Ayurvedic Wisdom
ऋतुपरिवर्तने मनो विषीदति, तमसा आवृतं चित्तं प्रकाशं वाञ्छति। कालस्य प्रभावेण जीवः क्लिश्यते, स्वस्थता च ऋतुसाम्ये विराजते॥
Ṛtu-parivartane mano viṣīdati, tamasā āvṛtaṃ cittaṃ prakāśaṃ vāñchati. Kālasya prabhāveṇa jīvaḥ kliśyate, svasthatā ca ṛtu-sāmye virājate.
As seasons shift, the mind may grow heavy with sorrow, and a spirit shrouded in darkness longs for light. The passage of time brings its own burdens to living beings, yet true wellbeing shines forth again when balance with the seasons is restored.
Symptoms of Seasonal affective disorder
- Persistent low mood or sadness that appears during a particular season, most often autumn or winter
- Loss of interest in activities that are normally enjoyable
- Feeling sluggish, lethargic, or having very low energy throughout the day
- Oversleeping or difficulty waking in the morning
- Increased appetite, particularly cravings for starchy or sugary foods
- Difficulty concentrating, thinking clearly, or making decisions
- Feeling withdrawn, irritable, or anxious, particularly in social situations
- A sense of hopelessness or worthlessness that lifts as the season changes
Causes of Seasonal affective disorder
- Reduced exposure to natural sunlight during shorter autumn and winter days, which may disrupt the body's internal clock
- Changes in serotonin levels — a brain chemical linked to mood — which may be influenced by diminished sunlight
- Disruption to melatonin production, a hormone that regulates sleep and wakefulness, causing imbalances in mood and energy
- Disruption to the body's circadian rhythm (internal 24-hour cycle) due to seasonal changes in light and darkness
- A family history or personal history of depression or other mood-related conditions, which may increase susceptibility
- Living at higher latitudes where winter days are significantly shorter and sunlight is scarce for extended periods
- Spending most of the day indoors with minimal access to natural light, whether due to work patterns or lifestyle
- Psychological and social factors such as increased isolation during colder months, reduced outdoor activity, and disrupted routines
Diet for Seasonal affective disorder
- Include foods rich in complex carbohydrates such as oats, whole grains, and legumes, which may support steady energy levels and mood throughout the day
- Eat oily fish such as salmon, mackerel, or sardines regularly, as they are good sources of omega-3 fatty acids traditionally linked to brain and mood health
- Choose foods that provide vitamin D naturally, such as eggs, fortified dairy or plant milks, and mushrooms exposed to sunlight, especially during darker months
- Keep blood sugar stable by eating regular, balanced meals rather than skipping meals, which can contribute to energy crashes and low mood
- Include a variety of colourful fruits and vegetables, particularly those rich in folate such as spinach, broccoli, and citrus fruits, which support overall nervous system wellbeing
- Stay well hydrated throughout the day, as even mild dehydration can affect concentration, mood, and energy levels
- Tryptophan-rich foods such as turkey, bananas, nuts, and seeds may support the body's natural serotonin production
- Warming, nourishing meals such as soups, stews, and porridge can be both comforting and supportive of digestive health during cold seasons
Foods to Avoid in Seasonal affective disorder
- Limit refined sugars and heavily sweetened foods such as sweets, biscuits, and sugary drinks, which may cause rapid blood sugar spikes followed by energy and mood crashes
- Reduce consumption of ultra-processed convenience foods, which tend to be low in nutrients important for mood and brain health
- Limit alcohol, as it acts as a depressant on the nervous system and can worsen low mood, disrupt sleep, and intensify feelings of sadness
- Avoid relying heavily on caffeine to manage fatigue, as excessive intake can disrupt sleep patterns and increase feelings of anxiety
- Cut back on heavily refined white bread, white pasta, and similar low-fibre carbohydrates that offer little nutritional support for mood and energy
- Be mindful of emotional or comfort eating during low-mood periods, particularly late-night snacking on energy-dense, nutrient-poor foods
- Reduce intake of high-fat, high-sugar processed snacks that may contribute to inflammation and poor energy regulation over time
Prevention of Seasonal affective disorder
- Make a daily habit of spending time outdoors during daylight hours, even on overcast days, to maximise natural light exposure
- Maintain a consistent daily routine for sleeping and waking, as a stable circadian rhythm supports mood regulation throughout seasonal changes
- Stay socially connected during darker months by scheduling regular time with friends, family, or community groups to reduce feelings of isolation
- Engage in regular physical activity such as walking, yoga, or cycling, which supports mood, energy, and sleep quality
- Create a light-filled living and working environment by keeping curtains open, sitting near windows, and keeping indoor spaces bright and welcoming
- Prepare mentally and practically for the seasonal transition in advance — plan enjoyable activities and social commitments for the darker months
- Practise stress-management techniques such as mindful breathing, journalling, or gentle movement to help maintain emotional resilience
- Monitor your mood across seasons and seek support early if you notice recurring patterns of low mood each year
When to See a Doctor for Seasonal affective disorder
- Consult a qualified healthcare professional if feelings of low mood, sadness, or hopelessness persist for two weeks or more, particularly if they appear at the same time each year
- Seek professional support if symptoms are significantly affecting your ability to work, maintain relationships, or carry out everyday responsibilities
- Do not delay seeking help if you experience feelings of worthlessness, persistent guilt, or a sense that life is not worth living
- Seek immediate medical attention or contact your local emergency medical services if you have thoughts of self-harm or suicide — this is a medical emergency requiring urgent care
- Consult a professional if your sleep disturbances, appetite changes, or fatigue become severe and are not responding to basic self-care
- If you are unsure whether your seasonal mood changes qualify as a disorder or a passing low mood, a qualified healthcare professional can help clarify and guide next steps
