What does 'See some light' mean?
Get whatever light exposure you can - it doesn’t need to be bright! More importantly, make sure to avoid darkness, and remember not to wear your sunglasses.
Raise the window shade if it’s light outside, turn on the overhead light, and turn on the TV or use your laptop or tablet.
Why do I need to expose myself to light?
Light is the most powerful factor in resetting circadian rhythms and reducing jet lag. The effects of light vary by time of day, however, and it’s important to maximize light exposure to support the overall plan and make sure you’re not exposing yourself to darkness, which will derail the plan.
What will happen to my jet lag if I don’t get some light at this time?
The light timing is planned to help reset your circadian rhythm as quickly as possible. If you don’t see any light at this time, it will take longer to overcome your jet lag. As long as you are exposed to daylight or normal indoor light levels, you will be supporting the plan. Remember not to wear sunglasses at this time — that would block the benefits of light.
