Circadian rhythm sleep disorders |
|||
Text 
Signals are transmitted to the body clock to convey sleep time and wake up time. Sunlight, by far is the most potent of wake up signals (also called ‘Zeitgeber’). Weather, darkness and sound are other significant signals received by the body. Circadian rhythm disorders are caused when the body clock is unable to recognize and interpret these signals correctly. “Circadian” in Latin means ‘for about a day’. There can be a discrepancy between a person's sleep-wake pattern (internal clock) and the sleep-wake demands of the individual’s environment. This mismatch can cause insomnia or excessive daytime sleepiness. Some of the circadian rhythm disorders are -  Jet lag, Shift work sleep disorder, Irregular sleep-wake pattern Delayed sleep phase syndrome, Advanced sleep phase syndrome Non-24-hour sleep-wake disorder.

Posted on: 04/17/2013 I am 66 years old woman. Lately I am experiencing that in the middle of the night I am howling due to some terrible nightmare, generally I realise in sleep that I am howling, I get awakened, mostly am unable to recall the dream sequence, but a general feeling of dread is there. It is disturbing my family. I am on a drug [ pentoprazole] stomach disorder. Kindly help.
