Why You Feel Different As The Seasons Change: Mood, Sleep, Energy And Your Body Clock
Summary
As daylight changes, your body responds. You may notice lower mood, reduced motivation, disrupted sleep, food cravings, anxiety, poor concentration, gut changes, hormonal shifts or a heavier stress load.
At Counselling Experts, I work with adults, teenagers, and children online across Ireland and internationally, and in person in Adare, Newcastle West, Limerick, Abbeyfeale, Charleville, Kanturk, Midleton, Youghal, Lismore Cork, Dungarvan and Dublin. With over 20 years’ clinical experience across Counselling, Psychotherapy, Couples Counselling, Marriage Counselling, Clinical Medical Hypnotherapy, Clinical Hypnotherapy, RTT, and Registered Nutritionist services, I help clients understand what their mind and body may be responding to, rather than blaming themselves for feeling different.
Seasonal change is not “all in your head”. It is biology, psychology, sleep, stress, hormones, nutrition, relationships and nervous system regulation working together.
Why Seasonal Change Can Affect How You Feel
When the mornings become darker and the evenings arrive earlier, something subtle but powerful begins to shift.
You may find it harder to get out of bed. You may crave more sugar, carbohydrates or comfort foods. Your mood may feel flatter. Your patience may feel thinner. Sleep can become lighter, heavier, broken or harder to regulate.
For some people, this is mild and manageable. For others, it can affect work, parenting, school, relationships, motivation, eating patterns, alcohol use, vaping, gambling urges, emotional eating, anxiety, ADHD symptoms, OCD patterns, low mood, fatigue, gut symptoms and hormonal balance.
This does not mean you are weak or undisciplined. Your body may be responding to one of the strongest environmental signals it receives every day, light.
Light Is More Than Brightness. It Is Information
Light helps tell your brain what time it is.
Each morning, light enters your eyes and sends signals to a small part of the brain called the hypothalamus. Within the hypothalamus sits the suprachiasmatic nucleus, often called the master body clock.
Your circadian rhythm is your internal 24 hour body clock. It helps regulate:
- When you feel awake or sleepy
- When certain hormones rise and fall
- Body temperature
- Hunger and fullness cues
- Metabolism and energy use
- Focus and mental clarity
- Stress tolerance
- Sleep timing and sleep quality
When daylight reduces, your internal timing can shift. This is why you may feel “off” before you can explain exactly why.
Serotonin: Why Mood, Motivation And Cravings May Shift
Serotonin is a brain chemical involved in mood, appetite, motivation, sleep, impulse control and cognitive function. It is often described as a feel-good chemical, but its role is broader than that.
Research suggests that serotonin activity can be influenced by light exposure. In brighter months, some people may feel more energised, motivated and emotionally steady. As daylight decreases, serotonin-related activity may change.
This can show up as:
- Reduced motivation
- Lower mood
- Feeling emotionally flat
- Irritability
- Stronger cravings for sugar or refined carbohydrates
- Less interest in activities you usually enjoy
- Poorer concentration
- Increased emotional eating
If you already experience anxiety, depression, ADHD, OCD, autism-related sensory sensitivity, trauma-related stress, addictive patterns, eating difficulties or burnout, seasonal changes may feel more intense.
This is where Counselling, Psychotherapy, Clinical Hypnotherapy, Clinical Medical Hypnotherapy, RTT and Registered Nutritionist services can work together carefully. The aim is not to force you through the season. The aim is to understand the pattern and build practical, realistic ways to steady your system.
Melatonin: Why Sleep Can Feel Different
Melatonin is a hormone that helps regulate your sleep and wake cycle. It rises in response to darkness, signalling to your body that it is time to wind down.
As nights become longer, melatonin may rise earlier or stay elevated for longer. In theory, this should help sleep. In real life, modern routines can make things more complicated.
You may notice:
- Sleepiness earlier in the evening
- Difficulty waking in the morning
- Grogginess or a heavy feeling on waking
- More time in bed but less refreshing sleep
- Broken sleep
- Increased night-time scrolling
- More caffeine needed to get through the day
- A later second wind at night
Artificial light in the evening, screen use, stress, alcohol, irregular meals, pain, perimenopause, menopause, thyroid issues, blood sugar changes and gut symptoms can all affect sleep timing.
