The clock on the control room wall read 02:17 AM. Outside, winter rain tapped softly against the building windows, while inside, the only light came from rows of glowing monitors and blinking surveillance panels.

Sally rubbed her eyes and leaned back in her chair. It had been a long week of night shifts. The coffee next to her had already gone cold, and despite the constant activity on the screens in front of her, exhaustion hung over her like a heavy blanket.

At first, she thought she was just tired.

But lately, it felt different.

She struggled to concentrate during the quieter hours of the night. Small tasks felt harder than usual. She was irritable, drained, and constantly low on energy. Even on her off days, all she wanted to do was sleep.

One evening during shift handover, her colleague Lerato noticed it immediately.

“You look finished,” she joked lightly.

Sally laughed. “Winter is winning.”

But the truth was that many control room personnel quietly experienced the same thing during the colder months. Long hours indoors, limited sunlight, little movement, and rotating shifts create the perfect environment for the winter blues and sometimes even Seasonal Affective Disorder.

A week later, the company wellness officer visited the control room and explained something that caught Sally’s attention: the human body depends heavily on light to regulate the Circadian Rhythm, the internal system that controls sleep, mood, and alertness.

In winter, with shorter days and less sunlight, that rhythm can become disrupted. Add night shifts and hours in a dimly lit control room, and the body starts feeling constantly out of sync.

For the first time, Sally realized there was a reason she felt the way she did.

The team decided to make a few small changes.

Nothing dramatic.

Just practical adjustments.

They started taking short movement breaks every hour. Sometimes it was just a quick walk down the corridor or a few stretches beside the workstation.

Surprisingly, those few minutes helped everyone feel more awake and focused.

Management also introduced brighter daylight-style desk lamps in parts of the control room. The difference was noticeable within days. The room no longer felt quite as heavy during night shifts.

Sally also changed her routine at home. Instead of scrolling endlessly on her phone before sleeping, she created a proper wind-down routine after work. Dark curtains, less caffeine near the end of shifts, and consistent sleep times slowly helped her energy return.

The winter nights were still long.

The monitors still glowed.

The radios still crackled through the early hours.

But something had changed.

The control room no longer felt like a place people survived until sunrise. It became an environment where well-being mattered just as much as vigilance. And in an industry where focus can make all the difference, that mattered more than anyone realized.

3 Simple Ways Control Room Personnel Can Fight the Winter Blues

Increase Light Exposure

Use bright or daylight-spectrum lighting where possible and spend a few minutes outside during breaks to help reset your body clock.

Move More During Shifts

Short “micro-breaks” involving stretching or walking can improve concentration, circulation, and energy levels.

Protect Your Sleep Routine

Maintain consistent sleeping habits, especially after night shifts, and create a dark, quiet environment for proper rest.

Winter may test even the best control room operators, but small changes can make a big difference.

Better light, more movement, and proper rest can help you stay focused, alert, and in control - no matter how long the night feels.
