A cup of freshly ground coffee is what it takes to get some people moving in the morning.

But, according to a study, it may be the aroma rather than the coffee itself that does the trick.

Researchers believe that the aroma of roasted coffee beans can soothe frayed nerves - and that just the whiff could be enough to reverse the effects of a poor night's sleep on the brain.

They said that chemicals extracted from coffee and pumped into the air may one day be used as a way of reviving tired people.

Scientists in Tsukuba, Japan, kept 16 laboratory rats awake for 24 hours, by keeping them in a cage filled with an inch of water, then exposed half of them to the smell of roasted coffee.

After taking samples of the rats' brains, they found that the smell of coffee boosted the activity of key genes that promote cell survival in the body and reduce anxiety, New Scientist magazine reports today.

Professor Yoshinori Masuo, who led the study in Tsukuba, Japan, said that when people drink coffee to stay up all night, just the smell of the coffee could alleviate some of the stress caused by sleeplessness.

He added: 'Is it better for us to smell coffee bean aroma than to drink coffee, or would any other food-related odour produce similar effects? Further studies are needed.'

yup.. coffee ( nt those kopitiam kind) are generally low in caffine level.. most ppl will think the strongest is actually an espresso double however that is not the case. the most caffinated item at a cafe will be the cafe brew aka brew of the day. depending on what is that brew, it will have different taste, aroma, body and acidity. so one actually gets more awake at the whiff of the coffee smell if its really nice smelling, chances are u enjoy it more.. nt like mac de... ewww

how do i get confidence & the bravery i need and to be able to say what i wanna say and not hide all things to myself... i wonder

i myself drink at least 10 glasses = 2.5 liters of plain water every single day.
if morning take 1 glass of coffee, i need to drink 3.5 liters of plain water. to replenish back the 1 liter loss.
best water % for men is 60% to 65%
best water % for women is 55% to 60%
i myself is at abt 63%

Triglav

And where is your source?

Dun come here sprout rubbish.

Coffee is just a mild duretic that may have some effect on dehydration if drank in excessive amount but to say 1 glass of coffee take away 4 glasses of water is entirely rubbish......

Wonder how can people even believe this, you no common sense ah? There are so many people who drink like 3-4 or even way more cups per day.By your " logic" they will already be dead since they will be losing so much water that they will already be dried corpse......

Triglav

yeah right, dun listen to that Andy sprout rubbish, he know almost nothing about health issues.

KENJ

nope and that has nothing to do with what you claims that 1 glass of water take away 4 glass of water.

Not able to provide proof of the rubbish you are sprouting and trying to divert away the attention?

andylee

if u choose not to believe, i also cant help it.
my mum drink 1 glass of coffee daily last time & 10 glasses of water
her water % always not in the good range.

now she only take coffee once a week. and she still drink 10 glasses of water
but her body water % improve.

i can let u noe ur body water % within 5 mins.
