So… you’ve fallen in love with open water swimming and you can’t bear the fact that the season will end and you want to swim right throughout the winter? Or are you are one of the growing number of competitive swimmers and triathletes that want to push your boundaries in freezing cold conditions outside of the traditionally accepted temperature parameters of your sport?

Are you wondering how you will be able to swim through very cold conditions and still come out smiling and safe?

The Challenges of Swimming in Cold Water

Swimming in cold water presents you with a lot of challenges as your body struggles with the stress imposed by a hostile environment. Depending on the actual temperature (see our swimming temperature scale at the bottom of this article), you can expect to experience the following temporary conditions:

  • Coldwater shock – the involuntary, sharp intakes of breath experienced when first getting in – dangerous if you are immersed at the time.
  • Excruciating “ice-cream head” pain when first putting your head in the water as the cold-sensitive nerves in the face and palate go into shock.
  • Feeling a tightness in the chest and experiencing a shortness of breath.
  • Accentuated dizziness when getting out of the water following a swim.
  • Temperature “after drop” some minutes after a very cold swim which brings the onset of deep shivering. The effect of cooled peripheral blood returning to the core and/or the warm core rewarming the periphery.

This is not intended to scare you off, far from it; to be forewarned is to be forearmed. These are all part of the winter swimming experience and last for a brief period of time relative to the wonderful experience of cold water swimming and the positive effects it has on your mood and enjoyment of swimming.

After a lifetime of swimming in the Lake District, and many seasons of guiding and coaching clients with a wide range of experience and abilities, these are our top tips for swimming in cold water and actually enjoying it:

Good company

I like to swim on my own in most situations but when I’m cold water swimming I always make sure I’m in good company, and by that I mean people who could actually get into the water and help me if I got into trouble, if they are not in with me already. It’s great to have someone else to help you pull your jacket on and zip you up when you are having a bit of a shiver post-swim.Happy Cold Water Swimmers

Ice swimming is a head game, as you are about to find out, and the support of other swimmers or club members is great for your safe enjoyment of the swim and for your motivation in general (particularly if you are meeting at the crack of dawn for a quick dip in the lake before work!).

If you are looking for friendly winter swimming companions in the Lake District, try asking in our social Facebook group “Lake District Open Water Swimmers” and you will usually get a positive response and someone to swim with.

Get Organised

Warm-Up. If you hit the water when you are already warm the experience is going to be a whole lot more enjoyable. Have a bit of a trot around the lakeshore, or jump up and down for 10 minutes before your swim and you’ll not only generate heat, you will better prepare your body to deal with the shock of the cold water and exercise to follow.

Get your Kit together. You can tell experienced ice swimmers by how well they set up their kit on the shore before their swim. After a cold swim, you won’t be in the mood for fiddling with zips or buckles to open your bag or to dig to the bottom of your rucksack for that fluffy changing robe. So have it all ready and to hand (or at least at the top of your bag) before you get in to prevent faffing when you really need to be getting some warm dry kit on fast, before the shivers set in.

Suit Up – What gear do you need? Now there are two camps here: Wetsuits and Skins. If you are wondering if Lianne and Boot swim in the coldsomeone you are about to swim with only ever swims without a wetsuit (skins), don’t worry, they will tell you all about it within 60 seconds of meeting you! Swimming without a wetsuit in winter water is not for everyone and may not even be relevant to you if you are preparing for events that stipulate wearing wetsuits, but it is an experience that must be tried at least once in your lifetime and one that will certainly be more enjoyable than you may think. Many swimmers choose to extend their enjoyment of an icy skins dip with some or all of the winter swimming accessories we mention here. (we discuss the specifics of gear in further articles – Cold Water Swimming Accessories, and Wetsuits for Cold Water Swimming)

Now is a good time to mention the dangers of peer pressure – Don’t let others push you into a ‘skins’ swim when you don’t want to, or if you are not ready for it… wear what you want to swim in! Die-hard winter swimmers are usually very acclimatized or have their own suit of bioprene to keep them warm (or a combination of both). Do your own thing and make sure you enjoy it.

  • A small Thermometer. Get to know how you react to gradually descending temperatures and how long you can safely remain in the water. These can be an important piece of safety equipment.

Get your head in gear

Yes it’s going to be a shock and yes it’s going to be bloody freezing at first, but don’t keep telling yourself that! Think warm thoughts and focus on how great you’ll feel when you get over the initial cold water shock and how annoyingly cheerful you’ll be over the next 24 hours when you’ve had your triple shot of endorphins…

Getting in – Take your time but keep it moving. Don’t faff or dither about when getting in. Get the cold water shock response out of the way by gradually wading in, wetting your face and neck as you go. This is the only acceptable time when wild swimming to let a few choice swear words slip!

Everyone has their own little routine when getting in but personally I prefer to wade slowly in and get my head downLianne is Cold and swim steadily off as soon as possible, concentrating on calm breathing, smooth strokes and sucking up the pain from the head freeze. If the cold gets a bit much I’ll slip into a bit of breaststroke until my body balances out a little and I can begin to really enjoy the experience.

Remember that your body is coping with a lot and is busy dealing with the physiological stress of cold water that is slowly leading you down the hypothermia path. Blood pressure and heart and respiration rate are ramped up already, so if you go off at your fastest mile pace you will come up short in a few yards, fighting for your breath and thinking you are having a heart attack. So, steady away until you are well into your groove.

Getting Out

When it’s time to get out, when it stops being fun and before you start shivering, get back into go-slow mode. Make like a seal and swim as far into the shore as you can and sit/kneel up slowly to reduce the inevitable head spin. When you are ready slowly get up and out, step into your Crocs, slip into your Dryrobe and begin getting changed right now!

Warm up after Cold Water SwimmingThe colder the water and the longer you have been in, the more you will experience an after-drop of your core temperature (the effect of cooled peripheral blood returning to the core and/or the warm core rewarming the periphery) – this brings on deep shivering which is actually a positive response of the body to mild hypothermia. This is a good thing as it means that your body is reacting naturally to warm you up, but it makes putting your undies on a whole lot more difficult… So get some good warm outdoor clothes on before the after drop really kicks in. Now is a good time to get some warm drink and food down you to help fuel the inner fire too. Eating and drinking are a great way to generate heat as any mountaineer will tell you, and is often an important part of the fun social scene that always seems to accompany cold water swimmers (love ‘em!).

A Last Note on Acclimatisation

Last winter I was unable to continue swimming into the winter for the first time in years. I went off to swim with a mate in February and felt terrible – In my de-acclimatized state, I just couldn’t function like I was used to. It was a good insight into how “normal swimmers” feel when we go down to the lake in the winter, extolling the virtues of ice swimming and telling them how much fun we’ll have (apologies to you all!), and how well adapted we can actually become with regular cold water swimming.

The good news is that with regular cold water swimming (a few times a fortnight), you will eventually become very adapted to swimming in these conditions depending on individual physiology. The acclimatized swimmer still feels the initial pain of getting in but is more able to deal with the shock associated with it. The most pleasant way to do this is to just continue swimming into the autumn and then through the winter. It doesn’t take much to remain acclimatized – I think once a week is just about the minimum and it gives you a huge advantage in cold water.

For the winter tarn dipper this means more fun and enjoyment and for the hard-core triathlete or ice-swimmer, increased performance and an edge over the competition.

I hope you find these tips useful and get as much out of your winter swimming as I do. Remember to let common sense always be your guide and to swim for the sheer love of it.

Come on in, the water’s lovely…!
