Physical Activity & Everyday Lifestyle
How much activity adults need, how to start safely and how sleep and sitting time fit in.
This guide is educational information, not medical advice, diagnosis or treatment. It cannot replace a qualified doctor. In an emergency call your local emergency number (112 in India) or go to the nearest hospital.
Regular movement lowers the risk of heart disease, type 2 diabetes, several cancers, anxiety and depression. Global guidance for adults is 150–300 minutes of moderate aerobic activity a week plus muscle-strengthening on two days. Reducing long uninterrupted sitting matters independently of workout time.
Key concepts
- Moderate versus vigorous intensity, judged by the talk test
- Progressive overload: increase load or duration gradually
- Recovery and sleep are part of training, not a break from it
- NEAT: everyday movement such as walking and stairs adds up
Risk factors
- Sedentary work with long unbroken sitting
- Sudden intense exercise after months of inactivity
- Poor sleep and high chronic stress
Prevention
- Aim for 150 minutes of brisk activity a week, split any way that fits
- Add two strengthening sessions covering major muscle groups
- Break up sitting every 30–45 minutes
- Protect 7–9 hours of sleep with a consistent schedule
Self-care
- Warm up and cool down; increase intensity by about 10% a week
- Hydrate and adjust outdoor activity in extreme heat
- Track steps or sessions to keep the habit visible
When to seek professional help
- Chest pain, severe breathlessness or fainting during exertion — urgent
- Joint pain that persists after rest
- Before starting intense exercise with a heart, lung or metabolic condition
