Sleep deprivation raises the risk of many diseases, and getting fewer than six hours of sleep makes it harder to control appetite and passion. Avoiding screens for an hour before bedtime can improve rest and support recovery from addiction. Morning sunlight helps reset the body’s internal clock, leading to better sleep, stronger mental health, and greater success in overcoming harmful habits. Good sleep hygiene includes keeping the room dark and cool, maintaining consistent sleep and wake times, and keeping the phone in another room at night.
