Café Royal’s Akasha Holistic Wellbeing Centre

The Four Elements, 90 minutes, $300

This historic hotel uses water, fire, earth, and air to combat the main symptoms of jet lag: water retention, stiff muscles, dry skin, and sleep disruption. Think aquatherapy and hot-stone massage. There’s also a foot rub—and a scalp rub to stimulate the sleep-regulating pineal gland.
