The color and smell of bodily fluids can tell you a lot about your health. Talking about bodily fluids can be unpleasant, but they may be your body’s way of indicating that something isn’t right. Although bodily fluids aren’t a common topic of conversation, you should speak to your doctor if they seem off, as it may mean there’s something going on that needs to be addressed by a medical professional.
Mucus
Believe it or not, we produce and swallow about 2 cups of nasal mucus every day. While it sounds unappealing, nasal mucus serves an important purpose. It acts as a barrier to infection, trapping foreign particles so they don’t enter the body and infect your lungs.

The color of your mucus isn’t as important as whether it suddenly changes from what you’re used to seeing and how you feel otherwise. See a doctor if you have any concerning symptoms or don’t get better after a few days.
Urine
Clear or pale yellow urine is a good indicator that you are generally healthy and well-hydrated. But if you notice other colors, it may mean something isn’t quite right:
The smell of your urine can also indicate a health issue. Urine typically should not have much of an odor. If you smell something strong or sweet, it could be a sign of a urinary tract or bladder infection, diabetes, or other metabolic diseases. Some foods and medications (like asparagus) can affect the color and smell of urine. But if it’s happening on a regular basis and you don’t know why, mention it to your doctor.
Sweat
Our bodies produce two types of sweat: a light, watery sweat when we’re exercising and a thick, fatty sweat when we’re stressed. While some sweat is natural and helps to cool you off, there are certain instances when sweating (or not sweating) can indicate a problem:
A sudden outbreak of heavy sweating may also indicate a serious health issue, such as a heart attack. If this occurs, especially if accompanied by other symptoms, seek medical treatment right away.
