Insomnia and overthinking often go hand-in-hand. So people with insomnia will commonly try to shut out thoughts that are stopping them from sleeping. This might sound sensible at first, but it can cause more problems than it solves.
Stress and anxiety can cause racing thoughts at night that prevent you from getting the sleep you need. By identifying your stress, scheduling time to attend to your worries, and establishing a healthy bedtime routine, you may be able to avoid racing thoughts and sleep more soundly.
“The scientific term for racing thoughts is rumination, which is likely caused in part by over-activation of the brain's frontal cortex,” says sleep specialist Michael Breus, PhD, author of "The Power of When." “Ruminative thinking is almost always due to anxiety, and it's considered a symptom of insomnia.”
Racing Mind and Anxiety
Rapid thoughts are often a symptom associated with anxiety. They can make people feel out of control or as if they are going crazy. When it comes to sleep, this effect of anxiety is a cyclical problem. Because your brain struggles to focus when it is tired, it often leads to racing thoughts.
Depression, anxiety, and other mental health issues can also cause sleep problems. Whether chronic or acute, these conditions are stressful which means they trigger that same elevated cortisol release that keeps you awake at night. In addition, sleep disturbances are often a symptom of a mood or anxiety disorder.
Taking a warm bath before bedtime may also help reduce paranoia. If your fears are related to the dark, it can be okay to turn on a lamp or nightlight if it isn't too bright that it keeps you awake. Creating white noise with a fan or an app with different sound options can also help you relax.
Medication for intrusive thoughts
Some recommended medications for OCD include: Clomipramine (Anafranil) Fluoxetine (Prozac) Fluvoxamine (Luvox)
Antipsychotics are commonly prescribed to help with symptoms such as hallucinations, delusions, or racing thoughts, but can also be prescribed for individuals without those symptoms. Some antipsychotics are considered mood stabilizers because they, too, even out the highs and lows.
They're usually harmless. But if you obsess about them so much that it interrupts your day-to-day life, this can be a sign of an underlying mental health problem. Intrusive thoughts can be a symptom of anxiety, depression, or obsessive-compulsive disorder (OCD).
Intrusive thoughts are often triggered by stress or anxiety. They may also be a short-term problem brought on by biological factors, such as hormone shifts. For example, a woman might experience an uptick in intrusive thoughts after the birth of a child.
The results of the study showed that OCD may be associated with vitamin D deficiency and there is a moderately negative correlation between serum vitamin D levels and OCD symptom severity.
Overthinking is commonly associated with generalized anxiety disorder (GAD), says Duke. GAD is characterized by the tendency to worry excessively about several things. “Someone can develop GAD due to their genes. Or it could be personality factors like the inability to tolerate uncertainty in life.
People who overthink things regularly, psychologists believe, are often those who may have larger self-esteem or acceptance issues, Dr. Winsberg explains. If you're constantly overthinking (more on that later), however, it may be a symptom of clinical anxiety and depression or even obsessive-compulsive disorder.
Life stressors—such as job stress, familial stress, financial stress, or experiencing a major life transition—is the most frequent cause of racing thoughts at night. This is likely the cause if the experience of racing thoughts at night is new to you, and can be traced to a new stressor or stressful event.
At night, our mind is a big open space. And when we're tired and our minds are left wide open, we're a lot more vulnerable to intrusive, anxious thoughts. If your nighttime anxiety is impacting your ability to function every day, consider seeking the help of a mental health professional.
Antidepressants: Certain antidepressants can be effective in treating anxiety and racing thoughts. Selective serotonin reuptake inhibitors (SSRIs) are commonly used. Antihistamines: Some over-the-counter antihistamines, such as diphenhydramine (Benadryl®), can have a sedating effect and may be used to help with sleep.
Magnesium Improves Brain Chemicals that Help Anxiety, OCD, Depression, and ADHD. Magnesium plays an essential role in neurologic function, including involvement in neurotransmitter synthesis, nerve transmission and neuromuscular conduction.
Some research studies have found evidence to suggest that oxytocin is associated with OCD. We review the growing evidence that suggests oxytocin and gonadal steroids might play a role in the pathogenesis of some forms of OCD.
What drives this is underlying anxiety. Common forms include worrying, perfectionism, struggle with making decisions, and excessive control over yourself and others. Keys to coping include getting your rational brain online, using your gut reactions as important information, and taking acceptable risks.
