To hear most recent research tell it, coffee is a miracle drink. The magic beans will prevent skin cancer and Alzheimer's (老年痴呆症), reduce heart failure and diabetes (糖尿病) risk, height focus, and even protect liver health. The miracle drink even decreases suicide risk, according to the newest study that justifies our coffee addictions.
According to a study performed by Harvard School of Public Health and published this month in The Word Journal of Biological Psychiatry, people who drink two to four cups of coffee each day are less likely to commit suicide than those who don't drink coffee, drink decaf, or drink fewer than two cups each day. The study followed over 200,000 people for at least 16 years. And it's not just a weak link: the researchers found that the suicide risk was cut by around 50 percent coffee addicts.
This isn't the first time that researchers have discovered that coffee and smiles might go hand in hand. A 2011 study found that women who drink coffee cut their risk of depression by 15 percent compared to those who don't. Michel Lucas, the head researcher of the most recent study, told The Huffington Post that coffee addicts can thank caffeine for the good news. The drug may actually act like a mild anti-depression by adjusting levels of happy hormones.
Of course, there's plenty of research out there that doesn't look so kindly upon coffee drinkers. Recently, the New Yorker published an article arguing that while coffee may heighten focus, it also puts a squeeze on creativity. And of course, coffee's well-known negative effects like insomnia (失眠症) and disturbed sleep cycles still hold.
Regardless, we'll raise our mugs to this most recent study for justifying our coffee addictions once again.
