Cold Shower Challenge

A gasping person stands under a rushing icy shower, arms braced and eyes wide with a determined grin, frost and cold-blue mist swirling around, glowing ice-crystal accents. Dramatic cold blue lighting. Huge text 'COLD SHOWER CHALLENGE' in white with a cyan outline across the top, a green up-arrow on a 'willpower' meter and a snowflake icon. Water droplets frozen mid-splash. Intense, invigorating, high-contrast challenge energy.

一个人倒吸凉气地站在急冲的冰冷淋浴下，双臂紧撑、双眼圆睁却带着坚定的笑，四周冷蓝雾气与霜花打旋，点缀着发光的冰晶。戏剧化的冷蓝打光。顶部是巨大标题「冷水澡挑战」，白字配青色描边，一支绿色上箭头位于「意志力」量表上，配一个雪花图标。飞溅的水珠凝固在半空。强烈、提神，强对比的挑战氛围。
