A new study identified several chemicals that may be linked to earlier menopause.
Researchers found women with the highest levels of these chemicals went through menopause between two and four years sooner than those with the lowest levels.
While most of these chemicals have been banned in the U.S. or rarely used, many may still linger in the environment.
Scientists said some bodies may handle these chemicals differently than others.
Another study suggested people who binge-watch television are more likely to be lonely and depressed.
Researchers surveyed more than 300 young adults on their mental health and TV habits.
They found lonely and depressed participants spent more hours watching TV in order to escape from negative feelings.
Experts say binge watching is linked to fatigue and obesity and may even cause people to neglect their work and relationships.
