When most people think of dehydration, they picture classic symptoms like thirst, dry mouth, or fatigue. But chills? That’s one you might not expect, and yet, dehydration can cause chills in certain situations. If you’ve been sweating in the heat or haven’t had enough fluids, and you suddenly feel cold or shivery, your body may be trying to warn you that it’s in distress. In this blog, we’ll explain why dehydration causes chills, what other symptoms to watch for, and when it’s time to see a medical provider.

Understanding Dehydration
Dehydration occurs when your body loses more fluid than it takes in. This can happen due to:
- Excessive sweating (from heat or exercise)
- Illness (vomiting, diarrhea, or fever)
- Not drinking enough water throughout the day
- Certain medications or medical concerns
Water is essential for regulating body temperature, maintaining blood pressure, and supporting vital organ function. When fluid levels drop too low, your body can struggle to regulate heat, which may trigger symptoms like dizziness, confusion, or even chills.
How Can Dehydration Cause Chills?
There are a few reasons why you might feel cold or shivery when you’re dehydrated:
1. Impaired Temperature Regulation
Your body uses sweat to cool down and blood flow to warm up. When you’re dehydrated, these systems don’t work as efficiently. If your temperature regulation is off, you may feel cold even if you’re in a warm environment.
2. Drop in Blood Pressure
Dehydration reduces blood volume, which can cause your blood pressure to fall. Low blood pressure may lead to poor circulation– and that lack of blood flow to your skin and extremities can make you feel cold or develop chills.
3. Heat Exhaustion or Heat Illness
In hot conditions, dehydration can contribute to heat exhaustion or even heatstroke. Chills may occur as your body begins to overheat and fail to cool down properly, especially if you’ve been in the sun or working out.
4. Fever-Related Dehydration
If you’re sick and running a fever, your body loses fluid faster than sweat and respiration. Chills may occur as your internal temperature fluctuates during a fever, especially if you’re not rehydrating properly.
Other Symptoms To Watch For
If dehydration is the cause of your chills, you’ll likely notice other signs as well, such as:
- Dry mouth or lips
- Dark yellow urine or decreased urination
- Dizziness or lightheadedness
- Fatigue or confusion
- Headache
- Muscle cramps
How To Treat and Prevent Dehydration-Related Chills
It’s important to rehydrate slowly and consistently. Drink small sips of water or electrolyte-rich beverages, and avoid chugging large amounts all at once. If you’re overheated, move to a shaded or air-conditioned space. Use cool compresses or damp towels. Sit or lie down to allow your body to recover and avoid exerting yourself until your symptoms improve. If your symptoms worsen or don’t improve within a few hours, seek medical help. Prompt treatment can prevent complications and help you recover faster.
