What are the benefits of a short, midday nap?

Scientific research has shown that daytime sleep, or “power naps,” can enhance both cognitive and emotional health. Many sleep experts suggest that an ideal nap should last for about 10 minutes.

Recognizing the benefits, Real Madrid has incorporated siesta time into their team’s schedule to boost performance and speed up recovery. Similarly, companies like Google and Nike have introduced sleep pods or “quiet rooms” for their employees to rest and meditate when they’re feeling drained.

The Benefits of a Power Nap

Dr. Guy Meadows, a sleep psychologist and the founder of The Sleep School, lists several benefits of taking a power nap:

“A brief nap allows your body and brain to enter a light sleep state, which can help replenish energy, enhance memory, reduce stress, and support cardiovascular and cognitive health. Short naps can even lower blood pressure and heart rate variability. They also improve memory association, emotional self-control, and problem-solving skills.”

Meadows also notes that napping can indirectly aid in weight management by curbing fatigue-induced overeating.

A study conducted by University College London (UCL) on participants aged between 40 and 69 found that those who napped regularly had larger brain volumes. This suggests that frequent, short naps can contribute to long-term brain health by slowing age-related brain shrinkage and reducing the risk of dementia.

Napping can also stimulate creativity. The brain requires periods of rest to enhance its problem-solving and idea-generating capabilities. Moreover, when we’re sleep-deprived, our cortisol (stress hormone) levels increase. A short nap, even just a few hours long, can help alleviate feelings of excessive stress.

What is the Ideal Nap Duration?

Experts generally recommend a nap duration of 10 to 20 minutes. Napping for longer periods can actually have the reverse effect.

Dr. Maja Schaedel, co-founder of The Good Sleep Clinic, elaborates:

“Even a 15-minute nap can trigger restorative processes in the body – tissues are repaired, muscles are built, and the immune system is strengthened. Sleep is particularly beneficial for learning new skills, and it’s absolutely crucial for infants.”

Are There Any Downsides to Daytime Napping?

Yes, but only if the naps are too long or too frequent.

Dr. David Lee, director at Sleep Unlimited and author of Teaching the World to Sleep, cautions:

“Daytime sleep isn’t essential for someone who gets adequate, quality sleep at night. If a person tells me they nap a lot during the day, I would want to examine their overall sleep cycle.” The issue lies in the fact that daytime napping can decrease your “sleep pressure” – the need for sleep that builds up the longer you stay awake. This need is primarily controlled by adenosine, a substance that accumulates in the brain. As a result, you may find it harder to fall asleep at night or maintain a continuous sleep cycle.”

This means that fatigue is a crucial element of our circadian rhythm. Ideally, we want to allow our “sleep pressure” to build up throughout the day to the point where sleep is irresistible by nightfall.

As Dr. Schaedel explains, “Daytime sleep can disrupt nighttime rest, creating a vicious cycle: the more frequently you wake up at night, the more tired you’ll feel the next day, and the more you’ll feel compelled to nap.”

Is napping suitable for everyone?

Dr. Lee suggests that certain groups can significantly benefit from daytime napping, including:

• The elderly
• People with brain injuries
• Stroke survivors
• Individuals with dementia

However, it’s important to note that naps should ideally not exceed 2 hours in length.

Should we sleep more as we age?

Research indicates that approximately 25% of individuals over the age of 60 take daytime naps. While these naps may enhance alertness, frequent napping could be a sign of underlying health issues.

Final thoughts: If you enjoy a daytime nap and feel rejuvenated afterwards, feel free to incorporate it into your routine.

If you find yourself needing a nap due to extreme exhaustion and an inability to function without it, it might be wise to schedule a general health checkup.
