Why Do Lights Cause Seizures
Certain patterns of light flashing bright lights at particular frequencies synchronize cells within the visual cortex. If the neurons then fire through their networks at too high a level, they can recruit other neurons into a hyper-synchronous discharge. That’s what happens in the brain during a seizure.
Avoiding Negative Effects On Kids
Here are a few steps you can take to limit the negative effects of watching television for kids.
- Do your research and select the most appropriate shows for your children. Do not select a show just because they say the intended audience is children. Ensure that the content is appropriate for your child’s age and has a good tone and pace. It is better to select shows with shorter duration. Moreover, you should not let your kids watch ads.
- Limit screen time for kids. If your child is between two and five years of age, do not let them spend more than 32 hours a week in front of TV. Do not let them watch TV during mealtime and do not put TV in their bedroom. Do not take TV as a babysitter leaving your kids unattended may exposed them to inappropriate content being shown on TV. Be sure to lay out TV time rules and take steps to ensure that your kids follow those rules.
- Making it a family activity. It means that instead of letting your kids watch TV alone, you should be there and make it a fun family activity. This will keep your kids from taking TV as a way to kill the time.

Paediatric specialist, Associate Professor Pirjo Anttila, also cautionsparents on the dangers of IT overdose for kids. She recommends a maximum of twohours screen time per day, stressing that being static and immobile for longperiods of time has a well-documented detrimental effect on health and wellbeing.
Furthermore, sleep disruption and abnormal nocturnal rhythms are the bane ofthe IT generation.
The brain remains in active mode, if you watch the computer or TV beforegoing to sleep, explains Anttila. The recommendation is to put all equipment away half an hour before goingto sleep. This way sleep will be peaceful.

What Are The Kinds Of Headaches
The most common type of headache is a tension, or muscle-contraction, headache. This happens when stressed-out head or neck muscles keep squeezing too hard. When you get this kind of headache, the pain is usually dull and constant. It might feel as though something is pressing or squeezing on the front, back, or both sides of your head.
Pain that’s especially sharp and throbbing can be a sign of a different kind of headache called a migraine . Migraine headaches aren’t as common as tension headaches, especially in kids, but they can still happen. Sometimes, just before a migraine happens, the person sees wavy lines or bright spots of light. This is called an aura . Also, kids who get migraines often feel sick to their stomachs and sometimes throw up.

For people plagued by migraines, it can be frustrating that others don’t suffer from them, leading many to wonder ‘why me’.
Dr Day explained that to answer the ‘why me’ question, genetics need to be considered.
A previous study found that there are 38 regions of the genome that are connected to migraines – meaning that these areas can reveal how each individual is predisposed to migraines.
While this is a factor, there are also identifiable triggers when it comes to a migraine.
Dr Day said: “Common triggers for migraine include poor sleep, excess use of caffeine, missing meals and the use of artificial sweeteners.
“Other risk factors for migraine include obesity, stress, alcohol consumption, hormonal changes and excessive use of pain medication.
“Individuals with a genetic susceptibility to migraine may continue to experience migraine symptoms if they continue to be exposed to environmental triggers, such as those listed above.”

How Common Are Headaches From Computer Screens
It is likely that we all have dealt with the following scenario at one time or another:
The unfortunately truth is that headaches or migraine attacks from the computer screen are a common occurrence, but researchers have had a difficult time pinpointing just how widespread it is for the general population. Most often it is linked to computer vision syndrome, or CVS for short, which specifically refers to visual and other symptoms that result from screen exposure and which may affect as many as 90% of computer users.2
Among those with CVS symptoms, headache is frequently cited as the most prevalenteven though, ironically, it is not directly related to the eye. Researchers from across the globe have found that between 19% to 53% of those with extended exposure to their PC or laptop screen suffer headaches as a frequent side effect in many cases, recurring headache symptoms lasted a week or more.1,4,10 Workers who specifically use the computer as a primary function of their job have also been found to have more headache episodes, although just a few hours of constant use for an extended time period can have the same effect.1,3
What Can I Do To Reduce These Symptoms
When watching TV, especially at night, there are a few tricks that can help reduce the amount of blue light exposure.
- Turn down the lights in the room this will help you to see the screen better after the second step, which is
- Turn down the brightness display on your TV. Most TVs these days have a wide range of brightness settings you can adjust. You can even save some to set it at your ideal brightness for the nighttime hours with the push of a button
- Wear blue light filtering lenses while watching screens. BluTech Lenses filter blue light at 455 nm, which is where it is most harmful.
Coeliac Disease And Gluten Sensitivity
Coeliac disease is a serious condition where a persons immune system reacts when they eat gluten and causes damage to the lining of their gut. When this happens, they have symptoms such as diarrhoea, bloating, vomiting and stomach cramps. There can also be serious complications if it is not treated, such as anaemia. There is no cure for coeliac disease and people with it need to avoid gluten all their life.
There have been studies into the link between coeliac disease and migraine. There is no evidence to suggest that coeliac disease causes migraine. It is thought that if people with coeliac disease and migraine follow a gluten-free diet, this may help with both of their conditions.
Gluten sensitivity is when a person has a bad reaction if they eat gluten. They may have similar symptoms to coeliac disease, but there is no damage to the lining of their gut or the risk of serious complications that can happen with coeliac disease.
Gluten is found in foods that contain wheat, barley or rye. These include pasta, bread, cakes, some sauces and most ready meals.
One of the symptoms of gluten sensitivity is headache. But there is no evidence that gluten sensitivity causes migraine. However, if you are sensitive to gluten, you may find that if you eat food containing gluten, it makes migraine attacks more likely or the symptoms more painful.
When Should I Go To A Doctor
Headaches are very rarely a sign of anything serious. Headache triggers such as eating certain foods, being stressed out, or not getting enough sleep are much more likely causes of headaches in kids. Or sometimes, there’s no obvious reason at all.
Still, there are times when your mom or dad should talk with the doctor about your headaches:
- when a headache is particularly painful
- when a headache doesn’t go away easily
- when a headache follows an injury, such as hitting your head
- when your vision is affected
- when you feel tingling sensations
- when you just don’t seem like your usual self
- when headaches occur once a month or more
- when headaches cause you to miss school
A doctor can help you and your parents figure out why you’re getting headaches and might be able to help you keep them from happening so often. Sometimes relaxation exercises or changes in diet or sleeping habits are all that’s needed. If necessary, a doctor also can prescribe medication to control headaches.
If you’re bothered by headaches, you don’t have to put up with the pain. Sometimes relief is just a nap away. Other times, seeing a doctor may be necessary. But there’s almost always something that you, your parents, and your doctor can do to help.

