the senses are important still; but! Best if they are important to the story; or showing how much the person hates being in that situation. or to show the enemy needs a bath. etc. Now touch, sight, sound, smell, taste. All important; they help the reader be in the situation. There is, though, a thing as too much information. The most important questions to ask is "What is the character doing, and how are they feeling. As in; are they feeling cold from a breeze crossing through the woods? Are they scared being in that fog? Did they trip and land in bog muck? A good example about bad smell would be in that. Being covered in bog muck, it is a disgusting smell. So gnats might be attracted, and your character's mood sour because of being sticky, smelly and just downright uncomfortable. Annoyed at the bugs etc. ^0^
Hey, I hadn't thought of that before, showing environmental stuff like gnats being attracted to a character that smells bad. I'm trying to make sure I keep the mantra of 'show, not tell' when it comes to things that could be easily shown rather than say "You smell bad."
So, like you said, instead of someone saying "I'm cold!", it'd be better to show a cold wind going through the forest and the character shivering in tandem. Or, if someone's hot, them fanning themselves with their hands/something and also sweating, wiping their foreheads, etc.
Actually... now, this makes me want to compile a list of emotions and things people do that are associated with those things. Like sweating when nervous and etc.
