Can anyone interpret the ending of this poem by Phillis Wheatley?

As I'm sure you can tell, this is a poem praising the beauty of the early morning -- the singing of birds, the many colors of dawn in the eastern sky, etc. It ends with the sun appearing over the horizon and the speaker of the poem exclaiming that the sun's rays are too hot and/or too bright. She has to stop praising nature's beauty, presumably because she has to seek shelter from the sun.
