For most people, a boost of energy is a positive experience, often tied to excitement or productivity. However, when this energy becomes abnormally intense, prolonged, or disruptive to daily functioning, it may point toward an underlying health condition. Understanding the differences between these various high-energy states is the first step toward finding a solution.
Mental Health Conditions Causing High Energy
Several psychiatric disorders can manifest with periods of significantly increased energy. These are often accompanied by other changes in mood, thought patterns, and behavior that distinguish them from a typical boost of motivation.
Bipolar Disorder: Mania and Hypomania
Bipolar disorder is a mental health condition defined by extreme mood swings that include emotional highs (mania or hypomania) and lows (depression).
Mania: A true manic episode is an abnormally elevated or irritable mood lasting for at least one week and is accompanied by several other symptoms. It is a hallmark of Bipolar I disorder and often causes severe disruptions to a person's life, sometimes requiring hospitalization. Symptoms include:
- An intense, euphoric, or irritable mood.
- Inflated self-esteem or grandiosity.
- Decreased need for sleep (feeling rested after only a few hours).
- Increased or rapid speech.
- Racing thoughts.
- Distractibility.
- Impulsive and risky behavior (e.g., reckless spending, foolish investments).
Hypomania: This is a less severe form of mania and is a feature of Bipolar II disorder. Hypomanic episodes typically last at least four days and involve an elevated mood and increased energy, but they do not cause the same level of functional impairment or involve psychosis as manic episodes. While it may initially feel productive or euphoric, it can still lead to poor judgment and is often followed by a depressive episode.
Attention-Deficit/Hyperactivity Disorder (ADHD)
ADHD is a neurodevelopmental disorder that involves ongoing patterns of inattention and/or hyperactivity-impulsivity. Unlike the episodic nature of bipolar disorder, hyperactivity in ADHD is a more consistent trait, present in multiple settings from a young age.
Symptoms of hyperactivity include:
- Fidgeting and squirming while seated.
- Feeling restless, as if driven by an internal motor.
- Talking excessively.
- Difficulty engaging in quiet activities.
- Running or climbing excessively (in children).
Anxiety Disorders
While not typically associated with euphoria, chronic or severe anxiety can create a sense of nervous energy and restlessness. This agitated energy is often driven by worry and tension rather than a feeling of being 'on top of the world' like in mania. Symptoms can include:
- Restlessness or feeling on edge.
- Agitation or irritability.
- Difficulty sleeping due to racing, worried thoughts.
- A need to constantly be moving or doing something to relieve tension.
Physical Health Conditions Linked to Increased Energy
Sometimes, heightened energy is a symptom of a physiological issue rather than a mental health disorder. It is important to rule out these physical causes through medical examination.
Hyperthyroidism (Overactive Thyroid)
Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone, which controls the body's metabolism. An overactive metabolism can initially cause a surge in energy, leading to restlessness and a sense of being 'amped up'. However, this overstimulation eventually exhausts the body, often leading to fatigue. Other symptoms include:
- Increased heart rate.
- Weight loss despite a good appetite.
- Nervousness and irritability.
- Trouble sleeping.
- Heat intolerance.
- Hand tremors.
Graves' disease is an autoimmune condition and the most common cause of hyperthyroidism.
Substance Use and Medication Side Effects
Some substances can directly affect the central nervous system and mimic manic or hypomanic symptoms. These include:
- Stimulants: Cocaine, amphetamines, and even excessive caffeine can cause increased energy, restlessness, and insomnia.
- Medications: Certain prescription drugs, such as some antidepressants or steroids, can trigger manic or hypomanic episodes in vulnerable individuals.
- Alcohol Withdrawal: For people with alcohol dependence, withdrawal can induce agitation and high energy.
How to Distinguish Between High-Energy States
Given the overlap in some symptoms, telling the difference between a high-energy mental or physical condition can be complex. A doctor will typically consider the intensity, duration, and other accompanying symptoms to make an accurate diagnosis. The table below helps differentiate key conditions:
| Feature | Mania | Hypomania | ADHD (Hyperactivity) |
|---|---|---|---|
| Duration | At least one week | At least four consecutive days | Ongoing for at least 6 months |
| Severity | Severe; often significantly impairs social or occupational functioning | Milder; may not significantly impair functioning but is noticeable to others | Persistent and disruptive to daily functioning |
| Psychosis | Can be present (e.g., hallucinations, delusions) | Not present | Not present |
| Key Energy Symptom | Elevated mood, racing thoughts, decreased need for sleep | Elevated mood, increased activity, heightened creativity | Fidgeting, restlessness, feeling driven by a motor |
| Associated State | Often followed or preceded by depressive episodes | Occurs with depressive episodes in Bipolar II | May co-occur with other disorders like anxiety or depression |
When to Seek Professional Help
It is essential to consult a healthcare professional if you or a loved one experience persistent or concerning changes in energy levels, mood, and behavior. A proper diagnosis from a qualified medical or mental health professional is the only way to determine the cause and develop an effective treatment plan.
Consider seeking an evaluation if you observe:
- Persistent elevated energy accompanied by poor judgment or risky behavior.
- Significant changes in sleep patterns without feeling tired.
- Abrupt or extreme mood swings, from high energy to depression.
- An inability to function at work, school, or in social settings.
Conclusion
While a boost of energy can be a sign of wellness, it can also be a red flag for a more serious underlying condition. Bipolar disorder, with its manic and hypomanic phases, is a primary cause, but conditions like hyperthyroidism and ADHD also involve abnormal energy levels. Since each condition requires a different approach to management, an accurate diagnosis is crucial. By paying close attention to the nature, intensity, and duration of energy shifts, and by consulting with a healthcare provider, individuals can get the right support and regain balance.
