Chills are your body’s way of generating heat through rapid, involuntary muscle contractions. Stopping them depends on what’s causing them: a fever, cold exposure, anxiety, or something else entirely. In most cases, you can get relief at home within 15 to 30 minutes using the right approach for your situation.
Why Your Body Shivers
A region at the front of your brain called the preoptic area acts as your internal thermostat. It constantly receives temperature readings from sensors in your skin and throughout your body. When it decides you need more heat, whether because you’re actually cold or because an infection has raised your body’s target temperature, it sends signals down through the brainstem and spinal cord that hijack your skeletal muscles. The result is shivering: a rapid, involuntary contraction pattern designed purely to burn energy and produce warmth.
This is the same motor system you use for voluntary movement, but during chills, your thermostat overrides your conscious control. That’s why you can’t simply will yourself to stop shaking. You have to address the underlying trigger.
Stopping Fever-Related Chills
Fever chills feel counterintuitive. Your body temperature is elevated, yet you feel freezing. That’s because the infection has essentially turned up your thermostat’s set point. Your brain now treats your normal temperature as “too cold” and triggers shivering to close the gap. The key to stopping these chills is lowering the fever itself, not piling on warmth.
Over-the-counter pain relievers like acetaminophen (Tylenol) or ibuprofen (Advil, Motrin) work by bringing your thermostat’s set point back down. Follow the dosing instructions on the label. Most people notice improvement within 30 to 60 minutes as the fever drops and the brain stops demanding extra heat.
While you wait for the medication to kick in:
- Stick to one light layer of clothing. It feels natural to bundle up, but heavy blankets and layers trap heat and can push your fever higher.
- Skip hot baths or showers. These can worsen the fever. A lukewarm bath is a better option if you want water-based comfort.
- Drink fluids steadily. Dehydration impairs your body’s ability to regulate temperature. Even mild fluid loss reduces blood volume and makes it harder for your cardiovascular system to distribute heat evenly. Water, broth, and warm (not hot) drinks all help.
Managing Chills in Children
Children get chills from fevers frequently, and the approach is similar to adults with a few important differences. Acetaminophen and ibuprofen are both safe for children when dosed correctly for their weight and age, with ibuprofen appropriate for kids six months and older. Never give aspirin to a child or teenager. It’s linked to Reye syndrome, a rare but serious condition affecting the brain and liver.
Dress your child in lightweight clothing and cover them with a light sheet or blanket rather than heavy bedding. Offer plenty of liquids throughout the day. If your child is also vomiting or has diarrhea, an oral rehydration solution can help replace lost electrolytes more effectively than water alone. Never use rubbing alcohol or cold baths to bring a fever down, as both can cause dangerous drops in body temperature or skin irritation. Let your child rest and eat what appeals to them without forcing meals.
Chills From Cold Exposure
When chills come from genuinely being cold rather than from illness, the fix is straightforward: warm up. But how you warm up matters, especially if you’ve been exposed to cold for a prolonged period.
Focus warmth on the center of your body first. Apply warm, dry compresses to your neck, chest, and groin, where large blood vessels sit close to the surface. An electric blanket works well if you have one. If you’re using a hot water bottle or chemical heat pack, wrap it in a towel before placing it against skin to prevent burns. Drink something warm and sweet, like hot chocolate or sweetened tea.
A few things to avoid: don’t rewarm too quickly with a heating lamp or hot bath, as rapid rewarming can stress the heart. Don’t try to warm the arms and legs first, since heating the extremities before the core can push cold blood back toward the heart and lungs. And don’t drink alcohol. Despite its reputation as a warming agent, alcohol actually hinders the rewarming process by dilating blood vessels near the skin and accelerating heat loss.
Anxiety and Stress Chills
Chills don’t always involve temperature at all. During a panic attack or period of intense stress, your body floods with adrenaline, which can trigger shivering, goosebumps, and a sensation of cold. The muscles tense, blood flow shifts, and your nervous system behaves as though you’re under physical threat.
The fastest way to interrupt this cycle is controlled breathing. Breathe in for four seconds, hold for four seconds, and exhale for four seconds. This rhythm activates the parasympathetic nervous system, the branch responsible for calming you down, and directly counteracts the adrenaline surge driving the chills. Repeat for two to three minutes or until the shaking subsides.
Other techniques that help in the moment include visualization (picturing a calm, detailed scene), mindfulness meditation (anchoring your attention to what you can see, hear, or feel right now), and gentle movement like yoga poses or stretching. These all work by shifting your nervous system out of fight-or-flight mode. If anxiety chills happen regularly, that pattern is worth exploring with a mental health professional, since it usually responds well to treatment.
Post-Surgery Shivering
Shivering after general anesthesia is common, affecting roughly 6 to 14 percent of surgical patients. It happens because anesthesia disrupts your body’s temperature regulation, and operating rooms are kept cool. Your body often emerges from sedation already below its target temperature and shivers aggressively to compensate.
This type of shivering is typically managed by the medical team in the recovery room with warming blankets and, when needed, medications. It usually resolves within 20 to 45 minutes. If you’re heading into surgery and you’ve experienced post-anesthesia shivering before, let your anesthesiologist know so they can take preventive steps.
When Chills Signal Something Serious
Most chills resolve on their own or with basic home care. But chills combined with certain other symptoms can indicate a serious infection or sepsis, a life-threatening immune response. Seek emergency care if chills are accompanied by confusion, rapid breathing, a fever that won’t respond to medication, or signs of an infection that’s getting worse rather than better. Chills with a stiff neck, severe headache, or a rash that doesn’t fade when pressed also warrant immediate attention.
For otherwise healthy adults, isolated chills from a mild fever or brief cold exposure are rarely dangerous. But chills that persist for hours, keep returning without a clear cause, or come with progressively worsening symptoms deserve a medical evaluation sooner rather than later.
