Cultural Factors have strong influence on consumer buyer behavior. Cultural Factors include the basic values, needs, wants, preferences, perceptions, and behaviors that are observed and learned by a consumer from their near family members and other important people around them.

The perceptions consumers have of a business and its products or service have a dramatic effect on buying behavior. That’s why businesses spend so much money marketing themselves, honing their customer service and doing whatever else they can to favorably influence the perceptions of target consumers.

There are four psychological factors that influence consumer behaviour: Motivation, perception, learning, and attitude or belief system.

Tiny air pollution particles can trigger immune system cells that cause inflammation, a potential pathway for an aberrant immune response, say the researchers. Previous studies have suggested that air pollution may play a role in the development of IBD.

Things That Suppress Your Immune System

• 1 / 13. Lack of Sleep. Not getting enough sleep can make you more likely to catch viruses or germs.
• 2 / 13. Anxiety.
• 3 / 13. Low Vitamin D.
• 4 / 13. Certain Medications.
• 5 / 13. Too Few Fruits and Veggies.
• 6 / 13. Marijuana.
• 7 / 13. High-Fat Diet.
• 8 / 13. Too Little Time Outdoors.

Our age, sex, infection history, and genetics can affect our immune system and make us more prone to disease.

Researchers keep learning how genes affect immune disorders. For example, one genetic defect may block certain cells defending the body. Another defect might stop the removal of toxic chemicals from the body.

Humans have three types of immunity — innate, adaptive, and passive:

• Innate immunity: Everyone is born with innate (or natural) immunity, a type of general protection.
• Adaptive immunity: Adaptive (or active) immunity develops throughout our lives.

A new study has found genetics are the key to a strong immune response to viruses, not the environment around us as previously believed. The genes passed to us by our parents play a bigger role in the body’s disease-fighting ability than scientists previously thought.

Autoimmune disease is also thought to happen due to an overactive immune system. Healthy lifestyle habits cannot make your immune system too strong. Normally immune systems that fight themselves are due to genetic factors in the innate immune system.

The bad news is that as we age, our immune systems gradually deteriorate too. This “immunosenescence” starts to affect people’s health at about 60, says Janet Lord at the University of Birmingham, UK.
