What Does It Mean if You Get Chills?
You’re lying still, wrapped in a blanket, and suddenly you’re shivering. No fever, no cold breeze. Just that unmistakable shiver running down your back. What does it mean to have chills with no obvious cause? While it may seem harmless, your body could be sending you subtle signals that you shouldn’t ignore.
TL;DR
Chills can occur with or without a fever and are often linked to infections, cold exposure, stress, or emotional triggers. While they are usually harmless, persistent or unexplained chills may indicate underlying issues like infections, hypothyroidism, or malnutrition. Managing chills includes hydration, rest, warmth, and over-the-counter medications. Seek medical help if chills are severe, ongoing, or accompanied by symptoms like high fever, pain, or confusion.

Why Do I Have the Chills?
Chills can be caused by cold, illness, or intense emotional reactions. In the case of illness, they often appear early in an infection and can also signal underlying health issues. Even without a fever, someone may feel chills if their body isn’t regulating temperature properly, which may require a medical check-up.
Chills are closely linked to the autonomic nervous system and to stress or fear. The body responds with a fight-or-flight reaction, releasing adrenaline and directing energy toward muscles, which can create a vibrating or tingling sensation across the skin. This doesn’t always indicate real danger, but it does show that the body is alert.
Chills can also appear in non-threatening situations, like when hearing emotionally intense music or seeing someone you find attractive. In these cases, the chill is a positive sensory response. Some people are simply more sensitive to cold, without it being a health issue. If chills are frequent or unexplained, it’s a good idea to see a doctor to rule out medical causes.

Health Conditions That Cause Chills
Chills aren’t always triggered by cold weather. They can also signal that something is wrong in the body. Several health conditions can cause this response, and knowing the source can help guide proper treatment.
When You Get Chills What Does That Mean?
When you get chills, it usually means your body is responding to internal or external changes—such as infection, cold exposure, dehydration, or even strong emotional reactions. This reaction is often the body’s way of regulating temperature and protecting vital functions.
One of the most common causes of chills is infection—bacterial (pneumonia, urinary tract infections, typhoid fever, listeria, hantavirus), viral (flu, common cold, mononucleosis, RSV, COVID-19), or parasitic (giardiasis, malaria). These conditions can cause fever, inflammation, and general discomfort, with chills appearing as an early or accompanying symptom.
These infections may also include abdominal pain or fatigue, depending on the body system affected.
Chills may be related to many health conditions. Identifying the cause can help guide treatment, so it’s recommended to seek medical care if chills are persistent, intense, or unexplained.
Chills Symptoms
When talking about a chill symptoms, it’s important to understand that chills are not just about feeling cold—they are often part of a larger physical reaction. Depending on the cause, chills can appear with a variety of accompanying signs, such as:
- Shivering or trembling even when the environment is warm.
- Goosebumps on the skin as muscles tighten around hair follicles.
- Muscle tension or stiffness during the episode.
- Fatigue or weakness that follows the chills.
- Mild fever or feeling feverish without a confirmed temperature spike.
- Headaches or body aches as part of the body’s inflammatory response.
- Sweating after chills pass, as the body releases heat.
These symptoms can be mild and temporary, especially if caused by environmental changes or emotional triggers. However, when chills are frequent, intense, or occur with other concerning signs like high fever, severe pain, or confusion, they may point to an underlying medical condition that requires attention.
Chills Without Fever
Feeling chills without a fever is common and often not a serious issue. Chills are a natural way for the body to produce heat when it senses a temperature drop or a disruption in internal balance. This response helps protect vital organs like the brain and heart.
Chills without fever can have various non-serious causes, including:
- Cold exposure: Even a slight breeze or cool room can cause chills in sensitive individuals.
- Dehydration: Low fluid levels can interfere with temperature regulation.
- Intense exercise: The body can react with temperature shifts after physical activity.
- Medication side effects: Some drugs can affect the nervous system or hormone levels.
- Emotional stress: Stress, anxiety, or fear can trigger physical responses like chills.
Related Medical Conditions
Some health problems can cause chills even without a fever:
| Hypothyroidism | Slows metabolism, increasing sensitivity to cold. |
| Hypoglycemia | Low blood sugar can lead to shivering and chills. |
| Malnutrition | A lack of nutrients limits energy and heat production. |
Infections Without Fever
You can have an active infection without visible fever, especially early on. Infections that may cause chills without fever include:
- Bronchitis
- Food poisoning
- Stomach virus
- Skin infections (cellulitis or abscesses)
When to Be Concerned
If chills are persistent, intense, or occur alongside other symptoms like pain, severe fatigue, or changes in appetite, a full medical evaluation is recommended.
How to Get Rid of Chills?
Chills are the body’s way of trying to regulate internal temperature. While this is a natural process, there are effective ways to ease chills and feel better. Here are some practical strategies you can try at home. If symptoms persist or worsen, consult a healthcare provider.
What to Do When You Have the Chills
General Recommendations:
- Stay hydrated: Drink plenty of fluids and monitor urine output. Dehydration can make chills worse.
- Get enough rest: Rest helps your body recover and conserve energy.
- Avoid temperature extremes: Don’t bundle up if you have a fever, and avoid fans or air conditioning. These can make chills worse.
- Take a warm sponge bath: This helps regulate your body temperature gently without shocking the system.
Common Medications
Over-the-counter medications can help relieve fever and chills:
| Acetaminophen | Lowers fever and helps relieve chills. |
| Aspirin | Reduces body temperature and discomfort. |
| Ibuprofen | Works as an anti-inflammatory and pain reliever. |
Always follow the instructions on the label or consult a healthcare provider if you have existing conditions.
Natural Remedies
Some herbal teas and home remedies can offer gentle relief:
| Infusion | Benefit |
| Cinnamon | Helps regulate body temperature. |
| Black pepper | Warms the body from within. |
| Ginger | Boosts energy and improves circulation. |
These drinks can be enjoyed warm throughout the day, as long as there are no contraindications.
When to Seek Medical Help for Chills
Chills can be a normal reaction to mild fever or cold, but in some cases, they point to a more serious medical issue.
See a doctor if chills show any of the following signs:
- Persistent or intense chills that don’t improve with rest or warmth.
- Other severe symptoms, such as high fever, abdominal pain, or trouble breathing.
- Neck stiffness, confusion, drowsiness, or light sensitivity.
- High fever above 103°F (39.4°C) in adults or above 101°F (38.3°C) in infants younger than 3 months.
- Strong cough, painful urination, or repeated vomiting.
- Rash or signs of dehydration, like excessive thirst or dizziness.
Urgent Cases
- Suspected hypothermia, especially with pale skin, confusion, or severe drowsiness.
- Chills with vomiting or severe diarrhea, which may indicate serious infection or food poisoning.
Chills are not always cause for concern, but if they persist or appear with other troubling symptoms, medical attention can prevent complications. Paying attention and acting early can make all the difference in recovery.
