Physical activity is one of the most powerful tools for preventing and managing chronic disease. The World Health Organization describes physical inactivity as the fourth leading risk factor for global mortality. In the UAE, where lifestyle diseases are prevalent, regular exercise can make a significant difference to health outcomes.
How Much Exercise Do You Need?
The WHO, NHS, and most health authorities recommend:
Adults (18-64 years)
- At least 150 minutes of moderate-intensity aerobic activity per week (e.g., brisk walking, cycling, swimming)
- OR 75 minutes of vigorous-intensity activity per week (e.g., running, high-intensity interval training)
- Plus muscle-strengthening activities on 2 or more days per week
- Reduce sedentary time and break up long periods of sitting
Children and Adolescents (5-17 years)
- At least 60 minutes of moderate-to-vigorous physical activity daily
- Include vigorous activity and muscle-strengthening at least 3 days per week
Older Adults (65+)
- Same as adults, plus activities that maintain or improve balance and flexibility (to prevent falls)
Proven Health Benefits
Cardiovascular Health
- Reduces the risk of heart disease by 35%
- Lowers blood pressure (average reduction of 5-8 mmHg in hypertensive individuals)
- Improves cholesterol profile (raises HDL, lowers triglycerides)
- Reduces risk of stroke by 20-30%
Diabetes Prevention and Management
- Reduces the risk of developing type 2 diabetes by up to 58% (Diabetes Prevention Program study)
- Improves insulin sensitivity
- Helps with blood sugar control (exercise can lower HbA1c by approximately 0.7%)
Weight Management
- Exercise combined with dietary changes is more effective than diet alone
- Helps maintain weight loss long-term
- Reduces harmful visceral (abdominal) fat
Mental Health
- Reduces symptoms of depression by 20-30% (comparable to some medications for mild-moderate depression)
- Reduces anxiety
- Improves sleep quality
- Boosts self-esteem and cognitive function
- NICE recommends exercise as a treatment option for mild to moderate depression
Bone and Joint Health
- Weight-bearing exercise increases bone density and reduces osteoporosis risk
- Strengthens muscles that support joints
- Reduces pain and improves function in osteoarthritis
- Helps prevent falls in older adults
Cancer Risk Reduction
- Physically active people have a 20-30% reduced risk of colon cancer
- Regular exercise reduces breast cancer risk by approximately 20%
- Evidence also supports reduced risk of bladder, endometrial, and gastric cancers
Brain Health
- Improves memory and cognitive function
- Reduces risk of dementia by approximately 30%
- Increases brain-derived neurotrophic factor (BDNF), which supports brain cell growth
Getting Started Safely
If You Are New to Exercise
- Start slowly and gradually increase duration and intensity
- Walking is an excellent starting point - begin with 10-15 minutes daily and build up
- Choose activities you enjoy - you are more likely to continue
- Set realistic, achievable goals
Exercise in the UAE Climate
- Avoid outdoor exercise during peak heat (11am-4pm in summer months)
- Exercise early morning or evening when temperatures are lower
- Stay well-hydrated before, during, and after exercise
- Use indoor facilities (gyms, swimming pools, air-conditioned walking areas) during extreme heat
- Wear lightweight, breathable clothing
When to See Your Doctor Before Starting
- If you have a heart condition or have had a cardiovascular event
- If you have uncontrolled diabetes
- If you experience chest pain, dizziness, or shortness of breath with mild activity
- If you have joint problems that are aggravated by exercise
- If you have blood pressure that is not yet controlled
- If you have not exercised for a long time and are over 45
Types of Exercise
- Aerobic (cardio): Walking, jogging, cycling, swimming, dancing - benefits the heart and lungs
- Resistance (strength): Weight lifting, resistance bands, bodyweight exercises - builds muscle and bone
- Flexibility: Stretching, yoga, Pilates - improves range of motion and reduces injury risk
- Balance: Tai chi, standing on one leg - especially important for older adults
The best programme includes a combination of these types.
