Getting adequate sleep is important for health and well-being. Most adults need 7 hours of sleep per night, though needs vary between 5-10 hours per person. Not getting enough sleep can lead to daytime fatigue, trouble concentrating, and increased risk of accidents. Signs that one may not be getting enough sleep include relying on an alarm to wake up, sleeping longer on weekends, feeling tired during the day, and having trouble staying awake in public places. Gradually increasing sleep time can help address a sleep deficiency.
