As a mental health therapist, and someone who used to struggle with seasonal depression, I have done research to better understand this disorder that so many people struggle with. This post is all about understanding and managing seasonal depression.
What is Seasonal Depression?
Seasonal depression, clinically known as Seasonal Affective Disorder, is a mood disorder that impacts at least 5% of Americans every year. People with seasonal depression tend to begin feeling low mood, poor energy, anxiety, and irritability in the beginning of Fall, and by the time the holidays arrive, these symptoms can develop even further into hopelessness, changes in eating and sleeping patterns, feelings of exhaustion, and no longer enjoying things that normally bring them joy.
If this sounds like a familiar feeling, you may be struggling with seasonal depression. If it doesn’t quite fit your experience, it may be helpful to know that many people experience a milder form of winter blues, which can be just as debilitating, while others encounter grief due to holiday memories or expectations, loss of daylight activities, or feeling like their year is coming to an end.
What Causes Seasonal Depression?
Lack of sunlight is a big culprit of seasonal depression. You may have grown up hearing things like, “People in Seattle have higher levels of depression and suicide because they have less sunlight.” This is not entirely inaccurate. Sunlight helps to regulate our serotonin (one of our happy chemicals), helps to provide Vitamin D, which also affects our serotonin and energy levels, and increases our melatonin levels, which helps us get proper sleep at night.
The lack of sunlight could be impacting you at a biological level, especially considering that many people, specifically women, already struggle with low vitamin D.
Our circadian rhythm also has a big impact on our daily living and mood. Our bodies work on a 24-hour cycle, naturally shifting hormones, regulating energy levels, and changing heartrate to match the time of day. Light and dark affect how our internal clock adjusts, and if you struggle with seasonal depression, your body might be struggling to adapt to the changes in season.
One way to know if your circadian rhythm is off is to notice how your energy levels are throughout the day, and how restfully you are sleeping at night. Ideally, our bodies will have energy in the morning, peak at some point during the day, and slowly decrease in energy as our bodies move toward bedtime.
It’s important to note that other things could impact energy levels during the day, such as stress, trauma, nutrition, and exercise. It may be hard to discover the exact cause, but ultimately, they are all connected to one another.
Lastly, our thinking patterns might have a big impact on how our bodies respond to the change in season. Thinking patterns can affect the chemicals in our brains and the chemicals in our brains can affect our thinking patterns. Even with this “chicken or the egg” debate, we know that there is a correlation between thoughts and mood. Many people with seasonal depression express experiencing negative thinking patterns about their own bodies (I hate that I’m so tired!), the holidays (ugh, the holidays are here again), the lack of daytime (it’s so darrrrrk), or many other things, that can bring their mood down.
What can I do to help seasonal depression?
Luckily there are many tools that can help make seasonal depression feel less depressing. Let’s address these symptoms at the root causes.
Get more sun!
No, we can’t make the sun be out longer than it is, but we can do our best to get as much sunlight as possible. Wherever possible, whether it’s sitting outside in the morning sun (bundle up if you’re in a colder state!), sitting by a window at work or home, or going for an outside walk at lunchtime, take advantage of whatever sunlight is available to you.
If you work somewhere that hogs all your daylight hours and doesn’t provide much flexibility to get outside, there is the option of purchasing a light therapy lamp. These come in all shapes and sizes, perfect for sitting on the desk in an office or at the dinner table, and can help simulate sunlight, increasing serotonin and melatonin levels. Additionally, if you have lightbulbs in your home, consider changing them out for a white natural light, instead of a yellow tone. This can trick the brain into thinking it’s still daylight outside.
Boost Vitamin D.
Vitamin D is readily available in the form of vitamins or supplements and can also be increased by the food we eat. Foods that are high in vitamin D include fish, like salmon, tuna, and sardines, egg yolk, mushrooms, milk (cow or soy), and orange juice.
Improve circadian rhythm.
Other than sunlight, there are many things that can affect circadian rhythm.
- Try and keep a consistent sleep routine, winding down at night and getting in bed around the same time, even if you aren’t sleepy.
- Get a dawn simulator if you wake up to a dark morning. Dawn simulators can simulate the rising sun, slowly increasing light as it’s time for you to wake up.
- Reduce light before bedtime. This includes phone and TV! When you begin winding down, start to adjust the lights in your home so your brain knows that it’s time to start calming down. Try doing things that don’t require as much light stimulation, like meditating, reading a book with a small nightlight, or stretching. (Lifehack: most phones have a bluelight filter, which is thought to help reduce the negative effects of the light when using your phone at night).
- Avoid caffeine and sugar later in the day. While most won’t be willing to give up sugar or caffeine completely, myself included, these can significantly impact your energy levels. Try limiting caffeine to the morning time and reducing sugar intake closer to bedtime to avoid a boost of energy when you’re trying to sleep.
- Exercise during the day. Exercise also has a direct impact on Serotonin and other brain chemicals that regulate our mood and circadian rhythm. Exercising during the “peak awake hours” can help our body to know what times of day it needs to adjust the energy levels around.
- Short naps only. Naps can definitely confuse the body into not knowing when to sleep. Naps can be a great way to rest and recharge but try and keep them short (around half an hour) and in the afternoon, so that your body doesn’t confuse it with actual sleep time.
Do activities in the dark
You get out of work and…it’s dark already. You can’t go bike riding, unless you get a helmet light, it’s too cold for watersports, and you already feel like it’s too late to make plans. Try to remember that at this same time during the Summer, you likely still had energy to make plans or go out. Your brain, thinking that it’s night, may start to make you feel tired and ready to wind down. Try to explore what is available in your area. Find a safe place to go for walks or jog at night, find indoor activities such as pool or bowling, meet your friends for dinner or the movies. Let your brain know that just because it is dark outside, does not mean it is time to shut down.
Boost Mental Health Overall
Seasonal depression is not an isolated experience, meaning that all the other things you normally struggle with are still there. There are a quite a bit of things that can improve mental health, like journaling, socializing, daily gratitude expressions, yoga, and breathing techniques. As cliché as these things seems, they do give your mental health a boost!
If your low mood and negative thoughts around the winter or fall are caused by more than the things mentioned above, it may be good to explore talk therapy. The holidays and winter can be filled with grief, expectations, stress around family, trauma triggers and more. These things may be exacerbated by seasonal depression, and it could be helpful to get a helping hand.
Remember, it is difficult to challenge thinking patterns, adjust circadian rhythm, and to do things when your energy levels are already low. Give yourself grace and know that some days will be harder than others, and you are doing the best that you can!
