Avoid Backlit Reading Before Bed

During a recent experiment, all participants read for five nights on an iPad and for five nights from a book. As anticipated, reading something in print made for a better sleep. Participants reading the iPad took about 10 minutes longer to fall asleep, secreted less sleep-inducing melatonin, and shifted their internal circadian clock. They also reported feeling more tired the next morning. （Scientific American）

睡前閱讀電子書影響睡眠質(zhì)量

所有的參與者都按照要求連續(xù)5 晚閱讀平板電腦或紙質(zhì)書。紙質(zhì)書閱讀組如預(yù)期般有著更好的睡眠。而平板組要花10 多分鐘才能入睡，睡眠中分泌的褪黑激素也比較少，而且自身內(nèi)在的生物鐘也受到影響。同時(shí)他們還表示第二天醒來會(huì)感覺更累。

Eating Less Helps you Live Longer

Researchers in the United States say eating less can slow the ageing process of cells in the body. Calorie restriction caused real biochemical changes that slowed down the rate of ageing. Fewer calories slow down a natural mechanism that occurs in cells.（Voice of America）

少吃可以延緩衰老

美國(guó)的研究人員稱，少吃能夠延緩體內(nèi)細(xì)胞的衰老速度。限制卡路里攝入真的會(huì)出現(xiàn)延緩衰老速度的生理變化。較少的卡路里減慢了細(xì)胞內(nèi)核糖體的自然機(jī)制。

Light Music Reduces Fast Food Meal Size

Now a study has found that changing the ambiance of a fast food restaurant to more of a fine-dining atmosphere with light music lessened the amount of food people crammed into their pie holes. The patrons actually averaged 18 percent fewer calories per meal than the folks in the rowdy section—down from an average of 949 calories to 775.（Scientific American）

輕音樂降低進(jìn)食量

有一項(xiàng)研究發(fā)現(xiàn)，將快餐店的環(huán)境氣氛改裝得更精美，會(huì)使人們減少填進(jìn)肚子里的食物總量。實(shí)際上，相比在吵鬧的區(qū)域進(jìn)食的顧客，這里的顧客平均每餐少消費(fèi)18% 的卡路里，從平均的949 卡路里降至775 卡路里。

Should You Charge Your Phone Overnight?

Frequent charging takes a toll on the lithium-ion batteries in our phones. And it's not because they are overcharged. Smart phones know when to stop charging. So in theory, any damage from charging your phone overnight with an official charger, or a trustworthy off-brand charger, should be negligible.（The New York Times）

給手機(jī)徹夜充電會(huì)影響電池壽命嗎？

頻繁充電會(huì)傷害手機(jī)的鋰離子電池，原因并不在于它們會(huì)被過度充電。智能手機(jī)知道該在何時(shí)停止充電。因此，理論上用原廠充電器或信得過的品牌充電器為手機(jī)徹夜充電所造成的損害基本可以忽略不計(jì)。
