How Lifestyle Stress Affects Sleep, and What Helps

You're exhausted by 10pm, you get into bed, and your brain decides it's the perfect time to replay a meeting, plan tomorrow and remember an email you forgot to send. Stress and sleep are closely tied, and for a lot of people a stressful patch is the first thing that knocks their sleep off course.

This guide explains how stress affects sleep, the signs it's happening to you and the practical steps that help you wind down.

How stress keeps you awake

When you're under pressure, your body releases stress hormones such as adrenaline and cortisol. They're useful when you need to react quickly, and they make you more alert. The trouble comes when that alert state carries on into the evening.

Normally, cortisol is lowest around bedtime and rises towards the morning to help you wake up. Ongoing stress can blur that pattern, so your body stays more switched on when you want to sleep. Poor sleep then makes the next day feel more stressful, and the cycle continues. The NHS lists difficulty sleeping as one of the most common signs of stress.

Everyday causes of stress-related poor sleep

Work that follows you home

Long days, deadlines and checking messages at night keep your brain in work mode long after you've logged off.

Irregular hours

Late nights, early starts and different bedtimes through the week confuse your body clock, which makes it harder to feel sleepy at the right time.

Screens late at night

Scrolling in bed keeps your mind busy, and bright screens late in the evening can delay the point at which you feel sleepy.

Money, family and life admin

Personal worries are often the ones that surface the moment the lights go off.

Signs stress is affecting your sleep

• You feel tired but wired at bedtime.
• Your mind races when you try to sleep.
• You wake in the night, often at the same time, and start thinking about the day ahead.
• You wake up feeling unrefreshed, then rely on caffeine to get going.
• You're more irritable or find it harder to concentrate during the day.

What helps you wind down

Give yourself a wind-down hour

Your body needs a signal that the day is over. Dim the lights, put your phone away and do something calm: reading, a warm shower, gentle stretching or slow breathing. The NHS Every Mind Matters sleep advice suggests the same kind of routine.

Park your worries before bed

Spend five minutes earlier in the evening writing down what's on your mind and the next step for each item. It's easier to let go of a worry when it's on paper.

Keep regular hours

Going to bed and getting up at the same times, including at weekends, is one of the most effective things you can do for your sleep.

Move during the day

Regular exercise helps you handle stress and tends to improve sleep. A walk at lunchtime counts.

Watch the caffeine and alcohol

Caffeine can stay in your system for hours, so try to stop after lunch. Alcohol might help you nod off, but it tends to make sleep lighter and more broken later in the night.

Make your bedroom work for sleep

Dark, quiet and cool. Blackout blinds, earplugs and a slightly open window all help.

Where a sleep supplement fits

If you've sorted the basics and still struggle to switch off, a sleep supplement can be part of your evening routine. HIRO Sleep was made for exactly this: trouble falling asleep, a brain that won't switch off and waking in the night.

Its hero ingredient is Levagen®, a clinically trialled natural ingredient that has been shown to reduce anxiety and improve sleep. In a placebo-controlled trial on sleep, adults taking it reported improvements in how they slept (Rao et al., Sleep Science and Practice, 2021). HIRO Sleep combines it with:

• Ashwagandha (KSM-66®), 150mg. An adaptogenic root studied for stress and sleep. In a placebo-controlled study, adults taking KSM-66 ashwagandha reported lower stress and better sleep quality (Salve et al., Cureus, 2019).
• Magnesium, 112.5mg, and chamomile flower, 75mg, both known for their relaxing qualities.

It's designed to help you fall asleep faster, stay asleep longer and wake up sharper. Take it as part of your wind-down routine. It works best alongside the habits above.

When to get help

If stress is affecting your sleep for weeks at a time, or you feel anxious or low most days, talk to your GP. They can help with both, and in England you can also refer yourself to NHS talking therapies for stress and anxiety. If you're pregnant, breastfeeding, have a thyroid condition, take medication or have a health condition, check with your GP or pharmacist before taking a supplement containing ashwagandha.

The short version

Stress keeps your body in an alert state that makes sleep harder. A wind-down hour, regular hours, less late caffeine and a bedroom set up for sleep make the biggest difference. If you'd like extra support, you can find HIRO Sleep in our sleep collection, and the Twin Pack brings the cost down if it becomes part of your routine.

Frequently asked questions

Why do I wake up at 3am when I'm stressed?

Sleep gets lighter in the second half of the night, so you're more likely to stir. If stress has you on alert, it's easier to wake fully and start thinking. Getting up for a few minutes in dim light, rather than lying there worrying, can help you settle again.

Can I take HIRO Sleep every night?

It's designed to be part of a regular evening routine. Follow the directions on the pack and don't exceed the recommended serving.

Is it better to fix stress or fix sleep first?

Work on both. Better sleep makes stress easier to handle, and lower stress makes sleep easier. A simple routine is the best place to start.
