So enters the weekend….that magical time when an analytic mind relaxes and enjoys life…….and as usual I will find those unusual topics on which to post…..
I exist on caffeine……coffee keeps the mind going and working at an incredible rate…..I have seen all the studies that say it is bad for a person….also the ones that say it is good and cannot hurt……and now there is a new study……
It’s no news flash that consuming caffeine close to bedtime can interfere with sleep. But scientists at the University of Colorado Boulder report in the journal Science Translational Medicine that caffeine has another physiological impact on sleep by delaying the body’s natural surge in the production of the sleep hormone melatonin, which in turn pushes back the body’s circadian clock. “To our surprise, no one had really tested this question,” one of the researchers tells NPR. “What we’re seeing here now is another way that caffeine impacts our physiology that we didn’t know about before in humans.”
The problem in this case is that the circadian clock is “present in cells throughout our entire body,” says the researcher. “It’s in your fat cells; it’s in your muscle cells.” Messing with it appears to play a role in a wide range of health problems, from obesity to cancer. Many studies have recently suggested that bright light at night, especially the blue light emanating from our screens, impedes melatonin production. Caffeine’s effect is about half what scientists found when exposing volunteers to bright light alone; volunteers who drank a double espresso three hours before bedtime experienced a 40-minute delay of the melatonin surge. Now the researchers plan to study whether caffeine consumption five or six hours before bedtime produces a similar effect.
Sleep? There is plenty of time for sleep when I crap out!
Next the fad….green tea. You have seen or heard the claims that green tea can do everything from weight loss to sexual prowess……
I bet there is one that you have not heard…….
A 16-year-old girl in England decided she was going to lose weight by drinking green tea, so she ordered two boxes online, the Telegraph reports. Most of the ingredients were written in Chinese, but the girl spent the next three months drinking three cups a day. According to ABC News, she had lost only a few pounds when she started suffering from nausea and joint and abdominal pains. She would eventually develop jaundice. “I was very scared when I was admitted to hospital and had lots of tests,” the girl says in a report published Wednesday in the British Medical Journal Case Reports. “I didn’t fully understand what was going on at the time.” The initial suspicion was a urinary tract infection, but it turns out she had acute hepatitis.
Doctors gave the girl intravenous fluids and medication—and made her stop drinking the tea—and she recovered quickly, ABC reports. According to the Telegraph, green tea has been rumored to be help everything from depression to breast cancer to dementia, thanks to its antioxidants. The report’s authors even “acknowledge that green tea is predominantly a very safe and healthy drink.” And while they didn’t test the girl’s tea, they believe chemical additives or pesticides were likely the cause of her hepatitis. One expert tells ABC that consumers need to be careful when buying herbal supplements or tea over the Internet. It’s a lesson one 16-year-old girl learned the hard way. “I will never buy any online tea again,” she says in the report
Personally I think green tea is an overrated consumer item….and now I know for damn sure I will not bother with it……
