Dozens of people to hit fully booked sauna on CHRISTMAS DAY

But in Norwich, exactly 42 people will be hitting The Lions’ Den, a riverside sauna at the Red Lion pub in Bishopgate, and braving a cold plunge while others are still in their pyjamas.

Four sauna sessions - at 9am, 9.45am, 10.30am and 11.15am - were up for grabs but have since been completely snatched up.