What Should You Do
Once you know the negative effects of watching television, it is important to take steps to bring things back to normal. Here are a few simple tips to try:
- TV is bad for your health because it makes you sit still for hours upon hours. Simply include exercise into your viewing routine you can do squats and lunges during commercial breaks.
- Avoid unhealthy snacks. When watching TV, you should never go for unhealthy snacks. It is better to keep a bowl of fresh fruit by your side than going for anything laden with salt and sugar.
- Set a timetable. It is better to set a timer and ensure that you do not spend more than an hour in front of your TV. Setting a timer will help you realize that you have watched for long enough and now it is time to turn it off.
Should You Buy An Oled Tv
Definitely yes. OLED TVs provide amazing picture quality and brightness. Its immersive display has won appreciation from all quarters and is being adopted across all screen sizes from mobile phones to large TVs. However, if you are concerned whether it will cause you headaches or eye strain too, it is worth remembering that only a small percentage of users have highlighted this issue. As has been explained above, the tolerance to image flickering varies from individual to individual and most viewers shall never face this issue.
Further, I would suggest that if you do intend to buy an OLED TV, please do a live demo of the model before purchasing. If that is not possible, you may test whether image flickering on other OLED screens bothers you. Most flagship mobile phones today boast an OLED screen with noticeable image flickering at lower brightness.

Ideal Tv Viewing Distance And Position
Some eye care professionals recommend sitting approximately eight to 10 feet away from the TV screen. The general rule of thumb is to be at least five times the distance from the screen as the screen is wide. For example, if your television is 32 inches wide, the optimal viewing distance is 160 inches or about 13 feet.
However, most optometrists and ophthalmologists agree that the best distance for television viewing is the distance that feels most comfortable for you. As long as you can see the screen clearly without experiencing discomfort, the distance is probably correct.
Besides viewing distance, the position of your television in relation to where you are sitting is also important for preventing eye strain.
Whether you hang your TV on the wall or set it on a tabletop, try to position it at eye level or lower to prevent straining your vertical eye muscles or your neck. Constantly forcing your eyes to look up will eventually cause the eye muscles to fatigue.
Lastly, as different types of screens have become more common in homes, the American Optometric Association promotes the 20-20-20 rule. They suggest that you take a 20-second break every 20 minutes to view a distant object that is 20 feet away. So, for example, if you watch your favorite movie or TV show on your laptop, take regular breaks to avoid eye strain.

Eye Problems Caused By Too Much Watching Of The Television
ByKarlhans Che | Submitted On July 24, 2010
The human eye is made up of the LENS that collects and focuses light to the RETINA at the back of the eye, the PUPIL that determines how much light is let into the eye and the CORNEA is the protective tissue that covers the front of the eye.
These part of the eye and many others I have not mentioned work as a team to collect light to back of the eye and to the brain for interpretation before we can actually appreciate what we have seen. Any damage in one of these important eye components can completely or partially impair eye vision.
One fundamental cause of bad vision is too much exposure of strong light to the eyes. Today, the television is accounting for serious eye defects and I will share three reasons why too much watch of the television can damage your vision.
Strong light from the TV: Watching the television is enough exposure of the eyes to a constant light source. Strong light from the television can cause damage to the cornea as well as the lens. In most cases you can feel like there is sand in the eyes and constant pain when eyes encounter some light of particular wave lengths.
Eye complications are mostly solved using glasses, but for those who do not like glasses, learn how to correct your vision without the use of glasses here. .
