Before You Judge Me

Living in solitude for five years without touch would have severe, harmful effects on the body, disrupting hormonal balance, cognitive function, cardiovascular health, and immunity. Humans are a social species, and the lack of physical and social connection triggers a powerful and persistent stress response that impacts nearly every biological system. 

Endocrine and physiological changes

Prolonged social and physical isolation unleashes a chronic stress response in the body. 

• Elevated stress hormones: The body will experience a cascade of stress hormones, primarily cortisol, which increases heart rate, blood pressure, and muscle tension. Chronic elevation of cortisol and other stress-response molecules can increase wear and tear on blood vessels.
• Oxytocin deficiency: Physical touch promotes the release of oxytocin, a hormone that creates feelings of happiness, bonding, and well-being. The absence of touch leads to an oxytocin deficiency, which increases feelings of stress, loneliness, and depression.
• Sleep disruption: Loneliness and isolation are known to cause fragmented sleep patterns, which affects overall health and healing. 

Cardiovascular system

Chronic loneliness and isolation have a profound effect on the heart and circulatory system. 

• Increased risk of heart disease and stroke: Studies have found that social isolation is associated with a 29% increased risk of heart disease and a 32% increased risk of stroke.
• High blood pressure: Chronically lonely individuals have higher blood pressure and increased peripheral vascular resistance.
• Inflammation: The persistent stress response from isolation and loneliness leads to chronic inflammation throughout the body, further heightening the risk of chronic disease. 

Immune system

A severely weakened immune system is a major consequence of long-term isolation. 

• Suppressed immune function: The constant state of stress suppresses the immune system, making the body more vulnerable to infections and viruses.
• Chronic inflammation: The chronic elevation of stress hormones also contributes to an immune response that creates harmful inflammation. This reduces the production of antibodies needed to fight off disease. 

Brain and cognition

Long-term isolation significantly impairs brain function and mental health. 

• Increased risk of dementia: The risk of developing dementia, including Alzheimer's disease, significantly increases with social isolation.
• Cognitive decline: Five years of solitude can accelerate cognitive decline, leading to problems with executive functions like memory, attention, and verbal fluency.
• Mental health disorders: The experience is likely to cause or exacerbate severe mental health issues, such as depression, anxiety, paranoia, and suicidal ideation.
• Altered brain structure: Research suggests that social isolation can alter brain regions critical for emotional control and thinking. 

Effects of touch deprivation

Beyond social isolation, the complete absence of physical touch, a condition called "touch starvation," has its own distinct set of negative consequences. 

• Negative emotions: A lack of physical contact contributes to loneliness, depression, and stress.
• Primitive need: Touch is a primitive human need. The body's craving for it is similar to hunger, and being deprived of it is highly distressing.
• Developmental impairment: The effect is especially devastating for children. Extreme touch deprivation, as seen in the Romanian orphanages in the 1990s, led to severe developmental delays, both physically and mentally. While less dramatic, the long-term effects of touch deprivation would still be profoundly damaging for an adult.
