In the Northeast and the Middle West, it is very hot at some times and very cold at other times. People in these states have more heart trouble after the weather changes in February or March.

The weather can also influence intelligence. For example, in a scientific report, IQ of a group of students was very high when a very strong wind came, but after the wind, their IQ was 10% below. The wind can help people have more intelligence. Very hot weather, on the other hand, can make it lower. Students in many schools of the United States often get worse on exams in the hot months of the year（July and August）.

① A survey(调查) has shown that lots of people can't sleep well. Sometimes you feel tired when you wake up. You may have a headache and you feel like you could sleep for another three hours. Many things around us cause sleeplessness. Here are a few changes you can make to improve your sleep.

②Go to bed and get up at the same time. You may share the same bedroom with your sister or brother. You both must go to bed regularly(规律地) so that you don't trouble each other.

③Clean up your bedroom. A study from a university in Zhengzhou found that people with clean bedrooms usually sleep better than those with dirty and untidy rooms.

④ Get more house plants. Studies show that house plants help with reducing (减轻)stress. Also, plants such as lavender(薰衣草) and gardenias(栀子花) have smells that may help some people relax and sleep better.

⑤ Make your room dark. When light hits your eyes, it tell you not to fall asleep. In fact, we need darkness especially in the evening. So if you want your body to know that it's time to rest, turn off the lights about an hour before bedtime or wear eye masks. Your phone and your TV should also be thought of. You may also use the dark curtaıns(窗帘) to keep any outside light from going into your bedroom.

⑥Lower your bedroom temperature. The body becomes cooler at night, so lowering the temperature before bedtime can help you relax and fall asleep more quickly. The NationalSleep Foundation in a country says your bedroom should be about 16 ℃ to 19℃ for a good night's sleep.
