Insufficient and poor-quality sleep is linked to multiple health concerns. A new study has found that abnormal sleep patterns disrupt the body's natural biological clock and have been linked to lung health issues. The study was published in the journal, 'Nature Communications'. Researchers have shown how a biological clock molecule, called REV-ERBa, contributes to lung scarring, uncovering new potential drugs and drug targets along the way.

Pulmonary fibrosis, or lung scarring, is a serious condition in which connective tissue builds up in the lungs, making them thick and rigid, and causing difficulty breathing. While medications can ease the symptoms of pulmonary fibrosis, none can repair the lung damage caused by this sometimes-fatal disease.
