Is it normal to feel cold all the time when working a sedentary desk job all day?

Short answer

Why people ask this

Because they sit for hours at a computer, people want to know if desk-bound routines and office AC explain feeling cold. They also wonder when workplace factors stop being the cause and a health concern starts. Sedentary work reduces heat production from muscles, and open-plan offices are often kept cooler. But if cold sensitivity persists outside work or comes with other symptoms, it may need medical evaluation.

When it might be safe

• Feeling chilly mainly while sitting for long stretches under strong office AC or near vents
• Cold hands and feet that improve after short movement breaks or a warm drink at your desk
• Afternoon chills on days you’ve been sedentary, under-fueled, or dehydrated during back-to-back meetings
• Mild cold sensation that resolves when you leave the office or wear layers appropriate for your workstation
• Coldness that tracks with ergonomic factors (e.g., metal desk surfaces or a drafty window by your cubicle)

When it is not safe

• Feeling cold all the time, including at home or overnight, not just at your workstation
• Cold sensitivity with fatigue, hair loss, constipation, weight changes, or low mood (possible thyroid or hormonal issues)
• Pale or bluish fingers/toes, numbness, or pain with cold exposure (possible circulation or Raynaud’s)
• Chills with fever, night sweats, or unexplained weight loss
• Shortness of breath, chest palpitations, or dizziness along with feeling cold (possible anemia or heart issues)

Possible risks

• Reduced heat production from prolonged sitting—minimal muscle activity lowers thermogenesis during desk work
• Office climate factors: strong air conditioning, drafts near vents, or shared thermostat settings in open-plan spaces
• Undereating at the desk (skipping meals, low protein) or dehydration and high caffeine, which can worsen cold sensitivity
• Circulatory constraints from posture, tight clothing, or crossed legs while seated for long periods
• Medical contributors such as iron-deficiency anemia, hypothyroidism, low B12, low body fat, certain medications, or low blood sugar
• Poor sleep and stress from high workload, which can affect temperature perception and energy

Safer alternatives

• Schedule movement: 2–5 minute walks or stair laps every 30–60 minutes; try a sit–stand desk cycle (e.g., 20–8–2 rule: sit–stand–move)
• Optimize your workstation: layer clothing, warm socks, fingerless gloves; relocate from direct AC drafts; use an approved foot warmer if policy allows
• Support metabolism: regular balanced meals with protein and complex carbs; sip warm fluids; moderate caffeine and stay hydrated
• Improve circulation: uncross legs, do ankle pumps and hand squeezes, gentle desk stretches, and brief posture resets
• Check the environment: request HVAC adjustments, add a draft blocker near windows, or use a lap blanket in colder zones
• Screen if symptoms persist: ask your clinician about CBC/iron studies, TSH, B12, and glucose; review medications and discuss cold intolerance

Bottom line

It depends: many desk workers feel cold due to inactivity and office AC, and simple movement, layering, and fueling often help. If the cold is constant, severe, or comes with other symptoms, consider a medical evaluation to rule out anemia, thyroid issues, or circulation problems.
