Are you experiencing depression, mood instability, and loneliness? Blame the disruption in your body's internal clock, researchers say.

Our 24-hour biological body clock governs the fundamental physiological and behavioural functions including from body temperature to eating habits in almost all organisms. Disruptions in that biological clock may arise from increased activity during rest periods and/or inactivity during the day. Disturbances to the body's internal clock or the circadian rhythms are also associated with lower happiness and health satisfaction, and worse cognitive function, according to a study published in The Lancet Psychiatry.
