However , if the sun is a little bit brighter and a little bit higher in the sky , sometimes it could be painful to look at . So the way to get this sunlight viewing early in the day is to look toward the sun . If it's too bright to look at directly , well , then don't do that .
There's so many different wavelengths of light coming from the sun and they are bright enough that they will trigger the mechanisms that you want triggered at this early time of day . So try and get outside ideally within the first five minutes of waking or maybe it's 15 minutes , but certainly within the first hour after waking , I wanna share with you three critical things about this tool of morning sunlight viewing . First of all , this is not some wu biology thing .
If your goal is to be awake , if you wake up at four in the morning and you need to be awake , well , then turn on artificial lights once the sun is out . However , once the sun has risen , then you still want to get outside and view sunlight . Some of you will wake up before the sun comes out .
This is grounded in the core of our physiology . There are literally hundreds if not thousands of quality peer reviewed papers showing that light viewing early in the day is the most powerful stimulus for wakefulness throughout the day . And it has a powerful positive impact on your ability to fall and stay asleep at night .
So the sun is just peeking through the clouds or it's more dense cloud cover . You want to get about 10 minutes of sunlight exposure to your eyes early in the day and on days that are really densely overcast or maybe even a rainy , you're going to want to get as much as 20 or 30 minutes of sunlight exposure . Another key thing is do not forget about , just don't try and get this sunlight exposure through a windshield of a car or a window , whether or not it's tinted or otherwise , it takes far too long .
