Seasonal Depression in the Transport Industry: Why Awareness Matters All Year Round

Seasonal Depression in the Transport Industry: Why Awareness Matters All Year Round

As the final weeks of autumn arrive and the first signs of winter set in, many people may notice a shift in their mood and energy levels. For some, this shift becomes much more than just a dislike of cold weather. Seasonal Affective Disorder (SAD) is a type of depression linked to changes in daylight. It can have a significant impact on daily life, especially for those working in demanding, high-pressure environments.

In the UK transport industry, seasonal depression and wider mental health struggles intersect in ways that deserve serious attention.

What Is Seasonal Depression?

Seasonal depression, or SAD, typically begins in late autumn or early winter. As days become shorter and sunlight declines, people with SAD experience changes in their body chemistry and energy levels. This condition is more than feeling “a bit low in winter”, it’s a recognised form of depression that can be debilitating.

Common symptoms include:

  • Persistent low mood
  • Loss of pleasure or interest in everyday activities
  • Irritability
  • Feelings of worthlessness, guilt or despair
  • Low energy or excessive daytime sleepiness
  • Sleeping longer than usual or having difficulty waking
  • Craving carbohydrates and gaining weight
  • Difficulty concentrating
  • Reduced sex drive

For some, these symptoms become severe enough to significantly disrupt work, relationships and daily activities.

What Causes Seasonal Depression (SAD)?

The causes of seasonal depression are complex but often linked to changes in light exposure:

Melatonin Levels

Melatonin is a hormone that regulates sleep. In people with SAD, winter darkness can trigger higher-than-normal levels, leading to fatigue and sluggishness.

Serotonin Levels

Serotonin affects mood, appetite and sleep. Reduced sunlight can lower serotonin production, contributing to depression.

Body Clock Disruption

Our internal circadian rhythm relies on daylight cues. Shorter days can cause this clock to fall out of sync, triggering symptoms of SAD.

Seasonal Depression in the Transport Industry: Why the Impact Is Greater

The transport sector is uniquely vulnerable to mental health challenges and SAD can intensify these existing pressures.

Long and Irregular Hours

Early starts, night shifts and extended periods away from home disrupt sleep patterns and limit exposure to natural light, key factors that worsen SAD symptoms.

Isolation

Many transport workers, especially HGV drivers, spend long hours alone. During winter, this isolation can deepen feelings of hopelessness or disconnect.

High Work Pressure

Tight schedules, traffic delays, safety demands and job strain all contribute to higher stress levels.

In the UK, these conditions have created a concerning trend. Research from Mates in Mind found that:

  • HGV drivers have a 20% higher suicide rate than the national average
  • Van drivers have a 25% higher suicide rate than average

When combined with seasonal depression, these pressures create a heightened mental health risk.

The Role of Night-Time Work

A significant portion of the transport and storage workforce is part of the night-time economy. More than 30% of workers in transport, agriculture, forestry, fishing and parts of healthcare work during night hours, further reducing exposure to natural daylight.

Night shifts, reduced sleep quality and limited social interaction all increase vulnerability to depression, anxiety and burnout, especially during the winter months.

Men’s Mental Health in Transport

The transport industry is heavily male-dominated, and men already face substantial barriers when it comes to mental health:

  • 1 in 6 men in the UK has a diagnosed mental health issue
  • Up to 50% of men report experiencing poor mental health at some point
  • 40% of men have never spoken to anyone about their mental health
  • 3 in 4 suicides in the UK are by men

Stigma, cultural expectations and fear of being seen as “weak” often prevent men from seeking help. When seasonal depression hits, these issues can be magnified.

Treatments and Support Options for Seasonal Depression

There are effective treatments for SAD, and recognising symptoms early can make a huge difference.

Lifestyle Measures

  • Maximise exposure to natural daylight
  • Take regular exercise
  • Practice stress-management techniques
  • Maintain a consistent sleep schedule

Light Therapy

Using a specialised light box can simulate natural daylight and help regulate melatonin and serotonin levels.

Talking Therapies

Cognitive Behavioural Therapy (CBT), counselling or group support can help address patterns of thought and behaviour associated with SAD.

Breaking the Silence

Awareness of mental health often peaks around national events such as World Mental Health Day or Suicide Prevention Month, but struggles don’t disappear outside these dates.

Many people know of SAD, but few understand its depth, impact or how severely it can affect someone’s ability to function. For transport professionals already facing workplace pressures, the combination can be overwhelming.

It’s important to remember, you’re not alone, you don’t need to wait until crisis point to seek help and conversations about mental health should happen all year round.

At EOS Training, we encourage open conversations, early support and safe spaces for workers to talk about how they feel, every season of the year.
