Recently, Eilish addressed a moment where she walked away from fans on an episode of Jimmy Kimmel Live. She says that she decided to walk away because the situation wasn’t comfortable for her. "I started to walk away because I realized none of these people actually cared about anything that had to do with me as a person," she explained. "I walked over there only to say hi, only to hug people and I got pictures of me shoved into my face. I got no love whatsoever, so I left and then I got booed and [got] called a little b*tch and got told I was going to lose my Grammy nominations."

5. She Gets Her Vitamin D

Billie has been seen responsibly enjoying the sun. Sitting in the sun for 10 minutes a day can provide several emotional benefits. First, exposure to sunlight stimulates the production of serotonin, a neurotransmitter linked to mood regulation, promoting a sense of happiness and well-being. Sunlight also triggers the release of endorphins, known as "feel-good" hormones, which can reduce stress and alleviate symptoms of depression. Additionally, sunlight exposure helps regulate circadian rhythms, leading to better sleep patterns and improved overall mood. Finally, being outdoors and enjoying natural light can enhance feelings of relaxation, rejuvenation, and connection to nature, fostering a sense of calm and tranquility.
