Create a thumbnail for our video on sleep and the harmful effects of blue light

Create a thumbnail for our video on sleep and the harmful effects of blue light at night. The thumbnail should be eye-catching and reflect the subject of the video. Use dark colors to represent the night and visual elements such as a light bulb, a phone or computer screen, and a sleep symbol (such as a bed or a crescent moon). You can also include an image of a person having trouble sleeping or covering their eyes to protect themselves from the light. Make sure the thumbnail is clear and easy to understand to encourage people to click on the video.
