Seasonal Affective Disorder: Treatment & Depression Causes

Understanding Seasonal Affective Disorder

In the area of psychology, various phenomena influence human behaviour and emotions, and one of these is Seasonal Affective Disorder or SAD. This disorder is prevalent and impacts a significant number of individuals globally.

Seasonal Affective Disorder (SAD): A type of depression that's related to changes in seasons — SAD begins and ends at about the same times every year.

What is Seasonal Affective Disorder?

Seasonal Affective Disorder, often abbreviated as SAD, is a type of depression that changes with the seasons. Mainly, symptoms start in the late fall and early winter and go away during the spring and summer. It's often referred to as 'winter depression'. It's less common to have symptoms occur during spring and early summer, but this does happen.

A deep dive into the science behind SAD reveals that this condition may be related to changes in your body's internal clock or circadian rhythm that occur due to decreased sunlight during the fall and winter months. This disruption leads to feelings of depression, amongst other symptoms.

Feeling depressed nearly every day
Low energy
Problems with sleeping
Difficulty concentrating

The Connection between Depression and Seasonal Affective Disorder

All forms of depression, including SAD, involve periods of feeling low, but what distinguishes SAD is the clear seasonal pattern it follows.

For instance, a person may generally feel in good spirits throughout the year, but with the onset of winter, they may become lethargic, lose interest in activities they would typically enjoy and generally feel low - a clear sign of Seasonal Affective Disorder.

This table illustrates the shared and unique characteristics of depression and Seasonal Affective Disorder.

	Depression	Seasonal Affective Disorder
Symptoms	Persistent feeling of sadness	Depression that begins and ends with the seasons
Sleep patterns	No significant change	Increased sleep during the affected season

Therefore, Seasonal Affective Disorder is essentially a subtype of depression and can be effectively managed with the right understanding and treatment.

Recognising Seasonal Affective Disorder Symptoms

Spotting the symptoms of Seasonal Affective Disorder can be the first step towards getting help. This form of depression is unique due to its seasonal nature and the cyclical pattern it follows. However, since it shares many symptoms with other forms of depression, it can sometimes be difficult to identify.

Symptoms of Seasonal Affective Disorder: These are psychological and physical indicators that occur seasonally, typically during the winter, including feeling low, fatigue, weight gain, and a desire to be alone.

Common Symptoms of Seasonal Affective Disorder

There are noticeable symptoms you might be experiencing if you're affected by Seasonal Affective Disorder. It's worth noting that the severity of these symptoms can differ greatly from person to person. They can range from mild to severe and often interfere with daily functioning.

Depressed Mood: This is characterised by feeling low or depressed most of the day, every day.
Loss of Interest: You might lose interest in activities you once enjoyed. This change often coincides with the change of seasons.
Changes in Sleep Patterns: Needing more sleep than normal or difficulty staying awake.
Changes in Appetite: You may see an increased craving for foods high in carbohydrates.
Difficulty Concentrating: Having trouble focusing on tasks, or making decisions can also be a symptom of SAD.

If you find yourself experiencing any of these symptoms with a distinct seasonal pattern, consulting with a healthcare professional could be a good course of action.

Seasonal Affective Disorder often goes undiagnosed as people dismiss it as 'winter blues'. However, the impact on a person's life and well-being can be substantial. Hence, awareness of this disorder and its symptoms is a crucial step towards seeking help and treatment.

Difference Between Seasonal Affective Disorder and Regular Depression Symptoms

While similar in many ways, there are key distinctions between the symptoms of Seasonal Affective Disorder and regular depression. These differences can help in accurately identifying and treating the condition.

An example of such a difference could be seen in Jane. In most months, Jane functions normally and doesn't exhibit signs of depression. However, during the winter months, Jane experiences a drop in her mood, has an increased appetite (specifically craving sweets and starchy foods), and sleeps more than usual. These cyclical changes that occur every winter are typical of Seasonal Affective Disorder, not regular depression that persists throughout the year.

