Are you experiencing morning shakiness? Why Do I Wake Up Shaking? At WHY.EDU.VN, we provide answers to your health concerns, offering insights into the potential causes of morning tremors and what you can do about it. Let’s explore the reasons behind waking up with the shakes and find solutions to improve your mornings, including panic disorder and mental health.
1. Low Blood Sugar: A Common Cause of Morning Shakes
Low blood sugar, clinically known as hypoglycemia, can frequently trigger tremors upon waking. According to the Mayo Clinic, hypoglycemia occurs when glucose levels dip below the normal range. Besides shaking, other indicators of hypoglycemia include:
- Irregular or rapid heartbeat
- Intense hunger
- Irritability
- Numbness or tingling around the mouth
- Anxiety
- Fatigue
How to Fix It: Consume 15 to 20 grams of fast-acting carbohydrates, such as fruit juice or glucose tablets, to quickly raise blood sugar levels. Soft drinks or candy can also work if you don’t have immediate access to those options.

Tip: Consult your physician about adjusting the timing of your meals and medications if you are diabetic to stabilize your blood sugar.
2. Panic Attacks: Nighttime Episodes of Intense Fear
Panic attacks, though not as common, can occur during sleep and cause you to wake up shaking. Nighttime panic attacks often lack an obvious trigger, according to the Mayo Clinic. Symptoms are similar to daytime panic attacks and may include:
- Sweating
- Trembling
- Rapid heart rate
- Shortness of breath
- Flushing or chills
- Sense of impending doom
Warning: These symptoms can mimic those of a heart attack, particularly in women. Seek immediate medical attention if you suspect a heart attack by calling 911.
How to Fix It: Cognitive behavioral therapy and medication can effectively treat panic attacks. Addressing the root causes of your anxiety is also beneficial.
Tip: Find a qualified therapist who can help you explore and manage the underlying causes of your panic attacks.
3. Anxiety: A Constant State of Unease
Consistent anxiety can also manifest as morning shakiness. Common anxiety symptoms, as outlined by the Mayo Clinic, include:
- Trembling
- Restlessness or feeling on edge
- Fatigue
- Gastrointestinal issues
- Sleep disturbances
- Difficulty concentrating
- Excessive sweating
How to Fix It: There are numerous ways to alleviate anxiety. Therapy, breathing exercises, and grounding techniques can make a significant difference.
4. Medication Side Effects: The Unintended Consequences
Certain medications may cause you to feel shaky upon waking. Albuterol, commonly prescribed for asthma, can lead to side effects such as:
- Headache
- Throat or nasal irritation
- Muscle aches
- Nervousness or shakiness
Other medications that might induce shakiness include corticosteroids, antidepressants, nicotine, alcohol, Ritalin, Sudafed, and cyclosporine, according to the Cleveland Clinic.
How to Fix It: Consult your doctor about potential alternatives, dosage adjustments, or different administration methods if you suspect your medication is the culprit.
5. Excessive Caffeine Intake: The Jittery Effect
Overconsumption of caffeine, found in coffee, soda, energy drinks, and snack bars, can lead to jitteriness and shaking. UW Medicine suggests that more than 400 milligrams of caffeine daily is excessive for adults. Other symptoms of too much caffeine include:
- Sweating and restlessness
- Anxiety
- Nausea and diarrhea
How to Fix It: Cut back on caffeine, stay hydrated, replenish electrolytes if experiencing nausea or diarrhea, and practice deep breathing exercises to mitigate the effects.
6. Alcohol Withdrawal: The Morning After
Alcohol withdrawal can trigger tremors, particularly in individuals who regularly consume alcohol. Symptoms of alcohol withdrawal, according to the National Institute on Alcohol Abuse and Alcoholism (NIAAA), include:
- Shakiness or tremors
- Anxiety
- Nausea
- Sweating
- Headache
- Seizures
How to Fix It: Medical detoxification is often necessary for managing alcohol withdrawal. Consult a healthcare professional for safe and effective treatment.
7. Sleep Disorders: Disrupting Restful Nights
Certain sleep disorders, such as restless legs syndrome (RLS) or sleep apnea, can disrupt sleep and cause morning shakiness. RLS can cause an irresistible urge to move the legs, while sleep apnea leads to pauses in breathing during sleep, according to the National Sleep Foundation.
How to Fix It: Diagnosis and treatment of underlying sleep disorders can improve sleep quality and reduce morning shakiness. Consult a sleep specialist for evaluation and management.
8. Thyroid Issues: Hormonal Imbalances
An overactive thyroid, or hyperthyroidism, can cause tremors and shakiness. Symptoms of hyperthyroidism, as reported by the American Thyroid Association, include:
- Tremors
- Rapid heartbeat
- Weight loss
- Anxiety
- Sweating
How to Fix It: Treatment for hyperthyroidism includes medication, radioactive iodine therapy, or surgery. Consult an endocrinologist for proper diagnosis and management.
9. Neurological Conditions: Underlying Issues
In some cases, morning shakiness may indicate an underlying neurological condition such as Parkinson’s disease or essential tremor. These conditions affect the nervous system and can cause tremors, stiffness, and difficulty with movement, according to the National Institute of Neurological Disorders and Stroke (NINDS).
How to Fix It: A neurologist can diagnose and manage neurological conditions through medication, therapy, and lifestyle modifications.
10. Dehydration: The Lack of Fluids
Dehydration can lead to electrolyte imbalances and cause muscle cramps and shakiness. Not drinking enough water, especially before bed, can contribute to morning tremors.
How to Fix It: Increase your fluid intake throughout the day, particularly before bed. Electrolyte-rich drinks can also help restore balance.
When Should You See a Doctor?
Consult your doctor if you frequently wake up shaking or trembling. Dr. Savoy suggests considering the following questions to help your doctor determine the cause:
- How often and how intense is the shakiness?
- Does it occur at other times of the day?
- Are you experiencing other symptoms like headaches, blurry vision, or muscle weakness?
- Did you eat and hydrate sufficiently the previous day?
- Have you started any new medications, vitamins, or supplements?
Your answers will assist your doctor in identifying and treating the cause of your shakiness.
