This was basically the tactic he employed when he met with South Vietnamese heads of state in Guam during the Vietnam War. Media pundits presume that Obama was taking Provigil or Nuvigil, stimulants prescribed to help off excessive sleepiness, which would have been more effective for time zone management. This was his preferred method of dealing with the problem, especially when he had important meetings to deal with.
Four months after she resigned from her position, she quipped she was still jet lagged. Bush: I am still unclear if he ever left his ranch in Texas.

This usually resolves within one to two days, but can still disrupt certain functions of the body. Jet lag affects many travelers across the globe, from athletes to businesspeople. Crossing eight, nine, ten time zones at a time takes its toll on the human body. This article will share some of the experiences I have had and heard from physicians, athletes, trainers, and exercise physiologists from around the world, as well as research from The American Academy of Sleep.
My interest in how jet lag effects the body started when I was traveling regularly with a host of teams whose athletes were training for the Athens Olympics in 2004, the Beijing Olympics in 2008 and, most recently, for the 2012 London games. The experiences of our Olympic athletes this year will have far less strain on their circadian rhythms than the last few essay editing services uk games, but adaptation is necessary for proper performance at any level.
Besides our body time clock, other circadian rhythms control temperature, blood pressure and bowel movements. Most of our circadian rhythms are synchronized by the Earth's 24 hour light-dark cycle. The entire sleep-wake cycle is primarily influenced by the exposure to light. This has to do partly with the secretion of melatonin. It usually starts at 9 PM and stops at 7:30 AM. Light inhibits melatonin production and has been known to stimulate arousal. During jet lag, the internal sleep-wake cycle is essay editing services uk of phase with the local light-dark cycle, causing drowsiness or arousal.
Direction of travel has long been known to affect the severity of jet lag symptoms and the diurnal cycle. This translates into retarded or disrupted sleep on eastward flights more than westward flights. The easiest way to understand this is to know that travel eastward shortens the day, and all of travel's effects on the body require adaptation in a shorter time frame, which stresses the entire body's physiological clock. The body has a tendency to the 24 hour time cycle and cannot adapt that quickly. In total, the sleep-wake cycle needs two to three full days to attain homeostasis.
Sub-acute studies reveal the effects of jet lag peaking at three to four days upon westward travel. Eastward travel is more severe and can peak at the five to seven day mark. The effects of eastward travel seem to persist longer in any population, not only the athletic population. The rate of adjustment to a new time zone seems to be equal to one day for each time zone crossed. Travelers with more rigid and engrained sleep cycles usually have more jet lag symptoms than their more flexible counterparts.
Funny enough, early risers have less difficulty flying eastward, while night people who prefer to stay up late have less difficulty flying westward. Furthermore, people with higher levels of physical fitness adjust more quickly to changes in the sleep-wake cycle. Essay editing services uk and women tend to react similarly, with some exceptions. Men tend to go to sleep earlier essay editing services uk experience less fatigue after traveling ten time zones in an eastward direction, albeit they have elevated systolic blood pressures. However, non-exercising females are known to have disrupted menstrual cycles, while female athletes do not.
For some reason, older individuals may be less prone to the symptoms of jet lag because those over 60 have less regular circadian rhythms, lower core temps and melatonin rhythms. If they do experience jet lag, they have a greater difficulty coping, especially when traveling eastward.write my thesis paper best online essay writing service i need help writing a compare and contrast essay write my custom paper good customer service essay
