tudy. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive（认识的）abilities. “I’m pretty sure there is no effect on short-term memory,” he says.

1. Before going to bed, keep a clear mind. Tell yourself that “I will remember my dreams when I wake up”. This is actually a proven and effective way to recall your dreams.
2. Have a regular bedtime and wake-up time. Make this your routine. Going to bed and waking up at a regular time every day could aid in dream recollection.
3. Avoid alcohol consumption and taking medicine before going to bed. These things may prevent you from remembering your dreams.
4. Keep a pencil and a notebook next to your bed so that they will be within reach as soon as you wake up. Having a small lamp by your bedside is also a good idea, so you wake up in the middle of the night and can record your dreams immediately.
5. Do not get out of bed immediately. Upon waking from a dream, lie still in your bed, keeping your eyes closed and moving as little as possible. Let your mind wander among the images of what you have just dreamed.
6. Write down as many details in your dreams as you can, no matter how seemingly unimportant they may be. Do not judge the content or worry if they make sense.
7. Sometimes it may help to draw pictures. A picture is worth a thousand words, as the saying goes. Even if you are not an artist, a simple drawing can help to recall details of your dreams.

“Mobile phone killed my man,” screamed one headline last year. Also came claims that an unpublished study had found that mobile phones could cause memory loss. And a British newspaper devoted its front page to a picture supposedly showing how mobile phones could heat the brain.

One of the oddest effects comes from the now famous “memory loss” s
tudy. Alan Preece and his colleagues at the University of Bristol placed a device that imitated the microwave radiation of mobile phones to the left ear of volunteers. The volunteers were good at recalling words and pictures they had been shown on a computer screen. Preece says he still can’t comment on the effects of using a mobile phone for years on end. But he rules out the suggestion that mobile phones have an immediate effect on our cognitive（认识的）abilities. “I’m pretty sure there is no effect on short-term memory,” he says.
Another expert, Tattersall, remarked that his latest findings have removed fears about memory loss. One result, for instance, suggests that nerve cell synapses（神经元突触） exposed to microwaves become more — rather than less — receptive to undergoing changes linked to memory formation.
An even happier outcome would be that microwaves turned out to be good for you. It sounds crazy, but a couple of years ago a
team led by William Adey at the Veterans Affairs Medical Center in California found that mice exposed to microwaves for two hours a day were less likely to develop brain tumours when given a cancer-causing chemical.
“If it doesn’t certainly cause cancer in animals and cells, then it probably isn’t going to cause cancer in humans,” says William. And while there’s still no absolute evidence that mobile phone use does damage your memories or give you cancer, the conclusion is: don’t be afraid.
