Switzerland Jet Lag Calculator

London departures face 1 hours, New York 6, Tokyo 8 and Sydney 9 — each figure feeds the recovery estimate for Bern at UTC+1. The size of your Switzerland jet lag is the absolute gap between your home offset and Bern's UTC+1.

Under six hours of shift, most travellers absorb Switzerland inside a long weekend — eastward nights feel short for two or three evenings in Bern (UTC+1), then settle. Reference frame for Switzerland: Bern keeps UTC+1 and sits 540 m above sea level in Western Europe, with daylight saving nudging summer clocks an hour.

Direction changes the bill: flying to Switzerland eastward from London costs about 1 days of recovery. The westward routing to Bern costs only 0.7 — the body clock delays to Switzerland more easily than it advances. Three levers run the Switzerland recovery: light, sleep timing and hydration.

Start with pre-flight drift for Switzerland — 30–60 minutes per day toward Bern time. Hold the line in the air for Switzerland: water instead of wine. Caffeine before noon only, and set the watch to Bern time, UTC+1.

Day one in Bern: sunlight before midday. Meals go on the local clock in Switzerland, and lights-out stays no earlier than 9:30pm so the body accepts the new zone. Applied to this Western Europe trip: 1 hours east from London to Bern maps to about 1 reset days, so a Switzerland itinerary should front-load outdoor time on days one to 1.

Near-4am wakings are part of night one in Bern (540 m, UTC+1); stay dark and still, skip the clock-checking, and Switzerland nights settle by the third. Cap naps at 20–30 minutes and finish them by 3pm Bern time (UTC+1); anything longer steals the night that actually resets your clock to Switzerland. For shifts over six hours — into Switzerland, that means the 1-hour London gap — 0.5–3 mg of melatonin at Bern bedtime (UTC+1) pulls the clock faster in 3–4 nights.

Clear Switzerland dosing with a clinician first. Practical baseline: lights out in a dark 16–20°C Bern room (540 m, UTC+1), and no evening alcohol for the first two nights while the Switzerland clock settles.
