11. Lower cognitive skills
> Possible sleeping disorder(s): Circadian rhythm disorder

A good night’s sleep is crucial for mental stimulation and cognitive functions. Impaired performance at work or lower cognitive skills for a prolonged time could be a sign of a sleep problem like circadian rhythm disorder, which affects the brain’s ability to communicate to the rest of the body that it is time to rest.

12. Night sweats
> Possible sleeping disorder(s): Obstructive sleep apnea

While most of us occasionally sweat at night if the room is too hot or we wear too many clothes, night sweats refer to repeated episodes of severe hot flashes that occur during sleep and cause excessive sweating that can drench sleepwear and sheets. Night sweats may be caused by several underlying conditions, including obstructive sleep apnea. The muscles in the chest and throat relax during sleep, causing obstructions that block airways, and causing night sweats in some people.

13. Not being able to exercise as much as usual
> Possible sleeping disorder(s): Central sleep apnea

Those who find they are unable to exercise for as long as they used to or with the same intensity may have central sleep apnea. This type of sleep apnea causes people to briefly stop breathing during the night because the brain does not tell the lungs to inhale.

15. Sleep paralysis
> Possible sleeping disorder(s): Narcolepsy

Sleep paralysis is a disconcerting phenomenon in which someone is unable to move or speak for at most a few minutes after waking up or just before falling asleep. This occurs when the body does not move through sleep stages properly. Though it is usually not a sign of any major issues, sleep paralysis is sometimes associated with narcolepsy, a disorder in which the brain struggles to regulate sleep.
