How to stay warm at work in a cold office
To stay warm in a cold office, add a thin base layer under your work clothes, keep a vest or cardigan at your desk, and wear warm socks and closed shoes. Warm your hands with a hot drink, take short walking breaks, and move away from vents. If you want a space heater, check your workplace rules first, and raise persistent cold with facilities.
Why are offices so cold?
Office thermostats are usually set for the average occupant, and the averages behind common comfort models may not fit everyone. In a 2015 paper in Nature Climate Change, Boris Kingma and Wouter van Marken Lichtenbelt noted that indoor climate standards rest on a thermal comfort model developed in the 1960s, with metabolic rate values based on an average male. They wrote that these values may overestimate female metabolic rate by up to 35%.
Their accompanying measurements involved a small group of 16 young women doing light office work, whose metabolic rates were about 20 to 32 percent lower than typical design values, as Phys.org reported. The researchers themselves noted the sample was small. The broader point holds: people differ in how much heat they produce at a desk, so a single setpoint leaves some people cold.
Other causes are simpler: supply vents blowing on a desk, a seat next to a cold window, and hours of sitting still. Working from home brings its own version: a thermostat set low to save money and a desk in the coldest room of the house.
What temperature should an office be?
In the United States there is no federal rule. OSHA has stated that office temperature and humidity are matters of human comfort and that it has no regulations specifically addressing them. OSHA does recommend temperature control in the range of 68 to 76°F and humidity of 20 to 60 percent.
That range is wide. Someone sitting still in light clothing near the bottom of it can feel cold even though the building is within guidance.
What can you wear to stay warm at a desk?
Layering works indoors just as it does outdoors, and discreet layers are the most useful at work:
A thin merino or synthetic base layer under a shirt or blouse adds warmth without bulk.
A vest, cardigan or light fleece kept at your desk warms the torso and comes off easily for meetings.
Wool socks and closed shoes, or a pair of warm slippers under the desk if your workplace allows.
A scarf or wrap for drafty areas, which is easy to add and remove.
Fingerless gloves for typing, if cold hands slow you down.
Is a heated or heat-reflective vest practical in an office?
A slim vest under a blazer or cardigan is one of the least visible ways to add core warmth, and a warm torso helps keep hands and feet comfortable. Battery-heated vests give adjustable heat but need charging. Non-electric options, such as HEATJAC REFLECT, a lightweight heat-reflective vest with warming pockets, work without a battery.
Keep any heating element off bare skin, turn heat down rather than letting yourself sweat, and follow the maker's instructions.
How do you warm your hands and feet at work?
Hold a hot drink, run warm water over your hands at the sink, and stand up to walk for a few minutes each hour. Movement raises the body's heat production, and a short walk to refill water or take a call helps more than you might expect.
Keep feet off cold floors with a small rug or a footrest, and move your desk or chair away from supply vents if you can. If your fingers or toes turn white or blue, go numb, or you feel cold when others are comfortable, talk to a clinician, since persistent cold intolerance has medical causes worth checking.
Can you use a space heater at work?
Check first. Many workplaces restrict personal heaters because of electrical load and fire risk. If yours allows one, the U.S. Fire Administration advises keeping anything that can burn at least 3 feet from heat sources, including space heaters, and turning heaters off when you leave the room.
Practical additions: choose a unit with tip-over and overheat protection, plug it directly into a wall outlet rather than a power strip, and never leave it running under a desk full of paper. A heated footrest or a desk-level warmer uses far less power than a full space heater.
How do you ask for a warmer workspace?
Be specific. Tell facilities where you sit, when it is coldest, and whether a vent blows on you. Small fixes such as adjusting or redirecting a diffuser, moving your desk, or rebalancing a zone often solve the problem without changing the whole building.
If several people are affected, a shared request carries more weight. Keep the conversation about comfort and productivity, and remember that the person next to you may genuinely be warm at the same setting.
Key takeaways
Common comfort models were built around an average male metabolic rate, so many people feel cold at standard settings.
OSHA recommends 68 to 76°F for offices but has no binding office temperature rule.
Discreet layers, especially a vest or base layer, add core warmth without bulk.
Move regularly, warm your hands, and get your feet off cold floors.
Check workplace rules before using a space heater and keep it 3 feet from anything that can burn.
Frequently asked questions
Why am I always cold at work when others are not?
People produce different amounts of body heat and have different body sizes and clothing, so the same setting feels different to each person. Sitting still, drafts and cold windows add to it. If you feel cold much more than others in many settings, talk to a clinician.
How can I stay warm at work without a space heater?
Wear a thin base layer, keep a vest or cardigan at your desk, wear wool socks, drink warm beverages and take short walking breaks. A footrest or rug keeps feet off a cold floor.
Is there a legal minimum office temperature in the US?
No federal minimum exists for offices. OSHA recommends 68 to 76°F and 20 to 60 percent humidity but has said it has no regulations specifically addressing office temperature.
What should I wear to a cold office?
Layers you can adjust: a thin base layer under your clothes, a vest or cardigan, closed shoes with warm socks, and a scarf for drafty areas.
Are heated vests appropriate for office wear?
A slim vest worn under a blazer or cardigan is usually unnoticeable. Choose one that fits close to the body, keep heat settings low enough that you do not sweat, and follow the maker's instructions.
