Why sleep is medicine
During deep sleep your body repairs tissue, consolidates memory and regulates the hormones that control appetite and stress. Adults consistently sleeping under 6 hours have measurably higher risks of infections, high BP, diabetes and weight gain. Aim for 7–8 hours at a consistent time.
Habits for deeper sleep
- Fix a wake-up time first — a steady morning anchors the whole cycle.
- Screens off (or at least dimmed and boring) 30–60 minutes before bed.
- No tea/coffee after evening; keep dinner light and 2–3 hours before sleeping.
- Keep the room dark, quiet and cool; use the bed for sleep, not scrolling.
Managing everyday stress
- Slow breathing (4 counts in, 6 counts out, for 5 minutes) calms the nervous system measurably.
- A daily 20–30 minute walk is a proven mood and BP intervention.
- Name it to tame it: writing worries down or talking to someone reduces their weight.
- Persistent low mood, anxiety, or hopelessness for weeks deserves professional help — mental health is health, and treatment works.
The immunity connection
Chronic stress keeps cortisol high, which suppresses immune response — one reason run-down, stressed people fall sick more often. Consistent sleep, daily movement, balanced meals and time with people you trust do more for immunity than most 'boosters' sold in the market.
