Regan spends a lot of time outside. She shares a bunch of outdoor photos and videos on Instagram. One thing she likes to do is go boating.

Regan doesn't just like to boat when she's spending time by the water. She shared a lot of posts on Instagram of herself swimming at the beach or the pool. Swimming has a lot of benefits for your health and wellbeing. The Mayo Clinic Health System reports, "Exercise in an aquatic environment offers numerous options and techniques for almost all levels of physical ability. Exercise can be as basic as walking in the water to more high-level aerobic activities, such as deep-water running or swimming. Standing exercises often are performed in water that is waist to chest deep. These exercises can focus on improving range of motion/flexibility, balance and strength. Resistance training can be amped up by simply increasing the speed of movement or adding equipment, such as mitts, paddles, noodles or bands, to increase drag."

Another outdoor activity Regan likes to do to stay in shape is going hiking. She shares a bunch of posts on Instagram of herself hiking. Regan shared these photos and videos of herself hiking in the Kauaeranga Valley. She captioned the post, "Forest diaries." She also shared this video of herself by a waterfall, captioning it, "Happy mooch in avatar land."

"Light-sensing cells in your eyes are part of a circuit that sends signals to mood-influencing parts of the brain, explains Judith Snell, a physician assistant specializing in primary care. Sunlight hitting the cells triggers feelings of happiness and well-being. And sun exposure is linked to the production of serotonin — a hormone associated with boosting your mood. That's why light therapy is often used to combat seasonal affective disorder," says Geisinger.

"The physiological response to being outside in nature is real, and it's measurable," said Michelle Kondo, a research social scientist with the USDA Forest Service's Northern Research Station, tells the USDA. "There are many physical and psychological benefits of nature that scientists have observed, which can better help us understand how nature supports wellness in the body, mind and community."
