Countless parents across the country recently dropped their kids off at college for the first time. This transition can stir a whirlwind of feelings: the heartache of parting, sadness over a permanently changed family dynamic, the uncertainty of what lies ahead – but also the pride of seeing your child move toward independence. Some might describe the goodbye as bittersweet, or say that they’re feeling mixed emotions.

In that scenario, what would you do if I asked you to rate how you felt on a scale from 1-9, with 1 being the most negative and 9 the most positive? This question seems silly given the circumstances – how should you rate this blend of bad and good? Yet, this scale is what psychology researchers often use to survey feelings in scientific studies, treating emotions as either positive or negative, but never both.

I’m a neuroscientist who studies how mixed emotions are represented in the brain. Do people ever truly feel both positive and negative at the same time? Or do we just switch quickly back and forth?

What emotions do for you

Scientists sometimes define emotions as states of the brain and body that motivate you toward or away from things. People typically experience them as either positive or negative.

If you’re walking in the woods and see a bear, your heart rate and breathing accelerate, giving you the urge to flee – likely helping you make a decision that keeps you alive. Many scientists would label that reaction as the emotion of “fear.”

Similarly, warm feelings around loved ones make you want to stay around them and nurture those relationships, helping strengthen your social network and support system.

This approach-and-avoid view of emotions helps explain why emotions evolved and how they affect decision-making. Scientists have used it as a guiding principle when trying to figure out the biology behind emotions.

But mixed emotions do not fit into this framework. If opposite biological systems inhibit each other, and if emotions are biological, you can’t experience opposites in the same moment. This reasoning would mean it’s impossible to hold two opposite emotions at once; you must instead be flipping back and forth. Ever since scientists proposed the first theories on the biological foundations of emotion, this is how they’ve conceptualized mixed emotions.

Untangling the biology of mixed emotions

Mainstream methods for measuring feelings still treat positive and negative as opposite sides of a spectrum. But researchers find that study participants commonly report mixed emotions.

For instance, people across cultures experience some feelings, such as nostalgia and awe, as simultaneously positive and negative.

One research group found that volunteers’ physiological responses – such as heart rate and skin conductance – display unique patterns during experiences that are both disgusting and funny, compared with either category separately. This implies that disgusted and amused reactions are indeed occurring simultaneously to create something new.

In a seemingly contradictory finding, research that used functional magnetic resonance imaging, or fMRI, to study brain responses to disgusting humor did not find a pattern of brain activity that was distinct from plain disgust. The brain states of people reporting being both disgusted and amused seemed to reflect only disgust – not a unique pattern for a new mixed emotion.

But fMRI studies generally rely on averaging brain activity across people and time. The heart of the question – experiencing truly mixed emotions versus fluctuating between positive and negative states – concerns what the brain is doing over time. It is possible that by looking at the average brain activity across time, scientists end up with a pattern that looks a lot like one emotion – in this case, disgust – but are missing important information about how activity changes or stays the same second-to-second.

Mixed emotions in the brain

To dig in to that possibility, I ran a study to see whether mixed emotions were related to a unique brain state that held steady over time.

While in the MRI machine, participants watched a bittersweet animated short film about a young girl’s lifelong pursuit, with her father’s support, to become an astronaut. Spoiler alert: Her dad dies. After scanning, those same subjects rewatched the video and labeled the exact times they had felt positive, negative and mixed emotions.

My colleagues and I discovered that mixed emotions didn’t show unique, consistent patterns in deeper brain areas like the amygdala, which plays an important role in quick responses to emotionally important items. Strikingly, the insular cortex, a part of the brain that connects deeper brain regions with the cortex, had consistent and unique patterns for both positive and negative emotions, but not for mixed ones. We took this finding to mean that regions such as the amygdala and insular cortex were processing positive and negative emotions as mutually exclusive.

But we did see unique, consistent patterns in cortical regions such as the anterior cingulate, which plays an important role in processing conflict and uncertainty, and the ventromedial prefrontal cortex, which is important for self-regulation and complex thinking.

These brain regions in the cortex that carry out more advanced functions appear to represent much more complex states, allowing someone to truly feel a mixed emotion. Brain regions such as the anterior cingulate and ventromedial prefrontal cortex integrate many sources of information – essential for being able to form a mixed emotion.

Our findings also fit with what scientists know about brain and emotional development. Interestingly, kids do not begin to understand or report mixed emotions until later in childhood. This timeline matches up with what researchers know about how development of these brain regions leads to more advanced emotional regulation and understanding.

What happens next

This study revealed something new about how complex feelings are formed in the brain, but there is much more to learn.

