What is the first sign of dehydration?

The first symptom of dehydration should be thirst but as we have noted above this response is often blunted. Symptoms generally progress to more dire manifestations as the need for water becomes more extreme. Someone who is chronically dehydrated at a point somewhere between normal and the mild dehydration we discuss below may even be able to develop a tolerance for that state so that it becomes the "new normal" for them. Suffice to say that any level of dehydration will lead to long term consequences if left unaddressed.

There are some symptoms for dehydration:

Thirst

Reduced Appetite,

Skin Flushing

Dark colored Urine

Dry Mouth

Fatigue

Mild headache

Chills

Dizziness
