Understanding stress: What it does to your body and what you can do about it

Stress is something most of us experience, but when it builds up or sticks around too long, it can start to take a toll on both our body and mind.

According to the Mental Health Foundation, 74% of UK adults have felt so stressed at some point over the past year they felt overwhelmed or unable to cope. And while stress can sometimes help us stay focused or meet a deadline, chronic stress is a different story.

Common symptoms and warning signs

Stress doesn’t always look the same from one person to the next. You might notice:

  • Trouble sleeping or waking up tired
  • Muscle tension (especially in your jaw, neck, or shoulders)
  • Difficulty concentrating or racing thoughts
  • Changes in appetite
  • Feeling irritable, anxious, or withdrawn
  • Headaches, stomach issues or frequent illness

Over time, prolonged stress can increase your risk of heart disease, depression, and burnout. The NHS highlights that stress affects almost every system in your body, from your immune function to digestion and memory.

What can help?

The good news: there are small, manageable steps you can take to reduce stress and protect your wellbeing. Here’s where to start:

Get moving – Even a brisk 10-minute walk can reduce tension and boost your mood.
Prioritise sleep – Stick to a routine and wind down before bed (without screens if you can).
Talk to someone – Whether it’s a friend, colleague or therapist – speaking up helps.
Breathe – Try deep breathing exercises to calm your nervous system in moments of overwhelm.
Take a break – Regular pauses throughout the day help prevent stress from stacking up.

Stress is part of life—but it doesn’t have to run the show. If you’re feeling overwhelmed, don’t wait until it feels unmanageable. Support is here, and you don’t have to go it alone.
