If you want better sleep, then sleep hygiene is your best option.
I have been a physician for thirty years now, and I still find that sleep is one of the most underestimated medicines we have. It is free, it is powerful, and for those of us living with an Autoimmune Condition, it is not optional. Deep, consistent sleep is where the body does its quiet repair work — and that repair is the whole point of the Epigenetic Autoimmune Protocol (the Epi-AIP).
Sleep sits at the heart of the Third Pillar of the Epi-AIP: Physical Fitness, Rest, and Sleep. And it belongs squarely in Phase One, Rest and Recover, where we treat rest not as laziness but as active healing — what I like to call the importance of winter. Nothing grows in spring that was not restored over winter.
So let me walk you through what sleep hygiene actually looks like in practice.
First, Understand Your Situation
Depending on how complicated your particular form of insomnia is, you may or may not need to follow every guideline below. The length of time each one takes is different too, but you will need to commit for as long as it takes to regain a normal circadian rhythm.
- If you have hypoglycemia, cortisol resistance, or another kind of hormonal imbalance, you will likely need all of the guidelines below, plus specific treatment for your condition.
- If you have an Autoimmune Condition, the metabolic instability, excess stress hormones, and the chronic inflammation that follows are your biggest challenges in slowing your illness down. Sleep is one of your strongest levers.
- If you have only a mild bout of insomnia from recent stress, a schedule change, or travel, you may only need a few of these guidelines for a short while.
Whatever your situation — or even if you simply want to sleep better to feel better — the first job is to restore your circadian rhythm.
This takes patience and dedication. Start with as many guidelines as you can fit into your life without adding more distress, and as each becomes a normal part of your day, gradually add the rest. Adjusting your circadian rhythm is not easy for your deeper physiology, because it treats any change as a stressor. These are tried-and-true methods, grounded in what we understand about human evolution and what modern research has shown to work.
A gentle note before we begin — if you are dealing with serious, long-standing insomnia, or you suspect sleep apnea, please see a qualified professional. Sleep hygiene supports good medical care; it does not replace it.
Create an Extended Sleep Schedule
This is as simple as it gets, and it may be the hardest thing to be consistent about. Consistency is exactly what it requires.
To inform your body that you are serious about sleep, be in bed for 9 to 10 hours a night — every night.
- If you keep a fairly normal schedule, aim to be in bed from 10:00 to 8:00.
- If you are a night owl, get to bed by 11:00.
- If you are an early bird, get to bed by 9:00.
This is only the first step, and the amount of time you need in bed may eventually shrink. If you feel you will go crazy just lying there, put on some soothing music or an audiobook — but do not play with your device. Give this about three weeks to show you what it can do.
Dedicating this much time to sleep matters most at the beginning. As your sleep improves and stabilizes, you will probably only need about 8.5 hours in bed. For a small number of people, staying in bed too long actually makes things worse. It is uncommon, and there is only one way to find out. If after three weeks your sleep truly has not improved, the next step is Sleep Restriction Therapy.
Sleep Restriction Therapy
Sleep Restriction Therapy (SRT) is another well-researched way to reset your circadian rhythm, and it is the next step if the extended schedule did not move the needle.
Start by estimating how many hours you actually slept while lying in bed for 9 to 10 hours. If you truly slept only 6 hours, then you are allowed to be in bed for only 6 hours a night. Aim to go to bed around 10:00 to 11:00. This takes real discipline, because you are not allowed to nap during the day — and you still need to follow all the other sleep hygiene guidelines.
Here is the logic. SRT forces your metabolism’s sleep drive to organize itself around a limited window — give yourself 6 hours and you will move through about four complete 90-minute cycles at best. It is demanding, but if you were already getting six broken hours, consolidating them into solid sleep is a genuine improvement. SRT also spreads your waking drive across roughly 18 hours, weakening it in a way that helps people who struggle to reach the deeper stages of sleep. It is normal to feel tired during the day at first; this usually settles within a couple of weeks.
