Symptoms associated with Seasonal Affective Disorder

There are a number of symptoms that can be a result of Seasonal Affective Disorder which can differ between sufferers so initial diagnosis or even awareness may not always be easy to identify.  Due to this it is ideal to be aware of the possible symptoms if you feel that you or even someone you know may be affected by the condition.

Some of the more common symptoms that those who are affected by SAD suffer from are feelings associated with depression such as despair, feeling low, increased levels of anxiety and being irritable towards people and situations for no discernible reason, but there are others to be aware of as well.

In addition to the psychological symptoms of Seasonal Affective Disorder that are associated with general depression; sometimes referred to as the ‘Winter Blues’ there are also physical symptoms that can be debilitating if not addressed.  Due to the cause of SAD being not receiving enough sunlight to maintain a normal circadian rhythm because of a lack of serotonin sleep problems are common so nights are likely to be restless which in turn can lead towards lethargy and tiredness during the day.  Other SAD symptoms may include cravings for food with carbohydrates and sugar which can lead to weight gain, plus a loss of libido and any physical contact are also potential symptoms as well.

If any of these symptoms sound familiar then it is important to consult with a medical advisor to establish a diagnosis as even when Seasonal Affective Disorder may be assumed they can also indicate other conditions as well.


  1. About 4 years ago I had a fast growing cataract removed from my left eye. Unbeknown to me the surgeon who implanted a replacement intraocular lens used one that had a blue light filter (without my knowledge…apparently they can just chose to do this themselves). I have had a lot of issues in Autumn and Winter since then. Not only is the eye sight as clear on these dull overcast days but I get quite down. As people age their natural lenses become naturally ‘yellow’…this yellowing of the natural lens filters blue light and there is some research (Mainster) that indicates this is causing older people to have some depression and sleep issues. I wanted to warn people who may need to have their natural lens replaced to make sure their surgeons do not chose a lens with a blue light filter. A person can always wear sunglasses to block out harmful afternoon blue light in summer but at least they can take these sunglasses off…if you have a tint on an implanted lens you cannot take it off!

  2. Apologies there was a typing error in my comment…..I meant to say not only is my eyesight not as clear on dull overcast days (when we are mostly requiring blue light) I also get quite down now during Autumn and Winter.
