In a recent Marie Claire magazine article, pop star Katy Perry spoke about her daily practice of transcendental meditation, explaining she likes to meditate in bed first thing in the morning for 20 minutes.

”I start the day with transcendental meditation,” she said. “It puts me in the best mood. I wake up and just prop myself up in bed for 20 minutes. It’s the only time my mind gets absolute rest. When I’m asleep, my subconscious mind is switched on and, when I’m awake, I’m alert.”

She also spoke about the importance of taking vitamins and probiotics for an afternoon boost of energy, and to help with digestion.

”Like everyone I have a four o’clock slump. I take vitamins after lunch and they give me an energy boost. I have iron, vitamins B, C and D and probiotics, which help with my digestion.”
