1)Difficulty falling or staying asleep
The inability to fall asleep or to stay asleep is called insomnia. Insomnia can be due to stress, anxiety or a sign of another underlying problem.
According to the University of California San Francisco (UCSF) health studies, more than 50 percent of the American adults experience insomnia, making it one of the most prevalent sleep disorders in the United States.
If you have trouble falling asleep or staying asleep for more than a few nights, you should consult your doctor immediately.
Snoring is a sign of Obstructive Sleep Apnea (OSA). This is the second most common sleep disorder among Americans, with over 20 million of them affected. According to the National Heart, Lung and Blood Institute (NHLBI), 80% of the people with obstructive sleep apnea do not even realize that they have any sleep disorder.
If you suspect that you have sleep apnea or your partner tells you that you snore, you should get checked up. Sleep apnea is associated with several heart problems including heart failure and should not be assumed.
3)Excessive Daytime Sleepiness(EDS)
If you find yourself falling asleep unawares, or are just feeling an intense urge to keep taking a nap throughout the day, you probably have Narcolepsy. This is a neurological disorder associated with the brains failure to switch between its sleep and wakefulness cycle. Excessive daytime sleepiness can occur even when one has taken enough sleep during the night.
These are intense dream-like visions that can occur at the beginning or the end of your sleep cycle.
According to the US National Library of Medicine, this is one of the early signs of narcolepsy, and it can be quite frightening.
