“An apple a day keeps the doctor away.” Similarly, if we drink a little more water every day, we may find that we need to go to the doctor a lot less often. A healthy diet is made up of water and a great many different kinds of foods. We know that healthy foods like fruits, vegetables and fish, are important as they provide us with energy and fiber, without giving us too much fat and sugar. But why is water important?
The human body needs water to survive. Water is important as it carries poisons and waste out of our bodies. However, doctors advise us to drink plenty of water, much more than the small amount we need to stay alive.
Some doctors believe that water is important for our health in all kinds of ways. They believe that a great many illnesses and health problems start as a result of dehydration(脱水)—a lack of water in the body. Most people are dehydrated at least some of time, although they probably don't know it. It is surprising to learn that if we feel thirsty, we are already in the first stage of dehydration. In fact, we are advised to drink water before we feel thirsty.
These doctors think that health problems such as headaches, high blood pressure and asthma(哮喘) could be helped if people drink more water. They also believe that drinking more water can help people who are overweight. Water contains no calories so it will not make us put on weight. If we drink water, we will probably drink less sugary soft drinks such as Coca-cola. Doctors also believe that drinking more water may stop people from overeating. They say that many people think that they are hungry when they are, in fact, thirsty. Doctors suggest, therefore, that we eat less food and drink more water. There are still many health problems that cannot be solved by drinking water, so we should not stop going to seeing the doctor completely. However, if we make a decision to drink water every day, we may find that we need to go to the doctor a lot less often.
Nowadays airfare isn't getting any cheaper with fuel costs rising every day. Luckily, there are plenty of ways to find the most affordable fares and also avoid paying as many extra charges as possible when you plan ahead.
♦ Getting the best fare Fly during the least popular times. Tuesday, Wednesday and Saturday are the slowest days to fly, which means cheaper deals than the rest of the week. You can also find reduced rates on early morning flights, since many people don't like to get up before the sun to get to the airport. Earlier boarding times can also considerably cut down your chances of getting delayed because of other delayed flights or mechanical issues. Choose your seat later. Some airlines charge you to pick your seat when you book online, adding even more to the bottom line of your ticket cost. If you show up early on your travel day, you can still have a chance to get suitable seats that others are not willing to pay extra for ahead of time. Fly on holidays. You already know that summer is the most expensive time to fly, but the days surrounding holidays can also be crazy. Save big if you're willing to travel on major holidays, such as Thanksgiving and Christmas. Don't wait until the last-minute to book. Book too early or too late and you could end up paying more than you need to. The best time to book is between three months and six weeks from when you want to travel. ※ ※ ※ ※ ※ ※ ※ ※ ♦Avoiding extra fees Avoid the upgrade(升级). It's not necessary. Sometimes upgrades are free, but mostly you will be charged for seeking a last-minute bump to first class, and the cost can be very high. Fly carry-on only. Baggage fees vary wildly, but almost all airlines charge them and charge big. It's easy to reduce the amount of stuff if you pack less clothes and only travel-sized toiletries. Planning to do a bit of laundry on your trip will also do. Pack your own snacks. Unless you're flying internationally, it's rare your flight comes with a free meal. So put some of your own snacks — homemade muffins, fruit and granola bars all make fantastic travel foods — into your bag and eat a lot better, and cheaper, than other passengers. |
