🏠 Six Types of Environmental Factors
1. Home Environment
Our environment combines physical factors (where you live) and social factors (people around you) at home and community levels.
Critical Home-Based Factors:
- Quality of Housing: Poor quality (dampness, inadequate lighting, overcrowding) → higher rates of depression, anxiety, stress
- Clutter and Organization: Cluttered homes → increased stress hormones (especially in women)
- Overcrowding: Lack of privacy and control → stress and mental fatigue
📊 Research Finding: Adolescent Girls in Lucknow
- Girls with restrictive home environments or poor parental communication were 2.83-3.65 times more likely to experience anxiety and depression
- Key risk factors: unnecessary restrictions, inability to discuss problems with parents
Study Alert: A study of 60 dual-income couples found women in cluttered homes had higher cortisol levels and heightened depression symptoms.
2. College Environment & Mental Health
Positive Factors:
- Physical Campus: Well-designed, clean, safe, well-equipped → greater well-being, lower anxiety
- Facilities & Security: Accessible resources (health centers, sports facilities) → better psychological well-being
- Social Climate: Good peer relationships → reduced stress
- Sense of belonging ("I am happy to be part of this college!")
- Support systems: professors, social workers, psychologists

3. Physical Factors
