Sleep better,
simple habits Dr Berg talks about (and how they fit into your routine)
If you’ve watched any of Dr Berg’s videos on sleep, you’ll know one thing comes up again and again: sleep is foundational. When your sleep is off, everything feels harder — mood, energy, cravings, focus.
Below is a plain‑English summary of the main ideas from his sleep videos, plus simple ways to use them in real life in New Zealand and Australia.
1. Kefir and the gut–sleep connection
Dr Berg often highlights kefir as a sleep‑supportive food. Kefir is a fermented milk drink, similar to yogurt but usually richer in microbes.
Key points he makes:
Kefir typically contains many more strains of friendly bacteria than regular yogurt, and often includes friendly yeast as well.
Many of these microbes can survive stomach acid better than those in standard yogurt.
Because the microbes in kefir “eat” some of the lactose, some people with mild lactose sensitivity find kefir easier to tolerate than milk or regular yogurt.
His videos explain that gut microbes are involved in making serotonin and can influence melatonin and tryptophan pathways, which are linked to mood and sleep.
Kefir also provides bioavailable calcium and some B vitamins, including B1 (thiamine), which he ties to stress and nervous‑system support.
How to use this:
If you enjoy dairy, you might try a small serving of plain kefir in the evening as part of your wind‑down routine (for example, half a cup with a few berries). If you’re sensitive to dairy, you may prefer non‑dairy options and focus on other sleep habits below.

2. Cortisol, blood sugar and night‑time waking
A big theme in Dr Berg’s sleep content is cortisol (your stress hormone) and blood sugar balance.
He explains:
Cortisol normally follows a daily rhythm: higher in the morning, lower at night.
Chronic stress, too much caffeine, irregular meals, and frequent snacking — especially late at night — can disturb this rhythm.
When blood sugar drops in the middle of the night, your body may release adrenaline to raise it again, which can wake you up suddenly, often with a racing mind or a “jolt” feeling.
He often recommends lower‑carb eating patterns (such as healthy keto) and intermittent fasting (for example, finishing dinner earlier and avoiding late snacks) to help stabilise blood sugar and reduce night‑time urination and waking.
Simple steps you can try:
Finish your last meal at least 3–5 hours before bed when possible.
Avoid late‑night snacking, especially on refined carbs and sugary foods.
If you do need something small, choose something simple and low‑sugar (for example, a few berries or some celery) rather than biscuits, chips or sweet snacks.
Include enough healthy salt in your daytime meals if you’re on a low‑carb plan, as very low salt can sometimes raise cortisol and affect sleep.
3. REM sleep, deep sleep and your “sleep clock”
Dr Berg also talks about sleep stages:
Deep (non‑REM) sleep happens more in the first half of the night and supports physical repair, detoxification and growth‑hormone release.
REM sleep happens more in the second half and is linked to mental rejuvenation, memory and learning.
Your “sleep clock” in the brain (the suprachiasmatic nucleus) is strongly influenced by light and darkness.
Practical tips from his videos:
Dim the lights in your home in the evening; avoid bright, blue‑heavy light from screens close to bedtime.
Consider warm, dim lighting in the evening (incandescent or warm LEDs, or even a small lamp rather than overhead lights).
Keep your bedroom cool, dark and quiet; many people sleep better with blackout curtains or an eye mask.
Aim for a consistent bedtime window, often around 9:30–10:30 pm for many adults, and try not to push past midnight regularly.
4. Breathing, stress and nutrients that support calm
To help the body shift into sleep mode, Dr Berg often mentions:
Balanced breathing: for example, breathing in for 3–5 seconds and out for the same count, to help signal calm to the nervous system.
Gentle walking most days (even 20–45 minutes) to support stress regulation and cortisol balance.
Nutrients that commonly come up in his sleep discussions:
Vitamin B1 (thiamine) – linked to stress response and nervous‑system function.
Magnesium – often discussed for muscle relaxation and sleep support.
Potassium – described as a “physiological tranquiliser” for nerves and muscles.
Vitamin D – mentioned in relation to insulin sensitivity, immune function and overall health.
These are general nutritional points; the right amounts and forms for you depend on your diet, health status and any medications.
5. Night‑time urination and insulin resistance
In several videos, Dr Berg connects frequent night‑time urination with insulin resistance:
High insulin levels and blood‑sugar issues can make the kidneys filter more, leading to more frequent urination.
Late‑night eating and snacking raise insulin and can worsen this.
He often suggests:
Reducing refined carbs and sugars.
Avoiding snacks after dinner.
Considering a lower‑carb, whole‑food approach and structured meal times.
Ensuring adequate vitamin D and magnesium as part of overall metabolic health.
If you regularly wake multiple times to urinate, it’s worth discussing with your GP, especially if you have risk factors for diabetes or other conditions.
6. Putting it together: a simple evening routine
You don’t need to change everything at once. A realistic Dr Berg‑style evening routine might look like:
Late afternoon / early evening:
Light walk or gentle movement.
Last main meal of the day, lower in refined carbs, with protein, healthy fats and vegetables.
2–3 hours before bed:
Dim the lights, reduce screen time, or use blue‑light filters.
If you like, a small calming drink (for some people, a small amount of kefir or another gentle option).
30–60 minutes before bed:
Quiet activity: reading, stretching, breathing exercises.
Cool, dark bedroom; comfortable temperature and bedding.
In bed:
Simple breathing: inhale 4 seconds, exhale 4 seconds, for a few minutes.
Let go of “trying” to sleep; focus on relaxation instead.
