The beginning of this month saw “Blue Monday,” the day coined by PR everywhere as the most miserable day of the year, after a psychologist was actually asked to create a formula to decide “the most depressing day of the year” for a holiday company. This was obviously a PR stunt grown way out of proportion as over 10 years later, we are still talking about the fact there is seemingly only one day in the year where it is okay to feel depressed. From a health perspective, this is both an inaccurate portrayal of the debilitating mental health issues that many deal with daily, and also quite harmful to those struggling with depression.
Depression and mental health are slowly but surely being taken more seriously as a health issue just like any other, and marketing campaigns like Blue Monday will hopefully start to lose traction soon, but it does highlight more serious health concerns of depression and similar mental health problems. Indeed, to counteract the Blue Monday campaigns, the brilliant mental health charity Mind run a #BlueAnyDay hashtag, to remind people of the serious nature of depression.
Blue Monday may be a ridiculous myth that one particular day can make a whole nation depressed simply because of the time of year, but Seasonal Affective Disorder, or SAD, is a particular type of depression which comes and goes with the seasons and is all too real for many people around the world. In this blogpost we are balancing out the notion of Blue Monday by providing you with the symptoms, causes and treatment options for the serious condition of SAD.
SAD is a type of depression thought to affect a part of the brain called the hypothalamus, although there is still a lot to be learnt about the causes and our understanding of this condition. The hypothalamus homes the pituitary gland which controls the release of hormones around the body, and so the hypothalamus regulates many reactions and feelings, such as hunger, thirst, sleep, our body clock and our mood. The most popular theory we have for the cause of SAD, is that light from the sun stimulates our hypothalamus and helps it to understand our circadian rhythm so we know when to feel, for example, hungry or sleepy. Those people with SAD feel the seasonal affects of shorter days and longer nights, and this, combined with other chemical imbalances in the brain such as serotonin and melatonin, again because of the change of seasons and less sunlight, stop the hypothalamus working efficiently, causing many symptoms including a reduced mood and depression in some cases. A small number of people suffer with SAD during Spring and Summer with reduced symptoms in the Fall and Winter, but most people experience Fall and Winter SAD, which is how it gets it’s common and often misunderstood name, ‘the winter blues.’
Although a general decreased mood is the most prominent and well known symptom of SAD, there are many other signs of SAD, because the hypothalamus controls such a lot. Someone with SAD may notice some or all of the following:
Depression can be diagnosed with a psychological examination from your family doctor, where they may ask you questions about your general mood, sleeping patterns and family history of mental health. SAD, however, is slightly more difficult to diagnose, because it is a type of depression and can only really be tracked over several years. If you have experienced depressed feelings at the same time of year for two or more years, then SAD should be considered, especially if at other times of the year there is no depression.
There are many treatment options available to treat depression and SAD, including talking treatments such as therapy and cognitive behavioral therapy (CBT), or antidepressant medication. Some people find light boxes to be a great help in easing the symptoms of SAD, as it exposes the hypothalamus to the light it is missing out on during the winter months. Light boxes contain a much stronger light than those around your house, and can be used in sessions of 20-90 minutes. Some people also favor ‘dawn simulating’ lights which are similar, but work on a timer so that they come on earlier than the dawn in winter to simulate a summertime clock and help regulate the hypothalamus.
SAD is treatable and is now largely accepted as a credible mental health condition, as is depression, so please seek help if you are feeling depressed any time of the year, whether it’s January or June. If you are concerned about any of your symptoms, we suggest putting them all into a symptom checker like Isabel, and taking the results to discuss with your doctor.
