This is normal and is known as a “physiologic tremor.” Certain factors can make the tremor more noticeable, including stress or anxiety, caffeine consumption, and lack of sleep. In some cases, severe or persistent tremors may indicate an underlying medical condition or a side effect of a particular medication.
Feeling shaky is a common symptom of anxiety, and one that most people have experienced at some point in their life. It's sometimes possible for shaking to be the only symptom or one of the first symptoms people notice when they're feeling nervous.
In one 2018 study of over 3,000 adults, those who drank more water had a lower risk of anxiety and depression than those who drank less water. Though the connection between dehydration and depression was stronger, researchers found that anxiety was higher in those who didn't drink enough water.
These symptoms and signs may reflect dehydration from an infectious cause or adrenal insufficiency. The symptoms and signs could be the result of any infection or malignancy that causes high or prolonged fevers or decreased drinking and eating.
Also, jittery applies to people who feel nervous or tense. If you're worried about a test, you'll feel jittery. During the last minute of a basketball game, some players get jittery. Synonyms for this nervous kind of jittery are edgy, high-strung, jumpy, nervy, and uptight.
Feeling nervous, restless or tense. Having a sense of impending danger, panic or doom. Having an increased heart rate. Breathing rapidly (hyperventilation)
The jitteriness syndrome (jitteriness, shakiness, increased anxiety, and insomnia) can develop with low doses of tricyclic antidepressants in patients who are sensitive to these drugs. The authors review the antidepressant treatment of 180 patients.
Your stomach can feel like it's rumbling and you may even feel nauseated. Feeling sick may be a sign that you've fallen ill, but it can also be a sign of anxiety. While feeling sick may be the only physical symptom of anxiety, there are often others including breathlessness, dizziness and fatigue.
Anxiety can be caused by a variety of things: stress, genetics, brain chemistry, traumatic events, or environmental factors. Symptoms can be reduced with anti-anxiety medication. But even with medication, people may still experience some anxiety or even panic attacks.
It's okay to feel anxious, but not all of the time. If you feel that you are experiencing one or more of these symptoms in your daily life or to an intense degree, you may have an anxiety disorder. It's important to reach out to a mental health care provider to help confirm a diagnosis.
Possible medical reasons for anxiety
H (hormones): Thyroid problems are among the most common medical causes of anxiety, either because the gland is overactive (hyperthyroidism) or underactive (hypothyroidism). Parathyroid and adrenal gland conditions can trigger anxiety, too.
The most common physical symptoms of anxiety include fatigue, increased heart rate, heart palpitations, shortness of breath, dizziness, muscle aches, muscle weakness, headaches, digestion, discomfort and tingling sensations.
Deep breathing – Slow, deep breaths can help to bring a sense of calm and reduce hyperventilation. Exercising – Exercise releases pent-up energy and reduces muscle tension to ease physical stress, and distracts your brain from anxious feelings.
Most often this shaking is directly associated with your anxious moment, and while temporary, it usually lasts just as long as the threat is present. Do not be alarmed, if the tremor extends despite resolution of other anxiety symptoms.
Dehydration can sometimes cause feelings of anxiety, depression, and fatigue. To avoid dehydration, be sure to drink plenty of water and other fluids throughout the day. If you're feeling anxious and think you might be dehydrated, try drinking some water.
Summary: Researchers have found that a lack of sleep, which is common in anxiety disorders, may play a key role in ramping up the brain regions that contribute to excessive worrying.