- Consider consulting a qualified Ayurvedic practitioner if you are interested in integrating traditional wellness approaches alongside conventional support, particularly for managing recurring seasonal patterns
- Seek review if you have a previous diagnosis of depression, bipolar disorder, or another mood condition that appears to worsen with seasonal changes
Herbal & Home Remedies for Seasonal affective disorder
- Spend at least 20–30 minutes outdoors each day during daylight hours, even on cloudy days, to maximise exposure to natural light
- Keep living and working spaces as bright as possible by opening curtains fully, positioning seating near windows, and using warm-toned lighting in the evenings
- Establish a consistent sleep schedule by going to bed and waking at the same time each day to help regulate the body's internal rhythm
- Practise slow, mindful breathing or simple relaxation exercises in the morning to help set a calm and positive tone for the day
- Gentle indoor movement such as stretching, yoga, or a short walk — even around the home — can help lift energy and ease a heavy mood on low-motivation days
- Keeping a simple mood or gratitude journal each evening may help identify seasonal patterns and provide a gentle sense of daily structure and reflection
Home Remedies for Seasonal affective disorder
- Maintain a warm, comfortable home environment during cold months, as physical warmth and cosiness can have a gentle positive effect on overall mood
- Create a morning light ritual — open blinds immediately upon waking and sit near a window while having breakfast to signal wakefulness to the body
- Stay socially connected by scheduling regular calls, visits, or shared activities with trusted friends or family, even when motivation is low
- Limit screen time and bright blue-light exposure in the hour before bed to support better quality sleep during long dark nights
- Prepare nourishing, warming home-cooked meals as a daily act of self-care, which can also provide structure and a sense of purpose during difficult months
- Engage in enjoyable indoor hobbies or creative activities — crafts, reading, music, or cooking — to maintain a sense of pleasure and engagement throughout the season

Frequently Asked Questions About Seasonal affective disorder
What exactly is seasonal affective disorder?
Seasonal affective disorder, often called SAD or the 'winter blues', is a type of depression that follows a seasonal pattern. Most people experience it during the autumn and winter months when daylight hours are shorter, though a less common form occurs in spring and summer. Symptoms typically include persistent low mood, fatigue, oversleeping, and changes in appetite. Importantly, symptoms generally lift as the seasons change, distinguishing SAD from other forms of depression.
Is seasonal affective disorder a serious condition?
Yes, SAD is a recognised mood disorder that can significantly affect a person's quality of life, relationships, and ability to function day to day. It is not simply 'feeling a bit down in winter' — for those with moderate to severe SAD, symptoms can be debilitating. Seeking professional support is important if symptoms persist or worsen, particularly if thoughts of self-harm or hopelessness arise. With the right support, most people find effective ways to manage the condition.
What causes seasonal affective disorder?
The exact cause is not fully understood, but reduced exposure to natural sunlight during shorter winter days is considered a key factor. This may disrupt the body's internal clock, lower serotonin levels (a mood-regulating brain chemical), and alter melatonin production, which affects sleep and wakefulness. Genetic predisposition, living at higher latitudes, and spending most of the day indoors are also thought to increase susceptibility.
Can seasonal affective disorder come back every year?
Yes, SAD is characterised by its recurring seasonal pattern. Many people experience symptoms at the same time each year, typically as autumn transitions into winter. Recognising this pattern early is actually helpful, as it allows individuals to put supportive habits and professional care in place before symptoms become severe. Consistent lifestyle routines, light exposure habits, and professional monitoring can help reduce the impact year on year.
Can children and older adults develop seasonal affective disorder?
Yes, SAD can affect people across all age groups, including children, teenagers, and older adults, though it is most commonly diagnosed in adults between their twenties and forties. In children and adolescents, symptoms may appear as irritability, difficulty at school, withdrawal from friends, or changes in sleep and appetite. Older adults may be more vulnerable due to reduced outdoor activity and social isolation during colder months. A qualified professional can help assess symptoms in any age group.
What foods might support mood during winter months?
A balanced diet rich in complex carbohydrates, omega-3 fatty acids, and vitamin D-containing foods may support general mood and energy during darker months. Oily fish, whole grains, leafy vegetables, eggs, nuts, seeds, and bananas are often highlighted for their nutritional profile. Eating regular, balanced meals to keep blood sugar stable and staying well hydrated are also helpful habits. No single food treats or cures SAD, but thoughtful nutrition is a useful part of overall wellbeing.
Does light therapy help with seasonal affective disorder?
Light therapy — using a specially designed bright light box — is one of the most widely explored conventional approaches for SAD. The aim is to compensate for reduced natural sunlight during winter months. It is typically used in the morning under professional guidance. Light therapy is not a guaranteed solution and is not suitable for everyone. Anyone considering it should discuss it with a qualified healthcare professional first, particularly if they have eye conditions or are taking certain medications.
Can Ayurveda support wellbeing in seasonal affective disorder?
Ayurveda views seasonal mood changes through the lens of Kapha and Vata imbalances, which are thought to increase during colder, darker months. Traditional Ayurvedic approaches may include warming herbal support, nourishing daily routines (dinacharya), and practices designed to balance the mind and senses. Herbs such as Ashwagandha and Brahmi have traditional associations with supporting mental clarity and emotional balance. Consulting a qualified Ayurvedic practitioner is advisable for personalised guidance, and Ayurvedic support should complement, not replace, professional care.
