Explain the circadian rhythm.?

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. ...Read more

This nucleus tells the pineal gland when to secrete melatonin, the hormone that tells us when we're supposed to get sleepy. ...Read more

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. ...Read more

To sun lamps help with circadian rhythm disorder?

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... ...Read more

How does travel change your body's circadian rhythm?

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. ...Read more

Is there a body clock that governs our circadian rhythm?

Yes: Natural circadian rhythm is known to be 25 hours. The "clock" is in the part of the brain which computes our ability to adapt to the mental and physical stresses imposed by environment. We compress the 25 hour to a 24-hour rhythm, thus adapting to our world. The 24-hour rhythm obeys the dark/light cycle and is indeed controlled by the computer in the brain. ...Read more

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

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. ...Read more

What's better: to find and keep my own circadian rhythm, or try to orientate my rhythms to the sun?

Circadian external: Unfortunately the circadian rhythm has to do with all external factors not our own "internal clock" since that is under another mechanism of homeostatic sleep drive. To orient yourself, using external clues like th sun is important. Don't underestimate unplanned light (like computers, televisions and phones) that are working against us (esp. At night). ...Read more

It is important that you choose the one that aligns with your body-mind-spirit. It takes some knowing yourself to do this. There certainly are people who are night owls and this works for them. But, in general, unless you have special needs, aligning with the sun is always good. ...Read more

I think I broke my circadian rhythm. I'm now waking up before the sun even comes up. How to reset it?

Takes time : Jet lag recovery takes time, some say a full day for every hour of time zone change to fully recover. Use morning coffee, daylight exposure and exercise to maintain alertness and try to stay up until "bed time" at your destination (even if destination is "home"!). ...Read more

The circadian rhythm helps regulate a person's sleep/wake cycle, and is affected by variations in the environment, such as the amount of daylight, the length of the night, the ...Read more
