Feeling Cold With A Cold Understanding Why It Happens

It’s a familiar scenario: you start sneezing, your throat feels scratchy, and suddenly, despite being under two blankets, you’re shivering. You don’t have snow outside or an overactive air conditioner—yet you feel freezing. This paradox—feeling cold while fighting off a cold—is more than just discomfort; it’s your body responding in a specific, biologically meaningful way. Understanding why this happens can help you respond more effectively, reduce suffering, and support recovery.

The Biology of Feeling Cold During a Cold

When a virus like rhinovirus (the most common cause of the common cold) enters your body, your immune system immediately goes on high alert. One of the first responses is the release of signaling proteins called cytokines. These molecules coordinate the immune defense but also influence the hypothalamus—the brain’s thermostat.

The hypothalamus responds by raising your body’s internal temperature set point, initiating a fever. However, until your body temperature actually rises to meet this new set point, you experience chills and a sensation of coldness. This mismatch between your current temperature and the desired higher one triggers shivering, vasoconstriction (narrowing of blood vessels), and behavioral changes like pulling on extra layers—all attempts to generate and conserve heat.

“Chills during a cold are not a sign that you’re too cold—they’re a sign your body is actively fighting infection.” — Dr. Lena Patel, Immunologist at Boston General Hospital

How Fever and Chills Are Connected

Fever is a protective mechanism. Elevated body temperature can inhibit viral replication and enhance immune cell activity. But the process of getting to that elevated temperature often involves feeling cold—even if your skin feels warm to the touch.

During the onset of a fever, your core temperature may still be normal or only slightly elevated, but because your brain has reset its target, everything below that feels “too cold.” This explains why someone with a low-grade fever might still bundle up despite sweating moments later once the fever peaks.

Tip: Don’t suppress early chills with heavy heating or excessive bundling—moderate warmth helps your body regulate temperature without overheating later.

Common Triggers That Worsen the Sensation of Cold

While chills are part of the immune process, certain factors can intensify the feeling of coldness during a cold:

• Dehydration: Reduced fluid levels impair circulation and thermoregulation, making you more sensitive to temperature drops.
• Low energy intake: When you’re not eating well due to illness, your body produces less heat.
• Inadequate rest: Sleep deprivation weakens immune efficiency and disrupts temperature control.
• Medications: Some decongestants or antihistamines can affect blood flow and perception of temperature.

Addressing these underlying issues can reduce unnecessary discomfort and support faster recovery.

Practical Steps to Manage Cold Sensations While Sick

Feeling cold is normal when you have a cold, but that doesn’t mean you should endure it passively. Strategic care can ease symptoms and create conditions for healing.

Step-by-Step Guide to Comfortable Recovery

1. Monitor your temperature: Use a thermometer to distinguish between actual fever and perceived coldness. This prevents overuse of fever reducers unless necessary.
2. Dress in layers: Wear lightweight, breathable fabrics that can be added or removed as your temperature fluctuates.
3. Stay hydrated: Drink warm fluids like herbal tea, broth, or water with lemon. Hydration supports circulation and helps regulate body temperature.
4. Maintain room temperature: Keep your environment between 68–72°F (20–22°C)—warm enough to prevent shivering, cool enough to avoid overheating.
5. Eat small, nourishing meals: Even if appetite is low, consuming foods rich in vitamins C and zinc supports immune function and energy production.
6. Prioritize sleep: Aim for 8–10 hours per night in a quiet, dark room to optimize immune activity.

Do’s and Don’ts: Managing Cold Sensations

Do’s	Don’ts
Use a humidifier to keep air moist and breathing easier	Overbundle or use electric blankets on high settings
Sip warm liquids throughout the day	Ignore signs of dehydration like dry mouth or dizziness
Rest even if you don’t feel extremely ill	Push through symptoms with strenuous activity
Take acetaminophen or ibuprofen if fever exceeds 101.5°F (38.6°C)	Rely solely on medication to mask symptoms without addressing root causes

Real Example: How Sarah Managed Her Cold-Induced Chills

Sarah, a 34-year-old teacher, woke up with a runny nose and fatigue. By midday, she was shivering under her duvet despite it being 70°F indoors. She initially thought she’d caught hypothermia from leaving a window open, but a quick temperature check revealed a fever of 100.8°F.

Instead of cranking up the heat, she layered cotton pajamas with a light fleece blanket, drank ginger-lemon tea, and rested. Within six hours, her fever peaked at 101.4°F, then gradually subsided. By the next morning, her chills were gone, and she felt significantly better. Her proactive approach prevented dehydration and avoided temperature swings caused by over-bundling.

Sarah’s experience illustrates how recognizing chills as a symptom—not a standalone issue—can lead to smarter self-care decisions.

When to Seek Medical Attention

While feeling cold during a cold is typical, certain red flags suggest complications:

• Fever above 103°F (39.4°C) lasting more than 48 hours
• Confusion, stiff neck, or sensitivity to light (possible signs of meningitis)
• Difficulty breathing or chest pain
• Prolonged chills without fever (could indicate bacterial infection or other conditions)

If you experience any of these, consult a healthcare provider promptly. Persistent cold sensations without clear viral symptoms may also relate to thyroid dysfunction, anemia, or poor circulation—conditions worth investigating if they recur frequently.

Frequently Asked Questions

Can you have chills without a fever?

Yes. Early in infection, your body may initiate heat-conserving behaviors before a measurable fever develops. Additionally, some people—especially older adults—may not mount a strong fever response despite infection, yet still feel cold due to immune signaling.

Why do I feel cold even after my cold is gone?

Post-viral fatigue can linger for days or weeks. During recovery, your body may still be adjusting its metabolic rate and circulation. Nutritional deficits or stress from illness can also temporarily alter temperature regulation.

Is it bad to take fever-reducing medicine right away?

Not necessarily, but it depends on severity. Mild fevers (under 101.5°F) are beneficial and usually don’t require treatment. Suppressing them too early may prolong illness. Use medication primarily for comfort when symptoms interfere with rest or hydration.

Conclusion: Listen to Your Body’s Signals

Feeling cold with a cold isn’t a glitch—it’s a calculated move by your immune system to gain the upper hand against invading viruses. By understanding the physiology behind chills and fever, you can respond with informed care rather than fear or frustration. Support your body with hydration, rest, and balanced warmth, and you’ll likely recover more comfortably and efficiently.
