Despite what you may think, SAD (seasonal affective disorder) is a real thing, and scientist now know the cause
Despite what they have told you, this occurs on a yearly basis. It’s not made up! People from across the globe find themselves suddenly feeling severely depressed. There is nothing coincidental about this. SAD (seasonal affective disorder) is a chemical disorder that is very real. Scientists have been baffled by it for many years, but now the puzzle might have been figured out by some new research.
Some factors make your more susceptible to SAD than other people
- Being female. While the symptoms may be more severe in men, women are diagnosed with SAD more often.
- Age.Winter SAD occurs less in older adults and more in young people.
- Family history. People who have blood relatives that suffer from SAD or any other form of depression are more likely to suffer from SAD.
- Having bipolar disorder or clinical depression. If you suffer from any of these conditions, they may worsen your symptoms of depression.
- Living far from the equator. For people who live far south or far north of the equator, SAD seems more common.
The exact cause of SAD used to be a mystery, but now that mystery has been solved
People used to blame lack of sun exposure during the winters months that were dark for causing SAD. Those who sold lamps and supplements of vitamin D benefited the most from this promoting this belief. Now a study has shown that there is more to it.
Even though a deficiency in vitamin D can cause fatigue and can contribute to irritable mood, the true neurochemical cause has been announced by the University of Copenhagen’s researchers.
Researchers say SAD is caused by a dial in your brain that adjusts serotonin to changing seasons
Brenda Mc Mahon, the lead researcher, explains:
“The serotonin transporter (SERT) carries serotonin back into the nerve cells where it is not active, so the higher the SERT activity the lower the activity of serotonin.” She continued, “Sunlight keeps this setting naturally low, but when the nights grow longer during the autumn, the SERT levels increase, resulting in diminishing active serotonin levels. Many individuals are not really affected by SAD, and we have found that these people don’t have this increase in SERT activity, so their active serotonin levels remain high throughout the winter.”
Scientists have now discovered that to regulate SERT activity You need more melatonin in your system.
