Chills are unusual feelings of coldness. A person who has chills will possibly shiver to a great extent. This can be an uncomfortable feeling which could persist for hours. The incidence of shivering may not stop even if a person is already wearing warm clothes or sleeping under a blanket. Chills accompanied with fever can result to teeth chattering and are frequently due to viral or bacterial infections which trigger an increase in body temperature or fever a lot of times.
Chills without fever causes
Being exposed to Cold Climatic Conditions – Chills occur as the natural response of the body to cold weather. When the body shivers in a cold environment, this would indicate that the body can no longer tolerate the low temperature of the surrounding area. The big difference between the body’s temperature and its surroundings is produced in the form of chills with no fever. It is not surprising that those who are staying in places such as Alaska and Canada are already seasoned to chills and shivers.
Food Poisoning – Sudden uncontrollable shivering without fever can also indicate food poisoning. It is a medical condition which occurs after the consumption of food which contains harmful pathogens. Unhygienic food or food items which are not stored properly can harbor pathogens. Hence, their consumption can possibly result to food poisoning. Even if this food borne illness is usually marked with chills and fever, numerous reports reveal that those who have contracted this illness did not experience increase in body temperature.
Prescription Drugs – Side effects of prescription drugs are common particularly when the dosage of the medication is incorrect. The person who is prescribed with medications for the treatment of a certain disease can experience bouts of persistent chills. Yet, surprisingly, the temperature remains to be normal.
Acute Bronchitis – This is a bacterial or viral infection of the bronchi and tubular passages which carry inhaled air into the lungs. This infection will go away within several weeks and usually result to swelling of the bronchi followed by frequent attacks of breathing problems, cough and chest pain. A common symptom linked to acute bronchitis is chills or fever. Although, chills and fever can be present in acute bronchitis, in majority of cases, either of them can have an effect.
Thyroid Problems – The thyroid gland located in the neck has an extremely important role in the production of hormones which ensure normal metabolic rate for general well-being. Problems of the thyroid could affect the normal production of hormones. If the thyroid hormone is not produced in adequate amounts or if there is hypothyroidism, those who are affected will experience symptoms of chills without an increase in the body temperature as well as extreme tiredness.
