Why STIs Are On The Rise In Older Adults

Three Little Words
Sexually Transmitted Infections (STIs) are often thought of as something that predominantly plagues younger people… The truth, however, is different:
❝Rising divorce rates, forgoing condoms as there is no risk of pregnancy, the availability of drugs for sexual dysfunction, the large number of older adults living together in retirement communities, and the increased use of dating apps are likely to have contributed to the growing incidence of STIs in the over-50s.
These data likely underestimate the true extent of the problem as limited access to sexual health services for the over 50s, and trying to avoid the stigma and embarrassment both on the part of older people and healthcare professionals, is leading to this age group not seeking help for STIs.❞

That said, there is a gender gap when it comes to the increased risk, for example:
❝A retrospective study from the USA involving 420,790 couples aged 67 to 99 years, found that widowhood was associated with an increased risk of STIs in older men, but not women❞

Is abstinence the best preventative, then?
It is inarguably the most effective, but not necessarily the best for everyone.
This is because for most adults, a healthy sex life is an important part of overall wellbeing.

Even in this case there is a gender gap in:
- the level of importance placed on frequency of sexual interactions
- what act(s) of sexuality are held to be most important:
❝Among sexually active men, frequent (≥2 times a month) sexual intercourse (P < .001) and frequent kissing, petting, or fondling (P < .001) were associated with greater enjoyment of life.
Among sexually active women, frequent kissing, petting, or fondling was also associated with greater enjoyment of life (P < .001), but there was no significant association with frequent intercourse (P = .101).
Concerns about one’s sex life and problems with sexual function were strongly associated with lower levels of enjoyment of life in men and to a lesser extent in women.❞

If you have the time to go into it much more deeply, this paper from the Journal of Gerontology is much more comprehensive, looking also at related lifestyle factors, religious/political backgrounds, views on monogamy or non-monogamy (of various kinds), hormonal considerations, the impact of dementia or other long-term disabilities that may affect things, widowhood, and many other elements:
The National Social Life, Health, and Aging Project: An Introduction
What’s the best preventative, then?
Regular health screening for yourself and your partner(s) is an important key to preventative health when it comes to STIs.
You can Google search for a local STI clinic, and worry not, they are invariably discreet and are well-used to everybody coming in. They’re just glad you’re being responsible about things. It’s also not their job to judge your sexual activities, even if it’s something you might have reason to wish to be secretive about, try to be honest there.
Secondly, most of the usual advice about safe sex still goes, even when there’s no risk of pregnancy. For example, if there’s at least one penis involved, then condoms remain the #1 barrier to all manner of potential infections (we know, almost nobody likes condoms, but sometimes the truth isn’t what we want to hear).
Lastly, if there’s at least one vagina involved, then please for the love of all that is holey, do not put anything there that could cause a yeast infection.
What can cause a yeast infection? Pretty much anything with sugar, which includes but is not limited to:
- Most kinds of food that Cosmo-style “liven things up in the bedroom” advice columns might suggest using (including fruit, honey, chocolate sauce, whipped cream, etc)
- Hands that are not clean (watch out for bacteria too)
- A mouth that has recently been eating or drinking anything with sugar in it, and that includes many kinds of alcohol, as well as milk or hot drinks that had milk in
Yeast infections are not nearly so serious as the STIs the other measures are there to avoid, but they’re not fun either, so some sensible policies in that regard are always good!

Recap on the single most important part of this article:
At all ages, it remains a good health practice—unless one is absolutely celibate—to regularly get oneself and one’s partner(s) checked for STIs.
Take care!

14 Powerful Strategies To Prevent Dementia
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Dementia risk starts climbing very steeply after the age of 65, but it’s not entirely predetermined. Dr. Brad Stanfield, a primary care physician, has insights:
The strategies
We’ll not keep them a mystery; they are:
- Cognitive stimulation: which means genuinely challenging mental activities using a variety of mental faculties. This will usually mean that anything that is just “same old, same old” all the time will stop giving benefits after a short while once it becomes rote, and you’ll need something harder and/or different.
- Hearing health: being unable to participate in conversations increases dementia risk; hearing aids can help.
- Eyesight health: similar to the above; regular eye tests are good, and the use of glasses where appropriate.
- Depression management: midlife depression is linked to later life dementia, likely in large part due to social isolation and a lack of stimulation, but either way, treating depression earlier reduces later dementia risk.
- Exercising regularly: what’s good for the heart is good for the brain; the brain is a hungry organ and the blood is what feeds it (and removes things that shouldn’t be there)
- Head injury avoidance: even mild head injuries can cause problems down the road. Protecting one’s head in sports, and even while casually cycling, is important.
- Smoking cessation: just don’t smoke; if you smoke, make it a top priority to quit unless you are given direct strong medical advice to the contrary (there are cases, few and far between, whereby quitting smoking genuinely needs to be deferred until after something else is dealt with first, but they are a lot rarer than a lot of people who are simply afraid of quitting would like to believe)
- Cholesterol management: again, healthy blood means a healthy brain, and that goes for triglycerides too.
- Weight management: obesity, especially waist to hip ratio (indicating visceral abdominal fat specifically) is associated with many woes, including dementia.
- Diabetes management: once again, healthy blood means a healthy brain, and that goes for blood sugar management too.
- Blood pressure management: guess what, healthy blood still means a healthy brain, and that goes for blood pressure too.
- Alcohol reduction/cessation: alcohol is bad for pretty much everything, and for most people who drink, quitting is probably the top thing to do after quitting smoking.
- Social engagement: while we all may have our different preferences on a scale of introversion to extroversion, we are fundamentally a social species and thrive best with social contact, even if it’s just a few people.
- Air pollution reduction: avoiding pollutants, and filtering the air we breathe where pollutants are otherwise unavoidable, makes a measurable difference to brain health outcomes.

