Summer Fridays' Marianna Hewitt and Lauren Ireland Share Their Must Haves

Much like her morning routine, Ireland's nighttime routine is designed to set her up for success — and in this case, a restful night of sleep. "I swear by a hot cup of magnesium tea each night just before bed," Ireland says. Her product of choice is the Moon Juice Magnesi-Om ($42). "It always improves my quality of sleep and eases any nighttime anxiety I may be having."

Pro Tip: Magnesium is an essential mineral that plays a role in many different processes in the body. Though more data is needed to directly link magnesium and sleep quality, supplements are currently getting a lot of attention for their ability to lower cortisol levels, allowing you to feel relaxed and ease anxiety.
