Coffee Health Smelling coffee relieves fatigue more than drinking coffee

Researchers believe that the aroma of roasted coffee beans can calm serious nerves-and just a little fragrance can alleviate the effects of a long night's sleep on the brain.

After sampling the brains of mice, they found that the smell of coffee enhanced the activity of critical genes that promote cell survival and reduce anxiety.

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

Researchers believe that the aroma of roasted coffee beans can calm serious nerves-and just a little fragrance can alleviate the effects of a long night's sleep on the brain.

But a new study suggests that this function may be caused by the aroma of coffee rather than coffee itself.

When you get up in the morning, a novel cup of ground coffee can be refreshing.

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 nights sleep on the brain.

Aroma: Just smelling coffee can help cure tiredness better than drinking a cup

Smell: just smelling coffee can help relieve fatigue more than drinking a cup of coffee.

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

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.

Sooner or later, they say, people's fatigue can be alleviated by extracting chemicals from coffee and releasing them into the air.

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.

Scientists in Tsukuba, Japan, put 16 mice in cages with an inch of water to keep them awake for 24 hours. Then, put half of the mice in the fragrance of roasted coffee.

After sampling the brains of mice, they found that the smell of coffee enhanced the activity of critical genes that promote cell survival and reduce anxiety.

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.

Professor Yoshio, who led the Tsukuba research team in Japan, said that when people drink coffee in order to stay up late, the taste of the coffee alone reduces the stress caused by not sleeping.

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.

Smelling coffee beans is better than drinking coffee, he added. But will the smell of other foods have a similar effect?
