Day 30 : 12 surprising reasons for depression

1. Summer weather
I knew about winter could somehow associated with depression, which is so called as Seasonal Affective Disorder (SAD). But according to Afred Lewy (MD, professor of psychiatry at Oregon Health and Science University in Portland), less than 1 percent of people experience the depression in the summer. It is because the body has a hard time to adjust the time for waking and sleeping which is related with the imbalance of the hormone melatonin.

2. Smoking
Smoking can over-activate the "brain reward system". It results in higher level of dopamine and serotonin (which is also the mechanism of action for antidepressant drugs) and causes addictive effect. When someone stops smoking, the mood swings and depression arises.

3. Thyroid disease
One of the function of thyroid hormone is acting as a neurotransmitter and regulate serotonin levels. Therefore, hypothyroidism with lacking of thyroid hormone causes depression.

4. Poor sleeping habit
It is logic. If you don't sleep, you don't have enough time to replenish the brain cells, the brain acts slower or couldn't functioning well, and it could lead to depression.

5. Facebook overload
Spending too much time in artificial social-networking is one of the reason for depression. You might most probably had been experienced it and it didn't feel good at all.

6. End of a TV show or movie
In 2009, some "Avatar" fans was reported to suicidal because they felt depressed when realizing the movie's fictional world wasn't real. There was similar happening to the final installments of the Harry Potter movies.

It doesn't mean that a movie or TV series is bad for mental health. Depression could only arose if someone watching the TV shows primarily for companionship. They were "swept up in a narrative forgetting about real life and their own problems".

7. Where you live
Living in urban seetings do have higher risk of mood disorders than those in rural regions. It is reasonable, people living in urban area are being more stress and most likely have to bear with the bad traffic condition, competitive job tasks, and more complicated relationship.

8. Too many choices
It is linked to perfectionist who exhaustively reviewing their options in the search for the very best item.

9. Lack of fish in the diet
Low intake of omega-3 fatty acids, found in salmon and vegetable oils, may be associated with a greater risk of depression. A 2004 Finnish study found an association between eating less fish and depression in women, but not in men.

10. Poor siblings relationship
It is obvious that if you couldn't get well with the people that close to you, you may feel depress.

11. Birth control pill
Oral contraceptives contain a synthetic version of progesterone, which studies suggest can lead to depression in some women.

12. Rx medication
Depression is a side effect of many medications. For example, Accutane and its generic version (isotretinoin) are prescribed to clear up severe acne, but depression and suicidal thoughts are a potential risk for some people.

Depression is a possible side effect for anxiety and insomnia drugs, including Valium and Xanax; Lopressor, prescribed to treat high blood pressure; cholesterol-lowering drugs including Lipitor; and Premarin for menopausal symptoms.
