No Gaming Before Bedtime

Many kids and teens love gaming—but playing right before bed can wreck sleep. Even passive gaming (watching streams or videos) can overstimulate the brain, keeping kids wired instead of relaxed.

Let’s look at why gaming delays sleep—and how to create a gaming cut-off time without a battle.

Why It Matters

• Gaming keeps adrenaline and dopamine levels high, making it harder to wind down.

• Fast-paced games increase heart rate and alertness.

• Studies show that kids who game before bed take 40% longer to fall asleep and wake up more during the night.

What You Need to Know

💡 How to set a “gaming curfew” that works

✔ Set a fixed cut-off time (at least 60 minutes before bed)

✔ Swap gaming for a low-stimulation activity (reading, stretching, listening to music)

✔ Encourage earlier gaming sessions so kids don’t feel they’re missing out

How to Implement Change

Tonight’s Action Step: Try a “no-gaming before bed” rule tonight. Have a relaxing activity ready as a replacement so it’s easier for kids to transition!

Managing Screen Time Before Bedtime

It’s 9:30pm, and your child is still wide awake, scrolling through their phone or playing one last round of a game. You finally convince them to put it down—but when they do, they can’t seem to fall asleep. Sound familiar?

Screens before bed are one of the biggest culprits behind poor sleep. The good news? There’s a simple way to fix it.

Why It Matters

Even 30 minutes of screen time before bed can:

– Delay melatonin (the sleep hormone) by up to 90 minutes

– Trick the brain into thinking it’s daytime, keeping it in “alert” mode

– Reduce sleep quality, leading to more night wake-ups

For teens, the impact is even greater. Studies show that 70% of teenagers don’t get enough sleep—largely due to screen use before bed.

What You Need to Know

Why does screen time delay sleep?
✔ Blue light from screens suppresses melatonin production, making it harder to wind down.
✔ Social media and gaming stimulate the brain, keeping it active rather than relaxed.

How much time is needed to reset?
✔ Ideally, no screens at least 60 minutes before bed.
✔ If that feels too hard, start with 30 minutes and work up.

What works instead?
✔ Encourage screen-free wind-down activities: reading, listening to music, or journaling.
✔ Set up a charging station away from the bedroom—so screens don’t become a late-night temptation.

How to Implement Change

Tonight’s Action Step: Set a “screen curfew” tonight:

Choose a time when all screens go off (30-60 minutes before bed).

Bonus Tip: If your child resists, frame it as a “sleep experiment” to see if they wake up feeling more rested.

How a Simple 5-Minute Chat Can Improve Sleep

Have you ever noticed that kids bring up their biggest worries right before bed? That’s because the brain processes emotions before sleep—and if those emotions are unsettled, sleep quality suffers.

A 5-minute bedtime check-in can be life-changing for sleep, helping your child release stress, process emotions, and feel secure before drifting off.

Why It Matters

Unspoken worries = restless nights.

Stress hormones (like cortisol) stay elevated, preventing deep sleep.

Night-time anxiety delays melatonin, making sleep harder.

A bedtime check-in reassures kids and teens, creating a sense of emotional safety.

What You Need to Know

Try these simple bedtime prompts:

✔ “What was your favourite part of today?”

✔ “Did anything make you feel worried or stressed?”

✔ “What’s one thing you’re looking forward to tomorrow?”

For teens, frame it as “unloading their mind” before sleep, so they can wake up with mental clarity.

How to Implement Change

Tonight’s Action Step: Try a 5-minute bedtime check-in tonight.

Bonus Tip: Keep it casual. Lying in bed, dimming the lights, and just listening creates a safe space for your child to unwind.

Is Sugar Ruining Your Child’s Sleep?

Ever noticed that some nights your child just can’t switch off? Or maybe they wake up during the night, restless and alert? The culprit might be something surprising: sugar.

What your child eats before bed directly impacts their sleep quality. Many snacks marketed as “healthy” spike blood sugar levels, causing an energy crash that disrupts deep sleep.

Let’s explore how sugar hijacks your child’s sleep—and what to do instead.

