We have more health information and tools than any other generation in history. And yet many of us spend the day feeling tired, distracted, and vaguely behind.
LMNT Interview chris williamsonHost of the “Modern Wisdom” podcast for insight. Once a self-described “obsessed productivity bro,” he has spent the past eight years interviewing some of the smartest people on the planet about productivity, health, and self-improvement.
The common thread of their conversation: Meaningful health changes often come from reducing friction around simple habits, not elaborate routines.
key points:
- Small, repetitive behaviors are more likely to stick and produce lasting health improvements than complex routines.
- When a behavior fits naturally into your day, you’re more likely to keep it up.
- Basics like sleep, light exposure, hydration, and attention management have a much bigger impact than effort.
Why do simple habits stick?
According to him, simple habits are more likely to stick than habits that require more planning and brain power a meta-analysis.
This is definitely true when it comes to health:
- One 2025 meta-analysis found that sedentary adults who started the day with vigorous movements such as climbing stairs or short cycling intervals saw improvements in cardiovascular fitness and lower LDL (‘bad’) cholesterol over several weeks to months.
- A randomized trial Found that adults with metabolic syndrome who implemented small, repeatable habits — eating vegetables at meals, taking brisk walks, and pausing before reacting to stress or eating — were significantly more likely to achieve metabolic syndrome remission after two years than those who only received health education and an activity monitor.
The mechanism appears to be automaticity and simplicity: habits that do not require willpower are easier to repeat, and behaviors that are repeated frequently are more likely to cause changes in metabolism, sleep, and energy levels over time.
It’s tempting to dismiss obvious advice like “eat more vegetables” as if it’s too easy to make a big change. But the basics keep coming back to life again and again for one reason: They work.
Here are five high-impact habits you may have heard about, but probably don’t, that Williamson swears by.
Sleep with your phone outside your bedroom
“This is the cheapest, completely free lifestyle intervention that will immediately improve your quality of life,” says Williamson.
Most people still sleep with their phone within arm’s reach: 83% of US adults surveyed by YouGov in May 2025 Keep your smartphone in the bedroomAnd 43% always or often check them within 10 minutes of going to sleep.
Have to use phone within 30 minutes of sleeping is connected to Late bedtime, less sleep, and daytime drowsiness. Screen light—especially bright or long exposures—can suppress melatoninThe hormone that signals it’s time to sleep.
Do you need help getting your phone out of your bedroom? “Get a Screen Time app,” says Williamson. “From 7 a.m. to 8 p.m. you can use your phone, and then from 8 p.m. to 7 a.m., you can’t.”
Think of it as intermittent fasting for your phone use.
Start the day with sun and movement
“My morning routine is to get up and go for a walk. I get fifteen minutes of sunlight in my eyes,” Williamson says.
This strategy is specifically shared by the experts they interviewed Neuroscientist Dr. Andrew HubermanWhich suggests taking sunlight for 5-10 minutes in the morning on sunny days and 15-20 minutes on cloudy days.
Research Exposure to sunlight before 10 a.m. improves sleep quality and leads to more restful sleep the next night.
Morning light also:
- helps regulate your cortisol awakening response – Apart from stress-induced cortisol spikes – which impact your memory and emotional regulation abilities for the day.
- anchor circadian rhythm Internal clocks that regulate sleepiness and alertness – by suppressing melatonin.
If you take a walk drenched in sunlight, you may also get caught up in some of the hustle and bustle. Even if you don’t get recommended 7,000 stepsYou’ve already done something that moves your physiology in the right direction.
Use hydration as a force multiplier
“If I’m not hydrated enough, my brain doesn’t function well,” says Williamson.
stay hydrated Important for energy, mental clarity and mood support. your mind moves water and electrolytes.
When you’re dehydrated, your hypothalamus increases production of the hormone vasopressin, a hormone that helps regulate the body’s water balance by signaling the kidneys to conserve water.
That may be linked to an increase in stress hormones such as signals cortisol. Yours Brain The body shrinks measurably (but temporarily) to maintain fluid balance.
neural activity Becomes less efficient, meaning your brain has to work harder to maintain the same level of performance.