	Regular Depression	Seasonal Affective Disorder
Symptoms Frequency	Persistent throughout the year	Occur during specific seasons every year
Changes in Appetite	Often decreased appetite	Increased craving for foods high in carbohydrates
Sleep patterns	Insomnia or hypersomnia	Hypersomnia is more common

In conclusion, understanding and recognising the difference between Seasonal Affective Disorder and regular depression is instrumental in receiving appropriate treatment and support.

Exploring the Causes of Seasonal Affective Disorder

Delving into the causes behind Seasonal Affective Disorder (SAD) will help you understand why certain individuals are more susceptible to this condition during specific seasons. Just like other forms of depression, SAD is a complex disorder with various factors contributing to its onset.

Major Seasonal Affective Disorder Causes

The intricate mix of genetic, biological and environmental elements can contribute to the onset of Seasonal Affective Disorder. Though it's often related to the reduced level of sunlight during the fall and winter months, the exact cause is not completely understood. These are the often-involved factors:

Biological Internal Clock (Circadian Rhythm): The decreased sunlight in fall and winter may disrupt your body's internal clock, which lets you know when you should sleep or be awake. This disruption in circadian rhythms could lead to feelings of depression.
Serotonin Levels: This a brain chemical (neurotransmitter) that impacts mood, and reduced sunlight can cause a drop in serotonin triggering depression.
Melatonin Levels: The change in seasons can disrupt the balance of the body's level of melatonin, which plays a role in sleep patterns and mood.

Melatonin: A hormone produced by the pineal gland in the brain that helps control sleep-wake cycles. Its production is affected by light and seasonal changes.

The association between light exposure and mood is rooted in the history of life on Earth. Organisms developed biological rhythms aligned with the Earth's rotation, influencing their sleep-wake cycles, hunting and feeding patterns, even reproduction. Therefore, it's not surprising that modern humans can be affected by changes in light exposure, like during the shorter daylight hours in the fall and winter.

Each of these elements alone, or in combination, can play a significant role in sparking off the conditions for Seasonal Affective Disorder to occur. Nonetheless, it's crucial to note that diagnosing SAD should be based on the recurrence of the typical winter depressive symptoms for at least two consecutive years.

Factors that Influence Seasonal Affective Disorder

While the causes we've examined indeed play a key role in triggering SAD, it's also necessary to know that certain factors can influence an individual’s susceptibility to Seasonal Affective Disorder.

Geographic Location	SAD is more common in people living far north or south of the equator due to decreased sunlight during the winter and longer days during the summer months.
Age	Young people have a higher risk of winter SAD, and winter SAD is less likely to occur in older adults.
Family History	Those with a family history of depression are more likely to develop SAD than those without such a history.

For instance, consider the case of Sam. He lives in the northernmost part of Scotland, where during winter months the daylight hours are significantly reduced. Sam has been noticing that he consistently feels down during these months, with increasing sleepiness and lethargy. His mother had suffered from depression, too. All these factors — geographic location, age, and family history — influence Sam's susceptibility to Seasonal Affective Disorder.

To sum up, understanding these causes and influencing factors is crucial in the journey of managing the effects of Seasonal Affective Disorder.

Learning About Seasonal Affective Disorder Treatment Options

Unravelling the complexity of Seasonal Affective Disorder (SAD) starts with understanding the breadth of treatments available for this condition. This array of treatments blends a range of approaches, all aimed at mitigating the symptoms of SAD. Awareness about these diverse treatment options can empower you in your journey of managing SAD effectively.

Effective Treatment Methods for Seasonal Affective Disorder

Seasonal Affective Disorder, despite its cyclical occurrence and severity, is a condition that can be controlled with appropriate treatment. Various methods available are tailored to the individual's symptoms and preferences, as well as the severity of the disorder. Let's delve into the most common ways to treat SAD.

