You often have difficulty falling asleep, have light sleep, or sometimes have light sleep or wake up in the middle of the night for no apparent reason. All of these conditions can affect the quality of sleep, cause many health problems, and affect daily work.

Waking up in the middle of the night can be very frustrating, especially when it happens frequently. Getting enough sleep is very important for your health. When your sleep is disturbed, it takes your body a while to get back into deep sleep, which can leave you feeling less alert the next day.
