What You Need to Know Before You Go to Alaska

Note: If your journey includes travel in Alaska’s high altitude(海拔)regions, you may experience altitude sickness. Please consult your health care provider for suggestions on prevention and treatment.

Because of its vast size, a wide variation of climates is found across Alaska. In the interior(内陆)temperatures can exceed 90°F during summer, while the southeast and south-central coastal regions will average 55°F to 70°F. While daytime temperatures can be quite warm nights can be very cool. Use a website such as weather: com to find out the average temperatures and rainfall during your travel time

During your tour you will be exposed to the weather. As Abercrombie and Kent (A&K)programs to Alaska operate in summer, exposure to the sun is the most common concern, but cold days are also possible at any time of year. Pay special attention to the clothing suggestions and check the weather before your trip.

National parks and their surrounding areas are often home to a few troublesome plants and insects Poison oak(毒葛 )is one such plant o look out for. Your guides will help you identify t if you’re not sure what to Took for. If you come into contact with it, it is very important to wash with soap and water as quickly as possible. Keep in mind that the irritating oils from the plant are easily transferred from you, your clothing or equipment to other people or equipment, so even if you're not sensitive it is important to consider others.

The mosquito population in summer is quite high. The mosquitoes are large and aggressive. Be certain to pack insect repellent(驱虫剂 ) Those who are more sensitive to mosquitoes may also consider bringing head netting

A new pastor(牧师) named John reopened a church that had been abandoned in a suburb. He found it broken, and in need of a lot of repair work. His goal was to have everything done in time for his first service on Christmas Eve.

He worked hard. However, when John went to the church on Dec. 21, his heart sank: a large area of plaster (石膏) had fallen off the front wall due to a terrible storm the night before. John headed home, and on the way he stopped at a market selling items for charity.

One of the items was an exquisite( 精致的)handmade tablecloth. It was just the right size to cover up the hole in the front wall. He bought it and headed back to the church. It started to snow. An old woman had missed her bus, and he invited her to wait in the warm church for the next one. As John put up the tablecloth the woman asked him to check the corner for the initials(手写字母). They were her initials: she had made this tablecloth 35 years before. Then the war broke out, and forced her to part with her husband.

John wanted to give her the tablecloth. but she asked him to keep it for the church. John insisted on driving her home which he thought was the least he could do.

What a wonderful service he had on Christmas Eve! John noticed one old man staring at the tablecloth on the front wall. The man said it was similar to one that his wife had made many years before.

John brought the old man to the house where he had taken the woman three days earlier. He helped him climb the three flights of stairs to her apartment, and saw the greatest Christmas reunion he could ever have imagined.

Some people have tried locking their mobiles away in order to fight against their smartphone addiction(上瘾), while others have used some tricks such as making their screens black and white. But the cure to smartphone addiction may lie in an app that rewards users for leaving their phone alone.

The new app, called Hold, can detect(检测)when users have used their smartphones and gives them points dependent on how long they avoid the temptation(引诱)of looking at Facebook, for example. Upon downloading it for free, users receive 10 points for every 20 minutes spent without touching their phone between 7: 00 and 23: 00 every day of the week, with a user email address needed to receive the rewards. To get half price Vue cinema tickets, users need 60 points. For two free coffees from Cafe Nero, users need 300 points, and a glass of juice for 90 points, For £5   Amazon vouchers(代金券)users need to have collected 1, 000 points.

Hold was created by Maths Mathisen, Florian Winder and Vinoth Vinaya-three Norwegians. They noticed that young people's dependence on their smartphones was getting out of hand while studying at Copenhagen Business School. Rather than punish their users, the three found that the best way to get them to put their phones down was to use tricks that got them interested in the first place.

Lots of studies in recent years point to the worrying rise of smartphone addiction and the effects of smartphones on education. Researchers from the London School of Economics found that students who did mot use their phones at school found their grades improved by 6.5 percent.

Cafe Nero, Amazon and Planet Organic will also offer discounts on the Hold marketplace. Students will also be offered the choice to use points to buy school books which are then donated to some schools.

Many students give up sleep to get good grades: but research shows that students should do the opposite.

It's no secret that college students tend to reduce sleep to squeeze the most out of 24 hours. But this generation is different, and researchers are increasingly focusing on college students because they are one of the most populations lack of sleep. College students go to bed one to two hours later and sleep less per night on average compared to previous generations. As a result, 75% of undergraduates did not sleep enough to feel rested on five or more days per week, and 19% reported that sleep difficulties had an influence on academic（学业） performance in the past year.

The amount of sleep that a college student gets is one of the strongest predictors of academic success. Sleep plays a key role in helping students fix and Improve memories. while preventing drops in memory. Without sleep, people work harder but don't do as well.

Members of the Student Health Advisory Council(SHAC)consulted famous sleep researchers and gave suggestions to University Health Service（UHS） clinicians（临床医师） on how to address sleep with student patient. Here are some suggestions for UHS clinicians to consider in their work with students.

Encourage students to adjust(调整)wake-up time, as it may be easier to adjust than bedtime.

Emphasize( 强调)behavioral changes to improve sleep. Medicine is rarely. Students can practice relaxation techniques before bed to increase quality of sleep, avoid doing homework immediately before(or in)bed, and avoid TV and computer use before bed.

Encourage napping, Most students don’t get a full night sleep every night, and naps help them make up the difference. Research shows that napping for 10-45 minutes(before entering REM sleep)can increase performance.

Advise students to avoid caffeine, especially later in the afternoon or night.
