"I have said this before but it's the truth," the face of Smartwater, who married Justin Theroux in July, told Goop. "I really think hydration is so important … and sleep! I drink Smartwater all day, every day, and I like the new Smartwater sparkling water at night with meals."

While the tip may seem obvious, Aniston admits that it can be especially hard to drink up to eight glasses of water a day. To help her achieve the goal, the Living Proof co-owner accessorizes with her H2O. "Carry bottles of water with you everywhere you go. During the not-so-hot season in Los Angeles I keep a case of Smartwater … in my car," she said on the Gwyneth Paltrow–run lifestyle site. "In the summer I keep a cooler in the car to keep it cold. When you carry a bottle with you all the time you just get into the routine of drinking a lot of water."

Aniston also credits regular exercise (yoga, elliptical workouts and treadmill running), a balanced diet and meditation as the secrets to her age-defying beauty. "We are as young as we feel and treating yourself right is a great way to feel good," she told Goop. "Being happy is also a key to looking and feeling younger."
