Cold Hands and Feet Even Under a Blanket? Know When to See a Doctor
If your hands and feet stay cold for long periods—even after sitting under a warm blanket—it may be more than just winter discomfort. Sometimes, the body gives signals about deeper health issues. Here’s what you need to understand.
Why Hands and Feet Stay Cold
Cold extremities commonly happen due to reduced blood flow. But when it becomes persistent, these conditions may be involved:
1. Poor Blood Circulation
When blood vessels narrow, warm blood doesn’t reach the hands and feet properly.
Signs: numbness, tingling, pale or bluish skin.
2. Low Blood Pressure
If BP is very low, the body sends most blood to vital organs, leaving hands and feet cold.
3. Thyroid Problems (Hypothyroidism)
An underactive thyroid slows metabolism and reduces body heat.
Signs: weight gain, fatigue, dry skin, hair fall.
4. Anemia (Low Hemoglobin)
Low iron reduces oxygen supply to tissues, making extremities cold.
Signs: tiredness, dizziness, weakness.
5. Diabetes or Nerve Issues
Damaged nerves and poor circulation can cause constant coldness.
6. Raynaud’s Phenomenon
Blood vessels spasm in cold or stress, causing hands and feet to turn white or blue.
