Does eating cheese before bed cause nightmares? Doctor reveals the connection
QUESTION: Dear Dr Zac, I've heard this crazy rumor that eating cheese before bed can give you nightmares. I love eating cheese and crackers after dinner while a watch a good movie, but lately, I've been waking up from some pretty whack dreams. – Effie, 29, Bankstown, NSW

ANSWER: Double cream or troubled dreams? Let's slice into the truth.
Blame it on Charles Dickens. In 'A Christmas Carol,' Ebenezer Scrooge famously blames his ghostly visions on 'a crumb of cheese.'
But is your cheesy snack really to blame?

In 2005, the British Cheese Board set out to investigate. They gave 200 people different cheeses before bed and tracked their dreams. The verdict? No link between cheese and nightmares.
In fact, some cheeses — especially cheddar — were even associated with more pleasant dreams.
Brie-lliant, you said?
Still, plenty of people swear their dreams go wild after a cheese-fueled snack. So let's look at what might really be happening under the rind.

Cheese contains tyramine, a naturally occurring compound that, in theory, can stimulate the brain by triggering the release of norepinephrine — a chemical linked to alertness, and potentially, disrupted sleep.
But here's the thing:
• Most people eat 30–50 grams of cheese per sitting — just a few slices or cubes.

• That delivers only a tiny amount of tyramine — nowhere near enough to whip your brain into dream overdrive.
• And unless you're taking a rare class of antidepressants called MAO inhibitors, your body breaks it down just fine.
In other words, your late-night snack is far more likely to be creamy than dreamy.
And let's not forget: cheese is rarely eaten solo.
If you're working your way through a cheese board with a few glasses of wine during that movie, alcohol could be the issue.

Alcohol: it's a major sleep disrupter:
• It suppresses REM sleep early on, then triggers REM rebound, leading to vivid, intense dreams.

• The result? You wake feeling like you've been drowning in an ocean of fondue all night.
So if your dreams are melting into madness, it might not be the blue … but the red, rose, or white that's at the wheel.
Additionally, high-fat meals — especially those rich in saturated fats — can throw off your sleep. Studies show these foods are linked to lighter, more fragmented sleep and reduced deep sleep, which can lead to frequent wakings and more vivid or unsettling dreams.
Bottom line?

Unless you're on a rare medication that affects how you process tyramine, your cheese is off the hook.
If anything, it's the rich meals, late timing, and alcohol pairings that stir up those surreal night narratives.
And remember: Cheese is best paired with unpressed grapes and an early night.
Sweet dreams — and yes, you can still keep your crackers.

‘Sleeping Prince' of Saudi Arabia dead at 36 after 20-year coma
A Saudi Arabian royal who spent more than two decades in a coma after a horror car crash in London has died at the age of 36. Prince Al-Waleed bin Khalid Al-Saud suffered a brain haemorrhage and internal bleeding in the horrific accident in 2005, when he was just 15 years old. Widely known as the 'Sleeping Prince', he was kept on a ventilator in hospital – but never regained full consciousness. Prince Al-Waleed was the eldest son of Prince Khaled bin Talal Al Saud, who confirmed his death in a heartbreaking post on X today. Quoting a verse from the Quran, he wrote: 'With hearts believing in Allah's will and decree, and with deep sorrow and sadness, we mourn our beloved son: Prince Al-Waleed bin Khaled bin Talal bin Abdulaziz Al Saud, may Allah have mercy on him, who passed away today.' 4 Prince Al-Waleed bin Khalid Al-Saud died at the age of 36. 4 The prince had been in a coma since 2005. Prince Al-Waleed was studying at a military college in London when he was involved in the devastating car crash. After the accident, he was hospitalized at King Abdulaziz Medical City in Saudi Arabia's capital Riyadh, where he remained in a coma ever since. Prince Al-Waleed's father never gave up hope that his son would one day make a full recovery. He remained involved in the prince's care and firmly rejected calls to withdraw life support. The hashtag 'Sleeping Prince' has widely trended on social media following the announcement, with thousands offering their condolences. 'May Prince Al-Waleed bin Khaled, Rest In Peace. Deepest sympathies to his loved ones,' one wrote. 4 The prince suffered a brain haemorrhage and internal bleeding after a car crash when he was 15 years old. 4 Prince Al-Waleed's father always hoped his son would make a full recovery. 'Your time on earth was a blessing to your family and the world in general,' another said. 'May his gentle soul rest in perfect peace,' a third said. Funeral prayers for the prince will be held today at Imam Turki bin Abdullah Mosque in Riyadh.

