How to Get More Deep Sleep Naturally

How to get more deep sleep naturally may be simpler than you think – and it starts long before your head hits the pillow. More than a third of Americans are chronically sleep-deprived, and the consequences go far beyond feeling groggy. One study found that just one week of six-hour nights caused over 700 genes to change their activity – a striking sign of how systemic sleep is to every aspect of health: metabolic, heart, brain, immune, and mental.

The good news is that science-backed sleep hygiene habits combined with whole-food, plant-based nutrition can meaningfully improve both sleep quality and duration – with benefits ranging from feeling your best each morning to lower long-term risks of stroke and dementia.

Sleep hygiene basics: the foundation

Most sleep improvements start with your environment and evening routine. These are largely one-time, low-cost investments that pay health dividends every night:

• Darkness: make your bedroom as dark as possible with blackout curtains or a comfortable eye mask
• Temperature: keep your room cool, ideally 68–72°F
• Quiet: earplugs or white noise can make a meaningful difference
• Comfort: choose pillows suited to your sleep position – long body pillows work especially well for side sleepers
• Wind-down routine: avoid bright or blue light in the hour before bed (most devices can shift to warmer colors after sunset; red bulbs are another option), and avoid caffeine, nicotine, alcohol, and stress-raising content like news
• Warm shower or footbath: solid evidence supports taking a warm shower before bed to fall asleep faster and sleep more deeply – wearing socks to bed can also help mildly

How to get more deep sleep with a plant-based diet 

Beyond sleep hygiene, emerging research shows that whole-food, plant-based eating naturally supports deeper, more restorative sleep – calming your nervous system, fueling melatonin production, and helping your gut microbiome sync with your body’s circadian rhythm.

In his bestselling book How Not to Age, Michael Greger MD highlights that plant-based eaters consistently report significantly better sleep quality. Two mechanisms explain much of this:

What animal foods do to your sleep Higher levels of methionine in animal products appear to compete with tryptophan – the precursor to both melatonin and serotonin – for entry into the brain. Meat consumption has also been linked to roughly double the odds of snoring, which disrupts sleep architecture and reduces time in deep sleep stages.

What plant foods do for your sleep Whole plant foods deliver nutrients your body uses directly to improve sleep quality – including melatonin, magnesium, and potassium – along with abundant fiber that feeds your gut microbiome. In return, your gut produces roughly 90% of your body’s serotonin, plus anti-inflammatory molecules that make it easier to stay asleep without aches and pain. It’s no surprise that a majority of people report better sleep after transitioning to a plant-based diet.

The best foods for deep sleep

Certain plant foods have particularly strong evidence for improving sleep quality:

• Beans, legumes, whole grains, and sweet potatoes – complex carbohydrates and fiber that trigger satiety signals correctly and support gut health overnight
• Berries and leafy greens – high-density phytonutrients and antioxidants support cellular repair during sleep; romaine lettuce in particular has documented sleep-promoting properties
• Tart cherries – one of the most studied foods for sleep improvement, linked to meaningful increases in melatonin levels
• Kiwi – a standout finding: eating two kiwis an hour before bedtime was shown in research to add approximately one full hour of sleep

The bottom line on how to get more deep sleep

Getting more deep sleep doesn’t require a pill, a gadget, or an expensive mattress. The most evidence-based path combines a dark, cool, quiet sleep environment with a consistent wind-down routine – and a diet built around whole plants that naturally calm your nervous system, fuel melatonin production, and feed the gut microbiome that keeps your body’s internal clock running smoothly.

Plants don’t just fuel your days – they restore your nights.

Frequently Asked Questions About How to Get More Deep Sleep

How can I get more deep sleep naturally? The most evidence-based approach combines sleep hygiene fundamentals – a dark, cool, quiet bedroom and a consistent wind-down routine – with a diet rich in whole plant foods. Plants supply melatonin, magnesium, potassium, and fiber that directly support deeper, more restorative sleep stages.

What foods help you get more deep sleep? The most studied sleep-supporting foods are tart cherries, kiwi, leafy greens, beans, legumes, whole grains, sweet potatoes, and berries. Two kiwis eaten an hour before bed has been shown in research to add approximately one full hour of sleep. Tart cherries are among the richest dietary sources of melatonin.

Does a plant-based diet improve sleep? Yes – research highlighted by Michael Greger MD in How Not to Age shows that plant-based eaters consistently report better sleep quality. Whole plants supply sleep-supporting nutrients directly while also feeding the gut microbiome, which produces roughly 90% of the body’s serotonin and anti-inflammatory compounds that reduce nighttime discomfort.

Does meat affect sleep quality? Research suggests it can negatively impact sleep in two ways. Higher methionine levels in animal products compete with tryptophan – the precursor to melatonin and serotonin – for absorption into the brain. Meat consumption is also linked to roughly double the odds of snoring, which disrupts sleep architecture and reduces time in deep sleep stages.

What temperature should your bedroom be for deep sleep? Research supports a bedroom temperature of approximately 68–72°F as optimal for sleep. A cooler environment helps trigger the natural drop in core body temperature your body uses as a signal to enter deeper sleep stages.

Does a warm shower before bed actually help sleep? Yes – this is one of the better-supported sleep hygiene recommendations. A warm shower or footbath before bed helps accelerate the drop in core body temperature that signals your brain to initiate sleep, resulting in faster sleep onset and deeper sleep stages.

How much sleep do most Americans actually get? More than a third of Americans are chronically sleep-deprived. Research has found that just one week of six-hour nights caused over 700 genes to change their expression patterns – underscoring how deeply sleep deprivation affects overall health beyond just feeling tired.
