HR Learning of the Month: Sleep Well, Feel Well
If you’ve ever tossed and turned after a stressful day — or felt off emotionally after
a poor night’s sleep — you’ve experienced the powerful connection between mood and
rest. The good news? Small shifts in your daily habits can help you feel more grounded,
energized and emotionally balanced.
Let’s explore three simple (and proven) ways to support your mood and, in turn, improve your sleep:
How sleep affects mood
- Sleep deprivation = emotional instability
- Lack of sleep reduces activity in the brain’s prefrontal cortex—the part that helps us stay calm, focused, and positive.
- Increased anxiety and irritability: Poor sleep raises cortisol (stress hormone) levels and inhibits production of mood-regulating chemicals like serotonin and dopamine.
- Lower resilience to stress: Without restorative sleep, even small challenges can feel overwhelming.
- Mood disorders can worsen: Chronic insomnia is a risk factor for anxiety and depression and can make mood management strategies (like mindfulness or therapy) less effective.
How mood affects sleep
- Anxiety = trouble falling asleep: Racing thoughts or overthinking keep the brain in a hyper-alert state.
- Depression disrupts sleep cycles: People may experience either insomnia or hypersomnia, throwing off the body’s natural rhythms.
- Mood dysregulation = fragmented sleep: Elevated stress can lead to frequent nighttime waking or lighter, less restorative rest.
Try this, depending on your schedule
- Working a 9-5? Build a wind-down window 30-60
minutes before bed. Dim lights, power down screens, and swap scrolling for journalling or gentle stretching. - Working late or on shifts? Use visual cues like dim lighting and
calming scents to signal “sleep mode” even during the day. - Always on the go? Take a personalized energy audit of your current daily routine.
What’s one thing you can remove, reduce, or reframe to
support and replenish your energy?
