Drinking two cups of coffee a day could help you sleep years later, a study shows

Scientists have discovered that a life of daily cafes can reduce a part of the brain that controls sleep patterns

For many of us, a cup of strong coffee is just what moves us to action in the morning.

And with the British drinking 95 million cups a day, it has never been so popular.

But now scientists have discovered that a life of daily cafes can reduce a part of the brain that controls sleep patterns.

They believe that the findings may explain in part why some older people struggle to leave the world.

Brain scans carried out by researchers at Seoul University in South Korea found that moderate-to-strong consumers-those who drank two cups a day for 30 years or more-had smaller pineal glands than those who rarely drank. coffee.

The pineal gland is a pea-sized organ in the middle of the brain that releases a hormone called melatonin when it's time for the body to rest and sleep.

The smaller the gland, the less melatonin it produces.

Although caffeine is well known as a short-term stimulant, it is believed that this is one of the first studies to suggest that it could have long-term effects on the brain.

Researchers tracked 162 healthy elderly men and women and questioned them about how much coffee they drank and how much they slept.

They then performed magnetic resonance imaging scans to measure the volume of the pineal gland.

They discovered that coffee lovers had pineal glands 20% smaller than those who did not drink and had more trouble sleeping.

They said that years of daily coffee consumption could damage the brain and the quality of sleep later in life.

In their report, published in the journal Sleep, the scientists warned: "Given the large amount of coffee consumption worldwide and the rapid increase in the use of caffeine in children and adolescents in the last 30 years, we should be concerned about the Potential adverse effects of coffee consumption for life. & # 39;

However, Dr. Neil Stanley, an independent sleep expert, said the research did not prove that the caffeine in the coffee was damaging the quality of sleep among the elderly.

He added: "Different cups of coffee may have different levels of caffeine in them, but the study did not take this into account, nor any other source of caffeine they may have consumed over the years."