Light Therapy (Phototherapy): This is one of the most common treatments where you sit a few feet from a special light box to expose you to bright light, simulating natural outdoor light. This exposure can alter your brain chemicals linked to mood, easing SAD symptoms.
Psychotherapy (Cognitive Behavioural Therapy): A type of psychotherapy known as cognitive behavioural therapy can help you learn healthy habits, manage stress and identify and change negative thoughts that may make you feel worse. CBT adapted for SAD may include light therapy.
Medications: Some people with SAD benefit from antidepressant treatment, especially if symptoms are severe. It's important to discuss the potential benefits and risks with a doctor.
Vitamin D: This is still being studied as a possible treatment for SAD. It's believed that the decrease in sunlight contributes to a Vitamin D deficiency that triggers symptoms of SAD, but the research is inconclusive. Some studies suggest taking Vitamin D supplements can help, but consult with a healthcare professional first.

Cognitive Behavioural Therapy (CBT): A type of talk therapy (psychotherapy) that helps individuals become aware of inaccurate or negative thinking, view challenging situations more clearly and respond more effectively.

Light therapy for treating SAD was first proposed in 1984, with numerous research studies since then proving its effectiveness. The therapeutic mechanism of action is thought to be linked to the principle that light exposure suppresses the secretion of melatonin in the brain, just as dawn does naturally, waking you up and enhancing mood and energy levels.

Each of these treatments has its own pros and cons but, ultimately, it will vary according to individual personal experience, symptom severity and healthcare feedback.

Usage of Seasonal Affective Disorder Medication and its Effectiveness

For some, medication could be a vital part of managing Seasonal Affective Disorder, particularly in severe cases or where symptoms persist despite light therapy or psychotherapy. Different classes of medications can alleviate the symptoms of SAD.

Selective Serotonin Reuptake Inhibitors (SSRIs): These are often the first choice of medication. They are designed to increase the levels of serotonin, a mood-regulating neurotransmitter in the brain, to help alleviate the symptoms of depression.
Bupropion: An extended-release version of this antidepressant is specifically approved by the Food and Drug Administration to treat SAD.

Serotonin: A neurotransmitter, a type of chemical that helps transmit signals in the brain. Although it is manufactured in the brain, where it performs its primary functions, some 90% of our serotonin supply is found in the digestive tract and in blood platelets.

Medications for SAD work by acting on neurotransmitters or hormones that regulate mood, sleep and appetite. Patients usually start treatment before symptoms would normally start in the fall or early winter, and then continue treatment through the following spring. Side effects can occur with the use of these medications, and they can interact with other drugs. Therefore, it's recommended to discuss all these aspects with a healthcare provider.

Medication	How it Works	Potential Side Effects
Selective Serotonin Reuptake Inhibitors (SSRIs)	Increases serotonin levels in the brain	Insomnia, rash, diarrhoea, upset stomach
Bupropion	Acts on norepinephrine and dopamine, other neurotransmitters in the brain	Dry mouth, nausea, insomnia, tremor

Let's take the example of Alice. Alice has been diagnosed with SAD for several years. She has tried light therapy and CBT, but her symptoms continue. Therefore, her healthcare provider suggests adding an SSRI to her treatment plan. Alice begins taking the medication in early autumn before her symptoms usually appear. By proactively managing her disorder in this manner, Alice finds that her symptoms during the winter months are now more manageable. This showcases how medication, used correctly and under the supervision of a healthcare professional, can be beneficial in treating Seasonal Affective Disorder.

The effectiveness of medication for SAD can depend on several factors including the individual's body chemistry, the severity of the condition, adherence to treatment, and other co-existing psychological conditions. Always consider these factors and consult with a healthcare provider when weighing the advantages of this treatment method for SAD.

Implementing Seasonal Affective Disorder Self-Care Techniques

Self-care forms a critical part of managing any psychological condition, and Seasonal Affective Disorder (SAD) is no exception. Simple lifestyle changes can greatly empower you in mitigating the impact and severity of SAD symptoms.

