In 2007 scientists found astraphobia is the third most prevalent phobia in the US. It can occur in people of any age. It occurs in many children, and should not be immediately identified as a phobia because children naturally go through many fears as they mature. Their fear of thunder and lightning cannot be considered a fully developed phobia unless it persists for more than six months. In this case, the child's phobia should be addressed, for it may become a serious problem in adulthood.

To lessen a child's fear during thunderstorms, the child can be distracted by games and activities. A bolder approach is to treat the storm as an entertainment; a fearless adult is an excellent role model for children.

Dogs may exhibit severe anxiety during thunderstorms; between 15 and 30 percent may be affected. Research confirms high levels of cortisol - a hormone associated with stress - affects dogs during and after thunderstorms. Remedies include behavioral therapies such as counter conditioning and desensitization, anti-anxiety medications, and Dog Appeasing Pheromone, a synthetic analogue of a hormone secreted by nursing canine mothers.

Studies have also shown that cats can be afraid of thunderstorms. Whilst it is very rare, cats have been known to hide under a table or behind a couch during a thunderstorm.

Generally if any animal is anxious during a thunderstorm or any similar, practically harmless event (e.g. fireworks display), it is advised to simply continue behaving normally, instead of attempting to comfort animals. Showing fearlessness is, arguably, the best method to "cure" the anxiety.

Specific phobias have a one-year prevalence of 8.7% in the USA with 21.9% of the cases being severe, 30.0% moderate and 48.1% mild. The usual age of onset is childhood to adolescence. Women are twice as likely to suffer from specific phobias as men.

Evolutionary psychology argues that infants or children develop specific phobias to things that could possibly harm them, so their phobias alert them to the danger.

The most common co-occurring disorder for children with a specific phobia is another anxiety disorder. Although comorbidity is frequent for children with specific phobias, it tends to be lower than for other anxiety disorders.

Onset is typically between 7 and 9 years of age. Specific phobias can occur at any age but seem to peak between 10 and 13 years of age.

Like astraphobia, lilapsophobia is a common fear for children, although less common. Because children are just learning to distinguish between fantasy and reality, major storm broadcasts on television or discussion by parents can cause fear that the storm is coming with a tornadic potential or a hurricane.

Because fear is a part of normal child development, this phobia is not diagnosed unless if persisted for more than six months. Parents should conquer the child's fear by telling them how rare the major storms that hit hometown area are.

Lilapsophobes spend a lot of time watching the weather or checking weather online to keep an eye out for oncoming storms. When a storm hits, sufferers either watch for severe weather alerts constantly or take cover, like under the bed or in the windowless room. In the extreme cases, sufferers take tornado shelter as soon as rain starts falling, usually in the basement or storm shelter. Sufferers who have weather radio or mobile phones can watch the radar and alerts using it while hiding.

A specific phobia is any kind of anxiety disorder that amounts to an unreasonable or irrational fear related to exposure to specific objects or situations. As a result, the affected person tends to avoid contact with the objects or situations and, in severe cases, any mention or depiction of them. The fear can, in fact, be disabling to their daily lives.

The fear or anxiety may be triggered both by the presence and the anticipation of the specific object or situation. A person who encounters that of which they are phobic will often show signs of fear or express discomfort. In some cases, it can result in a panic attack. In most adults, the person may logically know the fear is unreasonable but still find it difficult to control the anxiety. Thus, this condition may significantly impair the person's functioning and even physical health.

Specific phobia affects up to 12% of people at some point in their life.
