Getting up early in the morning is no easy task for plenty of people. That's why alarms are important-they ensure that you wake up at your desired time in the morning. However, nobody can deny how tempting it is to try and squeeze in a few more minutes of sleep.
About 57 percent of people snooze in the morning, which is defined as needing multiple alarms to wake up. If you set a single alarm and snooze it repeatedly or set several alarms at regular intervals until the time you absolutely need to gel up, you are a snoozer. Waking up on the first alarm is commonly recommended, but does it really make a difference if you are woken up by one alarm compared to several ones?
In a recent Sleep study, researchers examine how snoozing affects an individual's health and sleep. According to the study,people snooze for a variety of reasons. Most of the participants said that they just can't get up with only the first alarm. Some say they snooze because they feel comfortable in bed,while others do it because they feel less tired when they do get up.
The participants wore an activity tracker for the study, which allowed the authors to observe that snoozing is generally associated with lighter sleep in the last hour before waking up and a higher resting heart rate across the night. The study found that snooring isn't necessarily associated with decreased sleep duration,increased sleepiness or more naps. This suggests that there might not be much of difference between waking up on the first alarm or the subsequent ones when it comes to shorter sleep duration or daytime sleepiness. What might matter more is whether you are sleep-deprived in the first place or not.
Snoozing feels good because there is that pleasant feeling of falling back to sleep. However,the brain takes time to wake up and snoozing can interrupt that process, leaving you groggy for hours later, says DanielA.Baronem, associate medical director of the Weill Cornell Center for sleep Medicine and author of Let's Talk about Sleep. He suggests setting an alarm as late as possible and just waking up then, which allows you to get more sleep.
Practicing proper sleep hygiene may also help individuals avoid feeling tired and groggy. Mattingly recommends establishing a comfortable sleeping environment, which includes ensuring the absence of light during sleep forming regular sleep and wake routines on weekdays and weekends, and having daylight exposure during and after waking up.“The best advice is to sleep as much as your body needs, which allows the body to avoid grogginess all on its own.” Mattingly adds.

According to the passage, what is one of the recommended strategies to avoid feeling groggy after snoozing?( )
When you want to send a message to someone these days, all it takes is a few swipes of your finger on a smartphone. For thousands of years before the advent of instantaneous communication and the Internet,communication had to be done in much slower ways.
Writing letters and having them hand-delivered was probably the most basic and long-standing means of communication, but some people wanted to remove the human element entirely. Just as we now rely on wireless networks and microchips to do our heavy lifting, earlier generations used homing pigeons to deliver their messages across long distances. In movies and television, we have all seen homing pigeons (or ravens) delivering messages, but what is the story behind this bizarre ability?
While delivering messages on horseback or on foot was satisfactory, it also came with a lot of unpredictable variables. More than 3,000 years ago, the first such improvement on message delivery was made. when homing pigeons were first introduced. While studying the patterns and movements of birds,it appeared that they even after foraging, hunting and soaring for miles in every direction, they were able to guide themselves home.
Pigeons tend to be easy to get,quick to breed, and highly “in tune ”with their sense of direction. In particular rock pigeons were chosen and interbred to create homing pigeons,essentially birds that could find their way home. These pigeons would be trained very carefully, gradually being taken further and further from its “nest”before being released and flying home. In this way, pigeons could be programmed to fly home from a range of different locations. Pigeons could use visual cues, like natural landmarks, and gradually develop a known path back to its home base,
Unfortunately, this meant manually transporting large amounts of pigeons in one direction, before having them released with a message attached to their leg, hoping that they would return to the original location.
These messages were typically small rolls of parchment or paper, stored in a small glass or metal tube. Once the message was written and stored, the homing pigeon would be released to fly home, thus delivering the message on time and skipping over traffic,natural, disasters, divulging, dishonesty, and human error.
Now, rock pigeons were particularly gifted in this homing ability due to their strong magnetoreception skills. For those of you who don't know magnetoreception is an innate ability in certain life forms to defect and orient themselves based on magnetic fields.
Rock pigeons that showed the strongest ability were bred to create powerful and reliable homing pigeons!Interestingly enough it has been found that homing pigeons are much more accurate going long distances in the north and south direction ,rather than east and west,due to the natural diree-tion of the magnetic fields( flowing between the North Pole and South Pole).
Which of the following is NOT mentioned as a method of communication before the advent of instantaneous communication and the Internet?( )
