Numerous studies have shown the health benefits of spending time outdoors. But a new study published in the Journal of Environmental Psychology suggests that watching sunrises or sunsets will improve your mood, and your mental health. Researchers at the University of Exeter found that participants who viewed not only sunsets in the evening or sunrises in the morning, but also rainbows, thunderstorms, and starry or moonlit skies, experienced increased perceptions of natural beauty and feelings of awe. The researchers believe that these increased feelings of awe sparked by these moments of outdoor beauty improve mood, enhance positive social behavior, and increase positive emotions.
