Why do you keep shiver when not cold?

There are several possible reasons why a person might shiver when they are not cold. Here are a few common causes:

1. Anxiety or stress: Shivering can be a physical reaction to anxiety or stress. When a person is feeling anxious or stressed, their body may release hormones such as adrenaline, which can cause the muscles to contract and relax rapidly, leading to shivering.

2. Fever: Shivering is a common symptom of a fever. When the body's temperature rises, shivering helps to generate heat and raise the body's core temperature to fight off infection.

3. Medications: Certain medications, such as antidepressants and stimulants, can cause shivering as a side effect.

4. Hyperthyroidism: Shivering can be a symptom of hyperthyroidism, a condition in which the thyroid gland produces too much thyroid hormone. This can lead to increased metabolism and body temperature, which can cause shivering.

5. Neurological disorders: Some neurological disorders, such as Parkinson's disease and multiple sclerosis, can cause shivering or tremors as a symptom.

6. Hypoglycemia: Shivering can occur when blood sugar levels drop too low (hypoglycemia). This is because the body needs glucose for energy, and when glucose levels are low, the body may shiver in an attempt to generate heat and raise blood sugar levels.

If you are experiencing shivering and you are not cold, it's important to pay attention to any other symptoms you may be having and consider talking to a doctor to determine the cause and receive appropriate treatment.
