In one of her latest social media posts, the Bachelor star flaunts her incredible figure in a bathing suit while having fun in the sun.

One way Serene relaxes and indulges in self-care is by soaking in hot water. How can a bath or jacuzzi soak benefit your health? They have been linked to better sleep and even found helpful to minimize anxiety and depression. One recent study even found that they may even boast cardiovascular benefits.

Serene also blasts calories with outdoor activities, including kayaking. "Missin my outdoorsy bff," she captioned this post. Kayaking is a great workout. Not only is it great for building upper body strength and helps reduce stress, but can burn up to 400 calories per hour, translating to 1,600 calories in four hours of paddling.

Serene practices self-love and acceptance. "The biggest thing I learned about myself is that I do deserve grace. I've always been really hard on myself and didn't always allow myself to feel things. That's been the biggest thing, getting to watch myself say things out loud for the first time and seeing my growth on the show has been really impactful for me," she told Bachelor Nation.

What is Serene's favorite food" "Enchiladas with sour cream sauce," she told Bachelor Nation. "TexMex is my whole life." 

Serene starts her morning off with a jolt of caffeine. "Get that big stretch in and make espresso. I'm a night owl so I need the extra help getting started," she told Bachelor Nation. According to the Cleveland Clinic, there are several benefits of drinking coffee in moderation. "It acts on your brain to improve memory, mood, reaction times, and mental function," they say, citing a study finding that caffeine can improve endurance and performance during exercise. It is also antioxidant-rich, can ward off diabetes, prevent neurologic disease, lower cancer risk, and ward off depression, they point out.
