   Everybody sleeps，but what people stay up late to catch or wake up early in order not to miss varies by culture.

From data collected，it seems the things that cause us to lose the most sleep，on average，are sporting events，time changes，and holidays.

Around the world，people change sleep patterns thanks to the start or end of daylight-saving time（夏令时间）. Russians，for example，began to wake up about a half-hour later each day after President Vladimir Putin shifted the country permanently to“winter time”starting on October 26.

Russia's other late nights and early mornings generally correspond（相一致）to public holidays. On New Year's Eve，Russians have the world's latest bedtime，hitting the hay at around 3:30 a. m.

Russians also get up an hour later on International Women's Day，the day for treating and celebrating female relatives.

Similarly，Americans' late nights，late mornings，and longest sleep fall on three-day weekends.

Canada got the least sleep of the year the night it beat Sweden in the Olympic hockey（冰球）final.

The World Cup is also chiefly responsible for sleep deprivation. The worst night for sleep in the U. K. was the night of the England-Italy match on June 14. Brits stayed up a half-hour later to watch it，and then they woke up earlier than usual the next morning thanks to summer nights，the phenomenon in which the sun barely sets in northern countries in the summertime. That was nothing，though，compared to Germans，Italians，and the French，who stayed up around an hour and a half later on various days throughout the summer to watch the World Cup.

It should be made clear that not everyone has a tool to record their sleep patterns；in some of these nations，it's likely that only the richest people do. And people who elect to track their sleep may try to get more sleep than the average person. Even if that's the case，the above findings are still striking. If the most health-conscious among us have such deep swings（明显改变）in our sleep levels throughout the year，how much sleep are the rest of us losing？

   Some people don't wish to waste even a second at work. Looking at a computer screen for a long time can cause stress on one's eyes. Sitting and looking at a television screen for hours can also make the eyes tired.

Bookworms love reading and they will make sure they read much more than their bodies can deal with. The strong wish to finish a book may result in fast reading，without taking breaks, which can lead to tired eyes. Reading for a long time in weak light can also cause tired eyes.

More salt-based junk food like burgers，pizzas, etc. and less water also play a role in causing tired eyes. The junk food is a reason for tired eyes for it hasn't enough vitamins（维生素）.

Less sleep causes the eyes to become heavy. Dark circles also develop if one doesn't get enough sleep over a period of time.

If not treated in time，the condition can become worse. Here are some ways to relieve（减轻）a tired eye condition.

Every hour during your day at work, spend a minute relaxing your eyes. Look away from your computer screen and roll your eyes in all directions. Try and blink（眨眼）more often. Look around the room or close your eyes for a minute if you want and then work again. Following these every hour will help relieve the stress on your eyes，and you won't feel so tired after work.

Tea helps relieve tired eyes. Make a cup of hot black tea and pour it into a glass. Hold the glass close to your eyes，so that the vapors from the tea reach your eyes. This will also make you feel fresh.

If your eyes feel very tired at work, go to the washroom and wash your face with cool tap water. The cold water will help relieve the tired feeling. Do this every hour during work and your eyes will feel good.