Do not use caffeine or sugar to stay awake.
Once you have held 6 hours a night for 3 to 4 weeks, add 15 minutes and see whether you sleep all the way through. If you do, add another 15 minutes after four days. If you do not, hold at 6 hours and 15 minutes until your sleep drive adjusts. Over time you should reach at least seven hours, and eventually as close to eight as possible. Some people need a week or two before they can add each increment, so the whole process can take a couple of months of disciplined scheduling.
Throughout, avoid caffeine and sugar. Your metabolism needs zero interference to return to normal. Caffeine feels like energy because it blocks adenosine, the neurotransmitter behind your metabolic sleep drive — it is really just borrowing from tomorrow.
Create a Sleeping Room
It is important to develop an almost therapeutic relationship with your bed and bedroom.
Besides intimacy with your partner and a Sunday-morning cuddle with your kids, the only thing that should happen in your bed is sleep. It is a psychological thing. Many people watch TV, read, do paperwork, surf, and text in bed — and then wonder why the bed no longer signals sleep. If you are recovering from insomnia, treat your bedroom as almost sacred.
- A very quiet room is ideal, but the modern world is full of city noise, heaters, air conditioners, and fifty things that beep in the night. If you cannot control it, use earplugs or noise-cancelling headphones. Many people do well with white noise — a fan, ocean waves, or rainfall. Strangely enough, rain seems to be the best sound to fall asleep to. The least popular tip: keep pets out of the room, since they move and even snore.
- Your bedroom should be as dark as possible — no glow from clocks or devices. Drape a towel over the alarm clock and use electrician’s tape over stray LEDs. Cover your windows with the heaviest, darkest curtains you can find. A complete absence of light for 9 to 10 hours is an important part of resetting your rhythm. A speaking alarm clock, ideally one with gradually increasing volume, is a gentle way to wake.
- Your sleeping chamber should be cooler than usual, because a slight drop in body temperature is needed to enter the deeper stages of sleep. This does not mean shivering — just cool. Aim for 65F or lower at night and 72 to 75F during the day. Your body needs the drop to be noticeable.
- A comfortable bed is essential, and we all quietly adapt to a bed that has stopped serving us. It is worth the time and expense to try a few mattresses and pillows. There is a psychological bonus too: a new bed gives you a fresh environment to associate with sleep, unburdened by the memory of restless nights.
Aromatherapy can help as well. Popular oils for sleep include Roman Chamomile, Lavender, Clary Sage, and Rose. The simplest approach is a small dish beside the bed holding a cotton ball with a few drops of oil; as you settle in, take a few slow breaths from it and let your body soften. If you find it helpful, as many do, a diffuser may be worth the investment.
Regulate Your Light Exposure
Televisions in every room, computers on every desk, and a screen in nearly every hand have caused a genuine explosion in the light entering our eyes each day — and, more importantly, each evening.
Your internal master clock, the suprachiasmatic nucleus, works with your pineal gland to regulate your rhythm and the depth of your sleep. Light at night interferes with the pineal gland’s ability to release melatonin. Ideally your light should dim gradually, with about 40 minutes of minimal light before bed.
- A free app called f.lux gradually strips the blue light from your computer and some smart TVs. You enter your city and it tracks dusk for the whole year. I have used it for years and it makes a real difference — when my screen shifts color, I take it as my cue to turn off unnecessary lights.
- For more stubborn insomnia, switch to red bulbs after dusk, or wear amber glasses for an hour or two before bed. The simplest option is amber safety glasses with side guards from the hardware store.
Dimming the evenings is only half the equation. You also need more light in the morning. In fact, daytime sunlight is the single most important thing you can do to support good melatonin release at night. I recommend at least 20 minutes outside in the morning; if that is impossible, sit by a big window and look out. Skin matters too — you have blue-light receptors on your skin that also help with melatonin and rhythm.
