Shivering (also called shuddering) is a bodily function in response to cold and extreme fear in warm-blooded animals. When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy.
Dec 1, 2017 · A shiver is caused by your muscles tightening and relaxing in rapid succession. This involuntary muscle movement is your body’s natural response to getting colder and trying to warm up....

- Fever. Share on Pinterest. A fever may cause shivering. Other than being cold, the most common cause of shivering is fever, which doctors define as a body temperature higher than 100°F.
- Psychogenic movement disorders. For some people, stress or mental health factors can cause shivering and other involuntary movements. This usually occurs due to a psychogenic movement disorder, which can affect any part of the body.
- Postanesthetic shivering. Share on Pinterest. A person may shiver when recovering from an anesthetic. Shivering can occur when a person regains consciousness after a general anesthetic.
- Fear, excitement, or stress. Strong emotions can cause a person to shake or shiver. This is often due to a surge of adrenaline in the body. Adrenaline is a hormone that triggers the body’s fight-or-flight response.
Mar 10, 2018 · Postoperative shivering (PS) is an involuntary, oscillatory muscular activity during early recovery after anaesthesia. Shivering is defined as the fasciculation of the face, jaw, or head or muscle hyperactivity lasting longer than 15 seconds . This phenomenon is a common occurrence observed in the postanaesthesia care unit.

Dec 22, 2017 · Targeted temperature management is associated with shivering. Treatment methods of shivering include both nonpharmacologic and pharmacologic agents. Best practices include initiating treatment prophylactically at the initiation of TTM. Shivering interventions should be assessed with the help of a shivering scale.

Feb 20, 2024 · Shivering usually starts 1 to 30 minutes after giving birth and lasts for 2 to 60 minutes. The cause is unknown; it may be a response to a fall in body temperature following labor, fetal-maternal bleeding, micro-amniotic emboli, placental separation, anesthesia, bacteremia, or administration of certain drugs (eg, misoprostol).
Description and treatment. Postanesthetic shivering is one of the leading causes of discomfort in patients recovering from general anesthesia. It usually results due to the anesthetic inhibiting the body's thermoregulatory capability, although cutaneous vasodilation (triggered by post-operative pain) may also be a causative factor.