Mixed emotions are so interesting, in part, because of their potential role during important life events. Sometimes, mixed emotions help you cope with big changes and turn into cherished memories. For example, you may experience both positive and negative feelings when your friends throw a big going away party before you move to another city for your dream job.

Other times, mixed emotions are an ongoing source of distress. Even if you know you should break up with a romantic partner, that doesn’t mean all the positive feelings you have about them automatically go away, or that a split won’t bring some pain.

What leads to this difference in outcome? Might these differences have to do with how the brain represents these mixed emotional states over time? A better understanding of mixed emotions might help people make sure these kinds of strong feelings become cherished memories that help them grow, instead of a distressing goodbye they fail to get over. https://www.youtube.com/embed/IoVbd_dZYMk?wmode=transparent&start=0 Mixed feelings elicited unique neural activity in particular areas of the brain.

Have you ever taken a personality test? If you’re like me, you’ve consulted BuzzFeed and you know exactly which Taylor Swift song “perfectly matches your vibe.”

It might be obvious that internet quizzes are not scientific, but many of the seemingly serious personality tests used to guide educational and career choices are also not supported by research. Despite being a billion-dollar industry, commercial personality testing used by schools and corporations to funnel people into their ideal roles do not predict career success.

Beyond their lack of scientific support, the most popular approaches to understanding personality are problematic because they assume your traits are static – that is, you’re stuck with the personality you’re born with. But modern personality science studies find that traits can and do change over time.

In addition to watching my own personality change over time from messy and lazy to off the charts in conscientiousness, I’m also a personality change researcher and clinical psychologist. My research confirms what I saw in my own development and in my patients: People can intentionally shape the traits they need to be successful in the lives they want. That’s contrary to the popular belief that your personality type places you in a box, dictating that you choose partners, activities and careers according to your traits.

What personality is and isn’t

According to psychologists, personality is your characteristic way of thinking, feeling and behaving.

Are you a person who tends to think about situations in your life more pessimistically, or are you a glass-half-full kind of person?

Do you tend to get angry when someone cuts you off in traffic, or are you more likely to give them the benefit of the doubt – maybe they’re rushing to the hospital?

Do you wait until the last minute to complete tasks, or do you plan ahead?

You can think of personality as a collection of labels that summarize your responses to questions like these. Depending on your answers, you might be labeled as optimistic, empathetic or dependable.

Research suggests that all these descriptive labels can be summarized into five overarching traits – what psychologists creatively refer to as the “Big Five.”

As early as the 1930s, psychologists literally combed through a dictionary to pull out all the words that describe human nature and sorted them in categories with similar themes. For example, they grouped words like “kind,” “thoughtful” and “friendly” together. They found that thousands of words could be accounted for by sorting them between five traits: neuroticism, extroversion, conscientiousness, agreeableness and openness.

What personality is not: People often feel protective about their personality – you may view it as the core of who you are. According to scientific definitions, however, personality is not your likes, dislikes or preferences. It’s not your sense of humor. It’s not your values or what you think is important in life.

In other words, shifting your Big Five traits does not change the core of who you are. It simply means learning to respond to situations in life with different thoughts, feelings and behaviors.

Can you change your personality?

Can personality change? Remember, personality is a person’s characteristic way of thinking, feeling and behaving. And while it might sound hard to change personality, people change how they think, feel and behave all the time.

Suppose you’re not super dependable. If you start to think “being on time shows others that I respect them,” begin to feel pride when you arrive to brunch before your friends, and engage in new behaviors that increase your timeliness – such as getting up with an alarm, setting appointment reminders and so on – you are embodying the characteristics of a reliable person. If you maintain these changes to your thinking, emotions and behaviors over time – voila! – you are reliable. Personality: changed.

Data confirms this idea. In general, personality changes across a person’s life span. As people age, they tend to experience fewer negative emotions and more positive ones, are more conscientious, place greater emphasis on positive relationships and are less judgmental of others.

There is variability here, though. Some people change a lot and some people hold pretty steady. Moreover, studies, including my own, that test whether personality interventions change traits over time find that people can speed up the process of personality change by making intentional tweaks to their thinking and behavior. These tweaks can lead to meaningful change in less than 20 weeks, instead of 20 years.

Cultivating personality traits that serve you best

The good news is that these cognitive-behavioral techniques are relatively simple, and you don’t need to visit a therapist if that’s not something you’re into.

The first component involves changing your thinking patterns – this is the cognitive piece. You need to become aware of your thoughts to determine whether they’re keeping you stuck acting in line with a particular trait. For example, if you find yourself thinking “people are only looking out for themselves,” you are likely to act defensively around others.

