Most living things have a 24-hour body clock, and the body’s circadian rhythm is tied to it. When we sleep and when we wake up is regulated by our circadian rhythm. It is tightly linked to the rotation of the earth and gets reset every day by the sun’s light-dark cycle. Although we don’t have total control over our body’s circadian rhythm, there are a few things you can do to ensure a better night’s rest.

Dim the lights before bedtime

Your circadian rhythm is influenced by outside factors like light and dark. Dimming the lights helps signal to the body that it’s time to go to sleep. As the lights dim, our bodies start to naturally produce the sleep hormone, melatonin, which is secreted by the pineal gland in response to the darkness.

Reduce your exposure to blue light

Blue light shifts our sleep rhythm and tricks us into thinking we are still meant be awake. In addition to shifting our circadian rhythm, spending time on our devices can trigger the release of dopamine, the hormone that makes us happy… making it harder to put our phones down and fall asleep.

Wake up and fall asleep at the same time every day

Here’s looking at you weekend! Yes, even on the weekend. An inconsistent sleep schedule is confusing to your circadian rhythm. Getting up and going to bed at the same time each day helps us synchronize our biological clocks.

Expose yourself to bright light first thing in the morning

Sunlight creates increase alertness ,and it signals to our bodies that it’s time to get up . If sunlight isn’t available first thing when you wake up (like in the winter), turn the lights on bright.

Try a natural sleep aid

CBD:

has a calming effect on the nervous system

can alter mood because it affects the serotonin system
reduces anxiety, which can contribute to poor sleep quality

Valerian:

Helps manage anxiety + insomnia

Chamomile:

An herbal remedy with a calming effect
Helps you feel more prepared for sleep

Melatonin:

Hormone produced by the pineal gland in the center of your brain and is responsible for regulating your body’s circadian rhythm
Decreases the time it takes to fall asleep

Magnesium:

Activates your parasympathetic nervous system, the system responsible for getting you calm and relaxed
Regulates the hormone melatonin, which manages your natural sleep cycle

***Always consult your doctor first before taking any supplements***

Don’t be too rigid

Nobody is perfect, but it’s important to use these tips as a guideline. If you want to identify your circadian rhythm, try observing your body’s natural wake time by not using an alarm for a few days or even a week.

When you think about ways to get better sleep, what comes to mind first? Taking melatonin supplements, limiting blue light from screens/devices, and establishing a consistent sleep routine are often some of the ways we try to intervene on our sleep patterns. We don’t often think of our diet as a place to promote better sleep, but there is interesting evidence that certain foods can help us tend to our sleep, without needing to take additional supplements or drastically change our habits.

Imagine in your mind a traditional Thanksgiving meal. If yours included turkey, you also probably experienced sleepiness soon after the meal. While some of this tiredness is likely due to eating large meals at Thanksgiving, the consumption of turkey also had an impact on feeling sleepy. This is because turkey is a food containing high amounts of tryptophan, an amino acid that is prevalent in protein-rich foods. It is a precursor to the release of melatonin and serotonin, which both influence sleep.

Research has shown that people with low levels of tryptophan often experience anxiety, worry thoughts, and tension, which can all lead to low moods and trouble falling asleep. By increasing tryptophan consumption via foods, we can encourage our pineal gland to naturally produce melatonin, which can help you fall asleep faster and stay asleep longer. If you’re finding it difficult to get good sleep right now, or if anxiety is impacting your ability to fall and stay asleep, consider adding tryptophan-rich foods into your diet.

Foods High In Tryptophan:

Eggs (especially the yolks)

Cheese

Pineapple

Tofu

Salmon

Spinach

Nuts and Seeds

Turkey

Chicken

In order to get the most benefit from eating tryptophan-rich foods, it is encouraged to pair these with healthy carbs. Carbs promote the release of insulin, which leads to amino acid absorption, allowing tryptophan (an amino acid) to remain in the bloodstream. Try to include brown rice, oatmeal, fruits, vegetables, and whole-grain foods with your meals to reap the benefits of eating foods high in tryptophan. By mindfully adding some of these foods into your diet, we hope you will start to notice positive changes in your sleep quality.
