Microphobia (Fear of Small Things)


What is microphobia?

Microphobia is an extreme fear of small things. It’s a specific phobia, meaning that it causes fear of a particular situation. The fear is typically much greater than the actual risk of danger. People can have more than one specific phobia. In addition to microphobia, they might have:

  • Entomophobia: Fear of insects.
  • Iatrophobia: Fear of doctors.
  • Mysophobia: Fear of germs.
  • Nosocomephobia: Fear of hospitals.
  • Nosophobia: Fear of disease.
  • Thanatophobia: Fear of death.

What is a phobia?

It’s natural to fear things that make you feel uncomfortable or unsafe. Blood, heights and airplanes give many people anxiety. But their anxiety isn’t usually so intense that it disrupts their daily lives. Phobias are intense feelings of fear. When you have a phobia, you may go out of your way to avoid situations that trigger it. These efforts can overtake rational thinking, leading to abnormal thoughts and behaviors.

Do I have microphobia?

Little things are a part of everyday life. Most of them cause no harm. But in some people, they cause a level of fear that’s out of proportion to the actual threat. If you have microphobia, the thought of little things can bring on severe anxiety. It can sometimes cause panic attacks. If you have signs of microphobia, discuss your concerns with your healthcare provider. There’s no reason to feel self-conscious about having a phobia. Treatments can help you feel better. And your healthcare provider can help you receive the therapies that are best for your needs.

Genetics and environmental factors can increase the risk of specific phobias like microphobia:

Diagnosis and Tests

How is microphobia diagnosed?

Healthcare providers diagnose microphobia by asking about your symptoms and behaviors.

They may ask:

  • How exposure to small objects makes you feel.
  • Which little things you find bothersome.
  • Whether the fear of small things is causing you to make changes in your daily routine.
  • If there’s a personal or family history of anxiety disorders or phobias.
  • How often you think about little things.
  • The type and severity of symptoms you experience related to small objects.
  • If you’re avoiding activities or places you used to enjoy because of this phobia.

Management and Treatment

What is microphobia treatment like?

A common treatment for microphobia is exposure therapy. Your therapist exposes you to situations that trigger your fear of little things. Exposure therapy for microphobia may start with pictures of germs or other small objects.

Over time, you may progress to touching small objects or going somewhere you’ve been too anxious to go. With successful treatment, seeing or being around little things in your life becomes less bothersome.

Can other treatments help me cope with microphobia?

Additional treatments may include:

  • Cognitive behavioral therapy (CBT): Using CBT, your therapist helps you explore why small objects make you feel anxious. They also teach you healthier alternatives to negative thoughts or behaviors.
  • Medications: Medications don’t cure microphobia. But antidepressants can help with mood disorders, and anti-anxiety medications can help you through a challenging time. If you’re anxious about going back out in public again, where you might encounter little things, medications may help ease the transition.
  • Stress reduction: These techniques help quiet your mind and relax your body. Yoga and meditation can help you become more in touch with your thoughts and feelings. This can reduce the likelihood of panic when you encounter little things.