Teen receives devastating medical diagnoses after doctors dismiss symptoms as ‘anxiety'
At just 19 years old, Sydney's teen Marissa De Santis spends most of her days in and out of the hospital, fainting up to five times a day, frequently seizing and battling chronic pain so intense it's left her bedridden for weeks. But despite her debilitating symptoms, doctors still dismiss her, telling her she 'looks fine' and sending her home. Marissa has Functional Neurological Disorder (FND), a complex and poorly understood condition that disrupts how the brain communicates with the body. FND affects movement, sensation, and even organ function — yet many medical professionals know little about it, and there's no cure. 'I just want to be independent,' Marissa told 'People have no idea what it is. They look at me and think I look fine.' Marissa's symptoms started in high school. She struggled to concentrate, felt constantly sick, and was often sent home vomiting or in pain. In 2022, she managed to graduate, but months later her health took a steep dive. Marissa has Functional Neurological Disorder (FND), a complex and poorly understood condition that disrupts how the brain communicates with the body. Gofundme She developed Postural Orthostatic Tachycardia Syndrome (POTS) that left her fainting every time she stood, sometimes collapsing on the stairs or in the shower. She's had seizures that left her shaking violently on the floor, with her two most recent ones on Monday. For five weeks earlier this year she was completely bedridden, unable to stand without passing out. She's since been admitted to hospital for a week at a time — but doctors usually just check her vitals, give her some pain medication and send her home. 'No one really knows what to do,' she said. 'I've had so many tests, they all come back fine.' And that's the kicker; People with FND do appear 'fine' on paper, but inside, their body is fighting for its life. After seeing doctor after doctor and being told it was all in her head or it was 'just anxiety', Marissa began to lose hope. 'My body was shutting down, and I was overwhelmed and exhausted beyond words. 'Then one afternoon, everything changed — my body started shaking violently. I lost control. I had a full-body seizure. My eyes locked shut. I couldn't speak, move, or cry for help. 'That was the moment I knew — this wasn't just anxiety. It was real.' Marissa's younger sister Helena, now 17, was diagnosed with FND at just 14. Helena also collapses, suffers seizures and lives with chronic pain, though Marissa's condition is more severe. Their mother Sylvia said that although it hasn't made it any easier, she was able to recognize Marissa's symptoms earlier. 'It's just heartbreaking,' said Sylvia. 'I want them to be better. There's no help, there's no answers, it's so frustrating.' 'Marissa should be worrying about who she's going to party with, not whether she can stand in the shower.' 'I just research and push doctors to listen. But I can no longer work or provide,' she said tearfully. Sylvia has had to quit working for their family's dog grooming business to take on the role of full-time carer in her home. 'We may need to look at selling our house. It's a constant battle,' she says tearfully. The family spends tens of thousands of dollars every year on weekly psychologists, fortnightly psychiatrists, cardiologists, neurologists, pain specialists, rehabilitation programs and even hypnotherapy. Marissa is also taking over 10 medications to help manage her condition, including for her heart and seizures. Marissa De Santis and service dog, Moose. Gofundme Earlier this year, Marissa was also diagnosed with autism level 2. Her care team believes autism contributed to her nervous system 'overloading,' triggering the FND. Marissa's autism diagnosis has meant the family now has access to minimal NDIS support but FND and POTS are yet to be recognize on their own. Recently, Marissa's family surprised her with a visit from a service dog named Moose. 'When Moose visited Marissa, her heart rate dropped drastically,' said her mum. Moose carries a hefty fee of $30,000 but will allow Marissa to regain a sense of independence and a better quality of life. He will be able to notify her of oncoming seizures or fainting spells. He will also be able to press a doorbell that sends an alert in case of emergencies and assist Marissa in learning how to walk again using his walking frame. Marissa has bravely spoken out about her condition for the first time, creating a GoFundMe to raise money to have access to Moose, who she says would be a lifeline. 'With a Moose by my side, I could reclaim parts of my life that I've lost — and maybe even feel safe enough to go outside on my own again,' she said. Marissa says all she wants is a bit of awareness about what she's going through. 'People have no idea what it is, but disabilities can be invisible. People often make a quick judgement but you can't tell what's going on inside someone's head.'

