Question 1

explain the circadian rhythm.?

Accepted Answer

Circadian rhythm: Circadian rhythm refers to a natural physiologic cycle in which certain processes ebb and flow in a predictable pattern over the day. In humans the basic cycle is tied to the sun with sleeping at night and activity during the day. But there are other cycles. For example, your lung airways naturally get tighter at night (4 am) and that is why asthma patients often get their first symptoms at night.

Question 2

what governs our circadian rhythm ?

Accepted Answer

Light / dark: The brain takes in light in decreasing and increasing amounts depending on time of day and time of year, and a center in the brain, the suprachiasmatic nucleus, placed over the optic nerves, takes the information, and sets the "internal clock". This nucleus tells the pineal gland when to secrete melatonin, the hormone that tells us when we're supposed to get sleepy.

Question 3

can you change your circadian rhythm?

Accepted Answer

Yes: Circadian rhythms are both set by internal molecular clocks as well as responsive to environmental forces, the most powerful being light in the case of the sleep-wake cycle. This is one reason why some peoples normal clock may get delayed. Some individuals are more sensitive to adjustments and others more difficult. Be careful to adjust your rhythm on your own. Get advice from a sleep doctor.

Question 4

what's your circadian rhythm based on?

Accepted Answer

24 hour rhythms: Circadian rhythms are biological processes that typically oscillate on 24 hour patterns.  These processes repeat independent of external stimuli, but can be altered by external stimuli.

Question 5

are circadian rhythm disorders hereditary?

Accepted Answer

Circadian rhythm: Good question.  The short and long answer is yes.  Advanced sleep phase and delayed have a well-established genetic link.  The other circadian disturbances are not so well established (free running type or irregular sleep/wake schedule.

Question 6

what will make your circadian rhythm be off?

Accepted Answer

Long distance travel: Across numerous time zones. Or rarely from a pituitary tumor. These two examples are assuming that your circadian rhythm was working normally in the first place. Many people have an abnormal circadian rhythm, for totally unknown reasons causing them to produce more urine by night than during the day. This causes bedwetting in some subjects.

Question 7

to sun lamps help with circadian rhythm disorder?

Accepted Answer

They do: I've been practicing medicine in the midwest for 23 years. Between october and march, we may get 2-3 minutes worth of sun in 6 months. Vitamind deficiency is scarily common here, so anything that can safely provide light therapy without increasing skin damage i strongly recommend.Sorry, i might have exaggerated a bit on the midwest sunlight thing. We get 10 minutes...

Question 8

how does travel change your body's circadian rhythm?

Accepted Answer

Time change: Time change and when it gets lights and dark affect your circadian rhythm.  Body is responding to light and dark cues so when people travel those clues are given at "incorrect" time.  Your body doesnot kow what to expect until it adapts over a few days.  In general expect about 1-2 days for every hour of time difference.

Question 9

why our circadian rhythm changes its pattern sometimes?

Accepted Answer

See below: By definition, a circadian rhythm can be adjusted/reset by external stimuli.  The best example of this is changing of our sleep schedules after overseas trips.

Question 10

how do you use a sun lamp for a circadian rhythm disorder?

Accepted Answer

Morning: It must be full spectrum white light. These are expensive. Used for "winter blues", technically known as seasonal adaptive disorder causing  depression. Exposure to this light for about 2 hours at sunrise is often curative. The incas used to lie down at sunrise to expose themselves to the sun as part of their health program.
