Luna withstood freezing temperatures for cryotherapy.
On November 23, Luna shared a video of her in a cryotherapy session. She captioned, "I feel like a vegetable at E Mart. I started cryotherapy to build endurance ahead of important shoots. I decided to invest 3 minutes 2 times a week!! I'm going to regularly have cryotherapy. It goes down to negative 130 degrees. It's colder than I imagine. The 3 minutes feel so long... but I can do it."
Cryotherapy is a cold sauna primarily targeted for rheumatism patients. It's also used for cosmetic purposes. Remaining in cryotherapy at -110 to -170 degrees for 3 minutes helps with breaking down fat faster. In the past, rapper Swings was known for using cryotherapy for weight loss. Sulli has also shared videos of her undergoing the treatment.
Is that safe? I think I would get very sick if I'm exposed to that kind of cold.
