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.早上飲茶

根據《國際癌癥雜志》的一份評述，熱茶能夠使腎癌發病率降低15％。試試普洱茶，它能比綠茶或紅茶更有效阻止DNA受損。

2.適度睡眠

睡得太多，或睡得太少，都損害健康。一項英國的研究發現，每晚睡眠時間超過9小時，或者不足6小時，不分何種緣由，會使你早死的危險翻一翻（汗吶，兩條我都占了）。每晚睡眠目標7～8小時。

3.沐浴后再戴隱形眼鏡

芝加哥伊利諾伊大學（譯者注：不只一個University of Illinois，在芝加哥的又叫UIC）的研究人員說，帶著隱形眼鏡搓肥皂，會將你的眼睛暴露給傳染性水生微生物。

4.喝葡萄酒長不胖

一項以色列的研究發現，多元酚－－紅葡萄酒中一種化合物，能幫助人體阻止脂肪的吸收（譯者注：紅酒多酚的功效不僅如此，原來還能防乳腺癌和前列腺癌；而且比其它的多酚要更好！趕緊去買兩瓶紅酒）。紅葡萄酒做的腌泡汁也有同樣功效。

5.清理絨毛線頭

花上兩秒鐘，清理干凈你家衣服烘干機里的過濾網。美國每年有315人死于干衣機引起的火災。你不想成為他們中的一員吧？

6.檢查一下脖子

《美國醫學雜志》上的一項研究發現，輕度甲狀腺功能不足會使你患心臟病的危險增加65％。一次快速血檢就可以測出你的甲狀腺激素（TSH）水平。

7.向后靠靠

蘇格蘭和加拿大的研究人員指出，保持軀干90度會使你的脊椎勞損。不要這樣坐，把你的椅子換成拉茲男孩治療椅（譯者注：La-Z-Boy是著名的家具公司，套句廣告詞，La-Z-Boy就是“舒適與優質”的同義詞），把椅背稍稍向后仰，理想的角度是水平45度。

8.使用安全的空氣清新劑

自然資源保護委員會（譯者注：NRDC是總部設在紐約的，美國最有影響力的環境保護團體）的檢測顯示，一些空氣清新劑含有鄰苯二甲酸鹽，一種可能破壞荷爾蒙代謝過程的化合物。建議堅持使用Febreze Air Effects 和Renuzit Subtle Effects。

9.增強抵抗力

英國《內科學文獻》一份評述說，每天服用400國際單位的維他命D，使你早死的危險降低7％。試試卡爾森研究中心的維他命D。

10.別用噴霧劑

西班牙研究人員說，只要每周使用家用噴霧清潔劑一次，就會使你哮喘病發病機率增加76％。還是用抹布吧。

11.蒸著吃西蘭花

意大利研究人員最近發現，蒸西蘭花可以使其芥子油甙濃度（一種能抗癌的化合物）增加30％。用水煮實際上降低其濃度。

12.起來活動

《糖尿病雜志》上的一篇研究報告稱，一坐幾小時不動，人體內與心臟病、糖尿病和肥胖癥有關的基因就會“啟動”。要“關上”按鈕，看電視、讀書或上網時，每隔一小時就要起來活動活動。
