Millions of teenagers are in danger of putting their health at risk by getting hooked on e-cigarettes, experts warn. Leading health researchers say they are “very concerned” by the growing number of youngsters trying the devices.

E?cigarettes have been marketed as a healthier alternative to smoking conventional cigarettes. But previous research shows e?cigarettes generate poisonous chemicals similar to those found in tobacco and may harm the lungs and immune system.

Worryingly, researchers at Liverpool University discovered 16% of teenagers who have used e?cigarettes had never previously smoked. The experts also found e?cigarettes were “strongly related” to drinking among teenagers. Study author Prof. Mark Bellis said, “Our research suggests that we should be very concerned about teenagers accessing e?cigarettes. While debate on e?cigarettes has focused largely on whether or not they act as a gateway to tobacco cigarette use, e?cigarettes themselves contain a highly addictive drug that may have more serious and longer lasting impacts on children because their brains are still developing.”

Researchers surveyed 16,000 students aged 14 to 17 in the North West of England and asked them about their alcohol and tobacco use. They found that one in five answered yes to the question: “Have you ever bought or tried electronic cigarettes?” More males than females said they had.

Of the teenagers that had accessed e?cigarettes, 16% had never smoked, 23% had tried smoking, 12% only smoked when drinking, and 14% were ex?smokers. The research also found teenagers who drank alcohol were significantly more likely to have accessed e?cigarettes than non?drinkers.

Among those who had never smoked, it was found that those who regularly have excessive(过多的)drinking were four times more likely to access e?cigarettes than those who never drink. In all of those that drink, regardless of smoking status, e?cigarette access was associated with excessive drinking and involvement with violence after drinking. The researchers said their findings suggest that teenagers who use e?cigarettes are most susceptible to other forms of substance use and risk?taking behaviors.

A long flight can affect one's biological block, sometimes for days. Air travelers can get very tired and develop unpleasant feelings when they fly great distances across time zones. The natural order of things can become unbalanced on long, overseas trips from east to west or from west to east. This is what we call jet lag. 1.

● Try changing your meal and sleep times before you go

Several days before you travel, start moving your bedtime and hours for meals closer to the times you plan to eat and sleep on your trip.
