Learn how a NASA nap can boost your alertness and job performance through a specific, short-duration sleep strategy.

What Is a NASA Nap?

A NASA nap is a brief period of sleep, often called a power nap, used to optimize work performance and mental clarity. This approach gained prominence after the National Aeronautics and Space Administration began researching how short rests could keep pilots alert during their shifts starting in 1995.

A NASA nap study found that pilots who slept for 26 minutes saw a 34% improvement in job performance and a 54% increase in alertness compared to those who stayed awake. These pilots also reported feeling significantly less sleepy toward the end of their flights.

Benefits of Short Power Naps

A brief rest of 20 to 30 minutes can enhance mood, concentration, and alertness. These short intervals help reduce sleepiness without causing the heavy grogginess often felt after longer rests.

Other advantages associated with brief naps include:

Lower blood pressure and improved heart health.
Faster reaction times.
Better focus and increased creativity.
Enhanced memory.

How to Power Nap Like an Astronaut

To maximize the effects of this strategy and avoid sleep inertia—the sluggish feeling that follows deep sleep—follow these steps:

Time it correctly: Aim for a total of 32 minutes, allowing 6 minutes to fall asleep and 26 minutes of actual rest. Keep total sleep under 30 minutes to avoid grogginess.
Use caffeine: Drinking caffeine right before lying down may provide a stronger energy boost than napping alone.
Optimize your environment: Find a quiet, dark space with a comfortable temperature. If you are at work, use an eye mask or earplugs to block light and noise.

When to See a Doctor

While short naps can help with temporary tiredness, consult a healthcare provider if you experience:

Excessive daytime sleepiness that persists despite adequate nighttime rest.
