What decides your health? Personal, social and environmental determinants
A determinant of health is anything that makes health better or worse. There are three groups.
Personal factors
- Heredity: genes from your parents. They can raise the risk of some illnesses, such as type 2 diabetes or asthma. Genes are not destiny: habits can lower the risk.
- Resilience: the skill of bouncing back after stress or failure. Resilient people cope better, so stress harms them less.
- Health practices and knowledge: what you eat, how you sleep and move, and whether you know how to look after yourself.
Social factors
- Social support: family, friends, teachers and coaches you can turn to. A strong support network lowers stress and helps recovery.
- Social determinants: income, education, housing, jobs, access to health care, culture and discrimination. Poorer housing or no clinic nearby can mean poorer health, even with good habits.
- Sex and gender identity: some health needs differ by sex (for example some screenings), and people may face different stress or barriers because of gender identity. Respect and fair access matter.
Environmental factors
Air, water, noise, safe roads, and conditions at school or work also shape health.
The six dimensions of wellness
Wellness is actively working to feel and live well. It has six linked parts:
- Physical: activity, food, sleep, no tobacco or drugs.
- Mental: thinking, learning, curiosity, managing study.
- Emotional: knowing and handling feelings and stress.
- Social: healthy friendships and belonging.
- Spiritual: a sense of purpose and values (it does not have to be religious).
- Environmental: a clean, safe space around you.
Things that help wellness: good habits, support, a safe home, money for basic needs and good information.
Complementary and alternative care
Some people also use therapies outside mainstream medicine, such as yoga, meditation, massage, acupuncture, chiropractic care, Ayurveda or herbal products. Some (like yoga and meditation for stress) have good evidence; others have little. Rules: check evidence, use qualified practitioners, tell your doctor, and never stop prescribed medicine on your own.
Changing habits: stages of change and a personal wellness plan
The stages of change model says people change a habit in steps:
- Precontemplation: not thinking about change yet.
- Contemplation: thinking about it, weighing pros and cons.
- Preparation: making a plan and small first moves.
- Action: doing the new habit (first few months).
- Maintenance: keeping it for six months or more.
A slip back (relapse) is normal. You learn from it and climb again.
Making your plan
- Appraise: use tools such as a food diary, step counter, sleep log, stress check-list, fitness test or national activity and food guidelines (for example 60 minutes of activity a day for teens).
- Set a SMART goal: Specific, Measurable, Achievable, Realistic, Time-bound. Example: "Walk 30 minutes, 5 days a week, for 4 weeks."
- Plan for barriers: no time, no money, friends' pressure, low mood. Fix: smaller steps, free options, a buddy, reminders, rewards.
- Track and review each week and adjust.
Healthy communities and health promotion
A healthy community has clean air and water, safe housing, good schools, clinics, parks, safe roads, jobs, healthy food shops and people who look out for each other.
Support services: school counsellors and nurses, help lines, youth centres, food banks, sports clubs, public clinics.
Government policies and programmes: vaccination, clean water rules, tobacco laws, food labelling, school food rules, workplace and school safety rules, anti-bullying policies. In India, for example, a free school meal programme and national immunisation help millions of children.
Health promotion
Health promotion means helping people gain more control over their health, not only treating illness. It works through education, healthy policies and supportive places.
What you can do: run a water-bottle drive, a walk-to-school week or a stress-awareness poster campaign; learn first aid; listen to a friend and guide them to help.
Careers: nurse, doctor, paramedic, dietitian, physiotherapist, personal trainer, counsellor, public health worker, health promoter, recreation leader.
Try it
Rate each of your six wellness parts from 1 to 10 for one week. Pick the lowest. Write one SMART goal for it and tick a box every day you do it.
Key formulas and definitions
- Determinants of health: Personal + Social + Environmental
- Six wellness dimensions: Physical, Mental, Emotional, Social, Spiritual, Environmental
- Stages of change: Precontemplation → Contemplation → Preparation → Action → Maintenance
- SMART goal: Specific, Measurable, Achievable, Realistic, Time-bound
- Health promotion: helping people gain control over their own health
Worked examples
1. Arjun says, "Maybe I should stop drinking cola every day, but I'm not sure." Which stage of change is he in?
He is thinking about it and weighing pros and cons but has no plan yet. That is contemplation (stage 2).
2. Turn "I will get fitter" into a SMART goal.
Specific: jog. Measurable: 20 minutes. Achievable: 4 days a week is possible after school. Realistic: fits the timetable. Time-bound: for the next 6 weeks. Goal: "I will jog 20 minutes, 4 days a week, for 6 weeks, and log it."
3. Sara's family has a history of high blood pressure. She lives near a busy road and has few friends at her new school. Name one personal, one environmental and one social determinant.
Personal: heredity (family history of high blood pressure). Environmental: traffic pollution and noise from the busy road. Social: weak social support at the new school.
Common mistakes
- Thinking health is only about the body. Wellness has six dimensions, including mental, emotional and social.
- Thinking genes decide everything. Heredity raises or lowers risk, but habits and surroundings matter a lot.
- Thinking a relapse means failure. Slipping back is a normal part of the stages of change.
- Thinking health is only a personal job. Income, housing, clinics and government policies shape it too.
