VIDEO LESSON
What happens
Sleep restriction increases hunger hormones and lowers insulin sensitivity within days. Shift work and late eating disrupt the body clock that coordinates metabolism.
What helps
• 7 or more hours of sleep for most adults
• A consistent wake time and morning light
• Earlier, lighter evening meals
• Screening for sleep apnea if you snore or feel sleepy
Good to know
CBT for insomnia is the first-line treatment for chronic insomnia and works better long term than sleeping pills.
