Sleep troubles could lead to prostate cancer
For men, tossing and turning through the night is not only robbing them of sleep but also could be putting them at a greater risk of cancer. A study published in the journal Cancer Epidemiology, Biomarkers & Prevention found that men who have trouble falling asleep and staying asleep each night have double the risk of developing prostate cancer as men who have no trouble sleeping.
The Icelandic study analyzed the sleeping patters of 2,102 men between ages 67 and 96. At the start of the study, the men were asked four questions about their sleeping habits: whether they took medicine to sleep, whether they had difficulty falling asleep, whether they woke up during the night with difficulty going back to sleep, whether they woke up early in the morning with a hard time going back to sleep.
Based on the answers, researchers found that 8.7 percent of respondents had severe sleep problems and 5.7 percent had very severe sleep problems. Then the participants were monitored for five years after they had answered the questions. After five years, 6.4 percent of the subjects had been diagnosed with prostate cancer.
After adjusting for age and other factors, the researchers found that the more trouble the men had sleeping, the higher their risk for prostate cancer. And the men with ‘very severe’ sleep issues were three times more likely to develop advanced prostate cancer.
