New research shows the effects energy drinks can have on teens -- especially when they're mixed with other things like alcohol.
Researchers say these popular drinks are risky because they contain high amounts of caffeine and other ingredients designed to give the body a jolt.
They found the drinks can lead to harmful effects in teens, including heart issues, anxiety, digestive problems, insomnia and dehydration. The problems become worse when the drinks are mixed with alcohol.
The beverage industry claims energy drinks are no more harmful than other drinks that contain caffeine, like coffee.
New research shows too much time watching TV can reduce men's fertility.
A study from Harvard University shows men in western countries may have lower-quality sperm concentration because they watch more TV--in other words, they spend more time being physically inactive.
Men in the study who said they exercise 15 or more hours a-week had higher sperm concentration.
Men who said they watched more than 20 hours of TV a-week had only half the number of sperm cells as men who watched no TV.
