What are some of the ... things that are emitted from the sun?
I want to know which of those we, as humans, are susceptible to.

For instance, when I sit out in the sun,
what am I absorbing, what am I reflecting? What is passing through me?

The sun emits radiation on a very wide range of wavelengths, but the atmosphere blocks certain wavelengths so we only get the visible light and small amounts of other stuff.

The sun also lets out the solar wind that is a constant stream of particles, the earths magnetic field prevents these from getting down to us.

Neutrinos from the fission of hydrogen in the suns core are passing through you, at every moment

What wavelengths reach us?

you might like a quick trip to Electromagnetic Energy on the web...

this is measured by wavelengths and frequencies and much of it reaches the earth. not only from our sun but many sources.

i remember hearing somewhere that we aquire vitamin D from sunlight. i dont know if the source is credable however.

this is the proverbial double edged sword; our body when hit with ultra violate rays, will produce Vit-D. UVR however is also the bad rays which gets through or not stopped by ozone. ie, we produce and not sent by the sun...

I've always loved this fact, and I've heard multiple facts similar to this, but here's what wikipedia has to say:

"Most neutrinos which pass through the Earth emanate from the sun and more than 50 trillion solar electron neutrinos pass through the human body every second."

ooooh. thats interesting...

Funny enough, at midnight, with the sun on the other side of the world, the same number of sun-generated neutrinos pass through you as at noon! It passes straight through Earth as if there was nothing!

thats really cool too. i remember reading in a book that there was a chemical called melatonin that your body can only produce at night. i suppose that this has nothing to do with UVR's then. can any one tell me a bit more about them?
