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.

Holistic holiday first aid kit – part 1
I am off to Japan soon which inspired this blog article. So I wanted to share with you some ideas about a holiday first aid kit. The first thing I pack is rescue remedy which relieves stress and anxiety - I basically pack this in case flights get cancelled, luggage gets lost etc. The next thing I pack is Traumeel, in case I get a soft tissue injury i.e. sprain or strain. Traumeel is a homeopathic combination preparation that reduces inflammation, swelling, and oozing. The pharmacology involved is not yet understood. Studies suggest the drug modifies the action of neutrophils and the release of inflammatory mediators. Injected locally, its analgesic effect is comparable to steroids but without the risks of tendon rupture or skin depigmentation. I personally take tablets or use a cream because I am whimp who doesn't like the idea of injecting herself. Plus I don't think its very practical to try and take an injection kit through an airport! Traumeel has been available for eighty years and is suitable for frequent use, with the only contraindication being adverse allergic reaction. Among elite athletes its use is common and anecdotally it attracts very favorable reports. There is data to suggest comparable efficacy of both topical and injected Traumeel when compared with Nonsteroidal anti-inflammatory drug therapy, with fewer side effects and greater patient satisfaction.

Does mindfulness meditation help you if you are depressed?
Mindfullness is very trendy right now because it is claimed to help you cope with anxiety and stress and build resilience. But does it help you if you are depressed? This is the question that researchers from Northwestern University Feinberg School of Medicine tried to answer in a recent study. During the study, 31 women most of whom had done nothing to help themselves to deal with their depression in the last 12 months, participated in an mindfullness group. They practicied mindfullness meditation and yoga on average 150 minutes per week. Before starting the study 45% said they had no experience of mediation and 71% said they had never tried yoga. The primary outcome, depression and secondary outcomes (stress, mindfulness, functioning, well-being and depression stigma) were assessed at start of the study and then again at weeks 8 and 16 weeks . The depressive symptoms significantly decreased during the study, in addition the stigma of depression increased from the start of the study to 8 weeks and then significantly decreased between 8 to 16 weeks of the study. A significant decrease in stress and significant increase in mindfulness was found at week 8 and the end of the study when compared to the start of the study. In addition, the women reported increased sense of well-being including self-acceptance and growth. In conclusion mindfulness medication can reduce levels of depression and stress as much as powerful drugs and psychotherapy do.

The relationship between vitamin D and your immune system
A growing body of scientific evidence shows that vitamin D plays a crucial role in disease prevention and maintaining optimal health. You have about 30,000 genes in your body and vitamin D affects nearly 3,000. This is in addition to all the vitamin D receptors through out your body. Inflammation is the body's attempt at self-protection; the aim being to remove harmful stimuli, including damaged cells, irritants, or pathogens. While inflammation is a vital part of the body's immune response, it can also be problematic and plays a role in some chronic diseases e.g asthma, arthritis. Researchers investigated specific signalling events that vitamin D suppresses in order to inhibit inflammation. Research published in The Journal of Immunology called it the "inflammatory cascade"; low vitamin D levels failed to inhibit the cascade while adequate levels did the job. Researchers concluded that patients with chronic inflammatory diseases who are also vitamin D deficient may benefit from supplementation. Researchers in Turkey, reported in the international Journal of Rheumatic Diseases that chronic widespread musculoskeletal pain is improved with vitamin D. Fibromyalgia sufferers and other patients with chronic widespread musculoskeletal pain were given 50,000 iu/week oral vitamin D3 for three months. Afterwards scientists discovered decreases in pain, fatigue upon awaking, lack of energy, tender points and depression. Significantly there were 30 Fibromyalgia patients at the beginning of the study and only 20 at the end! Next week I want to look at the relationship between low vitamin D levels and common ailments.
