SEASONAL AFFECTIVE DISORDER OR THE WINTER BLUES?
As the days grow shorter and darker, many of us notice a change in our mood, energy and motivation. But when is it more than the winter blues?
Thank you to Helen O' Callaghan of Irish Examiner newspaper for interviewing me for her article on Seasonal Affective Disorder (SAD), published last Friday. I was delighted to have the opportunity to raise awareness of this important mental health issue.
WHAT IS SEASONAL AFFECTIVE DISORDER?
SAD is a form of depression that follows a seasonal pattern. It most commonly begins in autumn or winter and improves as spring arrives. Symptoms can include persistent low mood, loss of interest in activities you would normally enjoy, fatigue, difficulty concentrating, increased sleep, changes in appetite and a tendency to withdraw from others. For some people, these symptoms can significantly affect their work, relationships and everyday life.
So, how is it different from the winter blues?
The winter blues are generally milder. You might feel less energetic, miss the brighter days or find it harder to motivate yourself, but you can usually continue with your daily activities.
SAD is more debilitating. It can affect your ability to function and your enjoyment of life. It is not simply a case of disliking the weather or wanting to feel more positive.
WHAT HAPPENS IN THE BRAIN?
The science behind our response to seasonal changes:-
Our circadian rhythm is our internal 24-hour body clock. It helps regulate when we feel awake and alert and when we become sleepy. Light entering our eyes sends signals to the brain's internal clock, located in the hypothalamus.
When daylight hours decrease, this system may become disrupted in people who are vulnerable to SAD. Changes in melatonin, the hormone involved in sleep regulation, and serotonin, a brain chemical involved in mood, may contribute to symptoms. The exact causes of SAD are not fully understood, and several factors are likely to be involved.
WHAT CAN WE DO TO SUPPORT OURSELVES?
🌿 MAKE THE MOST OF DAYLIGHT. Get outdoors during the day, ideally in the morning. Even a short walk on a cloudy day can be beneficial.
🌿 KEEP MOVING. Regular physical activity can support mood, energy and general wellbeing. Start small and choose something you enjoy.
🌿 PROTECT YOUR SLEEP ROUTINE. Try to go to bed and get up at consistent times. Regularity helps support your body clock.
🌿 STAY CONNECTED. Make time for friends, family and activities that give you a sense of enjoyment or meaning. When our mood is low, withdrawing can feel easier, but connection matters.
🌿 BE KIND TO YOURSELF. If your energy is lower, break tasks into manageable steps rather than expecting yourself to operate at your usual pace.
A TIP FROM NEUROSCIENCE
Think of morning daylight as a signal to your brain that the day has begun. Getting outside early in the day can help synchronise your body clock, supporting your natural sleep-wake rhythm. A short morning walk can be a simple way to build this into your routine.
WHEN SHOULD YOU SEEK HELP?
If low mood persists, affects your daily life or returns in a similar pattern each winter, speak with your GP. SAD is treatable. Depending on your circumstances, treatment may include counselling or other talk therapies, medication or light therapy.
If you are considering a light box, seek medical advice about its suitability, particularly if you have an eye condition or take medication that increases light sensitivity.
We cannot control how much daylight the winter brings, but we can take steps to support our mental health through the darker months. Understanding what is happening is an important first step. And remember, you do not have to wait until things feel unbearable before reaching out for support.
