Sitting too much is harming your heart

While exercise is crucial, recent findings from the Journal of the American College of Cardiology [1] reveal that meeting weekly exercise guidelines might not fully counteract the risks posed by excessive sedentary behaviour. This research underscores the importance of reducing sitting time for better heart health.

The Impact of Sedentary Behaviour

The study, which tracked nearly 90,000 participants over eight years, revealed startling statistics: those who sat for over 10 hours daily were at a 40% to 60% higher risk of heart failure and cardiovascular-related death compared to those who sat less. 

Excessive sitting was also linked to:

• Atrial fibrillation (irregular heart rhythm)
• Heart failure
• Myocardial infarction (heart attack)
• Increased cardiovascular mortality

Even among participants who met physical activity guidelines, prolonged sitting significantly raised the risk of heart failure and death.

Why Sitting Affects Your Heart

When we sit for extended periods, metabolic and cardiovascular processes slow down. Blood circulation decreases, and enzymes involved in breaking down fats are suppressed. Over time, this can lead to:

1. Decreased insulin sensitivity, increasing the risk of Type 2 diabetes.
2. Weakened heart muscles, as the heart isn’t challenged to pump as efficiently.
3. Increased fat deposition, particularly around the abdomen, which is a risk factor for cardiovascular disease.

The Importance of Moving More

While meeting aerobic activity guidelines [2] (150–300 minutes of moderate activity or 75–150 minutes of vigorous activity weekly) is essential, incorporating movement throughout the day is equally important. Breaking up sedentary time with light activities, even for a few minutes, can have a profound impact on your health.

Ways to Stay Active Throughout the Day

1. Take Micro-Breaks: Stand up and stretch every 30 minutes.
2. Incorporate Active Transportation: Walk or cycle for short trips instead of driving.
3. Active Meetings: Take calls or attend virtual meetings while walking.
4. Use a Standing Desk: Alternate between sitting and standing while working.
5. Walk After Meals: A short walk post-meal aids digestion and boosts circulation.
6. Set Movement Alarms: Use a fitness tracker or phone reminders to prompt movement.
7. Household Chores: Activities like gardening or vacuuming count as light exercise.
8. Lunchtime Workouts: Incorporate a 10–15-minute resistance or cardio session.

Start Building an Active Lifestyle

Exercise and resistance training are integral to reversing the effects of prolonged sitting. Strengthening muscles and improving cardiovascular health can mitigate the risks associated with a sedentary lifestyle.
