Is oversleeping bad for you?
How can I tell if I’m a heavy sleeper or actually oversleeping?
Thanks for asking. You're no doubt familiar with what it feels like to be extremely tired after a long sleep. It's a little like a hangover, really. Sluggishness, irritability, perhaps a slight headache too. And there's actually a term for those sensations, sleep drunkenness. According to the Sleep Foundation, the average adult needs between 7 and 9 hours sleep per night, but optimal sleep duration is unique for each of us. It can vary due to factors like genetics, age, and lifestyle habits.
What health risks are linked to regularly sleeping more than 10 hours?
So bear in mind if people call you a heavy sleeper because you sleep 9 hours every night, that doesn't necessarily mean you're oversleeping, it could just be that's the duration you need. How do we distinguish between the two then? Oversleeping disturbs our circadian rhythm, which is regulated by a group of thousands of neurons located in the hypothalamus of the brain. When you keep on sleeping longer than needed, your cells have already begun to send chemical signals to awaken your cognitive and physical functions. That's what leads to daytime drowsiness. When we're experiencing an excessive need for sleep, daytime sleepiness, or chronic exhaustion, we talk about hypersomnia.
How can I reset my sleep routine and avoid oversleeping?
Most often it's caused by a lack of sleep, in which case it's referred to as reactive hypersomnia. It can also be linked to pathologies such as sleep apnea or much more rarely narcolepsy, which is characterized by uncontrollable sleep attacks and extreme drowsiness. It can also be associated with Parkinson's disease and depression. Apart from those specific cases, does oversleeping have any other health consequences? Sleeping for a long time isn't dangerous as such, but if you sleep more than 10 hours per night and still don't feel rested, it's fair to say your sleep is ineffective. You should book an appointment with your GP to discuss it. A 2020 Harvard Medical School study suggested that in the long term, oversleeping can lead to memory problems.
and increase the risk of developing heart problems, type 2 diabetes, and depression. That's also true for people who don't get enough sleep. What can I do to get back into a healthy sleep room? First of all you need to identify what's causing the problem.
What final tips should I follow to maintain a healthy sleep schedule?
Sleep specialists suggest keeping a sleep diary or using an activiter, which is an electronic bracelet that evaluates rest and activity phases. In addition to a clinical and psychological examination, the quantity and quality of sleep can be analysed through a nighttime polysomnography, which studies brain, eye and muscle activity. Doctors recommend establishing a regular bedtime routine to wind down properly. It should involve a calm activity like reading a book and no electronic screams. It's also best to avoid alcohol and heavy meals before going to bed. You should aim to wake up at roughly the same time every day, although you can adjust that by an hour on weekends. Finally, any daytime napping should be limited to 30 minutes max.