If sleep is becoming difficult, it may help to look beyond sleep hygiene alone. For many clients, sleep is connected to stress load, nervous system arousal, unresolved trauma, digestion, blood sugar, hormones, relationship strain, workload, grief or addiction patterns.
Why Your Nervous System May Feel More Reactive
Your nervous system is constantly scanning for safety, stress and change.
When daylight shifts, routines often shift too. Children return to school. Workloads increase. Social expectations change. People spend less time outdoors. Movement may reduce. Food choices can change. Evenings can feel longer, darker and lonelier.
Your nervous system may respond with:
- Anxiety
- Low mood
- Tension
- Restlessness
- Emotional overwhelm
- Reduced patience
- Shutdown or avoidance
- Stronger urges to self-soothe with food, alcohol, smoking, vaping, gambling, scrolling or other compulsive behaviours
This matters because many people interpret these changes as a personal failure.
They tell themselves, “I should be able to cope.”
But the more useful question may be, “What is my body responding to?”
Seasonal Change, The Gut-Brain Axis And Inflammation
The gut-brain axis is the two-way communication system between your digestive system and your brain. This connection involves nerves, immune signals, hormones, gut bacteria and chemical messengers.
When your sleep, stress and food patterns change, your gut may respond too.
Some people notice:
- Bloating
- Reflux
- IBS symptoms
- Constipation or loose stools
- Stronger cravings
- Blood sugar dips
- Fatigue after eating
- More sensitivity to certain foods
Inflammation can also influence mood, energy and pain. This may be relevant if you live with autoimmune symptoms or conditions such as coeliac disease, Hashimoto’s thyroiditis, rheumatoid arthritis, psoriasis, inflammatory bowel issues or chronic fatigue patterns.
As a Registered Nutritionist, I consider how food, blood sugar balance, caffeine, alcohol, sleep, gut health, inflammation and hormone patterns may be influencing your mental and physical wellbeing. This can sit alongside Counselling, Psychotherapy, RTT and Clinical Medical Hypnotherapy where appropriate.
Seasonal Affective Disorder And The Winter Dip
Seasonal affective disorder, often shortened to SAD, is a recognised pattern where mood and energy significantly worsen at a similar time each year, most commonly in autumn and winter.
Symptoms can include persistent low mood, loss of interest, irritability, anxiety, fatigue, sleep changes, appetite changes, low self-esteem, difficulty concentrating and reduced motivation.
You do not need to meet criteria for seasonal affective disorder to feel the effects of seasonal change. Many people experience a quieter, less obvious version.
You may still be going to work. You may still be caring for others. You may still be functioning.
But inside, everything may feel like it takes more effort.
How Counselling And Psychotherapy Can Help
Counselling and Psychotherapy can help you explore what happens emotionally and behaviourally as the seasons change.
You may begin to notice patterns such as:
- A dip in mood every autumn
- Anxiety increasing when routines become busier
- Comfort eating when evenings feel lonely
- Relationship tension when energy is low
- Reduced motivation linked to burnout
- Old grief or trauma surfacing around anniversaries or seasonal memories
- Increased irritability at home
- Feeling disconnected from yourself
Therapy gives space to understand these patterns without judgement. It can help you develop coping strategies, boundaries, emotional regulation skills and clearer communication.
For couples, seasonal stress can create more conflict, less intimacy and more misunderstanding. Couples Counselling and Marriage Counselling can help partners talk about stress, tiredness, parenting pressure, resentment, betrayal, communication breakdown or emotional distance in a more constructive way.
How Clinical Hypnotherapy, Clinical Medical Hypnotherapy And RTT May Help
Clinical Hypnotherapy uses focused attention and therapeutic suggestion to help the mind and body settle into a more receptive state for change.
Clinical Medical Hypnotherapy may be used alongside medical care for issues such as stress-related symptoms, pain, gut-brain patterns, sleep difficulty, anxiety, phobias, habits and certain health-related behaviours.
RTT, or Rapid Transformational Therapy, is an intensive therapeutic approach that explores the beliefs, emotional patterns and learned responses that may be contributing to current symptoms or behaviours.
