Yes, there is such a thing as ‘too much sleep’ and you have probably been a victim of it at least once in your life.
Too much sleep can make you tired and lethargic
Ever woken up fatigued? Well, good night’s sleep should leave you rejuvenated and fresh for the day, but that only happens when you sleep to a maximum of eight hours (for adults). Anything above this will be more damaging than good.
The interesting thing is that oversleeping has the same effect on the brain as sleep deprivation. Sleep longer than 7-8 hours, and you may wake up irritable and unable to function as you would normally.
Too much sleep can increase the chances of degenerative diseases
A study found that long sleepers have an increased chance of getting dementia when compared to their light sleeping counterparts. However, it is worth noting that long sleepers not only spend longer than nine hours in bed, but they are also likely to take long naps during the day.
Just enough shut-eye
It is worth noting that the said hours do not apply to everyone. Some people hit the sweet spot at 7 hours, while others need the 8 or nine to rest entirely. Research has shown seven hours to be just fine. As much as several factors may be hindering your ability to sleep well, some elements can be eliminated. Caffeine, a few hours before bedtime, will alter the cycle, as will a long nap during the day. If you have to snooze, (a healthy habit), 30 minutes will not affect your cycle. It would also serve you better to switch off all the lights before you sleep.
