Studies Link Bad Sleep to Cancer
Two American studies link bad sleep to cancer. They looked at over 18 million Americans. They were aged 18 to 50. Many had insomnia. Insomnia means trouble sleeping. These people had more cancer in five years.
Cancer in young adults is rising around the world. Women with insomnia had three times more breast cancer. They also had more uterine and ovarian cancer. Men and women had more bowel cancer.
The studies do not prove sleep causes cancer. Experts say more work is needed. For now, do not smoke. Stay at a healthy weight.
