The weather is getting hotter. You are thirsty playing basketball or riding home from school. A cold drink may be just the thing. But be careful what you are drinking. Something that looks cool may not be good for your health. There are plenty of “energy drinks” on the market. Most of them have beautiful colors and cool names. The lists on them tell you they are helpful to your health. Sounds great!

But after a careful check you may find that most energy drinks have lots of caffeine(咖啡碱)in them. These drinks are especially aimed at young people, students, busy people and sports players. Makers sometimes say their drinks make you better at sports and can keep you awake. But be careful not to drink too much. Caffeine makes your heart beat fast. Because of this, the International Olympic Committee(IOC) has limited(限制) its use. Caffeine in most energy drinks is at least as strong as that in a cup of coffee or tea. Possible health dangers have something to do with energy drinks. Just one box of energy drink can make you nervous, have difficulty sleeping and can even cause heart problems. Scientists say that teenagers should be discouraged from taking drinks with a lot of caffeine in them.

Blood donation, also called blood banking, is a wonderful thing to do. It is an easy and direct way to contribute to social work and help the community. It helps to save lives and helps those who are in need of blood due to bad condition or the heavy loss of blood during operations or in accidents.
You are able to give or donate blood every three or four month, and it is a great way to make  a huge difference to someone’s life and you can always be proud of it after making valuable contributions to society. Blood donation is not a big problem, but you need to keep a few points in mind.
Before donating blood, make sure that the ferrum (铁) level in your body is high enough and for that you should take a healthy diet. Do not go for blood donation on an empty stomach. You should follow the correct process so that everything goes well. After having a balanced diet you will feel strong and comfortable to donate blood. Afterwards, you will not feel faint or weak.
For required hemoglobin (血红蛋白) in your body, drink lots of juice and other drinks. Fruit juice, such as apple juice is very good for increasing the blood level in your body.
For a good blood flow in your body, drink at least 6-7 glasses of water every day. Completely avoid a day before and after giving blood, taking alcohol (酒). Do not smoke half an hour before giving blood.
When you are going for blood donation, be relaxed, which helps keep the right blood pressure. During the blood donation activity, take a deep breath and try to calm yourself. Don’t join in some other activities.
When you donate blood, you are making the effort to save someone’s life. Blood donation is a very simple and fast process, but you need to take care of yourself after donating blood. Proper care helps to reduce side effects. The following are a few tips that will help you out.
Take a rest for 15 minutes after the donation. It helps you to feel relaxed.
Eat something and drink juice before leaving the blood donation centre. Make sure that you have meals after donating blood. Smoking should be avoided for one hour after the process. Avoid some activities right away, for example, driving.
Finally, be proud of yourself because you have done a great thing in helping to save someone’s life. Blood donation is a very important activity.
