Why you’re always cold
Being the one in the sweater when everyone else is fine usually has an ordinary explanation; here are the common ones, what to try, and when to call the doctor.
Somebody in every house is always cold. They have the cardigan on in July. Their hands feel like they came out of the refrigerator, and they would like you to stop remarking on it.
If that is you, and it seems to have gotten worse as the years add up, there is usually a plain reason. Here are the ordinary explanations, what you can try at home, and the handful of signs that mean it is time to see a doctor instead of buying another blanket. I am not a doctor, so take this as a map, not a diagnosis.
The ordinary reasons
Less muscle. Muscle is where your body makes a lot of its heat, and most people lose some of it every decade after 40 unless they work to keep it. Less muscle means a smaller furnace. It is the most common reason of all.
Being thinner. Body fat is insulation. People who are naturally slim, or who have lost weight on purpose, feel the cold more. That is just physics.
Thyroid. The thyroid gland sets your metabolic idle speed. When it runs slow, which is more common in women and more common with age, feeling cold is one of the classic signs, usually alongside tiredness, dry skin, and weight that creeps up for no reason. It shows up on a simple blood test, and a doctor can usually manage it.
Iron. Low iron means fewer red blood cells carrying oxygen around, and one of the ways that shows up is cold hands and feet, plus fatigue and sometimes a paler face than usual. Women who are still menstruating, people on restrictive diets, and anyone with stomach or gut trouble are more likely to run low.
Circulation. As the years add up, blood vessels get a little less flexible, and the small ones in the hands and feet are the first to feel it. Some people also have a condition where the fingers go white or blue in the cold and then flush red as they warm. That one is worth mentioning to a doctor, though it is often harmless on its own.
Medications. Some blood pressure medicines, especially beta blockers, reduce blood flow to the hands and feet as a side effect. If the cold started around the time a prescription did, that is worth a conversation with whoever prescribed it. Do not stop taking anything on your own.
Not eating enough. Skipping meals, or living on toast and tea, gives the body less fuel to burn. A lot of people who are cold all winter are also skipping breakfast or lunch.
What to try at home first
- Eat something warm with protein in the morning. Eggs, oatmeal with nuts, last night’s leftovers. Give the furnace fuel.
- Move for ten minutes when you feel the chill. A walk around the block or a few trips up the stairs warms you faster than a blanket does.
- Build a little muscle. Two short sessions a week with light weights or resistance bands is enough to make a difference over a few months.
- Cover the neck, wrists, and ankles. Those are where blood runs close to the skin. A scarf and wool socks do more than a second sweater.
- Drink enough water. Mild dehydration makes it harder to regulate temperature, and most people past 45 drink less than they think.
- Ask for an iron and thyroid check the next time you are having blood drawn anyway. Both are routine.
Signs that mean a doctor visit
Cold on its own, with nothing else going on, is usually just cold. It is the company it keeps that matters. Make an appointment if the chill comes with any of these: tiredness that does not lift with sleep, unexplained weight gain or loss, hair thinning, fingers that change color, shortness of breath on the stairs, a racing or skipping heartbeat, or numbness and tingling in the feet.
And go sooner if one side of the body is colder than the other, if a foot or leg is cold and pale and painful, or if the cold came on suddenly rather than over months. Those are not wait-and-see situations.
The warm-house tricks that cost nothing
You do not have to heat the whole house to stop being cold in it. Heat the person.
Put a rug down where your feet spend the most time; a bare floor pulls heat out of you all day. Close the doors to rooms nobody is using so the furnace is not paying to warm the guest room. Open the curtains on the sunny side of the house in the morning and close them all at dusk; a window is a hole in the wall as far as heat is concerned.
Fold the laundry while it is still warm from the dryer; it sounds ridiculous and it works. A heating pad on the lap for twenty minutes does more than turning the thermostat up three degrees, and it costs pennies.
And switch the ceiling fan to run clockwise on low in the winter. It pushes the warm air sitting at the ceiling back down to where you are. Most people never flip the switch.
Being the cold one is annoying, not shameful, and most of the time it is fixable with food, movement, a scarf, and one blood test. The sweater can stay. The guilt can go.
