Q&A with Cathryn Coe, naturopathic physician at Marine Drive Naturopathic Clinic
Why do kids need sleep?
The body repairs itself while we sleep. Our immune system is most active during the night, allowing the body to repair. Growth hormone is also secreted at this time.
What's a good amount of sleep for kids?
A good amount of sleep is from nine-12 hours per night. The average is about 10.
How does lack of sleep affect schoolage children?
A poor night's sleep affects brain function. Children and adults can make poor choices if they do not sleep properly including reaching for energy drinks, caffeine and sugar as a means of instant energy. Poor sleep can lead to poor confidence, difficulty focusing, irritability and lack of motivation to engage in sports and after-school activities. Schoolwork and homework can both be difficult if a child is not rested and mistakes are more easily made. Hyperactivity and irritability can also be seen in the classroom with an inability to focus and follow instruction.
How could lack of sleep affect the morning routine?
Children will resist waking up in the morning if they are not rested. Our body produces cortisol in the morning to serve as our natural alarm clock. Chronic poor sleep puts stress on the body and normal hormone production is thrown off. If a child has not had adequate rest they may avoid breakfast, have an upset stomach or anxiety, or they may want a sugary breakfast, which will worsen the fatigue.
What would be some signs that parents could watch for that would indicate a child is not getting enough sleep?
Irritability in the morning, dark circles under the eyes, difficulty focusing at school, resistance going to bed (fears or bad dreams may be keeping them from sleeping properly), trouble staying awake during the day, frequent colds and flus.
How can parents know if they are not getting enough sleep?
Adults will under-perform at work, and may get frequent colds and flus.
Can lack of sleep also affect your physical health?
If so, how? Lack of sleep can be especially harmful for one's health leading to weight gain, diabetes, high blood pressure, heart disease, poor motor skills (driving without paying attention), and it can also accelerate the aging process.
