Symptoms of insomnia include difficulty falling and staying asleep at night and feeling tired after a night’s sleep, states Mayo Clinic. An insomnia sufferer takes more than 30 minutes to fall asleep and sleeps for less than six hours for three or more nights a week over a 30-day period.
Additional insomnia symptoms include awakening earlier than needed, daytime fatigue, anxiety, irritability, depression, inattentiveness, clumsiness, tension headaches, brooding over sleep and distress about sleep, explains Mayo Clinic. Consult a doctor to determine the cause of insomnia if symptoms make it hard to function during the day. A doctor may suggest a sleep center to determine if insomnia symptoms indicate a sleep disorder.
Complications of insomnia symptoms include substance abuse, decreased performance at school or on the job, obesity, increased risk for long-term conditions such as heart disease, high blood pressure and diabetes, and slowed reaction time that increases the risk of accidents, according to Mayo Clinic. Risk for insomnia is greater for women, older adults, individuals under stress, those with a mental health disorder and individuals traveling long distances. Stimulants such as caffeine, alcohol and nicotine taken late in the day may intensify insomnia symptoms, and eating too much before sleeping can cause insomnia from heartburn.
