A few small choices early in the day may protect cognitive health as you age.

Key Points

• Start your day with morning light to support sleep, mood and long-term brain health.
• Drink water first thing to stay hydrated and support focus, memory and blood flow.
• Move your body early to boost energy, blood flow and cognitive health over time.

Dementia risk is influenced by many factors, including age, genetics and family history. Still, research suggests that everyday habits can support long-term cognitive health. The good news is that those habits don’t have to be complicated. Small, realistic choices before 10 a.m. may help support sleep, hydration, blood flow, mood and focus—all important for long-term cognitive health. Here’s what experts recommend doing in the morning to help lower dementia risk.

1. Get Morning Light Soon After Waking

One of the most consistent recommendations from brain experts is also one of the simplest—get outside early. Morning light is one of the strongest signals for your circadian rhythm, the internal clock that helps regulate your sleep-wake cycle.

“Early daylight exposure activates our retino-hypothalamic centers responsible for controlling our circadian rhythm, which plays a central role in preserving overall sleep quality, improving cognitive performance and maintaining long-term brain health,” says Jon Stewart Hao Dy, MDa board-certified neurologist.

In simpler terms, morning daylight tells your brain the day has started. That cue helps your body feel alert during the day and wind down at bedtime. And sleep is one of the ways your brain supports memory, learning and overnight cleanup processes that help clear metabolic waste.

Dy recommends spending 10 to 20 minutes outdoors shortly after waking, even if you’re not exercising. Sip your coffee outside, take your dog for a quick walk around the block, or step into the sunlight while checking your calendar for the day.

2. Drink a Glass of Water

After several hours without fluids overnight, many people wake up a little dehydrated, so starting your day with a glass of water is a simple habit worth building. “The human brain is made up of approximately 75% water, so if the water content of the brain decreases due to dehydration, cognitive processing speed slows considerably and working memory decreases significantly,” says Wilfred G. van Gorp, Ph.D., ABPPa clinical neuropsychologist.

In a 2025 cohort study of cognitively healthy older adults, researchers found that lower daily fluid intake was associated with higher levels or faster increases in amyloid-beta deposition, a hallmark brain change linked to Alzheimer’s disease, the most common type of dementia. Drinking a glass of water first thing can help you start the day better hydrated, which may support blood flow, focus and working memory while making it easier to meet your fluid needs throughout the day.

Keep a glass by your bed or pair your new water habit with something you already do, like taking morning medications or making breakfast.

3. Break Up Indoor Inactivity

If you start your morning sitting indoors under dim light—checking email, scrolling on your phone or jumping straight into work—it may be worth building in a few movement breaks. You don’t need a full workout before 10 a.m., but getting your body moving early may help support blood flow, energy and mental clarity.

“Physical activity produces brain-derived neurotrophic factor (BDNF), a protein that is essential for neuronal repair and growth,” says van Gorp. Research suggests that exercise can increase BDNF levels, which is one way regular movement may help support memory, attention and cognitive health over time.

Getting up and moving—especially outside—can also help shift your body into daytime mode. “I always recommend patients avoid starting the day with prolonged indoor inactivity and screen exposure in low light, as these little habits can delay our circadian rhythm alignment and negatively affect cognitive performance during the day and sleep quality later in the day,” says Dy.

It can be as simple as a 5- to 10-minute walk outside, stretching while your coffee brews or doing a few chores before sitting down to work. The goal is to break up long stretches of sitting and give your brain and body a clear wake-up cue.

4. Plan 3 Things You’ll Look Forward To

A little positive anticipation may be one simple way to begin the day with your brain health in mind. “As you get your morning started, plan three things you will do over the course of the day that will bring you joy and satisfaction. Positive emotion is good for the brain and body,” says Allison B. Reiss, M.D.a member of the Medical, Scientific & Memory Screening Advisory Board for the Alzheimer’s Foundation of America.

Research suggests psychological well-being may be linked to long-term cognitive health. In a recent study, positive affect, life satisfaction and purpose in life were associated with lower dementia risk, with sense of purpose showing the strongest association.

This habit may sound small, but it gives your brain a little mental exercise. Planning requires decision-making, memory and flexible thinking, while positive anticipation may help lower stress. Over time, stress and low mood may take a toll on the brain, and research has linked both to cognitive decline.

Some of the things you plan may involve activities that are known to reduce dementia risk—like social engagement, physical exercise, eating a healthy meal or being out in sunlight. “This will magnify the effect of making your list,” Reiss adds.

Keep a notebook by your bed or write your three things in your phone before the day gets busy. As Reiss suggests, check them off at the end of the day so you can see the small moments of joy and satisfaction you’re building into your life.

Other Habits to Lower Risk for Dementia

• Follow a brain-healthy eating pattern. Diets like the MIND and Mediterranean diets emphasize vegetables, berries, beans, whole grains, fish, nuts and olive oil, while limiting foods high in saturated fat and added sugar.
• Prioritize quality sleep. Poor sleep has been linked to cognitive decline, so maintaining a consistent sleep schedule and addressing sleep issues, such as snoring or sleep apnea, can be important.
• Stay socially and mentally engaged. Spending time with others, learning new skills, reading or doing hobbies may help build cognitive reserve and support emotional well-being.

Our Expert Take

Some dementia risk factors—like age, genetics and family history—are outside your control. But the choices you repeat each day still matter. You don’t need an elaborate morning routine to support your brain health, either. Experts recommend starting small. Over time, these simple practices can support the systems your brain relies on, including sleep, hydration, blood flow, mood and stress regulation.
