Some people experience frequent chills or goosebumps even in hot weather—a condition that can feel puzzling and uncomfortable. But what causes this sensation, and could it be a sign of something serious?

According to experts, this abnormal temperature regulation often stems from underlying medical conditions. The most common causes include:
1. Iron Deficiency
This is the most widespread cause of feeling cold. Low iron levels reduce hemoglobin in the blood, limiting its ability to carry oxygen to vital organs and tissues. As a result, the body tries to compensate by dilating blood vessels to increase circulation, leading to a persistent feeling of coldness or chills.
This also explains why many women feel colder during their menstrual period, when iron levels can drop.
2. Low Thyroid Hormones (Hypothyroidism)
An underactive thyroid gland leads to decreased production of hormones that regulate metabolism. A slow metabolism lowers the body’s core temperature, making the person feel cold, even in warm conditions.
If persistent chills are accompanied by symptoms like fatigue, weight gain, or dry skin, it's wise to get thyroid function tested.
3. High Blood Sugar (Diabetes)
Diabetes may impair the body’s ability to nourish cells and tissues, resulting in low energy availability. When this happens, the body begins to conserve energy, including the energy used to maintain body temperature, which can lead to chills.
Another factor is diabetic neuropathy, a type of nerve damage caused by high blood sugar. This can affect the body’s ability to regulate temperature and blood flow properly.
If chills are accompanied by constant thirst, frequent urination, or cravings for sugar and carbs, checking blood glucose levels is recommended.
When to See a Doctor?
If you experience frequent chills along with other symptoms (fatigue, weight changes, or metabolic irregularities), it’s important to consult a healthcare provider for blood tests and hormonal evaluations.
