Santos enjoys fresh fruit bowls for a healthy start to the day, especially with strawberries. "One cup of strawberries (or about eight medium strawberries) has only 45 calories, 3 grams of dietary fiber (12 percent of your daily value) and more vitamin C than an orange," says Allyn Wergin, RDN to the Mayo Health Clinic. "Vitamin C is a known antioxidant that helps protect the body against oxidative stress."

Santos loves swimming, be it in the pool or ocean. "Whether you have a joint injury or are recovering from surgery, the water will allow you to stay active, maintain fluidity in your joints and activate multiple muscle groups," says Valerie Taraborelli, a physician assistant in orthopedic surgery at Banner Health in Arizona. "Swimming in warm water can be advantageous as this will allow for improved circulation that relaxes muscles and allows for safe execution of stretches and exercises."

Santos' favorite dessert is anything chocolate-based. "People who ate dark chocolate reported that they felt less stressed, and researchers confirmed that after eating dark chocolate, there were reduced levels of the stress hormone cortisol," says Johns Hopkins Health. "This may be related to dark chocolate's effects on heart health, since stress is a risk factor for cardiovascular disease."

Santos enjoys the many health benefits of bonding with a pet. "Stress is not the only problem which our bond to our pets can help," says Stanley Coren PhD, DSc, FRSC. "Up to 25% of people who go to general practitioners do so for depressive and anxiety disorders. Depression is actually considered to be much more disabling, both socially and even in terms of physical functioning, than many chronic physical illnesses such as diabetes, arthritis and back pain."

Santos is open about her cosmetic enhancements. "I'm all for it and I do it," she says. "I've already had lip fillers. My mouth has always been fleshy, but I put it on the upper part. I also do Botox and filler for dark circles and even peeling and skin cleansing."
