How a healthy sex life can help minimize depression and anxiety symptoms
When you struggle with anxiety or depression, sex may be the last thing on your mind. But understanding the physiological and mental benefits of a healthy sex life can help it become a tool for well-being.
- The physiological responses our bodies have to sex can minimize the symptoms of anxiety and depression.
- Deficiencies in nitric oxide are associated with irritability, depression, anxiety, insomnia, and less energy. Having sex increases your body's nitric oxide levels.
- Sex also increases epinephrine, oxytocin, dopamine and serotonin, all of which are linked to mood, behavior, and well-being.
Depression can steal your sex drive and leave you feeling the deepest kind of lonely. And yet, sex can not only make you feel connected to another person, but the physical and biological responses our bodies have to sex can actually minimize some of the symptoms of depression.
And then there's anxiety. When you're suffering from anxiety, you feel cornered, lost and stuck; not able to take any steps forward. Sex is the last thing on your mind… and yet again—the physical and biological responses our bodies have to sex can minimize those symptoms, too.
Sex might not be a cure-all (wouldn't it be amazing if it was?) but there is a lot of evidence to prove that sex can have a positive impact on your state of mind, as well as your physical and mental health.
What happens in our bodies during sex

To explain this in more detail, let's talk about what biologically happens within our bodies when we are aroused and have sexual intercourse. This process begins before you have sex (and continues for a while after you have an orgasm), which is how having a healthy sex life can affect your moods, behaviors, and thoughts.
Arousal provokes activity in the “emotions” area of our brains
MRI studies have shown that the first thing to happen when we are aroused is that there is an increase in activity to the part of the brain that controls your emotions—this is called the limbic system.
During this initial arousal stage, a few physical things happen, as well: our blood pressure and blood flow increases, sensitive areas of our body (such as the genitals and breasts) become tender and our hearts beat faster. In general, arousal acts like an "on" switch for our bodies to prepare us for intercourse.
Sexual intercourse increases our nitric oxide activity, which impacts our anxiety and depression levels
When it comes to having intercourse, there are many complex things happening in our bodies and brains all at once. Along with the increased blood flow that happens when we're aroused, there is also a surge of nitric oxide released in our bodies while we have sex.
Nitric oxide molecules are essential in terms of our blood vessel health because these molecules relax the inner muscles of the blood vessels, which then causes those vessels to widen. This surge in nitric oxide explains why some areas of our bodies are tender during arousal and intercourse, and why our skin may become flushed when we are aroused.
It's important to note that some of the side effects of nitric oxide deficiency (which you can read more about here) are irritability, depression, anxiety, insomnia, and less energy.
People who struggle with nitric oxide deficiency often experience symptoms of anxiety and depression—and the reverse is also true: people who have an influx of nitric oxide (let's say, by having sex) can minimize their symptoms of depression and anxiety.
Sexual intercourse releases dopamine and serotonin, the “balancing chemicals” in our brains

An influx in nitric oxide isn't the only thing that happens in our bodies when we have sex.
Having sexual intercourse releases some other messages from our brain to our body, as well. These messages are called neurotransmitters.
Dopamine is one of those neurotransmitters, and it plays a huge role in how we feel pleasure. Not only that, but dopamine also plays a role in motivating our brains to feel that pleasure again.
When we have sex, our bodies spread the dopamine chemical along the various major pathways of our brains. This happens during many other pleasurable activities (not just sex), and like a car that's running smoothly until it isn't, you likely won't notice your body is doing this unless there is a problem with how your body carries out that function.
Anyone who has struggled with this affliction can tell you that motivation and incentive are extremely difficult to find when you're experiencing depression.
Now, let's talk about serotonin because there is also an influx in serotonin when we have intercourse. Serotonin and dopamine affect many of the same things in our bodies, just in different ways. Both are equally important in regulating various bodily functions like sleep, emotions, and metabolism.
Researchers have been studying and analyzing the link between serotonin and depression for half a century now and while it was originally believed to be as simple as "low serotonin causes depression", the reality is far more complex.
In simple terms, low serotonin isn't a direct cause of clinical depression (as there isn't just one cause and they are extremely difficult to pinpoint due to our complex systems). However, raising your serotonin levels has proven to be one of the most effective depression treatments.
Why? Because serotonin is known to help regulate your mood, social behaviors, emotions, appetite and digestion, sleep, memory and sex drive. Some of the more prominent symptoms of anxiety and depression include erratic sleep, bad memory, hard-to-manage emotions and mood swings that alter your social behavior.
Taking this information into account, it makes total sense that regulating some of these body functions (by having regular sex and releasing these hormone-balancing chemicals) would help decrease the symptoms of these specific mental health concerns.
Sexual intercourse, epinephrine and the “feeling alive” sensation
We also have to talk about the epinephrine chemical that is released during sexual intercourse. Epinephrine is an adrenaline hormone. This hormone activates our sympathetic nervous system, which makes you feel that "heart pounding in your chest" kind of exhilaration you feel when you're out for a jog, getting a new tattoo or (you guessed it) having sex.
According to Medical News Today, low levels of epinephrine can often result in physical and mental symptoms such as feeling anxious or depressed.
The 2 big “O”s
The "O"s are "orgasm" and "oxytocin". Orgasms, you (hopefully) have when you have sexual intercourse. Oxytocin is the hormone that is released during orgasm.
Known as the 'love hormone', oxytocin is that "let's be together forever" feeling that plays a vital role in our pleasurable climaxes as well as how our body feels after we've reached climax. You get a big dose of oxytocin during an orgasm, but that's not the only time oxytocin makes an appearance. For women, oxytocin is also released during labor and while breastfeeding, which helps create that motherly bond between herself and her newborn baby.
See, oxytocin doesn't just make you feel good, and it's not just about feeling "in love"—but when our bodies experience surges in oxytocin we also begin to feel attachment and trust as a result of this hormone surge.
According to PET scans taken at the moment of orgasm, the reward circuits in our brains light up like fireworks and the center of reasoning and behavior temporarily shut down as you spiral into what can only be described as sexual bliss. You can see a really cool video by Rutgers University of said sexual fireworks shown in the female brain below.
Knowing what we know about anxiety disorders and how easily things are overthought to the point of bringing on a panic attack, that temporary shut off of reasoning can be incredibly helpful for someone who is feeling "stuck" in their own mind.
Given the link between orgasm and oxytocin (and the link between oxytocin and feeling good), it's not a far leap to consider the effect oxytocin released by sex can have on someone who is struggling with an anxiety or depression disorder.
A new study explores how the brain encodes different scents — a topic which scientists know relatively little about, compared to our other senses.
- Unlike sight and hearing, our sense of smell remains poorly understood.
- In a new study, scientists used machine learning to categorize thousands of different odors, based on chemical properties.
- By exposing mice to odors and measuring their neural activity, the scientists found that the brain more closely groups together odors that are chemically similar.

