The World Health Organization puts the yearly total at more than 871,000 deaths and estimates that one in six people worldwide are affected by loneliness. So can you die from loneliness? Nobody has loneliness written on a death certificate. It works slowly instead, through your sleep, your stress hormones, your blood pressure and your brain, and over years it raises your risk of stroke, heart disease, diabetes, dementia and early death. Loneliness and isolation are different things. Isolation means having few social ties. Loneliness is the painful feeling that comes from a gap between the relationships you have and the relationships you want. You can feel lonely in a full office, at a family dinner or inside a long marriage, and the effects on your body are real either way. ## 7 Things Loneliness Does to Your Body ### 1. It Keeps Your Stress Response Switched On For most of human history, being cut off from your group meant danger. Your brain still treats disconnection as a threat, and it responds by keeping stress hormones such as cortisol raised. In short bursts this response protects you. Kept up for months, it wears down almost every system in your body. ### 2. It Breaks Up Your Sleep Loneliness is linked to lighter, more broken sleep. A brain on alert for threat stays partly watchful at night, so you wake more often and feel less rested in the morning, even after a full eight hours in bed. ### 3. It Raises Inflammation Long-term stress pushes your immune system into a low level of constant inflammation. This kind of inflammation plays a part in heart disease, type 2 diabetes and several other long-term conditions. Strong social connection does the opposite and is linked to lower inflammation. ### 4. It Strains Your Heart Loneliness and isolation raise your risk of heart disease and stroke. Raised stress hormones, higher blood pressure and inflammation all put extra load on your heart and blood vessels over time. Our guide to [building friendships in midlife](https://richhealthmagazine.com/article/loneliness-making-friends-midlife) has eight practical ways to protect your heart through connection. ### 5. It Weakens Your Defences Against Illness Social connection lowers your risk of serious illness, and loneliness removes that protection. Lonely people are also less likely to have someone who notices early warning signs, nudges them to see a doctor or helps them recover after an illness. ### 6. It Speeds Up Cognitive Decline Loneliness is linked to faster decline in memory and thinking. Conversation is one of the most demanding tasks your brain performs, and regular contact with other people keeps those networks in use. ### 7. It Doubles Your Risk of Depression Lonely people are twice as likely to experience depression and are more prone to anxiety. Low mood then makes it harder to reach out, which can deepen the loneliness.

Poor health, low income, living alone and limited education all raise it, as do neighbourhoods with few places to meet. Young people are especially vulnerable, and heavy screen use and harmful online contact can make the feeling worse. Life changes are common triggers. Retirement, divorce, bereavement, moving to a new city, working from home and children leaving home can all remove your main sources of daily contact at once. ## How to Reverse Loneliness: 6 Steps ### 1. Aim for One Real Conversation a Day Contact matters more than numbers. A five-minute phone call with someone who knows you does more for your stress response than an evening of scrolling through other people's lives. ### 2. Turn Familiar Faces Into Regular Ones The neighbour you nod to, the person at the coffee counter and the regular at your gym are all easy places to start. Small, repeated contact builds familiarity, and familiarity is where many friendships begin. ### 3. Join Something That Meets Every Week A choir, a walking group, a book club or a regular volunteering shift gives you the same faces at the same time each week. A shared task also takes the pressure off conversation, which makes it easier to connect. ### 4. Put Your Phone Out of Reach When You Are With People A phone on the table pulls your attention away even when it stays silent. Keep it in a bag or another room during meals and meetings with friends, and you will notice the conversation goes deeper. ### 5. Say Yes Before You Feel Ready Loneliness makes your brain more alert to rejection, so invitations can feel riskier than they are. Accept the next one, even for an hour. Most people are more pleased to hear from you than you expect. ### 6. Ask Your GP About Social Prescribing Many GP practices in England have link workers who can connect you with local groups, classes, volunteering and community support. Ask at your surgery about social prescribing, and say plainly that you feel lonely. ## FAQ **Q: Can you die from loneliness?** Loneliness is not a direct cause of death, but it is linked to more than 871,000 deaths worldwide every year, according to the World Health Organization. Over time, loneliness raises your risk of stroke, heart disease, diabetes, cognitive decline, depression and early death. It does this through long-term stress, poor sleep, higher blood pressure and inflammation. **Q: What is the loneliness epidemic?** The loneliness epidemic is a term for the high and growing number of people who feel lonely despite living in a more connected world. The World Health Organization estimates that one in six people worldwide are affected and has called on governments to treat social connection as a public health priority. Young people and those in low and middle income countries are among the most affected. **Q: What is the male loneliness epidemic?** The male loneliness epidemic describes concern that many men have few close friendships and are less likely than women to talk about feeling lonely or to seek help. Men often build friendships around shared activities such as work or sport, so retirement, divorce, a move or a change of job can remove their main source of contact at once. **Q: How do you cope with loneliness?** Start with small, regular contact: one conversation a day with someone you know, or a chat with a familiar face such as a neighbour. Join an activity that meets weekly, such as a walking group, a class or a volunteering shift, so you see the same people often. Limit time spent scrolling social media, and speak to your GP if loneliness is affecting your mood or sleep, as many practices can link you to local groups.
