For many individuals, an afternoon nap is a guilty pleasure. After a stressful morning at work or even a restless night, a few minutes of sleep can leave you feeling rejuvenated and ready to take on the rest of the day. Research has shown that a short nap can help improve concentration and productivity.
However, not all naps have the same effect on the body. If you find yourself taking long naps every day or needing to nap every afternoon while still waking up feeling tired, experts say your body may be trying to tell you something more than just that you haven't had enough sleep.
Dr Mrinal Sircar, Director, Respiratory & Sleep Medicine, Medanta Noida, explains the importance of knowing how to distinguish a healthy nap from excessive daytime sleepiness.
When is napping actually good for you?
Taking an afternoon nap can be beneficial, particularly if you have had a poor night's sleep, work in shifts or have been engaged in mentally demanding tasks.
Dr Sircar notes that naps lasting 10 to 30 minutes can help improve concentration, productivity and alertness without disrupting your sleep at night.
This is because a brief nap allows your brain to recharge and feel refreshed.
When should frequent naps raise concern?
Experts say the concern begins when naps become a daily necessity rather than an occasional habit.
If you regularly sleep for long periods during the day, your naps interfere with work or daily activities, or you still feel tired despite getting enough sleep at night, it's worth paying attention.
Dr Sircar explains that sleep itself isn't the problem. Instead, excessive daytime sleepiness may be your body's way of indicating that something else needs medical attention.
Health conditions that may be behind excessive daytime sleepiness
According to Dr Sircar, several medical and sleep-related conditions can make people feel unusually sleepy during the day.
Obstructive sleep apnoea
This condition causes repeated pauses in breathing during sleep because the airway becomes blocked. As a result, sleep remains fragmented, leaving people feeling excessively sleepy during the day.
Insomnia
People with insomnia often struggle to fall asleep, stay asleep or wake up much earlier than planned. Poor-quality sleep at night can increase the need for daytime naps.
Restless leg syndrome
This neurological condition causes uncomfortable sensations in the legs and a strong urge to move them, particularly at night. The disrupted sleep can leave individuals feeling fatigued throughout the day.
Other medical conditions
Dr Sircar also notes that conditions such as hypothyroidism, diabetes, heart disease, chronic infections and certain neurological disorders may contribute to excessive daytime sleepiness. Mental health conditions, particularly depression and chronic stress, can also increase fatigue and the desire to nap frequently.
Is there a risk of harm from frequent naps in older adults?
Based on the studies referred to by Dr Sircar, frequent, prolonged and untimely naps in older adults have been associated with poorer health outcomes and a higher risk of mortality. However, this does not necessarily mean that naps themselves are harmful. Persistent daytime sleepiness in older adults should not be overlooked.
When should you see a doctor?
Taking a brief nap that leaves you feeling refreshed is completely normal. However, if your naps become longer, more frequent or start affecting your daily life, it is advisable to consult a sleep medicine specialist to determine the underlying cause.
A short power nap is one of the healthiest ways to recharge during a busy day. However, if you constantly feel drowsy even after getting enough sleep, it is time to pay closer attention.
