Coronary stent thrombosis joins several other adverse cardiac events that also follow a circadian pattern, such as stroke, unstable angina pectoris, acute myocardial infarction and sudden cardiac death, according to researcher published in JACC: Cardiovascular Interventions. Most studies that addressed circadian variations in cardiovascular disease were done before the advent of stents, so, researcher from Mayo Clinic-Rochester conducted a retrospective analysis of medical records and the clinic’s registry, finding 124 patients who presented with coronary stent thrombosis betwee...

Lack of light is one of the reasons that people feel mentally foggy. One of the bloggers I follow, Rachel Zimmerman of WBUR’s CommonHealth blog, recently wrote that she’s been drinking three times as much coffee as usual. In addition to imbibing more caffeine, I’ve been trying to boost my spirits and alertness with mid-day runs to the snack machine (not the best strategy, in case you’re wondering). At this time of year, many people aren’t just foggy and sad — they’ve got SAD, or seasonal affective disorder. About half a million Americans — women more often than men — are diagnosed with seasonal affective disorder each year. Ma...

A recent circadian rhythm study in hamsters showed that hamsters that “exercised” (more “wheel running” ) drank less alcohol than those restricted from exercise. Does your alcocholic husband or alcoholic wife go to sleep at all hours of the night and get up at different times during the day? Has your alcoholic spouse lost a routine for both their sleeping habits and eating habits? Bottom line: their alcohol abuse is disrupting their circadian rhythm which can also trigger alcoholic relapse in someone who has been abstinent. Dr. David Glass, Professor of Biological Sciences came to this conclusion after studying hamsters and “wheel running”. The hamsters that were restricte...

Scientists discovered a rare genetic mutation that allows certain people to sleep on less hours without any adverse effect. In one family, a mother and daughter with this rare mutation needed only six hours of sleep each night while the rest of the family needed the typical 7-8 hours. Gene for Short Sleeper Found. Image: sxc Published in Science, researchers from the University of California- San Francisco isolated the gene as DEC2, involved in the regulation of circadian rhythms, the body’s clock. The scientists then bred mice and fruit flies that carried the mutation and found the mutant mice slept less and needed less time to recover from sleep deprivation. According to health experts, a typical adult needs at least 7-8 hours of sleep each...

SAD can actually affect people during any season, including the bright and sunny days during spring and summer months; however, according to a recent Swedish study, regardless of the similar symptoms, SAD doesn’t seem to be the culprit when it comes to the high number of suicides happening in places that experience extended sunlight like Sweden and Greenland. The researchers speculated that light-generated imbalances in serotonin — the brain chemical linked to mood — may lead to increased impulsiveness that in combination with a lack of sleep drives people to kill themselves. “We found that suicides were almost exclusively violent and incre...

Numbers such as 30.04 will be followed by “rising,” “falling,” or “steady.” Typically, when a low pressure front is coming (and they do, all the time) it signals not only a change in the weather, but a drop in the barometric pressure, which is pressure against the Earth’s atmosphere. Remember when Grandma would say, “Rain’s coming, and I can feel it in my joints?” She actually knew this because of what happens to our bodies when the barometric pressure changes. That means that the pressure against your body drops as well, and your joints and areas that are injured can begin to swell. This swelling causes increased inflammation, and we require hormones to deal with this incr...
