Epilepsy and photosensitivity: planning a theme park day

This page is for people with epilepsy, people who are sensitive to flashing lights, and the families who plan days out with them. You do not need a diagnosis to use it. It sets out what charities and research say, what parks publish about strobe and flashing effects, and a way of planning the day. It does not tell anyone what is safe for them or judge any ride. Where we found nothing, we say so.

In short

Photosensitive epilepsy is a minority of epilepsy. Epilepsy Society says around 3% of people with epilepsy; Epilepsy Action says 3 to 5 in every 100. Triggers differ from person to person, and many people with epilepsy are not photosensitive.
We found no research on theme parks or rides and seizures. The evidence comes from screens, laboratories and self-reports.
Parks publish very different things. Some list effects ride by ride, some say they cannot list every effect, and some publish nothing. Some parks warn that named attractions are not suitable for people with epilepsy; none assesses an individual.
A missing warning is not a clear all-clear. Parks say their lists are partial, and event nights such as Fright Fest add strobe at some parks.
Charities name tiredness, stress, alcohol and illness as triggers for some people, and say dehydration can make epilepsy worse.
Your own epilepsy team or GP can advise about you. The park decides on the day.

What can make theme parks hard, and what helps

There is little research on theme parks themselves. Our PubMed searches for roller coasters, amusement rides, theme parks and fairgrounds with seizures found nothing relevant. What follows comes from related settings (television, video games, laboratories, surveys) and health charities, and we say where it is thin or mixed.

How common it is

Epilepsy Society says that around 1 in 100 people has epilepsy and, of these, around 3% have photosensitive epilepsy, with most people who develop it between 7 and 19 years old (Epilepsy Society, photosensitive epilepsy (opens a new tab) ). Epilepsy Action says “only around 3 to 5 in every 100” people with epilepsy have it, and about 1 in 4000 people overall (Epilepsy Action, photosensitive epilepsy (opens a new tab) ). A 2008 journal article gives the same overall figure (Harding and Harding, 2008 (opens a new tab) ). Another review says clinicians need a careful individual history to identify triggers (Hanif and Musick, 2021 (opens a new tab) ).

What the charities say about visual triggers

Epilepsy Society describes photosensitive epilepsy as seizures triggered by certain rates of flashing lights or contrasting light and dark patterns, and says that triggers vary from person to person (Epilepsy Society (opens a new tab) ). Epilepsy Action lists examples such as strobe lighting at concerts or in clubs, rapid camera flashes, flickering light bulbs, and some Christmas lights and fireworks (Epilepsy Action (opens a new tab) ). An expert FAQ written by clinicians from national epilepsy societies adds that certain moving patterns can also provoke seizures (Kasteleijn-Nolst Trenité and colleagues, 2025 (opens a new tab) ). This is general information, not a rule about any ride, and no park we cover publishes a figure for an attraction.

Screens, 3D and virtual reality

Epilepsy Society says the risk of a 3D film triggering a seizure is about the same as a normal cinema film. It says of virtual reality that images generally flash too quickly to trigger a seizure, “However, the field of view is large and so more of the brain may be affected and this may trigger a seizure” (Epilepsy Society, re-opened 3 October 2026 (opens a new tab) ). The 2025 expert FAQ says virtual reality and 3D images “are not in themselves provocative, but their content can be”. Studies of games point the same way: a multicentre study of 352 people found “Games and programs with bright background or flashing images are specifically provocative” (Kasteleijn-Nolst Trenité and colleagues, 2002 (opens a new tab) ), and in a study of 94 children with epilepsy, those with photosensitivity or pattern sensitivity had a higher risk of EEG changes during video game play (Tekin and Edem, 2025 (opens a new tab) ). These are single screen studies. They say nothing about a ride vehicle, a 4D seat or a dark ride, and we found no research on those.

A 387-person laboratory study found that 14% of people referred after seizures in front of a television or game proved not to be photosensitive (Kasteleijn-Nolst Trenité and colleagues, 1999 (opens a new tab) ). Whether someone is photosensitive is a question for their clinician.

Other things charities name

Epilepsy Society’s list of possible triggers includes lack of sleep, stress, alcohol and drugs, and a high temperature due to infection or illness (Epilepsy Society, seizure triggers (opens a new tab) ). Epilepsy Action says many people report that tiredness or poor sleep can trigger seizures, and adds that “the things that trigger one person’s seizures might not affect someone else in the same way” (Epilepsy Action, seizure triggers (opens a new tab) ). The research on stress is mixed. A review says the most commonly noticed seizure increasers by far are stress, lack of sleep and fatigue (Kasteleijn-Nolst Trenité, 2012 (opens a new tab) ). Another says retrospective self-report studies show stress is the most common patient-perceived seizure precipitant, but prospective studies have yielded mixed results and there is no strong evidence of a close link for most people (Novakova and colleagues, 2013 (opens a new tab) ). In one study, 49% of 64 children with epilepsy said acute stress had precipitated seizures (van Campen and colleagues, 2015 (opens a new tab) ). A long, early, excited day can touch several, which is a reason to plan gently, not a prediction.

