Normal sleep patterns refer to a regular and consistent schedule for going to bed and waking up. It means getting enough quality sleep each night, which is typically 7-9 hours, depending on age and individual needs. This routine allows our bodies to function properly by allowing time for both deep restorative sleep (stage 3) as well as lighter stages of sleep throughout the night. Disruptions in normal sleep patterns can lead to a variety of health issues such as difficulty concentrating or irritability, so maintaining consistent bed and wake times is important for overall physical and mental well-being.
