1. Tea off in the morning
Hot tea can slash your risk of kidney cancer by 15 percent, according to a review in the International Journal of Cancer. Try pu-erh tea, which is better than green or black tea at preventing DNA damage.
2. Sleep smarter
Too much sleep, or not enough of it, can kill you. A British study found that getting more than 9 hours of sack time a night, or less than 6, doubles your risk of an early death from any cause. Aim for 7 to 8 hours a night.
3. Pop in your lenses post-shower
Soaping up while wearing your contacts can expose your eyes to infection-causing waterborne microbes, say University of Illinois at Chicago researchers.
4. Drink wine, stay lean
Polyphenols, the compounds found in red wine, help your body block fat absorption, an Israeli study found. Red-wine marinades work, too.
5. Lose the lint
Taking 2 seconds to empty the lint trap in your clothes dryer can prevent you from being one of the 315 dryer-fire victims each year in the United States.
6. Check your neck
An American Journal of Medicine study found that a mildly underactive thyroid can boost your heart-disease risk by 65 percent. A quick blood test can assess your level of thyroid-stimulating hormone (TSH).
7. Lean back
Parking your torso at a 90-degree angle strains your spine, say Scottish and Canadian researchers. Instead, give your chair the La-Z-Boy treatment and recline the seat back slightly. The ideal angle is 45 degrees off vertical.
8. Scent your air safely
Some air fresheners contain phthalates, compounds that may disrupt hormone processes, Natural Resources Defense Council testing reveals. Stick with Febreze Air Effects and Renuzit Subtle Effects.
9. Boost your defenses
An Archives of Internal Medicine review reports that 400 IU of vitamin D a day reduces your risk of an early death by 7 percent. Try Carlson's vitamin D.
10. Skip the spray
Using household spray cleaners just once a week increases your risk of an asthma attack by 76 percent, say Spanish researchers. Use wipes instead.
11. Steam your broccoli
Italian researchers recently discovered that steaming broccoli increases its concentration of glucosinolates (compounds found to fight cancer) by 30 percent. Boiling actually lowers the levels.
12. Stretch it out
Genes in your body linked to heart disease, diabetes, and obesity can be "turned on" if you sit for hours on end, reports a study in Diabetes. Hit the "off" button by taking hourly laps during TV, book, and Web sessions.
1.早上饮茶
根据《国际癌症杂志》的一份评述，热茶能够使肾癌发病率降低15％。试试普洱茶，它能比绿茶或红茶更有效阻止DNA受损。
2.适度睡眠
睡得太多，或睡得太少，都损害健康。一项英国的研究发现，每晚睡眠时间超过9小时，或者不足6小时，不分何种缘由，会使你早死的危险翻一翻（汗呐，两条我都占了）。每晚睡眠目标7～8小时。
3.沐浴后再戴隐形眼镜
芝加哥伊利诺伊大学（译者注：不只一个University of Illinois，在芝加哥的又叫UIC）的研究人员说，带着隐形眼镜搓肥皂，会将你的眼睛暴露给传染性水生微生物。
4.喝葡萄酒长不胖
一项以色列的研究发现，多元酚－－红葡萄酒中一种化合物，能帮助人体阻止脂肪的吸收（译者注：红酒多酚的功效不仅如此，原来还能防乳腺癌和前列腺癌；而且比其它的多酚要更好！赶紧去买两瓶红酒）。红葡萄酒做的腌泡汁也有同样功效。
5.清理绒毛线头
花上两秒钟，清理干净你家衣服烘干机里的过滤网。美国每年有315人死于干衣机引起的火灾。你不想成为他们中的一员吧？
6.检查一下脖子
《美国医学杂志》上的一项研究发现，轻度甲状腺功能不足会使你患心脏病的危险增加65％。一次快速血检就可以测出你的甲状腺激素（TSH）水平。
7.向后靠靠
苏格兰和加拿大的研究人员指出，保持躯干90度会使你的脊椎劳损。不要这样坐，把你的椅子换成拉兹男孩治疗椅（译者注：La-Z-Boy是著名的家具公司，套句广告词，La-Z-Boy就是“舒适与优质”的同义词），把椅背稍稍向后仰，理想的角度是水平45度。
8.使用安全的空气清新剂
自然资源保护委员会（译者注：NRDC是总部设在纽约的，美国最有影响力的环境保护团体）的检测显示，一些空气清新剂含有邻苯二甲酸盐，一种可能破坏荷尔蒙代谢过程的化合物。建议坚持使用Febreze Air Effects 和Renuzit Subtle Effects。
9.增强抵抗力
英国《内科学文献》一份评述说，每天服用400国际单位的维他命D，使你早死的危险降低7％。试试卡尔森研究中心的维他命D。
10.别用喷雾剂
西班牙研究人员说，只要每周使用家用喷雾清洁剂一次，就会使你哮喘病发病机率增加76％�；故怯媚ú及伞�
11.蒸着吃西兰花
意大利研究人员最近发现，蒸西兰花可以使其芥子油甙浓度（一种能抗癌的化合物）增加30％。用水煮实际上降低其浓度。
12.起来活动
《糖尿病杂志》上的一篇研究报告称，一坐几小时不动，人体内与心脏病、糖尿病和肥胖症有关的基因就会“启动”。要“关上”按钮，看电视、读书或上网时，每隔一小时就要起来活动活动。
