The impact of technology on our physical and mental health is still the subject of scientific studies.
Shimi Kang is a Canadian psychiatrist who specialises in child and adolescent mental health, focusing on addiction.
She told the BBC: "Technology is increasingly being linked to anxiety, depression, body image disturbance, and internet addiction disorder has now become a medical diagnosis."
But just as there are healthy foods, super foods and junk foods, there are several types of technology – and if we want a healthy relationship with them, we need to understand how they impact our brains.
但就像健康食品，超级食品和垃圾食品一样，技术种类也多种多样 - 如果我们想要与它们建立健康的关系，我们需要了解它们是如何影响我们的大脑的。
Kang says our brain "metabolises" technology by generally releasing six different types of neurochemicals into our bodies:
Serotonin - Released when we are creative, connected, and contributing.
血清素 - 当我们富有创造力，交际力和富于贡献时就会产生。
Endorphins - The "painkiller" of the body. Released when we experience mindfulness, meditation, gratitude, and cardiovascular exercise.
内啡肽 - 身体的“止痛药”。 当我们体验正念，冥想，感恩和心血管锻炼时就会释放。
Oxytocin - Released when we have exchanges in a meaningful connection. It is generally healthy but online predators can tap into its effects to abuse their victim’s trust.
催产素 - 当我们进行有意义的交谈时释放。 它通常是健康的，但在线掠夺者可能会利用其影响滥用受害者的信任。
Dopamine - A pleasure neurochemical linked with instant reward but also addiction. Technology is increasingly being designed to specifically trigger the release of dopamine.
多巴胺 - 一种与即时奖励相关的快乐神经化学物质，也与成瘾有关。 越来越多的技术在设计的时候有意地触发使用者的多巴胺释放。
Adrenaline - Best known for regulating our responses in fight-or-flight situations, but also released by likes and pokes on social media.
肾上腺素 - 以在“战斗或逃跑”情况下调节我们的反应而闻名，但如果你在社交媒体上被点赞或“戳了一下”，这个激素也会释放。
Cortisol - The hallmark of stressed-out, sleep-deprived, too-busy and distracted individuals.
皮质醇 - 压力过大，睡眠不足，过于忙碌和分心的人的标志。
"Healthy technology is anything that would give us that metabolism of brain-boosting serotonin, endorphin and/or oxytocin," Kang says.
Some examples are meditation apps, creative apps, as well as connection apps that allow us to bond with other people.
But add a good dose of habit-forming dopamine and you are entering a dangerous territory that can lead to addiction.
