People with coma can be brought to their normal life by making shinning of bright lights on them by remembering natural circadian rhythms said Researchers from Austria.

The patients have severe head injuries and their bodies to recover from brain damage is of natural circadian rhythms. A circadian rhythm is a 24 hour cycle in the physiological processes of living beings.  It depends upon the type of injury on the brain they have observed a group of 18 patients in different unconscious states. The possibility of getting consciousness may improve once the body falls back into its natural, healthy cycle of rising and falling body temperatures throughout the day.

The eight patients has changes in increased levels of consciousness after a treatment with carefully timed bright lights that were used has got tremendous changes with circadian rhythm activity and natural daily body-temperature fluctuations and the tests proved the recovery from coma said study leader Christine Blume, University of Salzburg in Austria.

The circadian rhythm served as a diagnostic tool for recovering the comatose patients. The rhythm cycle is a therapy technique which remembers brain the body when to eat, sleep or wake by this the temperatures in body start fluctuation and cause the awareness about daily routine cycle of their life and has high possibilities of recovering. Some were treated with unresponsive wakefulness syndrome, also called a vegetative state. People in this state have awakened from a coma which is a state of complete unconsciousness, and may open their eyes and have hours of sleep but otherwise remain unresponsive. Other patients in the study were in a minimally conscious state, meaning that they showed some signs of awareness.

The researchers turned up these patients to cyclical sessions of bright light stimulation over the span of a week. Two participants changed positively to this therapy, with increased signs of consciousness.
