Body shivers or a frequent feeling of cold can be caused by various factors. In many cases, it may simply occur when a person is cold or during common viral infections such as the flu, coronavirus, or seasonal illnesses like ARVI. These situations are often temporary and go away as the body recovers.
However, if the sensation of cold becomes persistent or occurs in normal temperature conditions, it may be worth paying attention to possible underlying reasons. Medical professionals note that the body’s temperature regulation depends on several organs and systems, and disruptions in their function may contribute to increased sensitivity to cold.
Possible Contributing Factors
According to medical sources, the following may play a role:
Thyroid function irregularities – The thyroid gland participates in regulating metabolism and temperature. When its function is disrupted, temperature sensitivity may change.
Adrenal gland issues – The adrenal glands work with the hypothalamus, a part of the brain involved in temperature perception. Imbalances may affect how the body responds to heat or cold.
Iron deficiency and low B9/B12 levels – These nutrients support blood health and energy production. Their low levels may lead to fatigue and sensitivity to cold.
Insulin resistance and diabetes – Changes in glucose metabolism may influence circulation and temperature sensations.
Neuropathy and peripheral vascular conditions – These may impact how signals travel through nerves and blood vessels, contributing to discomfort or shivering sensations in normal conditions.
These factors do not necessarily mean a person has a disorder. They are simply examples of medical conditions that have been associated with cold sensitivity in clinical practice.
Why the Brain Is Involved
The hypothalamus, a region of the brain, plays a key role in interpreting temperature. It works together with organs such as the thyroid and adrenal glands. When communication between these systems changes, the brain may respond with stronger or more frequent shivering signals.
This may explain why someone feels cold even when people around them do not.
When to Seek Medical Advice
A healthcare professional should be consulted if:
The shivering becomes persistent
It interferes with daily life
It appears suddenly with no clear cause
There are additional symptoms such as weight change, fatigue, numbness, or dizziness
Only a licensed specialist can provide testing, diagnosis, or treatment recommendations.
Summary
Shivering is often harmless and may occur during common illnesses or in cold environments.
In some cases, thyroid, adrenal, nerve, or blood-related factors may contribute to temperature sensitivity, but only a medical evaluation can determine the cause.
