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

can you tell me how to re-set my circadian rhythm?

Accepted Answer

Exercise in day: One of the best ways to reset your circadian rhythm (e.g. after jet-lag or shift work), is to make sure you exercise, at least 15 minutes during the daylight.  Ideally &gt;6 hours before bed time.  Also, wake up at your desired time, don't take naps, and avoid caffeine 6-8 hours before bedtime.  Avoid T.V. in bedroom, to prevent insomnia.

Question 3

how does melatonin relate to circadian rhythm disorder?

Accepted Answer

Melatonin: Melatonin feeds the system in regards to pineal glad.  Melatonin is the "anti light hormone" so when our body should be preparing for sleep at night, melatonin is secreted telling us to prepare for sleep.  What it is not is a sleep aid.  Taking supplemental melatonin can be helpful if we are relatively difficient or are trying to iatrogenically adjust our rhythm (shift work, jet lag, etc).

Question 4

explain what melatonin has to do with circadian rhythm?

Accepted Answer

Resets clock: Your internal clock (circadian rhythm) does not run exactly 24 hours. Both sunlight and melatonin produced by the brain 'tell' your internal clock when morning and evening are occurring. This resets your clock so it can be aligned with external 'real world' time. Melatonin lets your internal clock know when the end of the day (bedtime) is occuring.

Question 5

how do i reset my circadian rhythm after 22 hour flight?

Accepted Answer

Proper rest: Circadian rhythm is night/day responsive. By normal sleep it will reset.

Question 6

how do i change my circadian rhythm for a trip to shanghai?

Accepted Answer

Change schedule: Depending how long before your trip, change your schedule 15 to 30 minutes everyday closer to the time it will be when you arrive in china. In other words change your "time zone" before you travel.

Question 7

can the work on or  light from a computer mess up your circadian rhythm?

Accepted Answer

Yes: The bluish color emited by computer monitors, tvs and other screens supresses melatonin production. Melatonin is your body's natural sleep hormone; it helps set your internal clock. When it is supressed you don't feel sleepy or  sleep poorly.  If you are bothered by computer work or tv watching simply turn off the devices 4 or more hours before bedtime to allow your body to release melatonin.

Question 8

is it ok that i always sleep at 2am and wake at 8am-9:30am? does it affect my circadian rhythm badly?

Accepted Answer

Sleep: If it is not causing distress or affecting your life or work or causing symptoms you should be fine, you are getting enough hours of sleep.

Question 9

is it possible to regulate circadian rhythm using temperature? i cannot see, and so light is useless.

Accepted Answer

No: It is not your body only. External celestial objects play a role.

Question 10

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.
