The cure for sleeping problems can often be found in your daily routine. Your day-to-day lifestyle choices greatly influence the quality of your nightly rest. The following tips will help you to get a better sleep.
Set a regular bedtime. Choose a time when you normally feel tired to go to bed so that you don’t toss and turn for hours before falling asleep. Try not to break this routine at the weekend, when you may want to stay up late. If you want to change your bedtime, help your body adjust (适应) by making the change gradually.
If you can’t avoid the noise of barking dogs, loud neighbors, city traffic, or other people in your household, try masking (掩盖) it with a fan, recordings of smoothing (舒缓的) sounds, or white noise. You can buy a special sound machine or produce your own white noise by setting your radio between stations..
Keep your room cool.Most people sleep best in a slightly cool room (around 65℉or 18℃). A bedroom that is too hot or cold is not good for your sleep.
You should have enough room to sleep comfortably. If you often wake up with a sore back or an aching neck, you may need to buy a new mattress (床垫) or a different pillow.

A.Try to keep the noise down.
B.Earplugs (耳塞) may also help.
C.Make sure your bed is comfortable.
D.Go to bed at the same time every night.

E. Spend more time outside in the daytime.
F. The temperature of your bedroom also affects your sleep.
G. If you are getting enough sleep, you should wake up naturally without an alarm.

Hospital emergency rooms treat injured fingers all the time.Without treatment, a bad cut can lead to permanent damage.But how should a person know when a bleeding cut is serious enough to require medical attention?
Here are some tips from Dr. Martin Brown, chairman of the department of emergency at Inova Alexandria Hospital in Virginia.
1. Laceration (裂口)
The medical term for a cut or tear in the skin is a laceration.A long cut on a finger can likely be treated without a visit to a doctor if the wound is not very deep. However, if you have a short but deep laceration, you will need professional attention.
2. Fingertips cut off
Some injuries, like a fingertip that gets cut off, might even need surgery to repair.More often, cutting down the bone is what is done because reattaching a fingertip is often not successful.
3. Bleeding
Small cuts usually produce what is known as venous (静脉的) bleeding. This means the blood flows steadily from the injury.The bleeding will often stop when pressure is put on the wound. In most cases holding direct pressure with a clean cloth for four to rive minutes would do.But if a cut appears to be pumping blood out with some force, this may be a sign of arterial (动脉的)bleeding.
Finally, always keep this in mind: even a cut that does not require medical attention must be kept clean to prevent infection. Small cuts should be cleaned gently with clean water.Then cover it with a clean, dry bandage.

A.How a wound bleeds can be a sign of how serious it is.
B.That requires a specialist to either cut down the bone or reattach the fingertip
C.This kind of injury should be treated by a medical professional as soon as possible.
D.The first signs of this disease include difficulty in opening the mouth.

E.Use a washcloth to clean the area if the wound is dirty.
F.With a cut finger, holding the hand above the heart can reduce the loss of blood.
G.The length is usually not as important as the depth.
