Why we shouldn't like coffee, but we do

Why do we like the bitter taste of coffee? Bitterness evolved as a natural warning system to protect the body from harmful substances. By evolutionary logic, we should want to spit it out, according to Science Daily.

But, it turns out, the more sensitive people are to the bitter taste of caffeine, the more coffee they drink, reports a new study from Northwestern Medicine and QIMR Berghofer Medical Research Institute in Australia. The sensitivity is caused by a genetic variant.

Weightlifting is good for your heart and it doesn't take much

Lifting weights for less than an hour a week may reduce your risk for a heart attack or stroke by 40 to 70 percent, according to a new Iowa State University study. Spending more than an hour in the weight room did not yield any additional benefit, the researchers found, according to Science Daily.

"People may think they need to spend a lot of time lifting weights, but just two sets of bench presses that take less than 5 minutes could be effective," said DC (Duck-chul) Lee, associate professor of kinesiology.

Children spending hours a day in front of screens are at risk of 'short-sightedness, obesity and CANCER'

 

 Spending too much time gawping at screens is making children more likely to be short-sighted, become overweight and get cancer, experts say.

 A review of 80 studies on more than 200,000 people has ranked smartphones and tablets alongside sugary drinks as one of the biggest risks for childhood obesity, according to Daily Mail.

 Being overweight can lead to a dozen types of cancer, including breast, colon, kidney, liver, ovarian, pancreas and prostate.

 As well increasing their risk of dying young, too much time on gadgets is damaging youngsters' eyes – the number of short-sighted children has doubled in 50 years.

Chronic exposure to excess noise may increase risk for heart disease, stroke

Exposure to environmental noise appears to increase the risk of heart attacks and strokes by fueling the activity of a brain region involved in stress response. This response in turn promotes blood vessel inflammation, according to Science Daily.

The findings reveal that people with the highest levels of chronic noise exposure  had an increased risk of suffering cardiovascular events such as heart attacks and strokes, regardless of other risk factors known to increase cardiovascular risk.

The results of the study offer much-needed insight into the biological mechanisms of the well-known, but poorly understood, interplay between cardiovascular disease and chronic noise exposure, researchers said.