Essential Self-Care Strategies for Managing Seasonal Affective Disorder

Implementing a routine that encourages self-care is invaluable when trying to edge out the symptoms of Seasonal Affective Disorder. These techniques aim at improving your overall wellbeing by making you the focus. These actions, although seemingly ordinary, can have a positive influence on your mood and energy levels:

Maintain Regular Sleep Pattern: Aim to awaken and retire at the same times each day, even on your days off. This consistency reinforces your body's sleep-wake cycle and aids restful sleep, which is crucial in managing depression.
Healthy Eating: SAD can make you crave foods high in carbohydrates, such as pasta and bread. Instead, focus on a balanced diet full of a variety of fruits, vegetables, lean meats, and low-fat dairy products.
Engage in Regular Exercise or Sports: The feel-good endorphins produced during physical activity, and the distraction it provides from tiring thoughts, can be an effective mood lifeboat.
Seek the Sun: Get outside for a walk, take breaks outside if you can, and make sure your environment is sunny and bright.
Stay Connected: Engage in social activities, even if you don't feel like it. Being around other people in a fun and relaxed environment can be therapeutic and enjoyable.

Endorphins: Biochemical substances produced by the body that function as natural painkillers. They are also linked to pleasure feelings, promoting a sense of well-being and happiness.

It's worth noting that adhering to these self-care strategies can boost your overall mental health and not just alleviate your SAD symptoms. These techniques are designed to cultivate a healthier lifestyle that is less likely to foster any form of depression. You should experience a greater sense of general wellbeing and decreased susceptibility to SAD when the winter months roll around if you stick to these behavioural changes religiously.

Indeed, self-care pertains to the actions administered by the individual, dependent on self-discipline and commitment. These methods may be particularly beneficial during a global health crisis such as the COVID-19 pandemic, when mental health concerns are increasing and access to in-person therapy might be limited.

Incorporating Self-Care into your Daily Routine to Mitigate Seasonal Affective Disorder Symptoms

Incorporating these self-care principles within your daily routine is an effective way to ensure that they become habitual actions. This will not only aid in their effectiveness but help you in making vital lifestyle changes. Here is a guideline to help you integrate these self-care recommendations into your daily life:

Morning Sunlight Exposure: Begin your day by opening curtains and windows to let as much natural light in as possible. If possible, spend the first few minutes of your day in natural sunlight. This can help reset your biological clock and stimulate serotonin production.
Daily Exercise: Schedule your workouts in the morning if possible. Not only will they help to wake up your mind and body, but you'll also benefit from natural light if you're able to get outside. Exercise can range from a brisk walk to a home fitness video.
Balanced Eating: Prepare your meals ahead of time to ensure that you have quick, easy access to balanced and nutritious meals. Make sure to include enough fruits and vegetables and avoid overeating, especially carbohydrates. Drink lots of water and minimise the intake of caffeine and alcohol, both of which can negatively affect your sleep.
Staying Social: Try to plan regular catch-ups with friends or family, preferably in a well-lit environment. Even over a video call can help lift your mood and maintain essential social interactions. If you're comfortable in group settings, consider joining clubs or groups that interest you.
Consistent Sleep Schedule: As the day winds down, avoid screens for at least an hour before bedtime to promote a better night's sleep. Aim to stick to consistent times for going to bed and waking up, including on weekends to maintain a regular sleep pattern.

Serotonin: This is a key hormone and neurotransmitter that stabilises our mood, feelings of well-being, and contributes to happiness and overall well-being.

Imagine George, a software engineer, who has noticed a recurring pattern of mood changes during the winter months. He identifies his struggle with Seasonal Affective Disorder and decides to incorporate self-care strategies into his daily routine. George begins his day with a morning walk, exposing himself to as much natural sunlight as possible. He sets a goal to exercise daily, even if it's just for 15 minutes during his lunch break. He starts meal-prepping over the weekend, ensuring he has balanced meals during the workweek. George also invests in a light box to use on the shorter winter days, enhancing his exposure to light. During the evenings, George makes sure to turn off his work laptop and stops checking emails from his phone. By establishing this routine, George is incorporating effective self-care techniques to manage his Seasonal Affective Disorder symptoms better.

While it might seem challenging to sustain these habits initially, with time and consistency, you'll notice that they seamlessly fit into your daily life. Employing these strategies will leave you better equipped to handle the symptoms of Seasonal Affective Disorder even before they set in.
