Feeling unusually cold a lot of the time can be totally normal for some people, but it can also be a signal from your body that something else is going on.

Quick Scoop: Why you might be “so cold”

Think of warmth like a team effort: blood flow, hormones, muscles, fat, and nutrition all play a role in keeping your body at a comfy temperature.

Common physical reasons

These are some of the most frequent causes doctors talk about when someone says “I’m always freezing”:

  1. Anemia (low red blood cells)
    • Your blood carries oxygen and heat; if you don’t have enough healthy red blood cells, less warmth gets around your body.
 * Other clues: tired all the time, dizzy, short of breath, pale or yellowish skin, fast heartbeat.
  1. Low thyroid (hypothyroidism)
    • Your thyroid helps control metabolism; when it’s underactive, your “internal furnace” runs on low, so you feel colder than others.
 * Often comes with weight gain, fatigue, dry skin, hair changes, constipation, feeling “slowed down.”
  1. Low body fat or low BMI
    • Body fat acts like built‑in insulation; if you’re very lean or underweight, it’s easier for heat to escape.
 * This can be from genetics, high activity, illness, or restrictive eating patterns.
  1. Circulation issues (blood flow problems)
    • Poor blood flow means less warm blood reaching hands and feet, making fingers and toes icy even when the room is fine.
 * Conditions like peripheral artery disease or Raynaud’s can do this, sometimes turning fingers pale or bluish in the cold.
  1. Hormones and sex differences
    • Estrogen can make you more sensitive to cold by changing blood flow and lowering body temperature.
 * People with more muscle mass tend to run warmer because muscle generates heat more easily.
  1. Not enough fuel or nutrients
    • Low vitamin B12, folate, or iron can cause certain types of anemia, which circles back to that cold feeling.
 * Very low calorie intake, eating disorders, or long‑term poor diet can also drop your core temperature.

When “just cold” might be more serious

You should get checked by a doctor or clinic soon (or talk to a nurse line) if being cold comes with things like:

  • Extreme fatigue or weakness
  • Dizziness, fainting, or shortness of breath
  • Chest pain, irregular or racing heartbeat
  • Noticeably pale, blue, or blotchy fingers/toes, especially in the cold
  • Unintentional weight loss or gain
  • Changes in periods, hair loss, or very dry skin

If this is new , getting worse, or feels different from your “normal,” it’s worth taking seriously and not just powering through.

Things you can do right now

These don’t replace medical care, but they can help you feel less miserable while you figure it out:

  • Eat at least one warm, balanced meal a day (protein + carbs + some fat).
  • Drink warm drinks (tea, soup, hot water with lemon) through the day.
  • Wear layers, warm socks, and slippers; keep your head and hands covered.
  • Move your body regularly (even short walks or light exercises at home) to get blood flowing.
  • Avoid sitting still in one position for too long; wiggle fingers and toes, stretch, walk around.

A tiny “story” to frame it

Imagine your body as a small house in winter. If the heater (thyroid) is weak, the insulation (body fat) is thin, the fuel (food and nutrients) is low, or the pipes (circulation) are narrowed, the house never feels quite warm enough, even if everyone else on the street says it’s fine outside.

What to do next

  • If you can, book a primary‑care visit and tell them: “I feel cold all the time,” plus any other symptoms (tired, dizzy, weight changes, mood changes, etc.). They may test blood (thyroid, iron, B12, etc.).
  • If you feel really unwell (chest pain, trouble breathing, almost fainting), seek urgent/emergency care.

If you describe a bit more (how long this has been happening, other symptoms, your general health), I can help you think through what to bring up with a doctor and how to track it.
