Castillo always makes time for herself to relax and unwind. Her way of doing so is by running a bath. She posted this photo on Instagram of herself in the tub. Baths have a lot of benefits, according to this post from The Cleveland Clinic. "Taking baths has great physical and mental health benefits," family medicine provider, Amy Zack, MD, says to the clinic. "One benefit is cleanliness. Bathing cleans your skin, helping you avoid irritation, inflammation and sores caused by dead skin cell accumulation. The bacterial and fungal load from contact in your environment can also accumulate, increasing the risk of infection."

Castillo loves to spend time outside. One of her favorite outdoor activities is to go on a hike. She posted this set of photos on Instagram of herself and some friends hiking in the forest and by the water. She captioned the post, "Magic is in the people you surround yourself with and the horizons you cross by their side."

Castillo is also a fan of surfing, and posted this set of photos posing with her board.