Why It Matters

Sugar is not just an energy booster—it’s a sleep disruptor. Here’s why:

✔ Sugar delays melatonin production:
Melatonin is the hormone that signals sleep. When blood sugar levels spike—especially in the evening—melatonin release is suppressed, making it harder for your child to feel sleepy at bedtime.
✔ Blood sugar crashes wake kids up at night:
After a sugar spike comes a crash. The body then releases stress hormones like cortisol and adrenaline to restore blood sugar balance—leading to night waking and early morning grogginess.
✔ Teens who consume sugar before bed sleep 30-60 minutes less:
Research shows that teens who drink sugary sodas or eat high-carb snacks before bed get significantly less deep sleep and wake up feeling more fatigued.

What You Need to Know

The Glycaemic Load Connection:

Foods high on the glycaemic index (GI) (like white bread, pastries, or refined carbs) cause rapid spikes and crashes in blood sugar.

Lower-GI foods (like nuts, seeds, and proteins) provide steady energy without disturbing sleep.

Even “healthy” foods can contain hidden sugars. Watch out for:

• Flavoured yogurts (some contain as much sugar as ice cream!)
• Fruit juices & smoothies (natural but still high in sugar)
• Granola bars & “healthy” cereals (often loaded with added sugar)
• Dried fruit & raisins (high in concentrated sugars, low in fibre)

How to Implement Change

Tonight’s Action Step

Swap out sugary bedtime snacks for a sleep-friendly alternative:

✔ Greek yogurt with a handful of berries (protein + calcium for relaxation)
✔ Almond butter on oatcakes (healthy fats + slow-release carbs for stable blood sugar)
✔ A small handful of nuts (rich in magnesium, which promotes relaxation)

A Simple Bedtime Routine for Deeper Sleep

Let’s look deeper into constructing a consistent bedtime routine. Consistency with a sleep-wake cycle is one of the most powerful tools for helping your child or teen sleep better. Without a structured wind-down, the brain stays in “go mode”—leading to restless nights and groggy mornings.

Why It Matters

• Kids and teens with structured bedtime routines fall asleep faster and sleep longer.

• A predictable routine reduces bedtime resistance and night time anxiety.

• Over time, the brain associates the routine with sleep, making it easier to relax.

What You Need to Know

A good bedtime routine should last 30-45 minutes and include low-stimulation activities that help transition from awake to asleep.

For Younger Kids (4-10):

✔ Dim the lights to signal sleep.
✔ Bedtime story or quiet play (avoid screens).
✔ Gentle cuddles or calming music before sleep.

For Tweens & Teens (11-17):

✔ No screens 30-60 mins before bed (more on this later!).
✔ Encourage a wind-down habit (reading, journaling, stretching).
✔ Keep bedtime consistent—even on weekends.

How to Implement Change

Tonight’s Action Step

Create a simple bedtime routine:

• Choose 3 calming activities before bed (e.g., bath, book, breathing).

• Stick with it for 7 nights and notice the difference!

Optimising your child’s sleep starts today!

Welcome to COGNITION for Smart Kids and Teens. Starting now and in the weeks that follow, we’re going to guide you in taking simple steps to help your child sleep better and regulate their mood.

Better sleep is one of the biggest game-changers for mood, focus and resilience.

Why It Matters

Poor sleep isn’t just about feeling tired—it impacts your child’s ability to focus, regulate emotions, and even learn new things. Studies show that kids and teens who don’t get enough sleep struggle more with anxiety, memory, and problem-solving.

If your child or teen is waking up groggy, struggling with mood swings, or feeling wired at night, their sleep routine needs a reset. The good news? Small changes with their evening routine can make a big difference and we going to give you some ideas of what to try differently.

What You Need to Know

Breaking the “Tired but Wired” Cycle
When sleep is poor, stress levels rise, making it even harder to fall asleep the next night. This cycle creates overtired but restless kids—wide-eyed at night, exhausted in the morning.

The Fix? The brain loves routine. One of the fastest ways to improve sleep quality is setting a consistent bedtime and pre-sleep routine—even for teenagers (who may resist it at first!).

How to Implement Change

Tonight’s Step: Choose a simple, achievable sleep goal to focus on such as:

✔ For younger kids (4-10): Set a fixed bedtime and wake-up time to regulate their body clock.
✔ For tweens & teens (11-17): Reduce screens at least 30 minutes before bed and swap for a wind-down habit (reading, music, journaling).

Write down the sleep goal, and if your child is old enough, involve them in negotiating one. You can keep a sleep journal to track small wins over time!

