Your hormones might not be something you can readily see, but you can definitely feel when they’re amiss. Hormones refer to the chemical messengers in your body that affect everything from your metabolism to mood and sexual function.
Endocrine glands—the pituitary, thyroid, and adrenal glands, among others—are at the helm of hormonal production. “Everything in our body is controlled by hormones—your temperature, hunger, satiety, sleepiness, fat storage or burn, stress response, and more. Rather than acting independently of each other, our body’s hormones are constantly interacting in a very delicate balance with each other,” explains former Parsley health coach Danielle DeSimone.
And we, in part, have control over that balance, as there are many lifestyle habits and environmental factors that can affect hormone function and production. When too much or too little of a hormone is produced, it can send your body out of whack. “When hormones are balanced, our bodies run like a well-oiled machine. But when one aspect of hormonal health is off-balance, it’s like a domino effect that can cause negative consequences in many other areas,” says DeSimone.
Here are some common factors that may affect your hormonal health—and what you can do to get things back on track.
Poor sleep
Poor sleep can mean a lot of things. It might mean that you’re not getting enough of it. Maybe, despite being in bed for 8 hours per night, you’re getting poor quality of sleep, so you wake up feeling groggy and unrefreshed. Either can affect your hormone function in a variety of ways.
“One night of poor sleep—defined as less than six hours—makes the body more resistant to the effects of insulin the next day,” says DeSimone. Insulin is a hormone secreted by the pancreas in response to the rise in blood sugar that happens after eating. When insulin is released, it helps push glucose from the bloodstream into cells, which ultimately gives you energy.
“Normally, just enough insulin is secreted to help store glucose in our cells for energy, and then it leaves our bloodstream until the next meal or snack,” DeSimone says. But insulin resistance means cells don’t normally respond to insulin—it leaves things akin to a noisy neighbor who’s constantly knocking on your door (but no one’s responding), she describes. When glucose can’t enter cells, it sits in the bloodstream, which creates more insulin release. Over time, this can lead to insulin resistance that’s implicated with many chronic health conditions.
Not only that, but poor sleep also skews hunger and fullness hormones like leptin and ghrelin, which have the role of telling you when to eat and when to stop. You might notice that after a night of poor sleep, you’re feeling more snacky—and those snacks are more of the processed, sugary kind.
And because sleep is such a big factor in hormonal health, there’s one more issue to cover, and that’s its effect on the stress hormone cortisol. “When we’re sleep deprived cortisol increases, especially later in the day when it should be tapering down to prepare for quality sleep. This not only causes trouble sleeping and can lead to the ‘tired but wired’ feeling many of us experience,” says DeSimone. Increased cortisol levels also prompt your body to prioritize fat storage and burn muscle tissue, ultimately leading to weight gain, she says.
