Insomnia
Insomnia is the inability to fall asleep or to maintain a restful sleep throughout the night. People who suffer from insomnia—also called insomniacs—often experience decreased energy, mood swings, and difficulty performing well in school and work activities. This sleep disorder can last for days, weeks, or years. People who suffer from this disorder can experience early insomnia (difficulty falling asleep), middle insomnia (waking up in the middle of the night), or late insomnia (waking up earlier than desired).
There is not one single cause for insomnia. Some insomniacs experience sleep disturbances because of depression, anxiety, or a mental illness. Other times, insomnia is caused by outside influences such as a noisy sleeping environment, a lack of exercise, or too much caffeine ingested during the day. Often a doctor will investigate a patient's lifestyle and sleeping habits as a first step in diagnosing the cause of his or her insomnia.
Insomnia can be treated in many different ways, and most often, lifestyle changes are recommended by doctors. Some of the most commonly suggested home remedies for insomnia are sticking to a sleep schedule, avoiding naps during the day, removing electronic devices and bright lights from the bedroom, and drinking warm milk before attempting sleep. If insomnia persists or begins to negatively impact the sufferer's life, medical attention should be sought.