Easing Constipation

If your child struggles to go to the toilet regularly, they’re not alone—constipation is a common issue. But it doesn’t have to be! With the right support, your child can feel lighter, happier, and more energised.

Popular advice for constipation is to eat more fibre-rich foods such as wholegrains. These are more fad than fact since there is no consistent evidence that fibre works. In fact, in some studies show having more fibre makes matters worse, not better!

The Science:

• In a study of 63 adults who suffered from chronic constipation and were on a high fibre diet and/or were taking fibre supplements, 41 were put on a no-fibre diet, 16 on a reduced fibre diet and 4 remained on their high fibre diet.

• Of those put on the no-fibre diet, frequency went from once every 3.75 days to once a day. Those on the reduced fibre diet went from once every 4.19 days to every 1.9 days while there was no change in those who stayed on their high fibre diet.

This study is one of quite a few which show no benefit, or worsening on a high fibre diet. A review on studies treating IBS sufferers with high fibre diets shows much the same thing, with an increase in regular ‘insoluble’ fibres found in wholegrain wheat, probably making matters worse not better. Linseed or flax seeds also contains insoluble lignins. Evidence of their benefit in studies of people with IBS is rather thin.

It’s soluble fibre your child needs

The good news! Most studies do, however, show a benefit for ‘soluble’ fibres which is what you find in oats and chia seeds.

• People given soluble fibres in studies were almost twice as likely to report benefit, with increased frequency and ease, over those on a placebo. What you want are fibres that absorb the most water, thus bulking up and lightening the contents in the colon.

• One way to increase your child’s intake of soluble fibres is to have a dessertspoon of chia seeds a day or a heaped teaspoon for younger children less than age 5. Another is to eat whole oat products. ‘Rough’ oatcakes have more fibre than ‘fine’ oatcakes or crackers. If you read the label it will tell you how much fibre there is – and how much sugar. The more fibre, the less sugar.

• Soluble fibres are also in vegetables, although somewhat destroyed by heat and hence prolonged cooking. Hence, raw or lightly cooked, steamed or steam-fried vegetables are best. They behave quite differently to, for example, wheat fibre.

Natural foods stay soft in the digestive tract because they contain fibres which absorb water and expand inside the digestive tract. Fruits and vegetables naturally contain a lot of water in themselves. Provided they are prepared properly, whole grains, such as oats and rice, absorb water and provide watery bulk for the digestive tract. Given that we are literally 65 per cent water, it makes sense to eat foods with a high water content.

Solving the Riddle of Bloating and IBS

Does your child experience bloating? The three most effective ways to reduce bloating are eliminating food intolerances, gluten-free or modern wheat-free diets (some need to avoid all grains), and supplementing digestive enzymes and probiotics. Let’s examine the evidence.

Bloating, IBS and Food Intolerances

Several studies have shown that those with IBS have higher levels of food-specific IgG antibodies in their blood – much more than in “healthy” subjects. Knowing that IBS sufferers have significantly raised levels of IgG antibodies to specific foods, researchers at the University of South Manchester (1) tested 150 IBS sufferers with a YorkTest food specific IgG antibody test and then gave their doctors either the real or fake results. Only those following a diet eliminating their food intolerances had relief from IBS symptoms of bloating and abdominal pain. What’s more, those who stuck to it most strictly had the best results. Levels of compliance, on the other hand, didn’t make a difference in those on the sham diets.

Gluten and Modern vs Ancient Wheat

The most common food linked to bloating is wheat. The increasing prevalence of non-celiac gluten sensitivity is raising questions regarding what people are reacting to and why. A recent Dutch survey of 785 people self-reporting gluten sensitivity found that only two, on testing, had coeliac disease. Symptoms reported included bloating (74%), abdominal discomfort (49%) and flatulence (47%). These symptoms are extremely common in children.

One trial tested the effects of a gluten-free or placebo diet (giving gluten containing or gluten-free bread) for four weeks on 60 IBS sufferers. There was a strong reduction in bloating and abdominal pain in those on the gluten-free versus placebo diet, and a return of symptoms on reintroducing gluten.

Professor Francesco Sofi, at the University of Florence, had a hunch that it might not be wheat per se, but rather that gluten and other proteins have been changed in modern wheat compared to that of ancient wheat, and this is driving bloating and IBS. To test this theory, he gave IBS sufferers foods (bread, pasta, biscuits) made from either modern wheat or ancient organic Kamut® ‘khorosan’ wheat for six weeks, randomly assigned. This is the same wheat that was eaten thousands of years ago which is genetically much simpler than modern wheat which has been genetically altered through hybridisation.

