Unlike milder fears, phobias may get in the way of proceeding with your life.

Animal phobias are likely the most common type of phobias, followed by an extreme fear of heights.

An intense fear must persist for at least six months to be diagnosed as a phobia.

Where do phobias come from?

Scientists say phobias are extreme version of a primitive evolutionary mechanism that tells us when danger is near or we are in a dangerous situation. A number of brain regions work in concert to trigger flight or fight responses, and with some...

How the feared self fuels OCD

Obsessive-compulsive disorder is characterized by intrusive thoughts that prompt people to enact compulsions—behaviors intended to relieve the anxiety or stress from the obsession. A significant intrusive thought OCD sufferers endure is the fear they will become a dangerous or immoral person. Therapeutic approaches try to show patients this is just a story that can be set aside.

Fear or disgust related to clusters of holes and cracks, called trypophobia, may stem from evolutionary processes to help us avoid pathogens.

Brain conditions and surgery can cause some individuals to feel no fear

Fear is a survival mechanism that originates in the brain's amygdala, triggering the body's fight-or-flight response. However, in modern society, without the same natural dangers, fear can lead to anxiety and mental health issues when unnecessarily triggered. Understanding individuals without fear may help identify new methods to treat anxiety disorders.

Apeirophobia is the fear of everlasting life and may stem from the human brain's inability to conceptualize the concept of anything happening beyond what it can project out, such as the concept of an infinite life.

Fearology, or the study of fear, explores the difference between stress and fear

Our brains involuntarily respond to our environment and signal alarm when that isn't always needed, triggering responses that include goose bumps. But understanding fear and how to talk our brains into calming down can improve daily life.

Lesser-known phobias include turophobia, or the fear of cheese, and nomophobia, the fear of being without your cell phone.

Horror offers opportunities to safely experiment with fear

Researchers at Denmark's Aarhus University study people attracted to what they call "recreational fear," which includes any media (like a horror movie) or experience (like a haunted house) that's intended to give them a scare. They say these people appreciate playing with fears and anxieties safely.

He tackles how psychedelics work, explains microdosing and psychedelic risks, how the substances could be used to treat addiction, and the history of psychedelic stigma.

Panic attacks are intense fear episodes that often occur without a clear trigger

Unlike typical fear responses to real danger, panic attacks can mimic serious health problems, such as heart attacks. Sweating during a panic attack may seem random, but it's a leftover survival mechanism that made it easier for our ancestors to escape by slipping out of an attacker’s grasp.

Some claim breathwork can improve mental health, help process trauma, and more

Research shows people who practice breathing exercises see a decrease in depression and stress levels, and that such exercises are about as effective at treating PTSD as conventional approaches. Even something as simple as extending exhales can slow one's heart rate and activate the parasympathetic nervous system.

How to build curiosity

Change and uncertainty induce stress, but reframing the unknown into an opportunity for discovery has tangible benefits. Approaching change with curiosity enhances activity in the hippocampus and promotes neuroplasticity, promoting learning and serving as a barrier against anxiety. A neuroscientist explains how embracing the unknown, trying small experiments, and other techniques build curiosity.

CBT helps rewire the brain's false beliefs by challenging negative thoughts

Cognitive behavioral therapy identifies how specific situations can trigger distorted core beliefs—often formed early in life—that negatively shape thoughts and behavior. It frequently uses structured questioning that promotes self-reflection to uncover distorted thinking and guide people toward more balanced perspectives.

Fear (and stress) can be contagious via pheromones secreted by the body

While seeing someone else in a panicked state may induce a stress response, researchers have found stress can be literally contagious—chemicals contained in sweat and other secretions can trigger stress hormone release in others. Theories suggest this feature is an evolutionary adaptation to protect groups from danger.

Does our fear of Alzheimer's create stigma around its treatment?

Surveys suggest our fear of Alzheimer's as a disease outranks that of heart disease and cancer. This piece argues our fear of aging and the slipping away of our mental capacities make it more difficult to treat Alzheimer's compassionately.

Why are humans hooked on horror?

A haunted horror attraction in Denmark is regularly stalked by researchers of the world's only laboratory dedicated to understanding fear's good side. Fear is one of many human emotions that correspond to a physiological response. As fear rises, so do adrenaline, cortisol, and heart and breath rates. As it ebbs, the body is flooded with dopamine, a hormone and neurotransmitter associated with desire, learning, and motivation.

Some researchers have labeled nomophobia, the fear of being without your phone, as 'the phobia of the 21st century.'

Researchers are studying roller coasters to improve mental health treatments

Scary rides stimulate our fight-or-flight response while simultaneously releasing feel-good endorphins like dopamine, serotonin, and oxytocin. Once we realize we're in a safe space, we can enjoy the ride and even feel confident and relieved by the accomplishment of overcoming a fearful feat.

