Shivering is an involuntary movement of the body, often caused by exposure to cold. It can also be caused by a fever, low blood sugar, fear, or anxiety. Shivering in your sleep could be caused by a variety of factors, including the temperature of your environment, underlying health conditions, or even anxiety. Sleep myoclonus, a condition characterised by involuntary muscle jerks or spasms during sleep, could also be a reason for shivering in your sleep.

What You'll Learn
A decrease in core body temperature is normal before falling asleep
Shivering is an involuntary movement of the body, which means that it is uncontrolled. It occurs most commonly when a person is cold. When muscles move, they generate heat, so when a person is cold, their muscles begin to tighten and loosen rapidly to produce heat. This is known as shivering. It is usually temporary and should stop once the individual warms up.
Despite this, a cooler temperature could negatively impact your sleep. A study found that participants' sleep was more affected by cool temperatures than warm ones. Ideally, your sleep environment should be slightly cooler, but if you're experiencing chills, it may be too cold. You can take steps to adjust your environment and create a comfortable temperature for sleep. For example, you could use a hot water bottle or extra blankets, or pay attention to the type of bedding and sleepwear you use.
However, shivering can also be a symptom of physical or mental illness. For example, it can be a sign of low blood sugar, or that your body is fighting off a viral or bacterial infection. It can also be caused by anxiety or psychological trauma, such as post-traumatic stress disorder (PTSD). If you feel especially cold and simple measures to warm up, such as putting on a sweater or turning up the temperature, do not help, you should see a doctor.

Shivering is a symptom of low blood sugar
Shivering can be caused by various factors, including exposure to cold, fever, anxiety, and low blood sugar. While it is a natural response to cold temperatures, shivering can also indicate a drop in blood sugar levels, known as hypoglycemia.
Hypoglycemia refers to a condition where the level of sugar (glucose) in the blood drops below the healthy range. This can occur due to various factors, including missing meals, increased physical activity, certain medications, and liver or kidney disorders. People with diabetes are particularly susceptible to hypoglycemia, especially if they take insulin to manage their blood sugar. However, it can also affect those without diabetes in rare cases due to factors such as malnutrition, binge drinking, or certain medical conditions.
The symptoms of hypoglycemia include shakiness, trembling, sweating, hunger, and fatigue. In more severe cases, individuals may experience confusion, difficulty concentrating, heart palpitations, coma, or even death. Therefore, it is crucial to treat hypoglycemia promptly by consuming carbohydrates or glucose to raise blood sugar levels. For those with diabetes, regular monitoring of blood sugar levels and managing insulin intake are essential to prevent hypoglycemia.
Shivering during sleep, or nocturnal hypoglycemia, can be particularly dangerous as it may go unnoticed, leading to severe symptoms. If you experience nocturnal hypoglycemia, it is recommended to regularly check your blood sugar levels before bed and throughout the night. Maintaining proper diabetes management and seeking medical advice are crucial to preventing and managing hypoglycemia effectively.
In summary, shivering can be a symptom of low blood sugar, and it is important to recognize this as part of a broader set of symptoms. Prompt treatment and management of hypoglycemia are essential to prevent severe health complications.

Night sweats and shivering can be symptoms of menopause
Shivering is typically caused by exposure to cold or the onset of a fever. However, it can also be a symptom of underlying physical or mental health conditions. For instance, shivering can be a response to low blood sugar, fear, or anxiety. In some cases, it may be a symptom of more serious conditions such as Parkinson's disease or essential tremor.
The severity of menopause-related symptoms can vary significantly between individuals and even within the same person over time. While night sweats and shivering can be uncomfortable and disruptive, there are treatments available to help alleviate these symptoms. Hormone therapy, such as estrogen or progestin, can be effective in managing menopause-related night sweats and other symptoms like bone loss and vaginal dryness. However, it is important to note that hormone therapies carry certain risks, including blood clots and gallbladder inflammation.
Non-hormonal treatments for night sweats and shivering associated with menopause include lifestyle changes, dietary supplements, and nonhormonal medications. It is recommended to consult a healthcare professional to determine the most suitable treatment option based on individual needs and circumstances. Additionally, addressing the underlying cause, investing in breathable bedding, cooling the bedroom, and relieving stress before bed can help reduce night sweats and improve sleep quality.
While menopause is the most common cause of night sweats, there are other potential causes to consider. Night sweats can also be a side effect of certain medications or underlying health conditions such as infections, diabetes, or cancer. Therefore, it is important to consult a healthcare provider to diagnose and treat any underlying conditions that may be contributing to night sweats and shivering.

Shivering can be a symptom of anxiety
Shivering is an involuntary movement of the body, which means that it is uncontrolled. Shivering occurs most commonly when a person is cold. When we feel cold, our muscles rapidly tighten and loosen, generating heat. However, shivering can also be caused by other factors, such as low blood sugar, fear, or underlying medical conditions.
Shivering can also be a symptom of anxiety. Anxiety shivers are physical symptoms caused by anxiety disorders. They can occur during panic attacks, anxiety attacks, social anxiety, generalized anxiety, or as a symptom of PTSD. These shivers are the result of the body's fight-or-flight response, which is an evolutionary reaction to prepare us for potential dangers. When we experience acute stress, panic, or heightened anxiety, our bodies release hormones such as adrenaline and cortisol, leading to intense physical sensations.
The physical symptoms of anxiety can include a rapid heart rate, nausea, stomachaches, shortness of breath, dilated pupils, muscle aches, and headaches. Shaking from anxiety can be uncomfortable and even frightening, causing further stress. It can interfere with daily life, especially when it occurs suddenly without an apparent trigger.
To manage anxiety shivers, it is crucial to address the underlying anxiety. This can be achieved through various treatments, including therapy, medication, and lifestyle changes. Therapy techniques such as cognitive-behavioral therapy (CBT) and talk therapy can help identify and change negative thought patterns and underlying causes of anxiety. Medications like SSRIs (selective serotonin reuptake inhibitors) and benzodiazepines can also help manage anxiety and its physical symptoms. Additionally, self-help methods such as breathing techniques, yoga, mindfulness, progressive muscle relaxation, and spending time with supportive loved ones can aid in calming the nervous system and reducing anxiety symptoms.
If you experience anxiety shivers, it is important to seek professional help to rule out other potential causes and develop an effective treatment plan.

Shivering can be caused by a cold room
Shivering is an involuntary movement of the body, which means that it is uncontrolled. Shivering occurs most commonly when a person is cold. When muscles move, they generate heat. Therefore, when a person is cold, their muscles begin to tighten and loosen rapidly to produce heat. This is known as shivering. It is usually temporary and should stop once the individual warms up.
The ideal room temperature for sleep is said to be 65 degrees Fahrenheit. However, this is not a universal standard. It's important to process your personal data. Choose your bedding and sleepwear accordingly. The warmest option is not always the best if you want to avoid getting cold. If you get too hot, you'll get soaked in sweat, making you cold later on. Choose a breathable, moisture-wicking material like bamboo, merino wool, cotton, and linen. Use flannel instead of fleece to add warmer layers.
If you are feeling cold, you can keep a hot water bottle under your blankets to keep your bed warm. Keep extra blankets nearby and layer them on top of you if you wake up feeling chilly at night.
