Why Am I Shaking When I Wake Up?


Shaking when waking up is a common experience that many people have reported. It can occur for a variety of reasons, including medical conditions, stress, and low blood sugar. In this article, we will explore some of the common causes of shaking when waking up.


One of the most common causes of shaking when waking up is hypoglycemia, which is a low level of sugar (glucose) in the blood. When blood sugar levels drop, the body responds by releasing hormones that cause shaking and other symptoms. Hypoglycemia is often seen in people with diabetes who take insulin or other medications that lower blood sugar levels. However, it can also occur in people who do not have diabetes, especially if they have not eaten for a long period of time.

Anxiety and Stress

Anxiety and stress can also cause shaking when waking up. When the body experiences stress or anxiety, it releases adrenaline, a hormone that prepares the body for a “fight or flight” response. This can cause shaking, sweating, and other symptoms. Anxiety and stress can also disrupt sleep patterns, making it more likely that someone will wake up feeling shaky.

Parkinson’s Disease

Parkinson’s disease is a degenerative disorder of the nervous system that can cause tremors and shaking. These symptoms are often most noticeable when the person is resting or waking up from sleep. Other symptoms of Parkinson’s disease include rigidity of the muscles, slowness of movement, and difficulty with balance and coordination.

Essential Tremor

Essential tremor is a neurological disorder that causes involuntary shaking or trembling, especially in the hands. The tremors can also occur in the head, voice, and other parts of the body. Essential tremor is more common in older adults and can be worsened by stress, fatigue, or caffeine.

Other Medical Conditions

Shaking when waking up can also be caused by other medical conditions, such as hyperthyroidism, multiple sclerosis, or alcohol withdrawal. In some cases, medications or drug use can also cause shaking.


Shaking when waking up can be a concerning symptom, but it is often caused by benign factors such as hypoglycemia or stress. However, it is important to speak with a healthcare provider if shaking is accompanied by other symptoms or if it is interfering with daily life. A healthcare provider can help determine the underlying cause of shaking and recommend appropriate treatment options.
