The car park routine: what to do when you are cold, tired and not at home

Every sensible post session recommendation assumes a warm bathroom and ten spare minutes. Here is the version for a February car park with numb hands.

MaterialsRoutine10 min
The short answer

The five minutes after a cold session decide most of what happens to your skin, and they are usually spent badly because you are cold and in a hurry. The order that matters is: rinse the salt off before anything touches you, peel kit rather than dragging it, blot rather than rub, get dry and covered quickly, and apply something to the lips, face and hands while the skin is still slightly damp. Everything else can wait until you are warm. The heavy application belongs at night, not here.

The situation, described accurately

You are standing next to a car in February. It is close to dark. Your hands do not work properly. There is sand in everything. The wind is coming off the sea and you are wearing a wet suit that you now have to get out of, in public, while cold.

Any routine that requires more than about four minutes, more than one hand, or any dexterity at all is not going to happen. Most published advice quietly assumes a warm bathroom, which is why most published advice is not followed.

What follows is ordered by how much difference each step makes per second spent, which is the only sensible way to order it.

One: rinse before anything touches you

This is the highest value action available and it takes ninety seconds.

Salt left on the skin is a water attracting film that keeps drawing after you leave, and salt crystals plus sand are abrasive particles sitting between your skin and everything that is about to be dragged over it.

Rinsing first means the towel, the clothes and the seat cover are not grinding grit across a softened layer. Cold fresh water is fine. It is not a shower and it does not need to be comfortable.

Get the face, the hands, the neck and, if you can bear it, the scalp. The scalp is the one everybody skips and it is the one that stays salty for hours.

Two: peel, do not drag

The skin under a suit has been held fully hydrated for one to three hours. It is softened, its bonds are strained, and it gives up cells with very little force.

Peeling kit off slowly, rolling it rather than pulling it over the skin, is the difference between removing a suit and sanding your shoulders. The same goes for boots, gloves and a hood, all of which are usually removed with more force than the suit because they are tighter.

The neck and the wrists are where dragging does the most damage, because those are the tightest points and are already the sites most likely to be marked.

Three: blot, do not rub

The towel arrives at the moment of maximum vulnerability, and a brisk rub removes cells that would have stayed put if you had pressed the towel against them instead.

This is the cheapest change in this entire publication and the one people resist most, because rubbing warms you up. It does warm you up. It also costs you a layer.

The resolution is to blot, then get covered, and warm up with clothing and a hot drink rather than with friction.

Ordering framework written by this publication from general skin physiology. It is not a measurement, it is not taken from any study, and no number in it is a reading.

Four: cover up before you stop moving

Standing about half dressed in wind, wet, is the worst combination in this publication: maximum evaporative gradient, a softened layer, and a mechanical load from clothing going on over damp skin.

Layers on quickly, hood or hat on, hands into gloves. The gloves matter more than people think, because warm hands stay flexible and flexible skin does not split.

Five: apply something, while damp, to three places

Do not attempt a full routine. Three sites, in this order of value.

Lips. The thinnest barrier on your body has just had salt and wind on it, and the drive home has a heater. An occlusive layer here does more per second than anything else you can do.

Hands. They are about to grip a cold steering wheel and they are the slowest site to recover.

Face. Particularly the leading edge, the cheekbones and the nose, which took the wind.

Applying while the skin is still slightly damp holds water in the layer rather than sealing a dry one. That is worth more than the choice of what you apply.

The drive home

Two things, both free.

Point the heater vents away from your face. Warm moving air on skin that has just come out of the sea is a wind exposure applied to a freshly softened layer, and people do it for forty minutes without noticing.

Do not plan a very hot shower at the other end. It is the most damaging avoidable event of the day, discussed properly in the article on showering. If you are cold, a warm one is fine; long and very hot is where the cost is.

And then the part that actually does the work

The car park routine is damage limitation. The recovery happens overnight, when nothing is being removed and there is nobody to look at you.

A generous application before bed, on damp skin, to the sites that are actually failing, is where the benefit accumulates. Everything in the car park exists to make sure there is less to recover from.

Common questions

If I only have two minutes, what should I do?

Rinse, then blot rather than rub, then put something on your lips. Those three cost almost nothing and prevent the abrasion, the drawing salt film and the drying on the drive home. Everything else can wait until you are warm.

Is a cold rinse at the beach better than a hot shower at home?

For the salt film, yes, because the cost of leaving it on is roughly proportional to the delay and the rinse takes ninety seconds. You can still shower at home. Keep it shorter and cooler than you want, because a long hot shower is the most damaging avoidable event of the day.

Why does it matter whether I rub or blot with a towel?

Because the layer has been held fully hydrated for hours and gives up cells with very little force. The towel arrives at the moment of maximum vulnerability, and rubbing removes cells that pressing would have left in place. It is the cheapest change available and the one people resist most, because rubbing warms you up.

Should I put a full routine on in the car park?

No. Three sites: lips, hands and face, applied while the skin is still slightly damp. The car park is damage limitation. The recovery happens overnight, when nothing is removing what you apply and there is nobody to look at you.

Does it matter which way the car heater is pointing?

More than people expect. Warm moving air on a face that has just come out of the sea is a wind exposure applied to a freshly softened layer, and a forty minute drive is often a longer exposure than the wind on the beach was. Point the vents at the glass rather than at you.
