brain chemicals

Some of us have brains that are more sensitive to the effects of stress. Researchers are just beginning to uncover the biochemistry behind this differential. The most common forms ofantidepressantstarget the neurotransmitters serotonin and norepinephrine because some research concludes that low levels of these chemical motivators are part of what gets us down. However, only a few people respond well to the most common forms of antidepressants, while others try one drug after another without substantial mood improvement. A recent research study, published earlier this year inAnnals of the National Academy of Sciences,can reveal the reason. Research suggests that differences in the way our brains process a chemical called galanin may make some of us lessresilientand able to recover after difficult experiences.

The weather

Less sun during the winter months can make us sad, and this effect is more pronounced for some people than others. researcherskeller and colleaguesHe studied hundreds of people and discovered that during the spring the mood improved; participants also reported more outdoor activities. We may also be more cognitively flexible and able to think creatively about how to solve our problems in spring compared to winter. A subgroup of people suffer from Seasonal Affective Disorder, a condition in which the winter blues become completelydepressionalong with associated changes in sleep,appetite, mimotivation. Victims are more likely to be women. Exposure to outdoor sunlight also provides us with vitamin D, a substance with clear links to depressed mood.

Vitamin D

Most people in the US have insufficient or deficient levels ofVitamin D.The reasons are not clear, but may be related.nutritionand insufficient sun exposure. People with dark skin are more vulnerable to vitamin D deficiency due to their decreased ability to process vitamin D from sunlight. Vitamin D deficiency has been statistically linked to depression. In a large Dutch study ofHoogendijk and colleagues (2008) of more than 1,200 people age 65 and older, vitamin D levels were 14% lower in people with major or minor depressive disorder compared with those without depressed mood.

hormones

Hormones are substances produced by theendocrineglands that influence many bodily functions, including growth and development, mood,sexualFunction and metabolism. The levels of certain hormones, such as those produced by thethyroid gland, may be factors of depression. Additionally, some symptoms of depression are associated with thyroid conditions. Hormones fluctuate during the menstrual cycle and can create vulnerability to sad or depressed moods both before and during pregnancy.perimenopauseand menopause. There are individual differences in the vulnerability of our moods to the effects of hormones. If you are more vulnerable, you may want to see a doctor to see if medication is needed to help regulate your hormones. you can also tryalternative medicinetreatments, such as acupuncture, to reduce hormone-related mood imbalance.

Expectations

Our moods are not just a function of what happens to us, but also how we view the events in our lives and the meanings we give them. There are phases in most of our lives where it seems like we're working hard and doing all the right things, but we don't see many external rewards coming our way. We may not be paid what we think we're worth, or we may not be able to afford a house, car, or vacation as nice as our friends'. We may have a hard time finding the right partner, while our friends or siblings seem to have no problem finding love. We may have to work harder and harder than our friends to get the same grade on a test or to earn a living. We may experience a difficult separation or loss. Life, naturally, is not fair; periods of struggle, suffering and loss are inevitable. If we expect fair or special treatment all the time or hope that things will never change, we are bound to be disappointed. So if you are feeling down because of recent events, remember that hard times are a part of life and they will pass. You might also try to deliberately broaden your vision and focus on the good parts of your life or experiences you are proud of.

Adverse events in childhood

stressfulLife events can deplete our physical and mental resources, making us more vulnerable to depression and physical illness.A story of childhood trauma., including abuse, poverty, or the loss of a parent, can reset our developing brains to be less cognitively flexible. It seems that our brains naturally go into a "fight, flight, freeze" response to stress or threat, and we often have to use our prefrontal cortex or executive center to get out of that state. prolonged stress onchildhoodit can make our brains less interconnected and resilient; our brains can more easily "get stuck" onnegative thinkingaccentuated patterns or states, making us less able to change lanes.

THE BASICS

  • What is depression?
  • Find a therapist to overcome depression.

stress builds up

As Robert Sapolsky argues in his book,Why don't zebras have ulcers?, our human stress response systems are designed to respond to acute and time-limited stressors that normally require a physical response. When our ancestors were chasing that prowling tiger, they could relax and eat. Stressors in today's world are much more chronic and less capable of being controlled by action, and we often don't have time to recover and reorganize. financial stress,soledad, constant fights with loved ones, bullying, long commutes, academic or job demands, or unemployment can drag on, unleashing a cascade of effects in many areas of our lives. When stress hits us one after another with no time to recover, it can leave us exhausted and despondent, without enough energy to recover.

negative ruminations

You may be feeling depressed because you are sitting around thinking about life's disappointments or trying to find a reason why things are not going your way. Research Studies by Psychologists at the University of MichiganSusan Nolen-Hoeksema and colleaguesPoint out that sitting around thinking about your negative mood or negative events only makes it worse. One negative thought leads to another, and then another, until it is buried under a mountain of negative problems and predictions. This can easily lead to a loss of perspective and motivation, which can interfere with taking action to resolve the problem. If you find yourself in a negative thought cycle, get up immediately and do something pleasant or neutral to occupy your mind. This could be as simple as emptying the dishwasher, rearranging your closet, going for a walk, catching up with a friend, or starting a work project.

Continue drawing yourattentionto the negative and spoil your pleasure when something positive happens by telling yourself "it won't last" or "you don't deserve it."

Soledad

Our human brains are wired to be part of a social group, and we experiencesoledadas chronically stressful and depressing. Sadly, some of us have toxic or neglectful families that don't provide support or presence when we need it. In the same way, we can feel that our friends are moving on, findingromantic relationshipsor have children, for example - and leave us behind. Research using fMRI brain scans shows that even the slightest social rejection turns on the same areas of our brains that physical pain does. Feeling excluded, rejected or left out makes us sad; It can also lead to reflect on our faults, further worsening our state of mind. We become scared of further rejection and isolate ourselves, perpetuating the negative cycle. While there may not be an immediate cure for loneliness, it helps to get out into the world and pursue your natural interests, which can lead to expanding yourred social. Keeping in touch with old friends or family and deliberately looking for opportunities to connect can also help.

final thoughts

The reasons for a depressed mood are often multifaceted and can be difficult to determine. If you feel depressed for two weeks or more, see a doctor to rule out or treat underlying biological factors. Consider seeing a mental health professional to help you manage stress and expectations, negotiate life changes, or deal with emotional fallout from the past.traumasand dysfunctional families. if you can't paytherapy, antidepressants can still help change the underlying biology. Exercising outdoors can provide sunlight and lift your spirits. Develop a toolkit of stress-reducing activities, such as regular exercise, yoga, ormeditation, watch funny movies, play team sports, do something creative or innovative, and go out and/or confide in supportive friends.