Pashkovski et al.<p style="margin-left: 20px;"><br></p><p>To investigate, the researchers created a database of thousands of odorous chemical structures, and they used machine learning to categorize them by features such as number of atoms, molecular weight and electrochemical properties. These odors were separated into three categories: high diversity, intermediate diversity and low diversity.</p><p>Then the researchers exposed different odors to mice, and used multiphoton microscopy to record neural activity in the piriform cortex and olfactory bulb. The results showed that when odors are chemically similar, so too is neural activity. In other words, the cortex emphasizes relationships between chemically similar odors, and it creates groupings for similar odors, which helps us distinguish between objects in the world. </p>
Smell and neuroplasticity<p>The results also suggest that perception of smell is flexible. For example, the team repeatedly exposed mice to a combination of two chemically dissimilar odors. Over time, images showed that the neural patterns produced by the pair of odors become more strongly correlated.</p><p style="margin-left: 20px;">"We presented two odors as if they're from the same source and observed that the brain can rearrange itself to reflect passive olfactory experiences," Datta said. "The plasticity of the cortex may help explain why smell is on one hand invariant between individuals, and yet customizable depending on our unique experiences."</p>
Pixabay<p>The study provides some of the first information on how the olfactory cortex maps different odors. And the results also suggest that, by better understanding the chemical structure of different odors and how that mapping process works, scientists may someday be able to better control our sense of smell.</p><p style="margin-left: 20px;">"We don't fully understand how chemistries translate to perception yet," Datta said. "There's no computer algorithm or machine that will take a chemical structure and tell us what that chemical will smell like. To actually build that machine and to be able to someday create a controllable, virtual olfactory world for a person, we need to understand how the brain encodes information about smells. We hope our findings are a step down that path."</p>
Frequent shopping for single items adds to our carbon footprint.
- A new study shows e-commerce sites like Amazon leave larger greenhouse gas footprints than retail stores.
- Ordering online from retail stores has an even smaller footprint than going to the store yourself.
- Greening efforts by major e-commerce sites won't curb wasteful consumer habits. Consolidating online orders can make a difference.

This is especially relevant to the "last mile" GHG footprint: the distance between the distribution center and the consumer.</p><p>Interestingly, the smallest GHG footprint occurs when you order directly from a physical store—even smaller than going there yourself. Pure players, such as Amazon, are the greatest offenders. Variables like geographic location matter; the team looked at shopping in the UK, the US, China, and the Netherlands. </p><p>Sadegh Shahmohammadi, a PhD student at the Netherlands' Radboud University and corresponding author of the paper, <a href="https://www.cnn.com/2020/02/26/tech/greenhouse-gas-emissions-retail/index.html" target="_blank">says</a> the above "pattern holds true in countries where people mostly drive. It really depends on the country and consumer behavior there."</p><p>The researchers write that this year-and-a-half long study pushes back on previous research that claims online shopping to be better in terms of GHG footprints.</p><p style="margin-left: 20px;">"They have, however, compared the GHG emissions per shopping event and did not consider the link between the retail channels and the basket size, which leads to a different conclusion than that of the current study."</p><p>Online retail is where convenience trumps environment: people tend to order one item at a time when shopping on pure player sites, whereas they stock up on multiple items when visiting a store. Consumers will sometimes order a number of separate items over the course of a week rather than making one trip to purchase everything they need. </p><p>While greening efforts by online retailers are important, until a shift in consumer attitude changes, the current carbon footprint will be a hard obstacle to overcome. Amazon is trying to have it both ways—carbon-free and convenience addicted—and the math isn't adding up. If you need to order things, do it online, but try to consolidate your purchases as much as possible.</p><p>--</p><p><em>Stay in touch with Derek on <a href="http://www.twitter.com/derekberes" target="_blank">Twitter</a>, <a href="https://www.facebook.com/DerekBeresdotcom" target="_blank">Facebook</a> and <a href="https://derekberes.substack.com/" target="_blank">Substack</a>.

