First Dip
Prepare properly before your first cold swim
A changing robe or DryRobe for after, neoprene gloves and socks in winter, and a swimming partner who knows where you'll be. Never cold-water swim alone, especially in the first year.
Enter water below 15°C for the first time
The cold shock response — gasping, racing heart — is involuntary and fades in 60–90 seconds. Enter slowly, breathe deliberately, and don't plunge head-first. Stay until the gasp reflex has settled.
Complete a 2-minute immersion
Two minutes is enough to trigger cold adaptation responses and test your physiological and psychological reaction to sustained cold. For most beginners this is the first real benchmark.