During the modern-wheat weeks they had no improvement. However, when they were unknowingly eating Kamut, everything got better. They reported significantly less bloating, abdominal pain, irregularity and tiredness. Remarkably, every single person in the study reported benefit. Also, blood markers of inflammation all reduced by a third.

Digestive Enzymes and Probiotics

Every day the child’s body produces a staggering litre of digestive juices containing enzymes. Infants make less and older children make more depending on the size of their stomach.

The most common offending foods for wind are beans, lentils and other pulses, which require alpha-galactosidase for their digestion; and greens, especially cruciferous vegetables (cabbage, Brussels sprouts, cauliflower), which require amyloglucosidase (also called glucoamylase). Certain others generate more gas, including turnips, leeks, onions and garlic. Some people produce insufficient amounts of the enzyme, alpha-galactosidase, or amyloglucosidase, the enzyme that digest greens.

It is not easy, or perhaps necessary, to test if a person is a poor producer of digestive enzymes. The simplest ‘test’ is just to give a person a comprehensive digestive enzyme supplement containing all the above enzymes, plus lactase, amylase, protease and lipase, being the key digestive enzymes if these symptoms are present.

It All Starts with a Smile: Why Dental Health Matters for Kids

We all want our children to have great teeth and know that too much sugar, including fruit juice, is a driver for tooth decay, but what has dental hygiene got to do with the mind?

Although it’s at the other end of the lifespan, and recent in terms of the science, the discovery that certain harmful bacteria that multiply in the mouth with bad dental hygiene (not brushing and flossing as well as eating too much sugar) leading to gum disease, could actually be a contributary cause of Alzheimer’s should make all parents wake up to the importance of instilling good dental habits and diet in children.

As many as 90% of those with Alzheimer’s had high levels of these pathogenic mouth bacteria, p.gingivalis being one of them. It’s part of a wave of research showing that pathogenic microbes in the gut, and inhaled from mould, can get into the brain and have disastrous effects. There’s a whole range of insidious symptoms from frequent infections and breathing problems as well as cognitive problems and digestive disturbances, that can result from the wrong microbes, from the gut or inhaled, getting into the brain.

This highlights the need to instil in children good diet and dental habits.

In terms of diet, it is so much better to crunch on a juice apple, full of fibre, which actually helps to clean the teeth, than suck on a carton of juice or water bottle full of juice. So, the first action is to have your child eat fruit rather than drink it and drink water rather than juice when thirsty.

In some Scandinavian countries children are given a xylitol sweet on arrival at school. Why? Xylitol, the crystalline version of xylose, which is a predominant sugar in berries, protects children from tooth decay. The reason for this is that harmful bacteria in the mouth, which then attach to teeth and make acids which root the teeth, can’t stick to teeth when they are exposed to xylitol. That’s why xylitol is used in some toothpastes, chewing gums and mouth washes.

Steps for good dental hygiene:

• Brushing the teeth. This needs to become a twice daily routine. Either on waking or even better after breakfast, and before bed.

• Flossing is a bit harder with young kids but, as soon as teeth are touching, it helps to dislodge bacteria. While dentists say every day certainly flossing your children’s teeth once a week is a minimum.

How to prevent tooth decay

Besides from the obvious dental hygiene habits like brushing teeth and flossing the key for your children is to avoid sugar, in all its forms, including the seemingly ‘natural’ alternatives to regular cane sugar, as well as focusing on a diet that helps to stabilise blood sugar levels. There is one exception, however, which is xylitol.

Here are some examples of sugar substitutes to be aware of and avoid:

• Dextrose, Fructose, Galactose, Glucose, Lactose, Maltose, Sucrose, Beet sugar, Cane juice crystals, Coconut sugar, Corn syrup solids, Crystalline fructose, Date sugar, Dextrin, Diastatic malt, Ethyl maltol, Florida crystals, Glucose syrup solids, Grape concentrate, Maltodextrin, Agave Nectar/Syrup, Barley malt, Blackstrap molasses, Brown rice syrup, Buttered sugar/buttercream, Caramel, Carob syrup, Corn syrup, Evaporated cane juice, Fruit juice, Fruit juice concentrate, Golden syrup, High-Fructose Corn Syrup (HFCS), Honey, Invert sugar, Malt syrup, Maple syrup, Molasses, Rice syrup, Refiner’s syrup, Sorghum syrup, Treacle.

