Create a vision board collage centered around the theme of health, depicted in an electrifying neon punk style. The collage should incorporate numerous health-related items and symbols, such as a heart rate monitor, fruit, vegetables, running shoes, weights, yoga mats, and water bottles. These elements should be accentuated with a color palette featuring vibrant, luminescent hues typical of the neon punk aesthetic, like hot pink, electric blue, radioactive green, and cyber yellow. The background can be an urban cityscape speckled with futuristic technological elements. Keep the overall mood energetic and positive, encouraging a healthy lifestyle.
