IN AN IDEAL world, I might be a triathlete, but juggling work, family, and caregiving means a weekly swim feels like an achievement. We’re advised to get 150 minutes of moderate-intensity exercise weekly, yet a quarter of us need to manage 30 minutes. Is there a more straightforward target that can still boost our health?
Go Fast, or Go Far?
The key to maximising results with minimal time is intensity. Higher-intensity sessions are necessary if exercise time is reduced. Official guidelines suggest 75 minutes of vigorous activity as an alternative to 150 minutes of moderate exercise. High-intensity interval training (HIIT) is popular, but many find it too intense to maintain.
The Bare Minimum
Go for 5,000 to 6,000 steps a day as a realistic goal; simple actions like getting off the bus early or taking a lunch break walk can make a difference. A study in JAMA Internal Medicine found that increasing daily steps reduces the risk of cancer, cardiovascular disease, and early death. Benefits increase to 10,000 steps daily, but faster steps are more effective than slow ones.
A Nature Medicine study highlighted the health benefits of short bursts of vigorous activity in daily life. Activities like running for a train, vacuuming, or playing with kids can significantly reduce the risk of heart disease and cancer by up to 50%, even if they total just three to four minutes daily. Prof. Mark Hamer from University College London notes that guidelines now emphasise “anything counts” in promoting health.
Lie Back in the Bath – and Get Fit?
Hot baths, hot tubs, or saunas offer an alternative for those pressed for time. Immersing in a 40°C bath makes the body work hard to shed heat, similar to light-intensity exercise. This process can reduce blood pressure and mimic some benefits, though exercise remains the most effective option. Combining exercise with sauna or hot tub sessions might enhance health benefits, but caution is advised to avoid overheating.
Practical Tips for Incorporating Minimal Exercise
For those struggling to meet exercise guidelines, consider these practical tips to integrate more physical activity into your daily routine:
- Walk More: Aim for 5,000 to 6,000 steps a day. Use stairs instead of elevators, park further away from your destination, and incorporate short walks during breaks.
- Short Bursts of Activity: Incorporate high-intensity activities into your routine. It can include brisk walking, running for short distances, or quick home workouts. Even a few minutes a day can make a significant difference.
- Active Commuting: If possible, walk or cycle to work. If you use public transport, leave earlier and walk the rest.
- Household Chores as Exercise: Activities like vacuuming, gardening, or playing with children can be physical activities. Approach these tasks with vigour to increase your heart rate.
- Use Technology: Activity trackers can motivate you to move more. Set daily step goals and track your progress. Many smartphones have built-in pedometers that can help you stay on track.
- Social Activities: Join a walking group or exercise class with friends. Social interaction can make exercise more enjoyable and keep you motivated.
- Combine Exercise with Leisure: Watch your favourite show on a treadmill or listen to audiobooks during a walk. Combining entertainment with exercise can make time pass more quickly.
- Mindful Movement: Practice yoga or tai chi, which provides physical benefits and helps with relaxation and stress reduction.
Conclusion
While the recommended amount of exercise is ideal, significant health benefits can still be achieved by doing a little more than we currently do. Even modest increases in daily activity, higher intensity workouts, or incorporating hot baths and saunas can contribute to better health. The key is to find enjoyable activities and integrate them into your daily routine, making it easier to stick to a more active lifestyle.