• Also avoid fruit juices and in particular shop-bought fruit juices, which often contain fruit concentrates. Whilst fruit is a natural form of sugar, fruit juices often contain the juice of the fruit without its pulp or fibre. This means that it is very quickly converted into glucose (sugar) in the body, which leads to blood sugar imbalances and eventually insulin resistance, if consumed too frequently.

• Eat a diet that mainly consists of foods in their natural form, paying attention to meals that prioritise protein such as in pulses, eggs, poultry, meat and fish, along with a wide variety of vegetables and healthy fats found in nuts and seeds, avocado and extra virgin olive oil.

• Switch refined carbohydrates for complex carbohydrates – these are foods that are naturally high in fibre such as whole grains like brown rice, wholemeal bread, quinoa and oats, as well as starchy vegetables like beetroot, sweet potatoes, carrots, pumpkin and butternut squash.

The Gut-Brain reaction: Finding your child’s food intolerances

If your child is suffering from bloating, belching, indigestion, heartburn, abdominal pain, IBS and any other digestive complaint or brain fog and headaches but after meals, you might be wondering if there’s something they are eating that they might be intolerant to.

A good starting point would be to give them a digestive enzyme supplement that includes probiotics, just to rule out indigestion and dysbiosis. Taking this with each meal for three days should make a difference.

If it doesn’t then the next most likely contributor to their digestive problems is a food intolerance. Allergies are caused by the immune system producing antibodies that ‘attack’ certain food proteins because it considers them as aliens. The most extreme type of allergic reaction involves a type of antibody called IgE. There is a test for this, in which a drop of potential allergens are put on a pin prick on the arm, if you react you get a red wheal. This immediate reaction, within ten minutes, is an IgE reaction. IgE allergy can also be tested from a blood sample.

But many reactions against food involve a different kind of antibody called IgG. Most people call these food intolerances even though they do fit the bill for the definition of an allergic reaction. IgG reactions don’t occur immediately so it isn’t always easy to know what you react to. For this reason, it is worth having a test to find out what you may be reacting to. This can be done from a tiny amount of blood, collectable with a home test kit. The leading laboratory is called www.yorktest.com. They send you a kit, you prick your finger (it isn’t painful) and send them the blood as instructed. They then measure the presence of IgG antibodies in your blood and give you a report that tells you how strongly your immune system is reacting against which foods. (If you use this discount code, FFB10 (FFB10US in the US) they’ll give you a 10% discount and match it with a donation to help our research.)

Healing the gut

If you decide to have your child tested, the first step is to avoid those foods that they react strongly to – the ‘red’ foods. You can ‘rotate’ those foods which produce a mild reaction – the amber foods – which means eaten not more than every five days. (If you eat a reactive food every day your level of reactivity builds up.) Yorktest include a session with a nutritional therapist by phone, who can help you do it correctly.

The good news is that IgG antibody reactions often go away with strict avoidance of the food for 3 to 4 months and healing of the gut. The same is not true for IgE based reactions. We often develop food intolerances because the gut wall becomes inflamed or damaged allowing incompletely digested food proteins to enter the body and bloodstream. The gut wall is also damaged by alcohol, painkillers, too much coffee and fried foods.

Certain foods irritate the gut wall. An example is wheat, containing gliadin. This is why a lot of people are somewhat intolerant of wheat.

Fortunately, the cells that line the gut wall heal and replenish very quickly, especially when you feed them an amino acid called l-glutamine. So, supplementing l-glutamine can speed up gut healing. Some digestive enzyme supplements contain a little glutamine. If you want to heal a ‘leaky’ gut give your child 5 grams (a heaped teaspoon) of glutamine powder in cold water (hot water destroys this amino acid) last thing at night or at least half an hour before eating.

In summary, to reduce your child’s immune sensitivity to foods and restore gut health

• Identify and avoid your food intolerances
• Take digestive enzymes with each meal for two weeks afterwards
• Take probiotics daily for two weeks afterwards
• Take glutamine daily for two weeks afterwards

Some digestive supplements provide all three – digestive enzymes, probiotics and glutamine – in one.
