How to avoid jet lag?
I know lots of people love travelling, but travelling to a new time zone can result in jet lag. Personally I did so much business travelling in my late 20’s and then in my 30’s I travelled for pleasure, that more recently I have been happy to stay put in England and simply pop over to Europe when I wanted some sun. This year I am planing to go on a training course in Canada so when I saw some recent research on avoiding jet lag it caught my eye.
Jet lag occurs when your circadian rhythms are slow to adjust to the new time zone and remain on their original biological schedule for several days. This results in your body telling you it is time to sleep, when it’s actually the middle of the afternoon, or it makes you want to stay awake when it is late at night.
Here are some tips for minimizing the occurrence of jet lag:
- Select a flight that allows early evening arrival and stay up until 10 p.m. local time. (If you must sleep during the day, take a short nap in the early afternoon, but no longer than two hours. Set an alarm to be sure not to over sleep.)
- Avoid alcohol or caffeine at least three to four hours before bedtime. Both act as “stimulants” and prevent sleep.
- Try to get outside in the sunlight whenever possible. Daylight is a powerful stimulant for regulating the biological clock. (Staying indoors worsens jet lag.)
- On the flight set the time on your watch to the local time of your destination so you can mentally start adjusting to the new time zone.
- When you arrive eat with the locals.
Traditionally people have just slept off jet lag. Recently university researchers in Surrey tested their theory that instead of sleeping, you should start eating meals at the same time as the locals. They tested the theory on 60 long haul cabin crew workers, who either ate meals regularly on their days off in the destination city or followed no meal plan and ate when they felt like it. Although both groups suffered some jet lag, the symptoms were less severe among those who followed a regular meal plan based on the local time. They were also more alert.

Natural ways to reduce anxiety – Part 5
Having looked at exercise (yoga) and breathing I now want to move on to look at nurtition. Studies of animals suggest that the amino acids L-lysine and L-arginine may influence neurotransmitters involved in stress and anxiety. In humans supplementing with the two together appears to reduce both state anxiety (temporary anxious feelings that arise when comfronted by a specific situation) and trait anxiety (a general tendancy to be anxious) in healthy men and women subjected to stressful situations. Taking L-lysine alone has also been shown to reduce chronic anxiety in people with low dietary intake of the amino acid.

Power Poses
Like most people I am interested in body language. Like most people I noticed awkward social interactions in day to day life. Until recently I considered that body language is about
- what you are communicating others
- what they are communicating to you
By adopting the Wonder Woman pose for 2 minutes, social scientists have proven that it will increase your confidence, assertiveness and help you feel more comfortable in a situation. This is due to the impact holding this "high power" pose for two minutes has on your body, its reduces your cortisol levels and increases your testosterone levels. Meaning you are less reactive to stressful situations.
So can you apply this in real life. Last weekend I was on my sports massage course and each weekend we have a written test we need to pass. For some reason I had misunderstood what the test was on and forgot to review the whole subject. I discovered this about 30 minutes before the test. So I was in a highly stressful situation. So I decided to give this power pose a try and did it during the next 30 minutes while revising. The science says 2 minutes but I felt I needed all the help I could get. It turns out that I passed. While this isn't irrevocable proof, I would recommend people try it.
As Amy Cuddy says "our body's change our minds, our minds change our behavior and our behavior changes our outcomes." For a more detailed understanding of power poses, the science behind them, watch Amy Cuddy's Your body language shapes who you are.
So you thought you knew what causes hardening of arteries … think again
The standard theory of heart disease states that fatty foods cause the arteries to "clog up" and narrow, which is a major feature of cardiovascular disease. Researchers have discovered that a lack of sleep seem to have more to do with hardening of the arteries (atherosclerosis) than a fatty diet. Not getting enough sleep on a regular basis can cause a buildup of plaque in the arteries, which causes them to stiffen and eventually close. Researchers at Massachusetts General Hospital now think that hardening of arteries has more to do with a "neuro-immune axis" linking sleep to the cardiovascular system. Sleep helps regulate the production of inflammatory cells and maintain healthy blood vessels, and so it would follow that lack of sleep has the reverse effect. The researchers demonstrated the effect on a group of laboratory mice. Although the cholesteral levels of sleep deprived ice remained the same, they developed larger arterial plaques and had double the number of inflammatory cells known to contribute to hardening of arteries.
