Why Do I Shake When I Wake Up In The Morning?

Many people experience shaking or tremors when they wake up in the morning, which can be unsettling and concerning. There are various reasons why this might occur, and in this article, we will explore some of the most common causes.

Muscle Fatigue

One of the most common reasons for shaking in the morning is muscle fatigue. Our muscles can become tired and stiff after sleeping in the same position for an extended period. When we wake up and start moving around, our muscles need time to warm up and regain their strength. This can cause shaking or trembling in the muscles, particularly in the arms and legs.

Low Blood Sugar

Low blood sugar, also known as hypoglycemia, can also cause shaking in the morning. When we sleep, our bodies continue to burn energy, and our blood sugar levels can drop. This can cause us to wake up feeling shaky, weak, and disoriented. Eating a balanced breakfast or snack in the morning can help raise blood sugar levels and alleviate shaking.

Parkinson’s Disease

Parkinson’s disease is a progressive neurological disorder that can cause tremors, stiffness, and difficulty with movement. While shaking in the morning is not necessarily a definitive sign of Parkinson’s disease, it can be an early symptom. If shaking is accompanied by other symptoms such as stiffness, slowness of movement, or difficulty with balance, it is essential to speak with a doctor.

Essential Tremor

Essential tremor is a neurological disorder characterized by involuntary shaking or trembling, most commonly in the hands, arms, and head. While the cause of essential tremor is not entirely understood, it is thought to be related to abnormal brain activity. Essential tremor can occur at any time of the day, but many people experience it in the morning when they are fatigued or dehydrated.

Anxiety and Stress

Anxiety and stress can cause a range of physical symptoms, including shaking or trembling. When we are anxious or stressed, our bodies release adrenaline, which can cause our muscles to contract and shake. Many people experience anxiety or stress first thing in the morning, which can contribute to shaking.


Shaking in the morning can be caused by a range of factors, including muscle fatigue, low blood sugar, neurological disorders, anxiety, and stress. While occasional shaking is typically not a cause for concern, if it is persistent or accompanied by other symptoms, it is essential to speak with a doctor. Maintaining a healthy diet, staying hydrated, and getting enough rest can help alleviate shaking and improve overall health and well-being.