Laziness Does Not Exist – by Dr. Devon Price
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Some cultures prize productivity as an ideal above most other things, and it’s certainly so in the US. Not only is this not great for mental health in general, but also—as Dr. Price explains—it’s based on a lie.
Generally speaking, when a person appears lazy there is something stopping them/you from doing better, and it’s not some mystical unseen force of laziness, not a set character trait, not a moral failing. Rather, the root cause may be physical, psychological, socioeconomic, or something else entirely.
Those causes can in some cases be overcome (for example, a little CBT can often set aside perfectionist anxiety that results in procrastination), and in some cases they can’t, at least on an individual level (disabilities often stubbornly remain disabling, and societal problems require societal solutions).
This matters for our mental health in areas well beyond the labor marketplace, of course, and these ideas extend to personal projects and even personal relationships. Whatever it is, if it’s leaving you exhausted, then probably something needs to be changed (even if the something is just “expectations”).
The book does offer practical solutions to all manner of such situations, improving what can be improved, making easier what can be made easier, and accepting what just needs to be accepted.
The style of this book is casual yet insightful and deep, easy-reading yet with all the acumen of an accomplished social psychologist.
Bottom line: if life leaves you exhausted, this book can be the antidote and cure

Stuck in fight-or-flight mode? 5 ways to complete the ‘stress cycle’ and avoid burnout or depression
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
Can you remember a time when you felt stressed leading up to a big life event and then afterwards felt like a weight had been lifted? This process – the ramping up of the stress response and then feeling this settle back down – shows completion of the “stress cycle”.
Some stress in daily life is unavoidable. But remaining stressed is unhealthy. Chronic stress increases chronic health conditions, including heart disease and stroke and diabetes. It can also lead to burnout or depression.
Exercise, cognitive, creative, social and self-soothing activities help us process stress in healthier ways and complete the stress cycle.
What does the stress cycle look like?
Scientists and researchers refer to the “stress response”, often with a focus on the fight-or-flight reactions. The phrase the “stress cycle” has been made popular by self-help experts but it does have a scientific basis.
The stress cycle is our body’s response to a stressful event, whether real or perceived, physical or psychological. It could be being chased by a vicious dog, an upcoming exam or a difficult conversation.
The stress cycle has three stages:
- stage 1 is perceiving the threat
- stage 2 is the fight-or-flight response, driven by our stress hormones: adrenaline and cortisol
- stage 3 is relief, including physiological and psychological relief. This completes the stress cycle.
Different people will respond to stress differently based on their life experiences and genetics.
Unfortunately, many people experience multiple and ongoing stressors out of their control, including the cost-of-living crisis, extreme weather events and domestic violence.
Remaining in stage 2 (the flight-or-flight response), can lead to chronic stress. Chronic stress and high cortisol can increase inflammation, which damages our brain and other organs.
When you are stuck in chronic fight-or-flight mode, you don’t think clearly and are more easily distracted. Activities that provide temporary pleasure, such as eating junk food or drinking alcohol are unhelpful strategies that do not reduce the stress effects on our brain and body. Scrolling through social media is also not an effective way to complete the stress cycle. In fact, this is associated with an increased stress response.
Stress and the brain
In the brain, chronic high cortisol can shrink the hippocampus. This can impair a person’s memory and their capacity to think and concentrate.
Chronic high cortisol also reduces activity in the prefrontal cortex but increases activity in the amygdala.
The prefrontal cortex is responsible for higher-order control of our thoughts, behaviours and emotions, and is goal-directed and rational. The amygdala is involved in reflexive and emotional responses. Higher amygdala activity and lower prefrontal cortex activity explains why we are less rational and more emotional and reactive when we are stressed.
There are five types of activities that can help our brains complete the stress cycle. https://www.youtube.com/embed/eD1wliuHxHI?wmode=transparent&start=0 It can help to understand how the brain encounters stress.
1. Exercise – its own complete stress cycle
When we exercise we get a short-term spike in cortisol, followed by a healthy reduction in cortisol and adrenaline.
Exercise also increases endorphins and serotonin, which improve mood. Endorphins cause an elated feeling often called “runner’s high” and have anti-inflammatory effects.
