How to Protect Your Sleep and Manage Stress: What a Sleep Therapist Actually Recommends
Sleep is the first thing to go when life gets full. Sleep therapist Denise Iordache on five research-backed strategies for protecting your rest, and why it's one of the most strategic things you can do.
When life gets full, sleep is usually the first thing to go. We push bedtime later, wake up earlier, and tell ourselves we'll catch up at the weekend. We rarely do. In my work as a sleep and stress therapist, I see this pattern constantly, and the toll it takes is far greater than most people realise.
Busy periods, disrupted routines, travel, social demands and emotional load all take a significant toll on sleep quality. Research consistently shows that irregular schedules, increased evening stimulation and higher stress levels are directly linked to shorter, lower-quality rest, which is a shame, because good quality sleep is one of the most important things you can do for your health, your focus and your ability to show up well in your business and life.
Why do we struggle when life gets busy?
Irregular bed and wake schedules (also known as social jetlag) are directly linked to poorer sleep quality and daytime impairment. Frequent travel and time-zone changes further disrupt the body's circadian rhythm; research points to light exposure, meal timing and direction of travel as key factors in how quickly the body realigns.
Alcohol and late, rich meals also harm sleep architecture in ways most people don't realise. Evening alcohol reduces REM sleep (the stage linked to memory and emotional processing) and fragments the night overall. Heavy meals close to bedtime increase awakenings and reflux-related sleep loss.
When life gets socially demanding
Social commitments, family time and a busier-than-usual schedule can raise stress levels in ways that directly affect sleep. Feeling emotionally activated before bed disturbs sleep onset and increases night-time wakefulness, which in turn affects how you process emotions and respond to pressure the following day.
Setting gentle boundaries, scheduling short recharge breaks during busy social days, and giving yourself permission to leave early when you need to all help preserve emotional bandwidth. You don't have to white-knuckle your way through periods of high demand. Protecting your energy is protecting your sleep.
Five strategies that actually help
1. Keep a festive wind-down ritual
Consistent pre-sleep cues (calm reading, warm herbal tea, dimmed lights) help your brain shift into rest mode regardless of what the day looked like. Structured nightly routines lower physiological stimulation and improve sleep onset. The body learns to recognise the signals.
2. Power down the screens before bed
Evening screen use (particularly scrolling social media, checking work emails or anything cognitively engaging) activates the prefrontal cortex and increases arousal in ways that delay sleep onset and reduce quality, even if total time in bed stays the same. Limiting stimulating screen use for around 60 minutes before bed, or shifting to passive low-stimulation activities, helps the brain transition to rest more easily.
3. Breathe and practice mindfulness to reduce stress
Short breathing practices and mindfulness reduce cortisol and pre-sleep hyperstimulation. Randomised controlled trials show that diaphragmatic breathing and brief mindfulness or yoga interventions lower stress markers and improve sleep quality. Even ten minutes of focused breathing can make a measurable difference.
4. Watch dinner timings
Aim to finish heavy meals two to three hours before bed. Evidence links late, calorie-dense meals with increased night awakenings and worsened sleep quality. If you need something before bed, lighter sleep-friendly options reduce digestive disturbance and help you sleep better.
5. Make your sleep space a sanctuary
Cool, dark and quiet rooms support consolidated sleep. Blackout curtains, eye masks and white noise for noisy environments can all reduce awakenings and stabilise sleep cycles. For those who travel frequently, controlling light exposure and timing meals strategically helps re-entrain the circadian clock more quickly after disruption.
Start with one change and notice the difference it makes. Small, consistent shifts in how you protect your rest compound quickly, and the version of you that's properly rested will always outperform the one running on empty.
