Health at work: practical habits for people who sit all day


Many people spend eight or more hours a day sitting in front of a screen, with rushed meals and little time to move. Over the months, this routine shows up as back pain, tiredness, difficulty concentrating and poorer sleep. You do not need to change everything at once: small adjustments, repeated every day, make a real difference.

Start the day well

The way your morning begins shapes the rest of your working day.

  • Get enough sleep: most adults need 7 to 9 hours of sleep a night. Keeping regular times for going to bed and getting up, even at weekends, helps the body rest better.
  • Wake up with time to spare: getting up early enough to eat breakfast sitting down, rather than on the way, reduces stress first thing in the morning.
  • A balanced breakfast: combining a source of protein (plain yoghurt, eggs, fresh cheese), fibre-rich carbohydrates (wholemeal bread, oats) and fruit provides steady energy until lunch.
  • Move before work: a 15 to 20 minute walk, walking to the bus or a short workout at home wakes the body up and improves your mood.

Set up your workstation

Good posture starts with how your desk is arranged:

  • The top of the screen should be at eye level or slightly below, about an arm's length away.
  • Your feet should rest flat on the floor (or on a footrest), with your knees roughly level with your hips.
  • Your elbows should stay close to your body, bent at about 90 degrees, with your shoulders relaxed.
  • If you work on a laptop for many hours, an external keyboard and mouse help, with the screen raised on a stand.
  • To rest your eyes, follow the 20-20-20 rule: every 20 minutes, look at something about 6 metres away for 20 seconds.

Break up sitting time

Sitting for many hours in a row has negative effects, even for people who exercise at other times of the day. The answer is to break up that time often:

  • Stand up at least every 30 to 60 minutes, even if only for 2 or 3 minutes.
  • Take phone calls standing or walking.
  • Use the stairs instead of the lift, and go and speak to a colleague in person instead of sending a message.
  • Do simple stretches: roll your shoulders, tilt your head to each side, reach your arms above your head and stretch the backs of your legs.
  • Use part of your lunch break for a 10 to 15 minute walk.

An alarm on your phone or a reminder on your computer helps build the habit in the first few weeks.

Eating and drinking through the day

Food at work is often the most neglected part of the routine.

  • Bring a packed lunch: preparing lunch at home lets you control ingredients and portions, and it is usually cheaper. A practical rule is to fill half the box with vegetables, a quarter with protein (fish, lean meat, eggs or pulses) and a quarter with carbohydrates (rice, pasta, potatoes or whole grains).
  • Plan your snacks: keeping fruit, a handful of nuts (about 30 g) or a yoghurt to hand avoids trips to the vending machine.
  • Drink water regularly: keeping a bottle on your desk makes it easier. For most adults, around 1.5 to 2 litres of fluid a day is a good guide.
  • Watch the coffee: in moderation it can be part of your day, but it is best to avoid coffee in the 6 hours before bedtime so it does not disturb your sleep.
  • Eat away from the screen: taking a proper lunch break helps you notice when you are full and gives your mind a rest.

Look after your mind and end the day well

Wellbeing at work is not only physical. Managing stress counts too:

  • Organise tasks by priority at the start of the day and set aside blocks of time without notifications for work that needs concentration.
  • Take short breaks to breathe deeply: breathe in for 4 seconds and out for 6, repeating 5 times.
  • Set a finishing time and switch off work notifications outside those hours whenever possible.
  • Make time for regular physical activity: the general recommendation for adults is at least 150 minutes a week of moderate activity, such as brisk walking, swimming or cycling.

In summary

Getting enough sleep, setting up your workstation, standing up often, bringing balanced meals, drinking water and protecting your rest time are simple habits that improve energy, concentration and long-term health. The best approach is to choose two or three changes, keep them up for a few weeks and then add more.
