will sunglasses impact the morning sunlight routine

Wearing sunglasses during your morning sunlight routine can impact the effectiveness of the light exposure. According to Andrew Huberman, it's best not to wear sunglasses when you're attempting to get morning sunlight exposure right after waking. This helps in optimally triggering a set of neurons that send signals throughout your body, influencing wakefulness and setting your body's internal clock for better sleep timing later 1.

Thus, removing your sunglasses during this time allows more light to reach the melanopsin cells in your eyes, which are crucial for this physiological process. Even on days when the sun isn't fully visible due to cloud cover, the intensity of light is still beneficial for these neural mechanisms. Therefore, try to get direct sunlight without sunglasses for about the first hour after waking for optimal effect.
