Napping, stress relief and immune system health
The results? When the men were not allowed to nap their levels of hormones and neurotransmitters involved in the body’s fight-or-flight response to stress were higher than when they had a nap.
They also found that levels of an antiviral protein dropped when the men didn’t nap, suggesting that a nap could be good for immune system health too.
“Napping may offer a way to counter the damaging effects of sleep restriction by helping the immune and neuroendocrine systems to recover,” said one study author Brice Faraut, PhD.
“The findings support the development of practical strategies for addressing chronically sleep-deprived populations, such as night and shift workers.”
Why you should take a nap at work
In more good news for those partial to a nap, the science suggests that it may even help you perform better at work.
A German study found that napping for about an hour produces a
five-fold improvement in information retrieval from memory.
And a 2017
Sleep Health Foundation report found that Australian's lack of sleep substantially reduces workplace productivity of $17.9 billion dollars.
Dr Fiona Kerr, a neural and systems complexity specialist at the University of Adelaide told
SBS Insight that napping:
- Increases alertness and creativity
- Increases motor performance
- Boosts stamina
- Lifts your mood
- Improves problem-solving
- Improves cognitive function
How to take a a good nap
- Make it part of your routine - if you nap regularly try to take a nap at the same time each day
- Pick the right environment - nap in a quiet dark place with a comfortable temperature
- Keep it short - a good length of time for a nap is 15 30 minutes. Any longer and you're likely to feel more tired than before you took a nap, or make it harder to sleep well at night
