Risk of ADHD Seven Times Higher in Preschoolers Who Spend Over 2 Hours on Smartphones

Preschoolers who spend more than two hours per day on smartphones and tablets are seven times more likely to develop the symptoms of ADHD, according to new research.

The study of nearly 3,500 Canadian children aged 3~5 found that those who had over two hours of screen time per day were also five times more likely to display inattention, acting out, and hyperactivity compared with those who spent less than 30 minutes on a screen per day.

The researchers also looked for things that appeared to reduce the negative effects of screen time on their behavior. While good sleep had little impact, participation in organized sports was the most outstanding factor.

想一想:

1. 本文中的研究發現,3~5歲的孩童每日使用2小時以上的3C電子產品,比每日使用30分鐘以下,容易產生哪些問題?

2. 根據文章,該研究還發現什麼,可以有效改善3C導致的負面影響?

3. 試分享你的獨門祕技,如何減少孩童使用3C?

--------------------------------------------------------------------------

解答:

1. inattention, acting out, and hyperactivity (注意力缺乏、鬧脾氣、過動)

2. participation in organized sports(參與有規則的運動。例如:籃球、足球等)

iPhone Radiation: Ways to Protect Yourself & Reduce Exposure

According to basic principles of physics, as distance from a source of EMF radiation increases, intensity of exposure decreases dramatically; in other words, simply putting a few inches between you and your device will considerably reduce the amount of iPhone radiation absorbed by your body. When you make a call, keep in mind that iPhone radiation is highest when first making a connection, so avoid putting the phone to your ear until the call is connected.

Airplane mode isn’t just for flying. This feature is a simple way to immediately disable all wireless transmissions, thus reducing iPhone radiation. When airplane mode is enabled, your iPhone is no longer connected to WiFi, Bluetooth, or cellular data, meaning it is no longer constantly sending out RF signals (radiation) to remain connected.

Know when iPhone radiation is at its worst. There are conditions in which your iPhone must work harder to maintain a good connection to a source. Consequently, it emits more EMF radiation and poses a greater health risk. This is a common occurrence when you’re in an area or building with poor reception and also when you are driving.

想一想:

1. 根據文章第一段,什麼因素能減少身體吸收電磁波輻射?

2. 文章中提到許多關於保護自己、減少曝露在手機輻射下的建議,請試舉兩個例子?

3. 在閱讀過本文後,你是否有新的收穫?

--------------------------------------------------------------------------

解答:

1. distance (距離)

2. (1)在電話接通前,避免將耳朵靠近手機。(2)經常開啟飛航模式,中斷無線傳輸。(3)避免在收訊不良處或開車中使用手機進行通話。
