Jennifer Aniston recently revealed that she has suffered from sleep problems for decades, ranging from insomnia to sleepwalking. "I think it started somewhere in my 30’s or even earlier, but you just don't start to notice the effects of a lack of sleep when we're younger because we're so invincible," she told People in an interview. "It began as something that I would just accept and then all of a sudden you realise the effects of your lack of sleep and how it affects your day, your work, your mind function and your physique." The Friends alum said she would try to go to sleep and would wind up just watching the clock. She added she even sleepwalked at times, a habit she has now dropped, she thinks. "I've been woken up by house alarms going off that I've set off," she admitted, "And I don't think I do that anymore. That was when I was super sleep deprived." The Morning Show star said she initially put off seeking treatment for her sleep issues, but in the last few years, she realised she needed some serious help.
