Why do I feel cold all over despite hot weather?

Feeling cold all over despite hot weather may be caused by physiological reasons or pathological conditions such as colds or depression. It is important to seek medical attention promptly and follow the doctor's instructions for treatment. Details are as follows:

I. Physiological Causes

Excessive sweating can cause the body to lose large amounts of water and heat, leading to an imbalance in temperature regulation, a drop in skin temperature, and a sensation of feeling cold even when the weather is hot. This is a normal physiological phenomenon and generally does not require treatment.

II. Pathological Causes

1. Cold

When a viral infection causes a cold, the virus can stimulate the immune system and affect the body's temperature regulation center, resulting in dysregulation of body temperature. This may lead to a sensation of feeling cold all over even in hot weather. It is recommended to take medications such as acetaminophen capsules, ibuprofen sustained-release capsules, or compound pseudoephedrine hydrochloride sustained-release capsules under medical guidance.

2. Depression

Individuals with depression may experience increased emotional distress and anxiety, leading to autonomic nervous system dysfunction and loss of control over body temperature regulation, which can result in feeling cold all over despite hot weather. Antidepressant treatment using medications such as amitriptyline hydrochloride tablets, sertraline hydrochloride tablets, or paroxetine hydrochloride tablets may be conducted as directed by a physician.

In addition, some patients may experience chills despite high ambient temperatures due to certain medications. In such cases, timely medical evaluation is necessary to determine the underlying cause.
