A welcome dose of sunshine is often enough to bring a smile to the face of even the most hardened employee, but springtime isn’t always the anecdote for the workplace blahs.

Here are a few ways the warmer weather can have a negative impact on employees:

Mood swings: As the weather warms up and sunny days increase, employees may experience shifts in mood and energy levels. Many may feel more optimistic and motivated; others may struggle with mood swings and irritability, especially if they feel like they’re being cooped up indoors or overwhelmed by work responsibilities.

Seasonal allergies: Springtime allergies caused by pollen, dust and other environmental allergens can affect our physical health and comfort. Allergy symptoms such as sneezing, congestion and itchy eyes can be distracting and debilitating, making it challenging for employees to focus and function effectively at work.

Decreased productivity: Are your coworkers staring out the window when you’re making a presentation? Get used to it. Employees often find it challenging to stay focused and productive at work when distracted by thoughts of enjoying the weather outside. Spring fever can lead to daydreaming, procrastination and difficulty concentrating on tasks, which may decrease productivity and performance.

Increased absenteeism: Some employees may be more inclined to call in sick or take unplanned time off from work during the spring months. They may cite allergies, seasonal illnesses or personal reasons for their absences, but spring fever-related distractions and a desire to enjoy the outdoors can also increase absenteeism rates. We’re not saying employees are dishonest, but a couple of tickets to an afternoon Sox game are often the cause of some springtime aches and pains.

Sleeping issues: Changes in daylight patterns and circadian rhythms during the spring can disrupt sleep patterns, leading to difficulty falling asleep or staying asleep at night. And of course, a lack of sleep can have a negative impact on employees’ cognitive function, energy levels and mood throughout the day.

Increased stress: Spring fever-related distractions and the usual work responsibilities and deadlines can contribute to higher stress levels. The pressure to balance work commitments with personal desires to enjoy the spring season – and getting the kids to baseball on time after work – can lead to feelings of overwhelm, anxiety and burnout.

So how do employers combat the springtime maladies? Sheila Hansford, a social worker in Miami, Florida, who specializes in corporate work strategies, says the first thing managers need to do is acknowledge the potential changes in their employees’ state of mind.

“Bosses should consider outdoor team-building, some flexibility with work schedules and if possible, more remote work options,” Hansford says. “Even suggesting short breaks so your people can enjoy the sunshine can be a great way to build some positive vibes at work, which can lead to a much more productive work environment.”
