Answer 2

Your body can be sensitive to change such as a light raction. The sneeze is your body getting used to the sun and its completly natural.

Answer 3

Dust allergy.

Answer 4

It could be due to allergies.

But Miko might have it nailed.  I "suffer" from ACHOO syndrome, myself.  It can be triggered by the Sun, or even just looking at a bright light.  Fortunately, I don't have it "bad," as usually it's just a sneeze and I'm done.  I understand some people can go on, and on, and .....you get the picture.

Answer 5

it is because your allergy's are acting up
