Stress, Blood Pressure and Blood Sugar: Breaking the Cycle
Updated July 14, 2026 · 5 min read
Short bursts of stress are normal. But long-term stress can raise blood pressure and blood sugar and make healthy habits harder to keep.
What stress does in the body
Stress hormones like adrenaline and cortisol raise heart rate, tighten blood vessels and release stored glucose for energy. When stress is constant, these effects can contribute to higher blood pressure and glucose. Stress also affects sleep, eating and motivation to exercise.
Practical techniques
- Slow breathing: inhale for 4 seconds, exhale for 6, for five minutes.
- Regular physical activity, which is one of the best stress relievers.
- Short breaks outdoors during the day.
- Talking to friends, family or a counsellor.
- Limiting news and social media if they increase anxiety.
- Writing down worries and one next step for each.
Watch for burnout and depression
Living with a long-term condition like diabetes can be draining — 'diabetes distress' is common. If you feel persistently low, hopeless or overwhelmed for more than two weeks, speak to a healthcare professional. If you have thoughts of harming yourself, contact emergency services or a crisis line right away.
