Tuesday Roddle is Back!

Ok, some of you have heard this before so no guessing! But you are certainly welcome to reply or throw off the others. lol. This one’s a thinker so questions are welcome:

There’s a dead man lying in the middle of the desert face down with a straw in his hand. There is a pile of clothes next to him. How did he die?

ROD EDIT: the dude is also naked (thank you robert)
