Caffeine is the most consumed psychoactive compound in the world. Even if you don’t drink coffee or tea, you probably still regularly consume caffeine since it’s found in everything from soft drinks and cold remedies to decaf coffee and chocolate.
When caffeine is consumed, it’s rapidly absorbed by the body – reaching peak effects within two hours (though it may take up to nine hours to leave your body). It’s also water and fat-soluble, so it gets into all body tissues, which explains why caffeine can affect many different parts of the body.
It’s recommended that adults consume no more than 400mg of caffeine a day (approximately four cups of coffee). More than this may lead to muscle tremors, nausea, headaches, pounding heart and even death (in extreme cases).
But even people who only consume a couple cups of coffee or tea daily may feel it still has adverse effects – such as irritability, difficulty falling asleep and feeling jittery. This is why a growing number of people are deciding to give up caffeine.
If you’re thinking about giving up caffeine and are wondering what benefits it may have, here’s what the research says:
Brain function
Caffeine withdrawal can cause headaches, fatigue and tiredness. This is because the body develops a tolerance to caffeine.
Caffeine binds to a receptor in the brain used by adenosine. The binding of caffeine to these receptors causes the body to delay the onset of fatigue. But over time the brain cells produce more adenosine receptors to enable normal adenosine binding to happen.
So, when you stop consuming caffeine, there are excess adenosine receptors to bind to. This allows fatigue and tiredness to kick in as normal, with the person feeling more tired than before.
Headaches happens as a result of the absence of caffeine. In the head and neck, caffeine causes the blood vessels to narrow, reducing blood flow to the brain. When you stop drinking caffeine, after approximately 24 hours it causes the blood vessels to return to normal, causing an increase in blood flow to the brain and triggering headaches. They may last up to 9 days on average.
And because caffeine binds to adenosine receptors (which also modulate pain) quitting caffeine may temporarily increase your perception and sensitivity to pain because there’s more receptors available.

Caffeine really only affects sleep when consumed in the late afternoon and evenings. This is because caffeine delays the release of melatonin (a hormone which makes us tired) by 40 minutes. Caffeine also reduces the overall time you sleep and shortens the period of deep sleep.
This can increase your tiredness the next day, leading to cycle of using caffeine to wake you up but having trouble sleeping later on as a result. When you stop caffeine, you may find your sleep improves. Some evidence suggests improvements are seen in as little as 12 hours.
Caffeine has also been linked to increased anxiety and panic attacks – and not just in those with a pre-disposition to mental health issues. Reducing or eliminating caffeine may improve your mood. This may partly be because it improves sleep. Sleep deprivation can exacerbate anxiety and other mood disorders.
But the adenosine receptors that caffeine bind to are also involved in the modulation of other neurotransmitters that have a role in stress, happiness and fear.
Cardiovascular health
Reducing or eliminating caffeine might also cure heartburn and indigestion. Caffeine induces acid secretion in the stomach and weakens the oesophageal sphincter, which controls reflux of stomach contents up the oesophagus – triggering heartburn and indigestion.
Quitting caffeine may also lower your blood pressure and reduce your heart rate – although other studies have shown little change.
This is because if someone consumes caffeine daily for many years, their body adapts to the exposure – and it becomes the new norm with its stimulant effects on the nervous system, bowels and heart.
There also appears to be genetic component to caffeine tolerance and metabolism. This could mean some people are more affected by caffeine over others – though more research is needed on this link.












































































































































































Multifaceted connections. Dual aspect windows and roofline windows crack open this large and light-filled dining space to different views of the garden and skyscrape. Glass walls retract to allow a through-breeze to flow freely, bringing with it the sounds and scents of the environment.

Whether or not you have the proverbial green thumb, you can’t deny that a beautiful garden is the ultimate calming oasis. Whether it’s filled with colourful plots of fragrant blooms or neat rows of towering trees, the public gravitates to these spaces across the globe. Luckily, for anyone in need of a sweet-smelling escape, the world is chock-full of architectural gardens that make even the busiest cities feel serene. Some are old and have been firmly planted in their cities of residence for hundreds of years, while others are technological achievements of the 21st century, but all of them are equally beloved.
