【推荐1】If you often feel tired, and the doctor can't find anything wrong with you, you may be in a state（状态）of subhealth. Subhealth is a state between health and illness. Most of the subhealthy people are middle-aged ones who are usually stressed out（筋疲力尽） because of work and family. And some of them are students who are having exams.

If you are subhealthy, it's not difficult for you to recover. You should have good living habits. For example, you should get up early and go to bed early. And you should exercise. Exercising can keep you healthy. As for meals, it's better to eat less salt and sugar. Vegetables, fruit and fish are important to your body. You should eat more of them. It is not good to eat too much at one meal, because it may cause unhealthy changes in the digestive tract（消化道）. And at last, a balanced diet is very helpful in keeping healthy.

【推荐2】This is not a diet. It's a simple way to lose weight. And you don't even have to give up the food you love or join a gym. You just follow some habits that thin people have. Keep them, and you'll become thin.

1. Wake-up

When you wake up in the morning, sit up slowly without using your hands. With legs straight out, bend（弯曲）forward until you feel sore in your back. It will burn about 10calories（热量单位：卡路里）.

2. Start with soup

When you have a meal, order a clear soup, and have it before having the main food. In this way, you'll feel fuller, so you'll eat less when the main food comes.

3. An apple (or more) a day

Apples are full of fiber（纤维）and water, so your stomach will want less food. The study shows that people who eat at least three apples a day lose weight.

4. Stand up and walk around

Every time you use the mobile phone, stand up and walk around. Heavy people sit on average（平均）two and a half hours more each day than thin people.

This skill is very important as standing up and walking around will burn 50or more calories.

Use these skills, and you will have a big weight lose.

【推荐3】Healthy Living Habits for Teenagers

Today we can do everything with apps: pay bills, order food and shop for anything. Mobile technology means we can hold the world in our hands. However, when it comes to technology and health care, chances and challenges come together.

Let’s start with the ways to get health care. Telemedicine (远程医疗) can allow a patient to use technology to see the doctor online and get a diagnosis and instructions without leaving home.

There are many online patient websites, which have different kinds of interactions (互动) about our health needs. Setting a date with doctors and reading results have been achieved by technology already.

A whole new age of medical care seems possible to come in the future. But every coin has two sides. What might be on the other side of techno-health care?

First, sharing the details of one’s health requires trust, which takes time to build. This is certainly true in health care, where some of life’s best and worst moments have something to do with doctors. The human touch is also very important for patients and is impossible to be there over the smartphone.

Second, test results can be difficult to understand. When someone without a medical degree sees a result with no explanation on the website, there’s room for all kinds of terrible stories to form in their minds.

So how does medicine get along well with the new technology age? Some talented companies are working on it. There is medical equipment that can be used at home to send necessary signs and heart sounds through telemedicine. It seems possible that some companies will find a way to explain test results.

But what it will not achieve is the touch and the warmth of human interaction. Patients often need someone to listen to and care about their journey story, which will never be realized through a human-less technology. Technology should be a tool, but depending on it totally will probably have unexpected effects.