Menopause can exacerbate anxiety

Some research shows that menopause can fuel anxiety and also that pre-existing anxiety can boost the chances of experiencing other menopause symptoms, including hot flashes, insomnia, and brain fog. But treatments including hormone replacement therapy, breathing exercises, and other forms of exercise can alleviate some of these symptoms.

Negative thinking spirals are often the result of uncertainty and anxiety

Psychologists suggest that a helpful way to deal with negative thinking is to remind oneself that setbacks can simply be setbacks, rather than a grand catastrophe. Positive self-talk, focusing on the factors we can control, and being altruistic are other tools that can help one escape negative thinking.

The positives of feeling stressed

Can brain scans help with processing trauma?

MRIs and brain monitoring therapies are becoming increasingly popular for those looking to process trauma and address mental health conditions, including PTSD and depression. This article details how these therapies quantify mental health, giving users another way to measure and manage their mental and emotional needs through brain mapping and other methods.

Some theorize that horror's artifice turns fear into enjoyment

The “excitation transfer theory” suggests that the unpleasant feelings a jump scare might elicit (like shortness of breath) are quickly relieved when the audience member remembers what they’re witnessing is fake.

Why 'spacing out' or dissociating may help reduce trauma awareness

Dissociation may have developed as a defense mechanism in the brain to help navigate intense emotional or physical situations by providing out-of-body experiences that put distance between the mind and the environment. However, in about 1.1% and 1.5% percent of the general population, a severe form of this separation can produce alternate identities, or alters.

Psychedelics interact with neurotransmitter systems to alter one's perception

LSD, psilocybin, and MDMA can suppress the brain's default mode network and enhance connectivity. Research shows that, when paired with therapy, psychedelics may help treat mental health conditions, including depression, addiction, and PTSD.

Some data shows cold showers can help with depression

An icy water exposure can lead to the release of norepinephrine, cortisol, dopamine, and other stress hormones that are beneficial, among other potential effects. Some data shows that this type of exposure can help combat depression symptoms among some patients, but more research is still needed. (Some users may encounter a paywall.)

Why so many people love roller coasters even though they’re scary

When a threat arises, it triggers our bodies to go into fight-or-flight mode and prepare for danger. However, when no obvious threat to our safety is present, this natural high can become enjoyable. Some people are more likely to enjoy these thrills based on factors like individual brain chemistry or physical health.

Misophonia is a neurological disorder where sounds trigger strong emotions

The phenomenon is characterized by decreased tolerance to specific sounds, such as heavy breathing, pen clicking, and water dripping, which trigger a fight-or-flight response. The resulting emotions, which can range from irritation and disgust to anxiety and fear, can be overwhelming and uncontrollable.

Using psychedelics to manage a cancer diagnosis

Dr. Roland Griffiths helped lead the revival of psychedelic research, often prescribing the use of psilocybin to address severe depression or anxiety in patients. This podcast explores how Griffiths leaned on his own career after being diagnosed with cancer and facing the prospect of death.

When common sounds become disturbing

Misophonia causes certain sounds to feel violating, triggering a "very visceral kind of experience" filled with extremely unpleasant emotions, including annoyance, anger, and disgust. A 2017 study found that people with misophonia have elevated activity in the brain's anterior insula—a region associated with interoception, emotional processing, and behavioral responses—when exposed to trigger sounds. Ongoing research suggests trigger sound context affects the severity and manifestation of the condition.

Our ancient fight-or-flight response may contribute to modern ailments

Many common modern diseases humans struggle with may in fact have their origins in our ancient fight-or-flight stress response. Long-term effects of the stress hormones cortisol and adrenaline—in this case, triggered by things like workplace stressors—can wreak havoc on the delicate internal balance of our organ systems.

Self-care can't fix burnout on its own

Steps such as exercise, breathing, mindful eating, and spending time with friends, can help alleviate the fight-or-flight mode response of the body to alleviate stress, but they don't fix the stressors causing the burnout. To address those, workplaces may need to consider how to better manage workloads and duties.

Consuming true crime media can increase stress and anxiety

Consuming true crime media can activate one's sympathetic nervous system, which controls the fight-or-flight response. Staying in this heightened state of vigilance can lead to stress-related illnesses, including hypertension, and mental conditions, including depression and anxiety. Additionally, people who actively consume crime news, whether they consider it to be entertainment or educational in nature, report being more fearful of crime, regardless of actual crime rates.

Stress evolved as a survival mechanism to keep humans alive

Stress activates the “fight-or-flight” response when we face threats. It’s triggered by the hypothalamus, which signals the release of adrenaline and cortisol, heightening awareness and energy. While acute stress helps in short bursts, chronic stress—persistent over time—can harm both physical and mental health, leading to conditions like hypertension, anxiety, or depression.

Support groups can offer insights into current and potential treatments

Beyond connecting with patients with similar experiences, support groups can also become centers for advocacy and for sharing research advances and medical experiences, including potential side effects from novel therapies or clinical trials.

Addressing psychological barriers to building wealth
