When I went to Stok Kangri trek, while climbing down from the peak, on the snow-filled slopes, I felt terribly dehydrated. I was having ample amount of water throughout the climb and yet, I felt dehydrated on the snow-filled slopes. However, once I was out of the snowy slopes on to the solid land, this feeling of dehydration went off.
Hence, my question is: is there a possible scientific explanation to the feeling of dehydration? i.e, if one is surrounded by snow, can the body end up losing water through the pores of the skin leading to a feeling of dehydration?
P.S.: I am NOT referring to eating of snow in place of drinking water. I am asking about a possible threat of dehydration when in a snowfall area.
EDIT: Solid land refers to slopes with no snow. It doesn't mean the end of efforts or an easier track. There was absolutely no difference in the gradient of the slope or the difficulties involved. The effort was made on the same day and it was as good as flipping a switch once I left the snowy slopes (the feeling of dehydration went off in a matter of minutes).
