You’re not alone. As daylight hours shorten and temperatures drop, many people experience a dip in mood, energy and motivation that can affect daily life. The good news is that there are proven strategies and practical tools that can help lift your mood, restore balance and make the winter months feel brighter and more manageable.
What is Seasonal Affective Disorder?
The acronym SAD sums up how one feels, especially during the cold winter season. Perhaps a little more serious than just the “winter blues”, SAD is a form of depression, a clinically recognised mood disorder that many people experience during the winter season each year, usually when days get darker earlier and the sunlight hours are limited. As a result, many people feel a “bit down” during the cold winter months.
We think this is one of many accurate descriptions of Seasonal Affective Disorder on the World Wide Web.
What may cause SAD?
The exact cause isn’t fully understood, but the likely combination of reduced sunlight disrupting the body’s internal clock (circadian rhythm), potentially reducing Vitamin D and changes in the levels of mood-related brain chemicals like Serotonin (a feel-good hormone) and Melatonin, a hormone important for maintaining the normal sleep−wake cycle.
People who experience SAD during the winter produce too much melatonin, increasing tiredness and sleepiness.
The negative impacts of SAD on mental health and well-being
SAD affects each individual differently, ranging from mildly disruptive to severely impairing symptoms experienced during winter. Some of the symptoms, such as persistent low mood, sadness, hopelessness, tearfulness, or emotional numbness, can reduce their enjoyment of daily life.
Other negative impacts include difficulty concentrating or making decisions, low motivation, oversleeping or insomnia, neglect of hobbies or self-care, and in severe cases, an increased risk of serious mental health issues such as anxiety, eating disorders, substance misuse or suicidal thoughts.
Another major impact is impaired concentration and cognitive function. People with SAD often describe “brain fog,” memory difficulties and reduced productivity affecting work, leading to frustration or self-confidence.
The symptoms are real, affecting a person's mood and physical behaviour, and one should seriously consider developing some effective habits to manage SAD.
So, where does one start?
First, let’s develop some effective habits
We know developing a good habit takes time. The process of forming a habit in the early stages combines willpower (especially doing something you don’t like or aren’t used to) and consistent repetition, one that eventually develops into a beneficial habit that becomes second nature, like driving a car.
When any particular habit is formed is when you know it’s become a habit, one that no longer needs a strong will (or at all) to sustain over an extended period. The natural byproduct of it comes consistency, where one reaps the benefits of the habit. Take note, we’re referring to the good, effective habits here.
So, that ends a short intro to developing a habit. Granted, not first aid, but definitely a mental health-related subject. What next?
What effective habits are we referring to?
There is no “one-size-fits-all solution” or “cure”. A combination of lifestyle habits, environmental adjustments, and, if absolutely necessary, seeking medical help can significantly reduce SAD’s impact.
Below are common strategies recommended:
Maximise light exposure
Try to spend more time outdoors during daylight by taking a walk, even on cloudy days helps. Morning daylight exposure helps reset the circadian rhythm.
Adjust your home and work environments, such as opening curtains or blinds, keeping windows unobstructed and rooms well ventilated and consider skylights or brighter lamps.
Another effective option is using a “light box”, which is a bright light therapy, typically 10,000 lux, for 10–15 minutes each morning through winter. Many people find this helpful for missing sunlight.
Consistent Sleep & Daily Routine
It’s important to maintain a regular sleep-wake pattern, even on weekends. Try not to oversleep or take frequent daytime naps, especially in winter-onset SAD.
Avoid the use of a mobile phone or exposure to screens and bright lights emitting blue light at least two hours before bed, allowing melatonin (sleep hormone) to rise, preventing mental stimulation and aiding good sleep.
Keep moving, active and exercise regularly
Physical activity helps release mood-enhancing chemicals like endorphins, may reduce stress and anxiety, and boosts energy levels and overall well-being. Exercises such as weight training, light activities like walking or a leisurely park run or indoor exercise such as yoga, dance, or home workouts can still be equally as beneficial.
Eating a well-balanced diet
Enjoying a nutritious well well-balanced diet with plenty of protein, healthy fats with fresh fruit and vegetables, including foods rich in omega-3 fatty acids (e.g. salmon or sardines), and possibly supplementing with vitamin D (or vitamin-D-rich foods) will support mood regulation.
Stay hydrated. Dehydration can worsen fatigue and mood.
Avoid or limit stimulants like excessive caffeine and alcohol that interfere with mood or sleep and cause dehydration.
Psychological strategies and social support
Talking therapies, especially Cognitive Behavioural Therapy (CBT), can help by re-framing negative thoughts and managing avoidance behaviours or stress. Keep active socially, maintaining contact with friends, family, or social groups helps counteract isolation, which often worsens SAD. Engage in hobbies or meaningful activities even when motivation is low. This is where routine and structure can help.
Seek professional help
When the above lifestyle adjustments do not help with SAD, another recommended option is to seek medical help. Your physician, as a first resort, may ask you to supplement with Vitamin D, especially when a deficiency is suspected. This may help when combined with lifestyle changes. In severe cases antidepressant may be prescribed that can be effective for SAD, again combined with lifestyle changes. Antidepressants work by suppressing certain chemicals involved in mood or stress that cause SAD.
Bringing light back into the season
Winter may bring shorter days, but with awareness and early action with supportive habits, we can lighten the emotional load. By understanding SAD and taking proactive steps, one can move through the season feeling more upbeat, proving that even in the darkest months, there are plenty of ways to bring more light into life.
For many of us, the Christmas festive season brings us together with friends and family works wonders in lifting the seasonal low mood. A time with plenty of joy, fun and laughter, no doubt helps.
One thing we do know is that using an effective strategy to combat Seasonal Affective Disorder can be an effective solution.
