Sunbathing Cuts the Blood Clots Risk

Mar 26, 2009
Can sunbathing be good for you? A new study shows that exposure to sun lowers the risk of developing blood clots.

Scientists at Lund University, Sweden conducted a twelve-year-old study to analyze the sunbathing habits of 40, 000 women from 1990. They asked the participants whether they sunbathed in summer and in winter and the place they used to sunbathe, and followed the women's medical history. At the end of the study, as much as 312 women had thrombosis.

The results of the study showed that women, who sunbathed, were 30 percent less likely to develop blood clots, taking into account other factors like exercising, smoking and alcohol habits.

According to the findings, vitamin D, which is produced during sunbathing, lowers the risk of blood clots, but the mechanism is not well-understood. Further research is needed to find out how vitamin D contributes to reduced risk of blood clots.

Previous studies linked sun exposure to the increased risk of skin cancer. Swedish scientists pointed out that moderate sun exposure overweighs the risk of skin cancer. People should go out every day even in the afternoon for short time, but should avoid sunburns.
The study in the Archives of Internal Medicine found that people with vitamin D deficiency have the higher risk of death from heart disease. Vitamin D also is known to protect against such health conditions as osteoporosis, breast cancer, prostate and colon cancer, depression, sleep deprivation and immune system disorders.

Blood clots can lead to many health complicatons including stroke and are more common among inactive and/or obese individuals.

Blood clots are life threatening however exercise can help prevent their formation and assist in dissoving of existing clots. This fact was discovered and presented to the American Heart association in 2003 by the University of Colorado Health Sciences Center.

The study found that levels of an essential blood clot dissolver known as tissue type plaminogen activator (t-PA) are greatly diminished in overweight men (by as much as 30%). This reduced protection in the blood stream leads eventually to problems with blood clots.

Walking for a period of three months for a mere 45 minutes a day, five days a week however increased the amount of t-PA in the obese participants blood by as much as 50%. The study showed that after this walking regimine the obese subjects had similar levels of t-PA in their blood to that of lean participants in the study.
