When it comes to getting a solid night's sleep, the usual advice is to have good sleep hygiene. You know, turn off those smartphone screens, give yourself some time to wind down, and try to stick to a regular sleep schedule. But there's stuff going on inside the body can affect how well you sleep, too. In fact, your hormones can play a pretty crucial role in how well you sleep at night.
Hormones are chemicals that tell your organs and your body what to do, says The Conversation, like when to go to sleep, when to wake up, how much to grow, and they even produce that "fight or flight" adrenaline response. Because hormones control your body's processes, they can affect your sleep in so many different ways.
"Hormonal changes can wreak havoc on sleep," Gina Shaw wrote for WebMD. "In turn, sleep deprivation can affect hormone levels in a sleepless vicious cycle. So when hormone levels spike or drop ... women may be more vulnerable to sleep problems." Here are just seven hormone fluctuations that could be affecting how well you're sleeping at night.
