Justin Bieber is undoubtedly one of the most famous faces on the planet, and is forced to contend with life in the public eye practically at every waking moment.

The 'Yummy' singer really does seem to have embraced clean living since his marriage to Hailey Baldwin. In a recent interview for the latest episode of his YouTube documentary series, he opened up on the subject of how he manages to stay sober.

In the third episode of his YouTube documentary series 'Seasons' Bieber stated that dis childhood anxiety spurred a so-called "dark period" in his late teens and early 20s, leading to a debilitating addiction to weed, opioids, and pills.

However, Bieber shared that he has since been diagnosed with a number of health conditions since going sober, such as chronic mono and Lyme's disease. He added that, in addition to using antidepressants, he also takes NAD+ infusions administered through an IV and uses a hyperbaric chamber to help himself sleep.

In a promo for the upcoming episode, Bieber can be seen climbing into the hyperbaric chamber (typically used to help divers suffering from decompression sickness), and describing how the machine pumps oxygen into the zipped chamber, to assist his breathing while unconscious.

Bieber states: "Mental health is so important to get on top of. If you have ADHD if you have… something and you don't want to take medicine, I strongly believe in it."

Commenting on her spouse's struggles in the promo, Hailey Bieber states: "I think when you take somebody very young and they start to get horrible, crazy, crippling anxiety and it goes undiagnosed and you don't know what it is that you're feeling, you start to self-medicate because it makes you feel better."

She added: "People are going to think this is some rich people sh*t."

However, medical experts are skeptical as to the hyperbaric chamber's track record at treating Bieber's aforementioned maladies. According to  Dr. Mark Calarco, National Medical Director for Clinical Diagnostics for the American Addiction Centers, there are no studies proving that hyperbaric oxygen therapy helps with anxiety.

Calarco told Insider: "If it's done properly and in a safe environment, the risks are low, so maybe there's some benefit there on an individual level. But we don't know."
