Sleep Top Tips: Your Guide to a Better Night's Rest

How much sleep do you need?

Most healthy adults need at least 7 hours of sleep a night, and most people don’t need more than 8 — though quality matters just as much as quantity, so waking up feeling rested is as important as the number of hours on the clock. Needs also vary by age: children and teenagers generally need more sleep than adults, while older adults often sleep lightly and wake more often, even if they don’t need much less overall.

Why do we sleep?

While the exact reasons for sleep remain a mystery, it’s clear that sleep is crucial for survival. It restores the body, regulates mood, and boosts essential functions such as memory, immune response, and reaction times.

Investing in quality sleep is investing in your overall health. Let’s explore some simple, actionable tips to help you get a good night’s rest.

Keep a consistent sleep schedule

Going to bed and waking up at roughly the same time every day, including weekends, is one of the most effective ways to sleep better, according to both NHS and Mayo Clinic guidance. A regular rhythm helps steady your body clock, so falling asleep and waking up both become easier over time.

What is your chronotype?

Your chronotype is your body’s natural preference for when to sleep and when to be alert — some people are naturally "morning types" who wake early and feel sharpest earlier in the day, while "evening types" naturally feel more alert later on. Working with your chronotype, rather than fighting it, by aligning your sleep schedule and daily routine to your natural preference where you can, tends to make for easier, better-quality sleep.

4 essential tips for better sleep

1. Switch to an alarm clock and remove your phone from the bedroom

Good sleep hygiene starts with reducing screen time, especially before bed. The blue light emitted by phones, TVs, and other devices can interfere with your body’s natural sleep cycle by suppressing melatonin, the hormone that makes you feel sleepy.

Here’s how to improve your sleep environment:

• Avoid screens at least an hour before bed

• Replace your phone with a traditional alarm clock to resist the temptation of late-night scrolling

• Keep your bedroom dark and quiet to encourage better rest

Optimise your bedroom environment

Beyond a dark, quiet room, a few other environmental factors make a real difference, according to NHS guidance:

• Keep the room cool — a temperature that’s too warm makes it harder to fall and stay asleep
• Choose comfortable, breathable bedding suited to the season
• Block out light fully with curtains or blinds, or use an eye mask if needed
• Use earplugs or a fan for background noise if your bedroom isn’t fully quiet
• Write down tomorrow’s tasks or worries before bed, so your mind doesn’t hold onto them overnight
• Try meditation, breathing exercises, reading or calming music instead of scrolling on a screen
• Keep a consistent wind-down routine so your body learns to associate it with sleep
• You’ve had persistent trouble falling or staying asleep for several weeks or more
• Poor sleep is affecting your mood, concentration, or day-to-day life
• You suspect an underlying cause, such as anxiety, stress, a thyroid problem, or chronic pain

2. Keep a sleep diary

Tracking your sleep patterns can help identify habits or triggers that affect your rest. Keep a diary for at least two weeks, noting:

• What time you went to bed and woke up

• What you ate, drank, or did before bedtime

• How long it took to fall asleep and any night time awakenings

• How you felt in the morning

By comparing your daily activities with your sleep quality, you can make meaningful changes to improve your rest.

3. Watch your alcohol and caffeine intake

What you consume plays a significant role in how well you sleep:

• Alcohol: Drinking before bed can lead to poor-quality, fragmented sleep as your body metabolises the alcohol during the night

• Caffeine: While some people tolerate caffeine late in the day, others find it disrupts their ability to fall asleep. If you’re sensitive, avoid caffeinated drinks after midday and opt for herbal teas instead

Studies show that caffeine can affect sleep patterns, particularly in those with specific genetic traits. When in doubt, it’s best to limit your intake during the afternoon and evening.

Wind down and manage stress before bed

A calming pre-bed routine helps quieten a busy mind, according to Mayo Clinic:

If stress or anxious thoughts are a big part of what’s keeping you up, it’s worth tackling that directly — our guides on anxiety and overthinking and managing stress cover practical techniques that can help both your sleep and how you feel during the day.

Get active during the day

Regular physical activity supports deeper, better-quality sleep, according to NHS and Mayo Clinic guidance — even a short daily walk can help. Just be mindful of timing: vigorous exercise too close to bedtime can leave you feeling too alert to drop off, so where possible save the most intense sessions for earlier in the day. Our guide to getting active has simple ways to build more movement into your day.

4. Speak to a GP about persistent sleep issues

If your sleeplessness is caused by underlying conditions such as anxiety, stress, thyroid problems, or chronic pain, it’s important to seek professional advice.

As a general guide, Mayo Clinic advises contacting your health care provider if you often have trouble sleeping — identifying and treating any underlying cause can make a real difference. It’s worth booking an appointment if:
