Why Sleep Matters for Your Health

Most adults function best with roughly seven to nine hours of sleep. Quality and regularity matter as much as total hours.

What happens during sleep

Sleep supports tissue repair, immune function, memory consolidation and the hormones that regulate hunger and stress.

Signs your sleep may need attention

• Taking a long time to fall asleep most nights
• Waking often and struggling to settle again
• Feeling unrefreshed despite enough time in bed
• Relying on caffeine to get through the day

Practical steps

1. Keep wake-up time steady, including weekends
2. Get daylight early in the day
3. Keep the bedroom cool, dark and quiet
4. Move screens and work out of the bed
5. Limit caffeine after early afternoon
