4. Lady Gaga
The famous pop singer struggles with fibromyalgia and post-traumatic stress disorder (PTSD) — conditions known to have a negative effect on sleep. In 2013, Gaga also revealed that she can’t sleep when making music because she gets so excited. In 2015, she told her Instagram followers that her thoughts can stop her from sleeping (she might find progressive muscle relaxation helpful). There’s no denying the pop star is, at the very least, extremely passionate about what she does. But all that drive has her tossing and turning at night, she told the UK’s OK! Magazine in 2010. “My passion is so strong I can’t sleep — I haven’t slept for three days,” she said. “I lie in bed and try to pray and breathe. I have a very overactive mind. ” Whether or not she really meant she’d been awake for a solid 72 hours or simply didn’t sleep well three nights in a row, sleep deprivation has real consequences. Among the most frightening is a decrease in reaction time, which, if you’re driving, could prove deadly.