The behavioral component involves becoming aware of your current action tendencies and testing out new responses. If you are defensive around other people, they will probably respond negatively to you. When they withdraw or snap at you, for example, it then confirms your belief that you can’t trust others. By contrast, if you try behaving more openly – perhaps sharing with a co-worker that you’re struggling with a task – you have the opportunity to see whether that changes the way others act toward you.

These cognitive-behavioral strategies are so effective for nudging personality because personality is simply your characteristic way of thinking and behaving. Consistently making changes to your perspective and actions can lead to lasting habits that ultimately result in crafting the personality you desire.

(Family Features) Although cold weather isn’t directly to blame when you get sick, it creates an environment that makes it easier for germs and illnesses to thrive. In fact, understanding how cooler temperatures affect your chances of getting sick may be your best approach for preventive care.

Despite the old adage that “you’ll catch your death of cold,” the cold itself doesn’t cause illness. More accurately, the cold is more hospitable to viruses, making it easier for them to spread. While you can’t control Mother Nature, you can take steps to protect your health when temperatures drop.

Protect Your Immune System
A weakened immune system makes it harder for your body to ward off intrusive germs. If you’re otherwise healthy, protecting your immune system can be as simple as stepping up typical healthy habits, like eating plenty of nutrient-rich produce, getting enough sleep and exercising. Managing stress and limiting alcohol consumption are also helpful in managing your body’s immune response.

If your immune system is compromised by an underlying condition, it’s a good idea to talk with your doctor about what you can do to add an extra layer of protection during the cooler months, including any vaccines that may help boost immunity.

Combat Congestion
Cool, dry conditions can wreak havoc on your nasal passages, drying them out and reducing the protective layer of mucus that helps fight infection. Sinus pressure and congestion are often some of the first warning signs you’re coming down with something.

To treat your congestion symptoms, you can use a non-medicated option like Mucinex Sinus Saline Nasal Spray. This is the first-ever saline product with a nozzle that lets you switch between two spray pressures. The “gentle mist” helps clear everyday congestion and soothes the nose while the “power jet” helps clear tough nasal congestion often associated with colds. An added benefit is that the product can be used for children 2 years of age and older on the gentle mist setting and children 6 years of age and older on the power jet mode.

Spend Time Outdoors
People naturally spend more time indoors when temperatures drop, but there are some benefits to getting outdoors. One is the natural exposure to vitamin D. Sunlight is a natural source of this important vitamin, which plays a pivotal role in immunity. Sunlight also triggers the body to produce serotonin, which boosts your mood, and multiple studies show a strong correlation between mental and physical health.

Fresh air and exercise are also good for your overall health, and exposure to daylight can help keep your circadian rhythms regulated, which in turn promotes better sleep. What’s more, acute exposure to cold can trigger your body to produce infection-fighting cells, so you’re less prone to illness.

Practice Good Hygiene
It may seem overly simple, but the everyday act of washing your hands can play a big role in preventing illness, especially after you spend time in public places. While out and about, you likely come in contact with many surfaces others may have touched, including door handles, shopping carts, touch screens and menus.

Washing your hands frequently can help prevent you from transferring germs to your body when you touch your eyes, mouth or nose. Also make a habit of wiping down surfaces you touch frequently, such as your keyboard and phone, with disinfectant wipes.

Stay Hydrated
Keeping your body well-hydrated throughout the day can help ensure all your body’s systems are functioning as they should. If you’re dehydrated, your body can’t use the nutrients you consume properly, which affects your immunity. In addition, drinking plenty of water helps flush toxins out of the body before they can cause an infection.

How to Relieve Nasal Congestion

Normally your sinuses are empty except for a thin layer of mucus. When you’re exposed to irritating triggers, like bacteria, a cold or flu virus, allergies or environmental triggers like tobacco smoke and dry air, your body responds by mounting an immune response.

The delicate tissues lining your sinuses start to swell, and this, in turn, puts pressure on the underlying tissues in your face, causing painful sinus pressure.

You can relieve sinus pressure symptoms in several different ways, including:

• Using a humidifier or vaporizer.
• Taking a long, hot shower; it may have the same effect as using a humidifier if one is not available.
• Drinking plenty of fluids.
• Using a warm compress on your face; resting a warm towel over your sinuses may provide relief.
• Irrigating your sinuses. Using a neti pot; saline nasal spray, such as Mucinex Sinus Saline Nasal Spray; or syringe with salt water may help flush debris from your sinuses to relieve sinus congestion.
• Sleeping with your head elevated.

If these steps don’t work, the next approach is typically over-the-counter medicine. When trying to relieve sinus pressure and nasal congestion, look for a decongestant. A decongestant can help shrink mucus membranes that have swollen in your sinuses, allowing the trapped mucus to drain.