Another option is a light-therapy lamp or visor, often used for Seasonal Affective Disorder (SAD). Choose one rated at least 10,000 lux and use it for 15 minutes each morning between 9:00 and noon, at the same time every day.
Learn to Balance Stress and Relaxation
Cortisol, your primary stress hormone, does not just make your nervous system more nervous — it also competes with serotonin. Since serotonin is the precursor to melatonin, chronic stress is plainly bad for the depth and length of your sleep.
None of us fully controls the stressors in our lives, but reducing the ones we can, and learning to calm the ones we cannot, is essential. Meditation, Qi Gong, Yoga, Breathwork, and even Singing can all help — especially in the hour before bed.
Balance Your Social Life
Of all the influences on your circadian rhythm, the most surprising to most people is social connection. Research suggests that keeping your larger social interactions in the daytime and your evenings calm and intimate helps reset your rhythm. This does not mean you can never go dancing again — it simply means shifting the timing of your social life is another lever for better sleep.
Interestingly, some research suggests that watching shows crowded with characters affects us a bit like being very social, while shows with few faces let us settle more easily. And of course, you will be watching those a couple of hours before bed — right?
Nutrient Density and Sleep
Melatonin is made from serotonin, which is made from tryptophan. Seafood, turkey, almonds, and organ meats like liver and kidney are rich in tryptophan, and they tend to be lower in the competing amino acids that crowd it out during absorption. Eat more of these and you absorb more tryptophan, make more serotonin, and produce more melatonin.
More seafood also brings more long-chain omega-3 fatty acids, especially DHA and EPA, which support your rhythm by improving brain tissue health, lowering inflammation, and building your resilience to stress. Healthy saturated fats — organic butter, coconut oil, eggs with soft yolks — help build your brain and support gut and liver health as well.
And no honest discussion of eating would be complete without this: eat more vegetables. The vitamins, minerals, antioxidants, and fibre help you clear oxidative stress and toxins, support your brain, help keep your pineal gland working well, and, of course, improve your sleep.
A word on the bedtime snack. Some people cannot fall asleep without one, often something starchy like crackers. There is a reason: the starch becomes glucose, blood sugar rises, insulin follows, and higher insulin nudges the brain toward more serotonin — which relaxes you and becomes melatonin. The catch is that starch takes hours to break down while your digestion is sluggish in sleep, which can invite tooth decay and feed Candida and other unwelcome guests. The microbes in your gut love starch, and if they overgrow you may end up sleeping worse — which matters more than it sounds, since a large share of the body’s melatonin is actually produced by a healthy gut. If you must snack, keep it small and pair a little starch with some fat about two hours before bed.
Many traditional cultures simmer milk with nutmeg or cloves — a touch of simple carbohydrate and fat, with spices that help you relax. If you avoid dairy, coconut milk with nutmeg, cloves, cinnamon, and a little honey about 40 minutes before bed is a lovely alternative. Golden Milk is a favourite the world over.
If you tend to wake in the night from hypoglycemia, insulin resistance, or cortisol resistance, some protein with a little fat about 45 minutes before bed often works better. My own favourite is a small serving of leftover protein — it digests slowly into glucose and can help you both fall asleep and stay asleep.
A Word on Alcohol
Millions rely on the sedative feel of alcohol to fall asleep. Unfortunately, alcohol interferes with glycogen release, which is exactly what helps keep you asleep through the night. One of the most common reasons people wake at 3:00 a.m. is hypoglycemia — low blood sugar. When your liver is busy dealing with alcohol, it cannot steady your blood sugar, your brain hits the proverbial red button, and you get restless, broken sleep. Alcohol is very bad for your sleep.
Bringing It Together
I hope this has encouraged you to experiment. Do not try to do everything at once — choose a few guidelines, let them become habits, then add more. This is the winter of the Epi-AIP at work: quiet, patient, restorative. Good sleep supports the tissue repair that is meant to happen every single night, and over time it can genuinely change how you feel.
