A human body can think thoughts, play a piano, kill germs, remove toxins, make a baby all at once. Once it's doing that your biological rhythms are actually mirroring the symphony of the universe because you have circadian rhythms, seasonal rhythms, tidal rhythms you know they mirror everything that is happening in the whole universe.— Michio Kaku
Famous Circadian Rhythm quotations
Five hours' New York jet lag and Cayce Pollard wakes in Camden Town to the dire and ever-circling wolves of disrupted circadian rhythm.
You can get the highest quality sleep by keeping your sleep cycles in tune with the rhythms of the universe (known as circadian rhythms).
We're not really sure why it [broken circadian rhythm] continues, but when they become adults, we usually have to treat it because many people need to get up early to go to work and they can't be sleeping until 11:00 or 12:00. So we use treatments like bright light therapy, melatonin, things like that that are very effective.
So someone who is a child usually goes to bed about 8:00 or 9:00 at night, but then when they have a circadian rhythm shift, it shifts later. And this is natural. And they start to go to bed at 11:00, 12:00, 1:00 and they want to sleep later. So we see this a lot in teens.
It's uncommon, but there are some people who just have a delayed circadian rhythm and they just - they sleep better during the day then they do at night. So they've - a lot of those people with delayed sleep phase disorder they start to work in bars, they work some of the late night shifts, they sort of adjust to doing it more and more as time goes on.
We have other opposite problems with circadian rhythms that can happen when you - a lot of times with older adults. They start to go to bed at 6:00, 7:00 at night and they wake up at 2:00 in the morning. And they're rhythms actually shift earlier, but sometime it can just kind of miss the mark and shift too much earlier and that's when we need to treat it with bright light.
Now circadian rhythms become very interesting and problematic for patients because when you become a teenager, your rhythms actually tend to naturally shift.
So when it comes to circadian rhythms, it's a clock that's basically programmed in our body. So if you think back to times when people lived on farms and we didn't have electricity.
Things that live by night live outside the realm of 'normal' time and so suggest living outside the realm of good and evil, since we have moralistic feelings about time. Chauvinistic about our human need to wake by day and sleep by night, we come to associate night dwellers with people up to no good at a time when they have the jump on the rest of us and are defying nature, defying their circadian rhythms.
Lithium tweaks many mood-altering chemicals in the brain, and its effects are complicated. Most interesting, lithium seems to reset the body’s circadian rhythm, its inner clock. In normal people, ambient conditions, especially the sun, dictate their humors and determine when they are tuckered out for the day. They’re on a twenty-four-hour cycle. Bipolar people run on cycles independent of the sun. And run and run.
A disruption of the circadian cycle—the metabolic and glandular rhythms that are central to our workaday life—seems to be involved in many, if not most, cases of depression; this is why brutal insomnia so often occurs and is most likely why each day’s pattern of distress exhibits fairly predictable alternating periods of intensity and relief.
