How to improve body and mind at home

To most people, holiday is a time to stay at home and have a good rest. Thanks to social media, computer games and online TV series and movies, staying inside is great fun. But too much time on media and digital entertainment could be a heavy burden to both the mind and eyes. Here are five activities you could try to get away from the screen for a while.

1.

If you choose a good book, it can help you enjoy a whole day at home. The ability of your brain to process words could be greatly improved through reading. And your vocabulary could be enlarged as well. Personally, paper copies are suggested. The touch and smell of real paper has no digital replacement.

2.

Everyone can write something, even if it may look very ugly at first. But the point of such practice is not to write beautiful characters. It’s about improving your ability to calm down and focus, as you must breathe deeply to keep your hands from shaking when practicing handwriting.

3.

You can just pick up a brush and draw anything, either nearby or something you imagine. Copying paintings is one nice beginning option. Copies of the Dunhuang Mogao grottoes are a good choice.

4.

Chopin, Mozart, Bach. Any of these great musicians could attract you with their works of art. Even if you prefer pop music, give classical music a chance.

5.

Many Chinese people, especially women, are crazy for yoga. Now it is a good time to practice yoga every day to relax your body. Likewise, you can try tai chi, which can improve both mind and body.

A.Read books, or at least listen to them.

B.Just listen, and let your brain and ears take a break.

C.You don’t have to be professional before picking up a brush.

D.While improving your mind, your body should also be cared for.

E.Drawing is natural pleasure that has a long history and it is still fun.

F.There are online audio lessons to help you learn a musical instrument.