Even mild dehydration can impair your ability to concentrate, Research Gives suggestions. This is a problem when you’re trying to form new habits because executive functionsIncluding attention, memory, and suppressing inhibitions, drivers of healthy behavior.
According to one review, exercise appears to be significantly more difficult due to mild to moderate dehydration with a loss of 1.5% to 3% of body mass. Journal of Exercise Science and Fitness.
Dehydration increases the rate of perceived exertion (RPE), making a workout feel more difficult, resulting in scrap quantity.
In some cases, water alone does not always solve the problem. “Proper hydration isn’t just about having enough fluid in your body,” says Williamson, a drinker. electrolyte water In the morning and during podcast recording.
“It contains electrolytes that allow your body to actually use the water you consume.”
Schedule a full day phone-free vacation
When your phone is always nearby, your nervous system rarely gets rest.
Research Suggests that constant notifications keep us in a state of anticipation of the next dopamine hit from a text, comment or headline.
and only phone presence We may be distracted from the benefits of in-person social interactions.
Research It also shows that frequent phone use is associated with higher rates of depression, stress, anxiety and sleep problems.
This becomes a vicious cycle – problematic phone use contributes to mental health problems, and then people become more addicted to their phones as they use it looking for a quick mood boost.
Time spent on smartphones can be reduced reduce stressstabilize your mood, and boost energyNot to mention reducing the mental fatigue that comes from having too many things running through your mind.
Eat dinner earlier for better sleep
“Eating a little before bed definitely helps me sleep better, so I’ve been making an effort to eat dinner earlier,” says Williamson.
If you’re working late or juggling kids with activities, dinner may be later than you’d like. But eating too close to bedtime Some of the ways sleep quality can be reduced are:
- circadian disruption: : Meal time serves as a signal for us biological clocks Which controls sleep. We have to eat during the day and fast at night.
- Increase in blood sugar: You can avoid eating before sleeping increased blood sugar When your body is preparing to rest.
- Hormone changes: eat late too hormone nudge Like cortisol and melatonin out of their normal rhythm.
- Changes in body temperature: Eating food two to three hours before sleeping can increase the body temperature slightly which can disturb sleep. preliminary research Gives suggestions.
Over time, this may increase some studies It has been suggested that eating late is associated with markers of inflammation and mood disturbances.
The time of meal should be such that it suits your sleep. This could mean a light, pre-bedtime snack, or it could mean a good three to four hours between dinner and bedtime.
This is one of those places where you have to find what works for you – and the quality of your sleep is feedback.
takeaway
These strategies won’t win awards for innovation. They work because they align with basic physiology and remove unnecessary friction. In a culture obsessed with increasingly complex health tips, there is real power in simplicity.
When sleep, light, hydration, meal timing, and meditation are incorporated, everything built on top of them becomes easier to maintain.
Frequently Asked Questions
Question: Does eating food late at night affect sleep?
it. A Study Among 793 young adults, it was found that eating within three hours of bedtime was associated with more waking at night.
a larger population based study Even stronger effects were found – eating within an hour of bedtime more than doubled the chances of waking up after sleep onset.
A good starting point: Aim for three hours between your last meal and bed, then adjust depending on how you sleep. It may take a little experimentation to find what works for you.
Question: Can dehydration cause brain fog?
Yes, and it doesn’t take much. A meta-analysis 33 studies found that dehydration impairs attention, executive function, and motor coordination.
the smaller the fluid loss 1%-2% of body weight Can impair focus and working memory, and contribute to anxiety and stress.
Q: How much time should I spend in the morning sun?
Aim for 10 to 30 minutes of outdoor light within the first few hours of waking up. A 2025 study More than 1,700 adults found that exposure to morning sunlight every 30 minutes improved sleep quality.
Mechanism: Morning light sets your circadian clock, causing the countdown to melatonin release about 12-16 hours later.
Earlier light exposure means earlier, more predictable melatonin onset – and better sleep.