These approaches may be considered for:
- Anxiety and stress
- Low confidence
- Sleep issues
- Emotional eating
- Sugar cravings
- Smoking and vaping
- Alcohol patterns
- Gambling or other addictive behaviours
- Trauma-related responses
- Fear, avoidance and self-sabotage
The aim is not to override your body. It is to help your nervous system feel safer, steadier and more able to respond differently.
What You Can Try This Fortnight
These suggestions are educational and general. If symptoms are severe, persistent or worsening, speak with your GP or a qualified mental health professional.
1. Get morning light early
Try to get outside within the first hour of waking, even on a cloudy Irish morning. Natural outdoor light is usually stronger than indoor light.
A short walk, standing by the door with a warm drink, or getting daylight on your commute may help your body clock receive a clearer morning signal.
2. Keep wake time consistent
Try to wake at a similar time most days. Your wake time helps anchor your circadian rhythm.
This can be especially helpful if you are sleeping longer but waking unrefreshed.
3. Reduce bright light late at night
In the evening, consider dimming lights and reducing screen brightness. Your brain reads light as information, not just illumination.
This is particularly important if you feel tired early, then wired later.
4. Balance blood sugar at breakfast
A breakfast with protein, fibre and healthy fats may help reduce cravings later in the day.
Examples include eggs with vegetables, Greek yoghurt with berries and seeds, porridge with nuts, or a balanced savoury breakfast.
5. Watch caffeine timing
Caffeine can linger for hours. If sleep is disrupted, consider keeping coffee earlier in the day and reducing afternoon intake gradually.
Do not stop suddenly if you drink a lot, as headaches and irritability can occur.
6. Notice seasonal self-soothing patterns
Ask yourself gently: “What do I reach for when I feel tired, flat, lonely or overwhelmed?”
This might be sugar, alcohol, vaping, scrolling, gambling, overworking, withdrawing or arguing.
Noticing the pattern is the first step towards changing it.
7. Name the season honestly
You might say, “This is a harder time of year for me, so I need steadier routines.”
That is not an excuse. It is self-awareness.
A recent client
A woman in Limerick noticed every October that her motivation dropped, her sleep became heavier, and her cravings for sweet foods increased. She blamed herself for “losing discipline”.
In therapy, we looked at her light exposure, work stress, grief anniversaries, blood sugar dips, evening loneliness and old beliefs about needing to cope alone. With Counselling, Registered Nutritionist input and Clinical Hypnotherapy for stress regulation, she began to understand the seasonal pattern differently.
Nothing dramatic had to happen overnight. Small changes, repeated consistently, helped her feel less trapped by the season.
When To Seek Extra Help

- Thoughts of self-harm
- Feeling hopeless
- Panic attacks
- Increasing alcohol, drug, gambling, food, smoking or vaping dependence
- Significant sleep disruption
- Relationship distress or conflict
- Eating disorder symptoms
- Symptoms affecting work, school, parenting or daily functioning
If you feel at immediate risk of harming yourself, contact emergency services or go to your nearest emergency department. In Ireland, you can contact your GP, out-of-hours GP service or emergency services on 112 or 999.
Frequently Asked Questions
1. Why do I feel more tired when the seasons change?
Reduced daylight can affect your body clock, melatonin timing, sleep quality, motivation and energy patterns. Stress, blood sugar, hormones, gut symptoms and mood can also contribute.
2. Can seasonal changes make anxiety worse?
Yes, for some people. Darker mornings, disrupted sleep, lower outdoor activity, school or work pressure, financial stress and less daylight can increase nervous system sensitivity.
3. Is seasonal affective disorder the same as depression?
Seasonal affective disorder is a pattern of depression that tends to occur at a similar time each year. You can still feel affected by seasonal change without having a formal diagnosis.
4. Can Counselling help with seasonal low mood?
Yes. Counselling can help you understand emotional patterns, stress triggers, relationship strain, motivation difficulties and coping behaviours that may worsen during certain times of year.
5. Can nutrition affect seasonal mood and energy?
Yes. Blood sugar balance, protein intake, caffeine, alcohol, gut health, inflammation, nutrient status and meal timing may all influence mood, cravings, sleep and energy.
6. Can Clinical Hypnotherapy or RTT help with seasonal patterns?
They may help some clients work with stress responses, sleep patterns, emotional eating, cravings, addictive behaviours, confidence and old beliefs that become more active during stressful seasons.
