Wellness fads are getting more extreme, from cryotherapy to IV drips. Cryotherapy, a treatment that involves enduring a -292-degree environment, is predicted to grow from $2.5 billion in 2016 to $5.6 billion globally by 2024 according to Grand View Research. IV tubing is expected to reach $1.2 billion by 2025, while compression therapy and hyperbaric oxygen chambers are also trending. Why? It could correlate with the increased popularity of extreme workouts among young consumers who are passionate about fitness and willing to spend big on self-care. (LATimes)
