. Longer is fine and is not proportionally better.
Timing matters more than duration. Doing it before bed rather than after means you spend the night with legs that have already drained rather than legs that spend the first part of the night draining.
And doing it at the end of a shift rather than saving it for the weekend addresses the accumulation before it compounds across consecutive days.
What to combine it with
Two minutes of walking beforehand cycles the calf pump and moves things along before gravity takes over.
A few ankle circles or heel raises whilst elevated keeps the muscles working in the helpful direction.
None of this is complicated, and none of it requires anything you do not already own.
When swelling is not just a long day
Ordinary work related swelling affects both legs, builds through the day, and has resolved by morning.
Swelling in one leg only, swelling that does not settle overnight, or swelling with pain, warmth or redness in the calf is a different situation and warrants prompt medical attention rather than elevation.
Persistent swelling in both legs that is new, or that comes with breathlessness, is also a reason to see a GP rather than to adjust your evening routine.
