What do you have to say about flying? A hell of a lot more people per year are affected by jet lag.

Jet lag causes actual physical damage to the brain.

DST stinks it takes a few days for your body to adjust until then you are more prone to accidents, I wonder how many people have died in car wrecks and accidents at work and other such things, because there body have not quite adjusted to DST.
it is a stupid masochistic and dangerous BS we pull on are selves.
It is just plain stupid for no real reason

The Monday and Tuesday after moving the clocks ahead one hour in March is associated with a 10 percent increase in the risk of having a heart attack," says UAB Associate Professor Martin Young, Ph.D., in the Division of Cardiovascular Disease. "The opposite is true when falling back in October. This risk decreases by about 10 percent."

Exactly why this happens is not known but there are several theories," Young says. "Sleep deprivation, the body's circadian clock and immune responses all can come into play when considering reasons that changing the time by an hour can be detrimental to someone's health."

"Every cell in the body has its own clock that allows it to anticipate when something is going to happen and prepare for it. When there is a shift in one's environment, such as springing forward, it takes a while for the cells to readjust. It's comparable to knowing that you have a meeting at 2 p.m. and having time to prepare your presentation instead of being told at the last minute and not being able to prepare. The internal clocks in each cell can prepare it for stress or a stimulus. When time moves forward, cell clocks are anticipating another hour to sleep that they won't get, and the negative impact of the stress worsens; it has a much more detrimental effect on the body."

Immune function

"Immune cells have a clock, and the immune response depends greatly on the time of day. In animal studies, when a mouse is given a sub-lethal dose of LPS, an endotoxin that elicits strong immune responses in animals, the mouse's survival depends upon the time of day they were given this endotoxin. Mice that were put through a phased advance much like Daylight Savings Time, and then had a challenge to their immune system, died, whereas the control animals that were not subjected to a phased advance survive when given the same dose of LPS, showing how an acute time change can be detrimental to the immune system response."

Luckily, the body's clock eventually synchs with the environment,

On car accidents

" the spring shift to daylight savings time, and the concomitant loss of one hour of sleep, resulted in an average increase in traffic accidents of approximately 8 percent.

Jetlag 'shrinks the brain'

Frequent flyers who repeatedly suffer jetlag could be permanently affecting their brain power, claim researchers.

The study, published in the journal Nature Neuroscience, examined the brains of aircrew, but suggests that any worker who swaps from night to day shifts over a short period may be at risk.
et lag happens when a traveller passes over a number of time zones and disrupts the normal "circadian" rhythms which help humans wake up in the morning and go to sleep at night.
Dr Kwangwook Cho of the University of Bristol conducted a small study of 20 women, aged between 22 and 28, who had worked for at least five years for an airline, and regularly flew across at least seven time zones.

Half of the women, however, had on average least a fortnight to recover from their jetlag - the rest had only a week.

Women were chosen for the test because, in general, they suffer far worse jetlag than their male counterparts.

Memory tests

Dr Cho not only scanned their brains to look at their physical characteristics, but also measured their performance in memory and understanding tests.

He found that the aircrew given the shorter period to "turn around" after a jet-lagging flight had an area of the brain called the temporal lobe which was noticeably smaller than the others.
Dr Cho said: "I found there was no deficit of language, but certain short-term objective memory and very simple abstract cognition was quite bad."
