The silence that sickens: when not talking becomes a health risk
Unwanted loneliness is not just a feeling. It is a health risk factor as serious as smoking 15 cigarettes a day, according to researchers at Brigham Young University. It increases the risk of cognitive decline by 50%, raises blood pressure, and weakens the immune system. The World Health Organization has declared it a global public health priority.
In Spain, more than two million people over 65 live alone. Many go entire days without a meaningful conversation. Social isolation has become a silent crisis affecting those in depopulated rural areas and large cities alike, where the paradox of being surrounded by people without close relationships is equally damaging.
What makes this so concerning is that silence feeds on itself. The more days a person goes without talking, the less inclined they feel to start a conversation. Social skills grow rusty, self-confidence drops, and the person enters a cycle of isolation that becomes increasingly difficult to break from the outside.
What the science says about talking every day
Research in psychogerontology has shown that daily conversation simultaneously activates brain areas linked to memory, language, emotions, and executive function. A University of Michigan study published in Social Psychological and Personality Science found that ten minutes of social conversation improves cognitive performance at the same level as ten minutes of structured mental exercises.
You do not need to discuss complex topics. Studies confirm that everyday conversations about the weather, meals, daily plans, or memories of the past have the same protective effect as deep discussions. What truly matters is the regularity of contact: the brain needs daily verbal stimulation to keep its neural connections active.
Moreover, talking activates the brain's reward system, releasing oxytocin and lowering cortisol, the stress hormone. This explains why older adults who maintain regular conversations show fewer symptoms of anxiety and depression, better sleep quality, and a more positive perception of their own health.
Barriers that prevent daily conversation
Many families want to call every day, but reality gets in the way. Work schedules, time-zone differences when children live in another city, the demands of daily life, and accumulated fatigue mean that good intentions often fade. According to a CIS survey, 68% of adult children say they would like to speak more often to their elderly parents but cannot find the time.
There are barriers on the older person's side too. Many do not want to be a bother, feel they no longer have anything interesting to say, or believe that calling too often makes them a nuisance. Pride and a lifelong habit of not asking for anything become invisible walls that keep them silent even with the phone right beside them.
Reduced mobility, hearing loss, and unfamiliarity with technology are also real obstacles. Not every older person can comfortably use a smartphone, and many have no one left to call as their social circle has shrunk over the years. Breaking these barriers requires solutions that adapt to the person, not the other way round.
How families can encourage daily conversation
The first step is to set a fixed time. Whether it is five minutes or thirty, what counts is regularity. A call every morning at ten or every evening after dinner creates a routine the older person can look forward to and gives shape to their day. Predictability builds emotional security.
Getting more people involved in a calling routine is key to making it sustainable. A shared rota among siblings, grandchildren, nieces and nephews, or even neighbours spreads the responsibility and ensures the person never goes an entire day without speaking to someone. A variety of conversation partners also keeps things interesting and enriches the interaction.
It helps to have topics ready. Asking what they had for lunch, whether they went for a walk, what they saw on television, or recalling a family story together are all simple ways to start a natural chat. What matters most is that the older person feels heard and valued, not interrogated.
The habit that protects: routine, expectation, and purpose
Maria calls every day at the same time. It is not by chance. Routine creates expectation, and expectation gives structure to the day. For an older person living alone, having something to look forward to in the morning completely transforms how they experience the day. It goes from being empty to having at least one guaranteed moment of connection.
Gerontology experts point out that temporal structure is essential for the well-being of older adults. Without anchor points in the day, it is easy to slip into inactivity, lethargy, and disorientation. A daily call acts as an anchor that organises everything else: before the call there is something to prepare for, afterwards there is something to think about and remember.
That small daily ritual goes beyond companionship. It creates a sense of purpose — a feeling of being someone who matters enough for another person to think of them every single day. For many older adults, that sense of being remembered is as therapeutic as any medication.
When silence becomes an emergency
Not all silence is equal. Some older adults genuinely enjoy peace and quiet and lead fulfilling lives without needing to talk every day. The problem arises when the silence is not a choice — when the person stops talking because they have lost motivation, because there is no one to call, or because they feel they no longer matter to anyone.
Warning signs include neglecting self-care, unintentional weight loss, missed medication, spending hours or days shut away in their room, and expressions of hopelessness such as 'what is the point' or 'it does not matter'. If you spot these signs in your loved one, it is time to act without waiting for things to get worse.
Speaking to their GP is an essential step. Prolonged absence of conversation can mask or worsen conditions such as depression, mild cognitive impairment, or chronic anxiety. A professional can assess the situation and recommend social, psychological, or community support resources tailored to the person's needs.
Building a conversation habit that lasts
The key is not a one-off gesture but consistency. Just as physical exercise does not work if you only do it once a month, conversation needs to happen daily to produce its protective effects. Research from the University of Exeter shows that the cognitive and emotional benefits begin to emerge after the second week of sustained daily contact.
For the habit to be sustainable, it must be easy. Calling a phone number they already know, speaking to a voice that feels familiar, at a time that is part of their routine. The fewer barriers there are, the more likely the conversation is to continue over time. Services like Hermet are designed around precisely this principle: simplicity, regularity, and warmth.
The ultimate goal is not to replace family connection but to make sure no day passes in silence. That every older person has at least one moment each day when someone listens to them, asks how they are, and reminds them that they matter. Simple as it sounds, that can change a life.
