Take Time to ReflectFive Simple Ways to Increase Your Intelligence Your brain needs exercise just like a muscle. If you use it often and in the right ways, you will become a more skilled thinker and increase your ability to focus. Here are 5 simple ways anyone can squeeze a bit more productivity out of the old gray matter. 1. __________-This is a hard sell. People love vegetating in front of the television, myself included more often than I’d like. The problem is watching television doesn’t use your mental capacity OR allow it to recharge. It’s like having the energy sapped out of a muscle without the health benefits of exercise. When you feel like relaxing, try reading a book instead. If you’re too tired, listen to some music. When you’re with your friends or family, leave the tube off and have a conversation. All of these things use your mind more than television and allow you to relax. Exercise- I used to think that I'd learn more by not exercising and using the time to read a book instead. But I realized that time spent exercising always leads to greater learning because it improves productivity during the time afterwards. Using your body clears your head and creates a wave of energy. Afterwards, you feel invigorated（精力充沛）and can concentrate more easily. 2. __________-Many people like to read popular suspense fiction, but generally these books aren't mentally stimulating. If you want to improve your thinking and writing ability you should read books that make you focus. Reading a classic novel can change your view of the world and will make you think in more precise, elegant English. Don’t be afraid to look up a word if you don’t know it, and don’t be afraid of dense passages. Take your time, re-read when necessary, and you’ll soon grow accustomed to the author’s style. 3. __________-Nothing makes it harder to concentrate than sleep deprivation. You'll be most rejuvenated if you go to bed early and don’t sleep more than 8 hours. If you stay up late and compensate by sleeping late, you’ll wake up lethargic（无精打采）and have trouble focusing. In my experience the early morning hours are the most tranquil and productive. Waking up early gives you more productive hours and maximizes your mental acuity（敏锐）all day. If you have the opportunity, take 10-20 minute naps when you are hit with a wave of drowsiness. Anything longer will make you lethargic, but a short nap will refresh you. 4. __________-Often our lives get so hectic that we become overwhelmed without even realizing it. It becomes difficult to concentrate because nagging thoughts keep interrupting. Spending some time alone in reflection gives you a chance to organize your thoughts and prioritize your responsibilities. Afterwards, you’ll have a better understanding of what's important and what isn’t. The unimportant stuff won’t bother you anymore and your mind will feel less encumbered. Conclusion-I hope you aren’t disappointed that none of the techniques I've proposed are revolutionary. But simple, unexciting answers are often the most valid. The challenge is having the will to adhere to them. If you succeed in following these 5 tips, you’ll be rewarded with increased mental acuity and retention of knowledge.
Do you sleep well? Some people get off to sleep as soon as their head hits the pillow, but many others are not so lucky. In fact, the lack of quality sleep has become a public health issue around the world. According to me World Association of Sleep Medicine, 45 percent of the world's population suffer from sleep problems. One in eight people don't sleep well and are easily woken. 7.6 percent sleep less than 3 hours each night. Some even cannot fall asleep for several days in a row.
As a basic bodily and mental need, sleep is essential for our survival, it helps us to fight diseases, strengthen our memory, perform better in work and school and improve our quality of life. Lack of sleep is known to have a significant negative influence on health, both in the short and long term. Poor sleep has been associated with obesity, diabetes, weakened immune systems and even some cancers, as well as depression and anxiety.
The World Sleep Day, held on the third Friday of March, is an annual celebration of sleep to lighten the burden of sleep problems through better prevention and management of sleep disorders.
To achieve this goal, we must figure out what causes sleepiness and sleeplessness.
Unhealthy lifestyle may be the first to blame. More and more people use cell phones and computers in bed, with many staying up until midnight. Modern technology does make our life convenient, but abuse of it ruins our health. Environmental conditions, such as temperature, noise, light, bed comfort also play an important Pole in one's ability to get proper sleep. Besides, improper evening diet, like a full or an empty stomach, coffee and alcohol all contribute to sleep problems. Of course, when it comes to causing poor sleep, stress from finances, family or work should never be ignored．
However, those who suffer from sleep disorders don't necessarily have to continue to do so -most sleep problems can be managed．
