One of the many unresolved mysteries in modern day health care is the infamous “winter depression” or as t science prefers to call it: seasonal affective disorder. Many people experience moodiness during the coldest time of the year and depending on the severity of the case, the disorder can be linked to gaining weight, loss of libido, low energy levels, feelings of melancholy and deep sadness for no obvious reason. Those who are affected by winter depression have trouble getting up in the morning and follow their day to day routines.



Light

Some researchers are convinced that the lack of sunlight is to blame for the winter blues. Studies have shown that people who are prone to this disorder are particularly sensitive to light and after a brief exposure to bright light their symptoms seem to lessen. The main issue is not getting enough light in the morning because the brain interprets darkness as a sign that we should still be in bed and sleeping - hence the general sense of fatigue during the day. Also many people who suffer from seasonal affective disorder are genetically predisposed to depression.

Melatonin

Another cause for the lack of good mood during the cold months could be overproduction of melatonin – the hormone related to sleep. Again – the lack of sunlight leads to imbalance of the natural chemistry of the body and thus the secretion of melatonin is higher than it needs to be. Although the many benefits from the sleep hormone are absolutely undeniable, too much of it can cause issues. Certain studies have linked melatonin to worsening overproduction the symptoms of general depression.



Social isolation

The Christmas holiday is usually a joyful  opportunity for everyone to be with their family and loved ones. But the unpleasant truth for the rest of winter is that due to the cold weather people usually prefer to stay indoors and the time for socializing significantly shortens. The lack of connection and meaningful interaction add even more frustration to those already fighting seasonal affective disorder. Having a satisfying social life is crucially important for maintaining stable mental health.



Vitamin D

Winter is rightfully associated with lack of Vitamin D, which is often called “sunshine vitamin” because it is produced as a result between the contact of skin cells and sunlight. .  Reduced daytime and freezing weather leaves most of people with a risk for deficiency which brings about danger for serious health issues, one of them being winter depression. Many scientists explain seasonal affective disorder with the lack of vitamin D and recommend taking supplements with this vitamin as a form of sufficient cure.  Vitamin D is found in many areas of the brain, including such that are linked to developing depression.



Conclusion

In case you do have seasonal affective disorder and it is preventing you from functioning during the winter, the first thing to remember is that you are not alone. Educate yourself as much as possible about the disorder in general and your personal relationship with it. Don’t forget to meet up with your friends, every time the sun is out – don’t stay indoors and consult a medical professional for further steps.
