Why sleep matters

Good sleep is important for emotional well-being. Regular sleep habits may help support mental health, but sleep habits alone do not treat a mental-health condition. Severe or distressing symptoms that last 2 weeks or more warrant professional help.

Steps that may help

• Keep a regular wake time, including on most days off.
• Make the bedroom dark, quiet, and comfortable.
• Use the hour before bed for calm activities instead of bright screens.
• Limit caffeine late in the day and avoid alcohol as a sleep aid.

The Centers for Disease Control and Prevention explains that adults generally need at least seven hours of sleep, though needs vary. Read the CDC sleep guidance.

When to ask for help

Talk with a clinician if sleep problems continue or make daytime life difficult. Cognitive behavioral therapy for insomnia is a structured 6- to 8-week treatment usually recommended first for long-term insomnia. Feeling sleepy or tired despite enough sleep can warrant medical evaluation.

Talk with your healthcare provider before using melatonin or another dietary supplement for sleep because supplements may have health risks.

Bottom line

Steady sleep habits may support well-being, but they are not a cure-all. Seek individualized help when sleep or mental-health symptoms persist.

A realistic routine

Choose one small change first, such as a steady wake time. Give it time before adding more changes. A routine that fits your work, family, and health needs is more useful than a strict plan you cannot keep.

Sleep advice should also account for medicines, pain, breathing problems, and shift work. A clinician can look for causes that a sleep-hygiene list cannot identify.
