Casán is passionate about her collagen supplements. "Increasing collagen intake can go a long way to make your skin appear more firm and smooth," says Amy Myers, MD. "Collagen can also benefit the appearance of your hair's fullness and shine. Many people don't realize that adding collagen to your diet can also help in reducing the appearance of cellulite and stretch marks. When skin loses its elasticity and becomes thin, cellulite becomes more obvious. Collagen benefits your skin by increasing moisture retention, boosting elasticity, and helping to smooth out that dimpled appearance."

Casán loves to dance and perform. "We know that movement is good for everyone," says Emily Sandow, supervisor of dance physical therapy at NYU Langone's Harkness Center for Dance Injuries. "A healthy lifestyle is integrating the mind, body and soul relationship, and dance has all of those characteristics. Everyone can do something, even if it's just you just tapping your foot. Everyone can do something where they can move their body to music, and that's really valuable."

Casán enjoys the many health benefits of being at the beach. "Blue spaces provide us with distractions that take our mind away from the day-to-day hassles of life," says Kate Campbell, a health psychology researcher at Te Herenga Waka-Victoria University of Wellington, New Zealand. "The sound of the crashing waves, the smell of salty air, the crunching of sand beneath our toes…The sensations relax our bodies and tell our minds to switch off."

Casán is dedicated to her family, and enjoys spending time with her loved ones. "When you spend time together as a family—talking about your day, your highs, your lows—it fosters communication," says Licensed Marriage & Family Therapist Rossana Snee. "As parents, it gives you the chance to listen to your children, to hear them out, to learn about what's going on in their world. It also provides you with the opportunity to use life situations as teaching moments."

Casán is passionate about social justice issues, and frequently attends rallies in support of minorities. When we do good deeds we're rewarded by a dopamine pulse," says bioethicist Stephen G. Post, co-author of Why Good Things Happen to Good People. "Giving a donation or volunteering in a food bank tweaks the same source of pleasure that lights up when we eat or have sex. It's clear that helping others, even at low thresholds of several hours of volunteerism a week, creates mood elevation."
