The four main elements we rely on for our lives and wellbeing are air, water, earth and sunlight. If we take any of these forces away, then quite simply, we would not exist! There would be no life without the sun – but life with too much sun may not be good either. Ultraviolet rays – UVC, UVB and UVA – are emitted by the sun. UVC rays, the most dangerous to the human system, are filtered out by the upper atmosphere but some UVB (which can cause sunburn and eye damage) and UVA, reach the earth’s surface. The intensity depends on the angle of the sun – ie the geographical position, season and time of day. UV levels can increase by up to 50% between 11am and 1pm! UV is invisible. People outdoors are exposed to varying levels of UV and they are often unaware of the UV intensity. Unfortunately, warnings of sunburn often come too late. A survey in Denmark revealed that beach sunbathers exposed themselves for an average of three-and-a-half hours a day. Sunbed lamps simulate the sun and emit UVA and UVB but they go a stage further and control the output with a balance of UV to minimise the risk of burning and maximise the tanning. As we know – no-one controls the sun! Sunbed lamp technology is subject to on-going research and development programmes to keep abreast of researched evidence on the effects of UV.
7% of the UK’s adult population uses a sunbed = over 3 million people 70% of people want to be tanned 95% of sunbed users do not exceed the European Standard on maximum number of sessions per annum 88% of the UK population has skin types that can tan successfully in a controlled environment 38% of sunbed users do so for a pre-holiday tan. 83% of sunbed users claim to be quite or very knowledgeable of the possible risks from over-exposure to UV. Source: Consumer Research on Sun tanning and Sunbeds, The Sunbed Association, UK, 1997, conducted by Taylor Nelson with a sample base of 6143 adults. The main benefit of being tanned is seen as looking and feeling healthier. The main reason for using a sunbed is for a pre-holiday tan. Whilst the sun protection factor from a sunbed tan does not provide total protection, people having a base tan are less likely to over-expose themselves during the initial days of a holiday.
Vitamin D – Facts
Vitamin D is essential for good health. Medical studies around the world have proven the benefits of Vitamin D in association with:
- Cellular Health: including breast, colon and prostate cancers
- Bone Health: including osteoporosis, hip fractures, osteomalacia and hip fractures
- Organ Health: including high blood pressure, hypertension and heart disease
- Mental Health: including SAD, PMS, depression and general mood
- Auto-immune Diseases: including multiple sclerosis, Type 1 diabetes and rheumatoid arthritis
- Skin Disorders: including psoriasis
- Obesity and exercise programmes
- Sunlight is the most effective way for the body to manufacture Vitamin D. Yet in the UK and Ireland, our bodies can only manufacture Vitamin D from exposure to the sun during the months of May to October. Outside of these months, the sun is simply not strong enough.
Considered by many to be the foremost authority on Vitamin D, Dr Michael Holick (Professor of medicine, physiology and biophysics at the Boston University School of Medicine, one of the USA’s top universities), recommends a daily amount of 1,000 IU is necessary to maintain a healthy level. It is very difficult to eat enough Vitamin D rich foods on a daily basis to achieve these levels. Most multi-vitamin supplements only provide 400IU of Vitamin D. Unprotected UV exposure to 25% of 1 MED, 2-3 times a week is recommended by Dr Holick to ensure sufficient Vitamin D levels. Depending on skin type, this is the equivalent of about 5 minutes of unprotected UV exposure 2-3 times a week. In natural sunlight the word ‘unprotected’ is very important, as SPF creams reduce the ability of the body to produce Vitamin D from UV exposure by up to 97%.
Are you more at risk from Vitamin D deficiency?
Age: The older you are, the harder it is for your skin to make Vitamin D from sunlight. Lifestyle: The more time you spend indoors during daylight hours, the less opportunity you have to make Vitamin D. Geographical Location: In the UK and Ireland with its relatively long winters, you get less sun over the course of the year because the sunlight isn’t strong enough to make Vitamin D in the winter. Race: People with very dark skin, especially those of Asian and Afro-Caribbean descent find it difficult to make Vitamin D from limited sunlight. Culture: Certain cultures require their women to cover themselves entirely in heavy clothing that blocks out the sun. Intestinal Diseases: For people with Crohn’s disease, cystic fibrosis and certain other intestinal diseases, as the intestine cannot efficiently absorb Vitamin D from the diet or supplement.
