Can't Sleep? Your Hormones May Be The Reason + 7 Supplements To Try For A Better Nights Sleep

Updated: Jun 30, 2023

A good night’s sleep plays such an important role in managing our happiness, energy levels, and overall well-being. Getting enough sleep can truly determine whether your day will be “productive and a breeze” or “I have to drag myself to work” kind of day… we’ve all been there.

Sleep and hormone regulation go hand in hand. Without quality sleep, our bodies are unable to regulate hormones properly which leads to fatigue, weight gain, increased hunger, and anxiety.

At the same time, certain hormones interfere with sleep. It’s a double-sided arrow.

So where do we start? Let’s jump right in and discuss hormones.

Hormones that interfere with sleep

There are four main hormones that play an important role in sleep:

cortisol, estrogen, progesterone, and melatonin.


Cortisol levels are supposed to be at their highest in the morning and gradually drop throughout the day until bedtime, this is when they are at their lowest. This allows your body to ease into relaxation and promotes quality sleep.

When having trouble sleeping, it can be because cortisol is high and low at the wrong times. Often this means levels begin increasing at night instead of in the morning. This can be caused by caffeine and alcohol intake, late-night exercise, anxiety, and stress or can be the result of a hormone imbalance.

Low Estrogen

Since estrogen helps to promote sleep, low estrogen makes it difficult to fall asleep and stay asleep. You might also experience hormonal symptoms like night sweats that wake you up. There are many causes of low estrogen, some include stress, poor diet, and over-exercising. Learn more about low estrogen in my previous blog here.

Low Progesterone

Progesterone and cortisol go hand in hand. Often, when progesterone is low cortisol is high. Progesterone aids relaxation and promotes quality sleep. Managing cortisol levels is the best way to also manage progesterone.

Low Melatonin

This is the most popular hormone when discussing sleep, and for good reason. When balanced, melatonin allows our body temperature to decrease and our eyelids to feel heavy. This creates the perfect feeling of relaxation which helps us fall asleep, stay asleep, and wake up rested.

Melatonin is produced naturally by our body when in balance. It has a close relationship with our body’s circadian rhythm. This is our 24-hour internal clock which signals when we rise with the sun and sleep when it sets. This can be disrupted during daylight savings time or when we travel in different time zones. During these times, melatonin is out of balance which affects sleep. Often, people will supplement with melatonin to help. But this is just a temporary solution for a hormone imbalance issue.

Lifestyle Tips to Support a More Restful Sleep

  1. Reduce caffeine and alcohol intake. Avoid caffeine after 1 pm.

  2. Follow a consistent sleep schedule. Wake up and go to sleep at the same time every day.

  3. Get morning sunshine to help boost your energy and support your circadian rhythm.

  4. Create a bedtime routine: Avoid technology at least 1 hr before bed, take a warm bath with Epsom salts, meditate, read, drink warm sleepy tea etc.
