In a world as busy and on-the-go as the 21st century, taking a nap can be the difference between a successful day and one that falls short. Whether it’s a 20-minute power nap before a night shift or an afternoon nap before the grandkids arrive, a nap can often feel as rejuvenating as an eight-hour sleep. That’s not to say you should choose to nap and make no effort to achieve a good sleep schedule, rather that when life throws up a curveball, a short nap can be the golden ticket. In this article, we’ll look at the benefits of napping, the different types of naps, and whether there’s any negative impact from taking a siesta.
We think it’s safe to say most people love an afternoon nap when they get the chance. However, there’s a range of benefits of napping that you may not have known about. Check out our list below:
By triggering changes in the brain which strengthen the connections between brain cells, sleep is known to help cement events and new learnings in our memory. If you struggle to fit in enough hours at night, it may be wise to consider making a daily nap a part of your routine. When learning new theories or skills, our brains go through three distinct phases: acquisition, consolidation, and recall.
Acquisition is the phase where we learn the new skill. Clearly, this only happens during wakefulness. As does the third stage, which is where we recall it from our memories. But it’s the second stage, consolidation, which has to do with sleep. Research from Harvard shows that sleep has a huge impact on how we consolidate what we’ve learnt. And while different amounts of sleep are right for different types of recall, it’s safe to say that getting an extra sleep cycle in throughout the day is bound to help.
Similar to improved memory, a major benefit of taking a nap is the improved mental alertness you are granted. By strengthening synapses and improving the function of your nervous system, incorporating power naps into your routine can help speed up your response time.
Research suggests that a better approach to sleep can improve the function of the T-Cells in your body. T-Cells play a crucial role in the function of the immune system, searching out infections and breaking them down before they have time to grow.
Sleep is hugely important for keeping your hormones balanced. Without enough sleep, your body can’t regulate your blood sugar. This is because when the body lacks rest, the body finds it difficult to react to the hormone insulin – a key component for regulating for blood sugar. Other hormones that are impacted by sleep or the lack of are those which control growth and development, hunger, cell reparation, and plenty more. All these hormones play a role in how energetic you feel. So, the first step to better energy levels is always to improve your approach to sleep. And if you can’t quite get the recommended eight hours per night, it’s likely a daytime nap could help your body to cope better.
Without enough sleep, our amygdala – the response centre of the brain – becomes overly responsive. In turn, we react to situations more intensely. This causes our blood pressure and heart rate to increase and can, in some instances, result in panic attacks or heightened anxiety.
If you’re a fan of keeping fit or playing regular sports, a benefit of napping is improved performance in the gym or on the field. When you sleep, your body is able to focus on repairing cells and resetting your body to its normal state. If you’re awake too long, the body has to focus on dealing with the day. For example, sleep is shown to play a key role in healing and repairing both your heart and blood vessels – crucial players in any sport!
There are occasions where a nap throughout the day might have a negative impact. This is most noticeable in those who suffer from insomnia and struggle to sleep at night. Certain studies have shown that regular naps of over 60 minutes can increase the likelihood of cardiovascular diseases, metabolic syndrome, and diabetes. This makes it important to regulate your naps to ensure you’re getting the benefits and not doing yourself harm.
Sleep cycles refer to the stages that your body and brain go through while you rest. Until the early 20th century, it was believed that sleep comprised of your body going into one state of rest until you awoke. However, by monitoring the brains activity, scientists discovered that your brain acts differently after amounts of sleep. This plays a huge role on deciding the length of your nap. We won’t go into detail on the different types of sleep cycles here, instead we’ll point out how different lengths of nap have different benefits on the body.
20 mins: A 20 minute nap will result in mostly stage 2 sleep. This improves your mind’s alertness, reduces anxiety and stress, and improves your motor skills.
20 – 45 minutes: Extending your nap to 45 minutes will usually result in you reaching the stage of sleep which includes Rapid Eye Movement (REM). This stage of sleep is known for helping produce necessary proteins in the body, as well as improving creativity and sensory processing.
45 – 90 minutes: A nap that comprises between 45 and 90 minutes will result in you reaching a deep sleep and waking up while your body is halfway through that phase. This will result in you feeling extremely groggy when you wake and will take you a while to come around. If you want a nap longer than 45 minutes, we’d recommend setting your alarm for at least 2 hours after you plan to nod off. This will give you 15 minutes to get to sleep and then beyond the necessary 90 minutes to allow your body to complete a full sleep cycle.
The benefits of napping are almost endless if you ensure you are getting the right amount. Be sure not to nap between 45 minutes and 90 minutes or you may be doing your body more harm than good. However, having a quick power nap, or incorporating long naps into your routine, can help improve brain function, health, and energy levels.
