Several products help shift the body clock to wake up early.
If you need to seek light when it is dark outside, a portable light box will help. Light boxes shine bright light (around 10,000 lux) that can shift the body clock.
If you need to see clearly (e.g., to drive) when you should be avoiding light, wear blue-blocker sunglasses. They block the blue light that has the strongest effect on the body clock.
If you cannot control light exposure when you have to avoid light, wear very dark sunglasses.