Heat

Epilepsy Society says: “Dehydration affects many processes in the body and can make epilepsy worse”, and advises keeping water with you and drinking more than normal in heat (Epilepsy Society, how to stay cool in the heat (opens a new tab) ). The research is not clear-cut. One 2026 diary study of children with drug-resistant epilepsy found that lower atmospheric pressure, greater atmospheric variation, lower temperatures and higher humidity may increase seizure risk (Arai and colleagues, 2026 (opens a new tab) ). We rely on the charity’s guidance and say “can”, not “will”. The same page says some people on certain anti-seizure medicines have been advised to restrict their fluids, so talk to your own doctor about drinking.

Worry about public places

A small Toronto survey (18 people) found that worry about injury, being unable to get help, and public settings raised anxiety for people with epilepsy and those affected (Tchao and colleagues, 2023 (opens a new tab) ). It is very small and describes anxiety, not what helps; telling someone in your group where first aid is, is our suggestion, not a finding.

What parks offer for this

We found no park scheme specifically for epilepsy. What parks publish is warnings, ride lists and restriction charts. A queue or boarding arrangement changes how you wait, not what a ride contains: see our guide to which access scheme suits you and our sensory and quieter days guide. These are the parks’ words as our profiles record them, not our view of any ride.

We recounted our 87 park profiles with a text search. 57 mention at least one of the words strobe, flashing, epilepsy, photosensitive or seizure, and 30 mention none. Some of the 57 only say the park publishes nothing, or use the word for evacuation alerts, so the table shows 12 whose profiles record something concrete, most detailed first. The other parks publish little or nothing we found; Heide Park’s profile, for example, records strobe light in places without saying where.

Absence from a list is not evidence of absence: the two Disney resorts say they cannot list every effect.

Before you go

Weeks ahead

Ask your own epilepsy team or GP what applies to you. The NHS suggests keeping a diary to identify things that might trigger a seizure, such as tiredness, stress, flashing lights, food or drink (NHS, epilepsy (opens a new tab) ).
Read the park’s own guide or warnings, noting the date on any PDF. Then ask the park in writing which attractions, shows, events and queues use strobe or flashing light (see the questions below).
Check whether your visit falls on an event night. Six Flags Over Texas, La Ronde and Warner Bros. Movie World each describe added strobe during their Fright Fest or Fright Nights events in the table above.

Days ahead

Re-check the park’s page, then build a picture schedule with the day planner and read a “what will happen” story. Our access timeline shows what to arrange and when.
Fill in an about me card with who to call and what helps. Leave out medical record numbers.
Use the packing checklist. Our medication guide covers what parks say about medicines.
Epilepsy Society’s travel page says to take medication in its original packaging with a copy of the prescription (Epilepsy Society, travel and holidays (opens a new tab) ); Epilepsy Action says the same for hand luggage (Epilepsy Action, travelling abroad (opens a new tab) ). Both are written for trips, not park days. Ask your clinician or pharmacist about your own medicines; we give no advice about timing or doses.

The night before

Charities list tiredness and poor sleep among triggers for some people, so aim for an unhurried morning.
Epilepsy Society says medicines should be kept in a cool place below 25C, out of hot cars and direct sunlight, and that a cool bag can help. Speak to a pharmacist about your own medicine (Epilepsy Society (opens a new tab) ).

On the day

Arrival. Find the first aid post on the map and tell one other adult where it is.
The first hour. Check any signs at ride entrances and ask staff about effects.
Breaks. Plan rests in shade. Epilepsy Society advises keeping water to hand in hot weather, unless your doctor has told you to restrict fluids.
An exit plan. Agree who will take someone out of a show or queue, and where to meet if separated.
If you meet an unexpected flashing light. Epilepsy Action’s advice is to cover one eye with the palm of your hand straight away, turn away or leave, and not to close your eyes, as this could cause a flicker effect (Epilepsy Action (opens a new tab) ). Epilepsy Society says covering one eye completely “can reduce the photosensitive effect”.

If someone has a seizure

This is the charities’ and the NHS’s published guidance, not a replacement for the person’s own care plan, which comes first. Epilepsy Society’s message for someone you do not know is Calm, Cushion, Call. It says most seizures happen suddenly, last a short time and stop by themselves; not to restrain the person or put anything in their mouth; to cushion the head; and to place them gently on their side afterwards (Epilepsy Society, first aid (opens a new tab) ). The NHS says to call 999 if it is the first time, if it lasts longer than usual for them or longer than 5 minutes when you do not know, if they do not recover as usual or have another seizure without recovering, or if they have had 3 or more seizures in 24 hours (NHS, epilepsy symptoms (opens a new tab) ).

Afterwards

Leave time to rest, as tiredness is on the charities’ trigger lists.
Tell us and the park what worked or what was missing, including any out-of-date park warning: give feedback. Please leave out personal and health details.

Questions to ask the park

Use our ask the park tool to draft a message. Useful questions:

Which attractions, shows, queues and events use strobe or flashing light, and where do you publish that? What is the date of the information?
Is there a ride guide, sensory guide or 360 degree video we can look at beforehand? See our sensory guide.
Can we leave a queue or show easily?
Do you have medicine storage, and what do you allow us to bring in? See our medication guide.

A note on this page

This page is desk research, not medical advice. It reports what charities, health bodies, research and parks publish, and it cannot say what is safe for any person. The park decides on the day what a visitor may do, and a clinician can advise about an individual’s situation. Park policies and pages change. Spotted something out of date? Tell us.