If you drink your coffee at this time, you're doing it wrong
Welcome to Ask Doctor Zac, a weekly column from This week, Dr. Zac Turner deep dives into the best – and worst – time to drink that cup of coffee. QUESTION: Dear Dr. Zac, I love coffee, but I also know it can be a great stimulant to help me get through the day. Is there a science behind what time of the day I can have a coffee when it is most beneficial to give me that extra bit of zing in my step, whether it's getting my work done, going to the gym, or even staying awake at night during a movie? I'm keen for any information you can give me. – Joel, 33, Gawler SA Advertisement ANSWER: Hi Joel, Let me start with the hard truth: most people are drinking coffee at the absolute worst time of the day — and it's sabotaging their energy without them even realizing it. 5 A doctor has warned that most Australians are drinking coffee in the wrong way, and it can have dire consequences. New Africa – Yes, I'm talking about that beloved first thing in the morning coffee. The sacred moment when bleary-eyed Australians stumble toward the kitchen like zombies hunting for espresso. But here's the kicker — that cup might actually be setting you up for a massive crash before morning tea. You're drinking coffee too early — and here's why that's a problem Advertisement You see, your body already has its own built-in coffee machine. It's called cortisol. Every morning, about 30–60 minutes before you wake up, your body starts pumping this natural energy hormone. By the time you've had a stretch and checked your phone, cortisol is peaking, meaning you're already wired (or should be). 5 Dr. Turner said that drinking coffee in the morning will sabotage your energy. Getty Images/iStockphoto Now here's where it gets messy: if you down a coffee during that cortisol surge, you're stacking caffeine on top of your body's natural stimulation. That might sound like a great energy hack, but in reality, it can cause jitteriness, anxiety, and, over time, tolerance. That means your daily double shot is doing less and less for your focus and mood. And let's not even talk about the stomach dramas. Advertisement Oh, and that midmorning slump? The one that hits like a bus around 10 a.m.? Blame early caffeine. When you drink coffee right after waking, there's hardly any fatigue for it to block — so when the caffeine wears off, you fall off a chemical cliff. 5 When you drink coffee right after waking, there's hardly any fatigue for it to block — so when the caffeine wears off, you fall off a chemical cliff. Getty Images/iStockphoto The smarter time to sip The golden window for your first coffee is 60 to 90 minutes after waking. Why? Advertisement • Cortisol has peaked and is gently declining, so caffeine won't tip you over the edge. • Adenosine (your body's 'tiredness' signal) has started to build, and caffeine can finally do its real job of blocking it. Drink it then, and you'll feel more alert, avoid the crash, and ride the caffeine wave like a pro. But what if you hit the gym early? 5 The golden window for your first coffee is 60 to 90 minutes after waking Adobe Stock Now, Joel — if you're one of those rare people who enjoy exercising at sunrise (can't relate, personally), you can bend the rules. Caffeine before training can boost endurance, motivation, and power output, as long as you slept well. Just go easy on the dose. Even half a cup can do the trick. No sleep? Be warned — early caffeine can block leftover adenosine too soon, setting you up for a post-gym nosedive. Sometimes, training without caffeine helps reset your body's sensitivity and prevents dependency. One more thing … stop sipping after 2 p.m. Advertisement Caffeine has a half-life of about six hours, so that innocent 3 p.m. flat white could still be messing with your sleep at 9 p.m. If you're wondering why you're wired at bedtime after the afternoon cup, now you know. Final word 5 If you drink coffee 60-90 minutes after waking up, you'll feel more alert, avoid the crash, and ride the caffeine wave like a pro. Getty Images Your coffee isn't the enemy — your timing is. Get it wrong and you'll feel anxious, dependent, and crashy. Get it right, and your cup becomes a performance-enhancing, focus-boosting, feel-good tool. Advertisement So next time you roll out of bed and reach for the espresso machine, pause. Let your body wake up naturally first. Then let that coffee work with your biology, not against it. Trust me, Joel — your 10 a.m. self will thank you. Yours in better buzzes, Dr. Zac.
