AceShowbiz - Jennifer Aniston feels sleep is "beautiful." Struggling with insomnia for years, the 54-year-old actress has now grown to appreciate the value of sleeping well.

"Sleep is extraordinary. It's beautiful. But, boy, did I take it for granted when we were young. When you're younger, you kind of take it for granted. You think, 'I can survive on three-to-five hours of sleep and I feel great,' and then, all of a sudden, it just starts not to feel great and your performance isn't as up to par as it should be," she told InStyle.

Jennifer acknowledged that a lack of sleep can lead to other health problems. She said, "All of your body is getting all the work done that it put itself through during the day. You realise a lack of sleep leads to all sorts of health issues."

However, over the years, Jennifer has developed a routine that works well for her. She shared, "I don't push myself so hard [in a workout] because that will lead to an injury when your body and your brain aren't fully rested. I just try to do my best and just figure out everything possible that will ensure a good night's sleep."

Meanwhile, Jennifer previously revealed that she would "love a relationship." The actress doesn't "have any interest" in getting married again - but she's still hopeful of finding love. Asked if she would ever get married again, Jennifer - who was previously married to actors Brad Pitt and Justin Theroux - replied, "Never say never, but I don't have any interest."

"I'd love a relationship. Who knows? There are moments I want to just crawl up in a ball and say, 'I need support.' It would be wonderful to come home and fall into somebody's arms and say, 'That was a tough day.' "
