Marriage is a union that happens when we believe in the magic of love and companionship in making our life complete and fulfilled. Emotional support is usually not considered a top priority while choosing a spouse. Sometimes, people may enter marriages for some other reasons like appearance, instant chemistry, financial stability, convenience, or simply achieving a milestone. This article highlights the significance of having an emotionally supportive and present partner for upholding a sustainable and healthy marriage. It won’t be wrong to say “your health literally relies on the quality of your marriage”. Research has shown chronic relationship stress originating from loneliness in a marriage can increase cortisol levels, disrupt sleep cycle and contribute to weight gain.

Here is a list of 15 ways in which an emotionally unsafe and lonely marriage impacts your mental health, physical health and a sense of overall wellness.

Emotional Loneliness Can Trigger Stress Eating

When someone is kept starved for love and attention for too long, despite being in a marriage, their stress level rises. Uncontrolled snacking, stress eating or cooking becomes their escape from the chaos of life, which eventually leads to excess weight gain.

Loneliness Can Increase Stress Hormones

There is real chemistry involved behind the sudden weight change and health decline. With loneliness and emotional isolation there is a spike in the level of cortisol, the stress hormone which slows down metabolism and causes unnecessary fat deposition around the abdomen.

Lack of Emotional Support Can Reduce Motivation

The emotional neglect by your partner dampens the motivation in you to look after your emotional and physical well-being. You stop putting effort into trying to maintain fitness, eat healthy or focus on acts of selfcare.

Marital Conflict Can Encourage Unhealthy Habits

When the marriage is constantly going through emotional turbulence you not just become chronically depressed you also become too demotivated to pursue healthy habits. To shift focus from overthinking you may turn to unhealthy coping mechanisms like substance abuse, binge watching screens, excessive eating or giving up physical activities altogether.

Feeling Unseen or Unappreciated Affects Mental Health

It’s human nature to feel seen and be cherished by the person they love. When undivided attention, active listening and appreciation are missing in a marriage it takes an immense toll on your mental health and self -esteem.

Loneliness Can Lead to Emotional Withdrawal

When you constantly feel ignored and dismissed in your marriage you end up building walls around your heart. This is your act of self-protection from more heartbreaks. But emotional withdrawal leads to severe psychological repercussions as bottling up ill feelings can negatively affect your overall health.

Emotional Isolation Encourages Comfort Behaviors

When you’re in an emotionally unfulfilling marriage, you turn to other comfort behaviors to seek relief like binge eating, binge watching, or languishing on the couch scrolling your phone for hours. This lifestyle brings about poor health outcomes.

Relationship Satisfaction Can Change Lifestyle Habits

Surprisingly, it’s not just unhappy marriage dynamics that lead to weight gain. Research suggests a satisfied and emotionally secure spouse gains extra pounds too. This happens as they don’t feel the stress to stay in shape or appear perfect to be liked. Their partner loves them unconditionally.

Loneliness Can Affect Sleep Patterns

The emotional safety and satisfaction level of a marriage is positively correlated with good quality sleep and vice versa. When you’re under stress 24/7 , your sleep quality declines and your health goes down each day. Stress disrupts your circadian rhythm and metabolic functions.

Emotional Distance Can Reduce Physical Activity

A lot of couples plan joint activities like gym, trekking, or travelling. They may have a shared fitness routine like going together for jogging or running at the same time of the day. Or helping each other strength train daily. When the connection breaks down these activities also cease to exist, which adds to the inactive lifestyle and the failing health. 

Isolation Within Marriage Can Intensify Depression

Being “alone together” is a form of heartache that an emotionally isolated partner goes through on a daily basis.  The emotional wounds emotional withdrawal causes aren’t visible to the outside world while you crumble under the grief of loneliness and invisibility. Emotionally isolated partners lose themselves deep into depression and thus put on extra pounds.

Couples’ Emotional States Often Influence Each Other

Studies reveal a correlation between the emotional health of both partners. One partner’s mental health issues or depression may directly affect their partners mental health. They both feel too emotionally drained to converse with each other without getting more distressed.

Stress Can Change Appetite and Metabolism

Chronic stress and depression may have consequences far beyond the visible mood changes like irritability, nagging or inconsolable crying spells. It messes with the body’s metabolic rate and alters the hunger cues and hence the appetite, which either makes you feel too full to eat or too hungry to stop eating.

Lack of Communication Can Deepen Emotional Gaps

When there is a lack of healthy and honest communication between a couple, dissatisfaction ensues. When unresolved issues never get resolved, the distance grows till you start feeling like two roommates rather than life partners.

Rebuilding Connection Can Improve Health

The good news is that there is a solution to loneliness in a marriage. Convey your grievances and concerns to each other in a respectful way, openly appreciate each other, resume joint physical activities or hobbies and support each other emotionally. Work together as a team towards better health goals.

Final Thoughts

Loneliness in marriage is a phenomenon more common than you may think; many couples go through this phase where they lose connection and attraction completely. This becomes too painstaking when one partner is constantly at the receiving end of their partner’s apathy and insensitivity. This emotional neglect affects not just the mental health in the form of depression and anxiety but leads to many physical and physiological changes in the body. Hormonal disruptions and metabolic changes happen which cause high cortisol, reduced motivation, decreased activity, poor sleep and increased weight gain. The key takeaway from this article is to pay close attention to prioritizing each other’s emotional well-being and happiness will be yours forever.
