Researchers have identified a long-acting way to improve cognitive function without relying on caffeine. A recent study found that moderate-to-vigorous physical activity, such as brisk walking or cycling, improves memory and brain power, particularly in episodic and working memory.
The study involved 76 adults aged 50-83 who wore sleep and physical activity trackers for eight days and underwent daily cognitive tests. The results showed that about 30 minutes of moderate-to-vigorous physical activity improved episodic and working memory, while an extra 30 minutes of sitting was linked to a small decline in working memory.
The researchers found that the benefits of exercise may persist for up to 24 hours after the initial physical activity. Exercise signals the body to produce more energy, releasing endorphins and norepinephrine, which boost alertness and make individuals feel more awake.
Unlike caffeine, which can cause anxiety, increased heart rate, and higher blood pressure, exercise has been shown to improve mood and reduce anxiety. The study’s findings suggest that cutting back on coffee and other caffeinated beverages may be beneficial for overall health, as excessive caffeine consumption can lead to withdrawal symptoms such as nausea, fatigue, and low energy.
In contrast, moderate exercise has proven effective at beating those withdrawal symptoms. By incorporating 30 minutes of moderate-to-vigorous physical activity into your daily routine, you can give your brain a 24-hour cognitive boost without relying on stimulants.
