Social connection and health

Overview

Social connection means having close, positive relationships with others. It includes having people you can talk to, trust, and rely on. Social connection is important for your mental and physical health.

Yes, many people experience feelings of loneliness or social isolation at some point in their lives. It is especially common among older adults, but it can affect anyone at any age.

Social connection affects everyone. However, people who live alone, have few friends, or are going through major life changes (like moving, losing a loved one, or retiring) may be more at risk of feeling isolated.

Symptoms

Common symptoms

• Feeling lonely or left out even when you are with others
• Lack of close friends or trusted people to confide in
• Avoiding social activities or feeling anxious about meeting people
• Having few or no social contacts outside your household

Symptoms in children

• Being withdrawn or not wanting to play with other children
• Difficulty making or keeping friends
• Saying they feel lonely or have no one to talk to
• Changes in school performance or behaviour

Symptoms in older adults

• Spending most days alone without visitors or phone calls
• Losing interest in hobbies or groups they used to enjoy
• Feeling that no one understands them or cares
• Physical complaints like tiredness, pain, or poor sleep without a clear medical cause

Causes

Main causes

• Living alone or far from family and friends
• Major life transitions such as retirement, divorce, or bereavement
• Health problems that make it hard to get out and see people
• Lack of social skills or confidence to connect with others
• Social anxiety or other mental health conditions
• Work or caregiving demands that leave little time for relationships

Risk factors

• Being an older adult
• Having a chronic illness or disability
• Being a caregiver for someone with high needs
• Moving to a new area or country
• Having experienced trauma or abuse
• Low income or limited access to transport

When to see a doctor

See a doctor urgently if:

• If you feel so lonely or isolated that you are having thoughts of suicide or self-harm, seek urgent help.

Book a routine appointment if:

• If loneliness or lack of social connection is affecting your mood, sleep, or daily life, talk to a GP or a mental health professional.
• If you have a physical health condition and notice that isolation is making it harder to manage, bring this up at your next appointment.

Diagnosis

There is no single test for social connection. Doctors usually ask about your relationships, how often you see others, and how you feel about your social life. They may also check for underlying conditions like depression or anxiety.

Tests that may be done

• A short questionnaire about loneliness (e.g., the UCLA Loneliness Scale)
• Mental health screening for depression or anxiety
• A general health check to see if stress or isolation is affecting physical health (blood pressure, sleep, weight)

What to expect at your appointment

The doctor will have a private, non-judgemental conversation. They may ask about your family, friends, and support network. Based on your answers, they can suggest helpful resources, refer you to counselling, or connect you with community programmes.

Treatment

Treatment focuses on improving social connections and reducing loneliness. This can involve learning skills, joining groups, or addressing underlying health issues. There are no specific medications for loneliness, but treating related conditions like depression can help.

Self-care at home

• Start small: call a friend, send a text, or say hello to a neighbour.
• Join a local club, class, or volunteer group that matches your interests.
• Try online communities if in-person contact is difficult.
• Practice being open and listening to others – relationships take time.
• Limit time spent on social media if it makes you feel worse.

Medical treatments

If loneliness is linked to depression or anxiety, a doctor may suggest talking therapies such as cognitive behavioural therapy (CBT). Sometimes antidepressant medication is prescribed, but only after a full assessment and discussion of benefits and risks. Your doctor will work with you to find the best approach.

When is surgery considered?

Not applicable for social connection.

Living with this condition

Living with poor social connection can feel lonely and heavy. Building connections takes small, consistent steps. Even brief interactions – like a smile or a chat with a cashier – can help. Over time, these small efforts add up to a stronger network.

Lifestyle tips

• Schedule regular time with others, even if it's just a weekly phone call.
• Take part in community events, religious services, or exercise classes.
• Consider getting a pet if you are able – companionship from animals can also help.
• Use technology wisely: video calls can be more connecting than texts.

Diet and exercise

Eating a balanced diet and staying active can improve your mood and energy, making it easier to reach out to others. Group exercise like walking clubs or dance classes also combine physical activity with social interaction.

Mental health and emotional wellbeing

Loneliness and isolation can lead to depression, anxiety, and low self-worth. It's important to recognise these feelings and get support. Talk therapy can help you understand and change patterns that keep you isolated.

Prevention

You can lower your risk of loneliness by actively maintaining relationships and reaching out when you feel disconnected. Developing good social habits early in life helps, but it's never too late to build new connections.

Vaccines

Not applicable.

Screening programmes

Some GPs may ask about social isolation during routine check-ups, especially for older adults. If you're worried, you can bring it up yourself.

Complications

If left untreated

• Higher risk of heart disease, stroke, and high blood pressure
• Increased chance of developing depression or anxiety
• Weaker immune system, making you more prone to infections
• Faster cognitive decline and higher risk of dementia in older adults
• Worse outcomes for chronic conditions like diabetes or heart failure

Long-term outlook

The good news is that you can improve your social connections at any age. Even small changes – like one new friendship or joining one group – can make a real difference to your health and happiness. With support and effort, most people find their sense of belonging grows.