When you exercise, there is more blood flow to the brain and higher activity in the prefrontal cortex. This is why you can often think more clearly after a walk or run. Exercise can be a helpful way to relieve feelings of stress.
Exercise can also increase the volume of the hippocampus. This is linked to better short-term and long-term memory processing, as well as reduced stress, depression and anxiety.
2. Cognitive activities – reduce negative thinking
Overly negative thinking can trigger or extend the stress response. In our 2019 research, we found the relationship between stress and cortisol was stronger in people with more negative thinking.
Higher amygdala activity and less rational thinking when you are stressed can lead to distorted thinking such as focusing on negatives and rigid “black-and-white” thinking.
Activities to reduce negative thinking and promote a more realistic view can reduce the stress response. In clinical settings this is usually called cognitive behaviour therapy.
At home, this could be journalling or writing down worries. This engages the logical and rational parts of our brain and helps us think more realistically. Finding evidence to challenge negative thoughts (“I’ve prepared well for the exam, so I can do my best”) can help to complete the stress cycle.
3. Getting creative – a pathway out of ‘flight or fight’
Creative activities can be art, craft, gardening, cooking or other activities such as doing a puzzle, juggling, music, theatre, dancing or simply being absorbed in enjoyable work.
Such pursuits increase prefrontal cortex activity and promote flow and focus.
Flow is a state of full engagement in an activity you enjoy. It lowers high-stress levels of noradrenaline, the brain’s adrenaline. When you are focussed like this, the brain only processes information relevant to the task and ignores non-relevant information, including stresses.
4. Getting social and releasing feel-good hormones
Talking with someone else, physical affection with a person or pet and laughing can all increase oxytocin. This is a chemical messenger in the brain that increases social bonding and makes us feel connected and safe.
Laughing is also a social activity that activates parts of the limbic system – the part of the brain involved in emotional and behavioural responses. This increases endorphins and serotonin and improves our mood.
5. Self-soothing
Breathing exercises and meditation stimulate the parasympathetic nervous system (which calms down our stress responses so we can “reset”) via the vagus nerves, and reduce cortisol.
A good cry can help too by releasing stress energy and increasing oxytocin and endorphins.
Emotional tears also remove cortisol and the hormone prolactin from the body. Our prior research showed cortisol and prolactin were associated with depression, anxiety and hostility.
Action beats distraction
Whether it’s watching a funny or sad movie, exercising, journalling, gardening or doing a puzzle, there is science behind why you should complete the stress cycle.
Doing at least one positive activity every day can also reduce our baseline stress level and is beneficial for good mental health and wellbeing.
Importantly, chronic stress and burnout can also indicate the need for change, such as in our workplaces. However, not all stressful circumstances can be easily changed. Remember help is always available.
If you have concerns about your stress or health, please talk to a doctor.

We don’t know what you’ve heard, but generally speaking it’s been found to be very beneficial to bones, joints, and skin! We wrote about it quite recently on a “Research Review Monday”:

The Joy of Movement – by Dr. Kelly McGonigal
10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.
We know that exercise is good for us. Obviously. We know that that exercise will make us feel good. In principle.
So why is that exercise bike wearing the laundry instead, or the weights bench gathering dust?
Dr. Kelly McGonigal explores our relationship with exercise, both the formal (organized, planned, exercise that looks like exercise) and the informal (ad hoc, casual, exercise that looks like just having a nice time).
Moreover: she starts with the why, and moves to the how. The trick she plays on us here is to get us very fired up on the many tangible benefits that will make a big difference in all areas of our lives… And then shows us how easy it can be to unlock those, and how we can make it even easier.
And as to making it stick? Exercise can be addictive, and/but it’s one of the few addictions that is almost always healthful rather than deleterious. And, there are tricks we can use to heighten that, thresholds that once we pass, we just keep going.
She also looks at the evolutionary tendency of exercise to be connection-building, as part of a community, friend group, or couple.
And, yes, she gives attention also to undertaking exercise when circumstances aren’t ideal, or our bodies simply won’t allow certain things.
In short: if any book can get you shaking off the cobwebs, this is the one.