Chronic irregular sleep in children was associated with psychotic experiences in adolescence, according to a recent study out of the University of Birmingham's School of Psychology.

The study followed the children for more than 13 years. During that time, mothers filled out questionnaires asking about the children's lives. Factors looked at included housing, parenting, nutrition, physical health, mental wellbeing, environmental exposures, and so on. </p><p>The cohort study inquired about sleep routines, sleep duration, and awakening frequency when the children were 6, 18, and 30 months old, and then again at 3.5, 4.8, and 5.8 years. It also assessed mental health in adolescence using semi-structured interviews, such as the Psychosis-Like Symptom Interview.</p><p>"We know that adolescence is a key developmental period to study the onset of many mental disorders, including psychosis or BPD. This is because of particular brain and hormonal changes which occur at this stage," <a href="https://www.birmingham.ac.uk/staff/profiles/psychology/marwaha-steven.aspx" target="_blank">Steven Marwaha</a>, professor of psychiatry at Birmingham and senior author on the study, <a href="https://www.sciencedaily.com/releases/2020/07/200701125431.htm" target="_blank">said in a release</a>. "Sleep may be one of the most important underlying factors—and it's one that we can influence with effective, early interventions, so it's important that we understand these links."</p><p>After compiling the data, the researchers discovered an association between children with irregular sleeping patterns and teenagers with <a href="https://www.mind.org.uk/information-support/types-of-mental-health-problems/psychosis/about-psychosis/" target="_blank">psychotic experiences</a>—that is, episodes when the person perceives reality differently than those around them. Even when depression at 10 years old was considered as a mediating factor, their findings still suggested "a specific pathway between these childhood sleep problems and adolescent psychotic experiences." </p><p>Toddlers with shorter nighttime sleep duration and late bedtimes were likewise associated with a <a href="https://www.nimh.nih.gov/health/topics/borderline-personality-disorder/index.shtml" target="_blank">borderline personality disorder</a>—a disorder marked by a pattern of varying moods, self-images, and behaviors—in their teenage years. Depression at age 10 did not mediate this particular association, suggesting a separate and more specific pathway. </p>
A more restful tomorrow<p>While the sample size was large and mental health was assessed with a validated interview, there nevertheless remain limitations to this data. For starters, sleep habits were based on mothers' reports. Because they came from memory, versus a more direct observation method such as actigraphy, these data may be prone to imperfect recollection and reporting error. There are also many confounders that could be secretly nudging the results, such as family conditions, prenatal medicines, and a host of environmental factors. Finally, <a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6024884/#:~:text=Sleep%20difficulties%20in%20youth%20with,fear%20of%20dark%20%5B13%5D." target="_blank">the relationship between sleep problems and mental disorders</a> is both complex and two-way.</p><p>As such, the study shows an association between poor childhood sleep later mental disorders but does not prove a causal link. Parents need not worry that a string of nightmares or the eternal struggle settle into bed will be the first ingredients in a witches' brew of debilitating mental disorders. The goal of the study, the researchers point out, is not to create undue worry but improve our ability to recognize the signs of at-risk children and deliver necessary interventions earlier.</p><p>"The results of this study could have important implications for helping practitioners identify children who might be at higher risk for psychotic experiences or BPD symptoms in adolescence, and potentially lead to the design of more effectively targeted sleep or psychological interventions to prevent the onset or attenuate these mental disorders," Isabel Morales-Muñoz, the study's lead researcher, <a href="https://www.healio.com/news/psychiatry/20200702/childhood-sleep-problems-linked-to-adolescent-psychosis-borderline-personality-disorder#:~:text=Sleep%20problems%20during%20early%20childhood,study%20published%20in%20JAMA%20Psychiatry." target="_blank">told Healio Psychiatry</a><u>.</u></p><p>If a parent reading this is worried that their child's sleep patterns are deleterious, the take away should not be despair over an unyielding fate. It should be to seek professional help as soon as possible to begin improving sleep duration and quality. Even if you aren't worried, it's worth remembering that childhood experiences lay the foundation for a lifetime of salubrious sleeping habits. It's so much more than beauty rest.</p>
