Most of us think of sleep as something we “decide” to do — we go to bed, close our eyes, and hope sleep arrives.

But biologically, sleep is less about choice and more about pressure. Sleep pressure is your body’s natural drive to sleep. Understanding this can explain why sometimes you drift off easily and on others you lie awake.

In a previous post, we discussed “Sleep Hygiene” so today we’ll explore what sleep pressure is, how it builds and fades, and habits that influence it. 

What is sleep pressure? 

Sleep pressure is your body’s internal “sleep hunger.”

From the moment you wake up, chemicals begin building in your brain — most notably adenosine. The longer you’re awake, the more adenosine accumulates, increasing your drive to sleep. By evening, sleep pressure is usually strong enough to help you sleep.

When you go to sleep, your body clears adenosine away. By morning, your sleep pressure is low again, and the cycle begins again! 

This helps explain why, for example:

Waking up early can make falling asleep easier the following night- longer time for sleep pressure to build up. 

A full night’s sleep helps you feel refreshed-  because sleep pressure resets

What Decreases Sleep Pressure? 

Although sleep pressure builds throughout the day, certain habits can reduce it or interfere with how it works. Here are a few of the most common:

1. Naps

Napping can be a double-edged sword.

Short naps (10–20 minutes) may be refreshing, but any sleep — even brief — lowers sleep pressure. If you nap late in the day or nap for too long, you’re essentially “snacking” on sleep, which may leave you lying awake at bedtime with insufficient pressure to push you into slumber.

2. Caffeine

Caffeine doesn’t remove sleep pressure — it blocks your brain’s ability to detect adenosine. Think of caffeine like a hand placed firmly over your sleep pressure gauge. The adenosine is still there, but you don’t feel it until the caffeine wears off. That’s why a late-afternoon coffee can leave you wired at night, even if you drink it “all the time” and feel used to it.

3. Screen Time

Screens don’t directly reduce sleep pressure, but they can disrupt its partnership with your body clock, also known as the circadian rhythm.

Bright light (especially blue light) signals to your brain that it’s daytime, slowing down the natural evening wind-down. Mentally stimulating content — scrolling, gaming, intense shows — also keeps your brain “awake,” making it harder for sleep pressure to take the lead.

How to work for your sleep drive?

1. Wake up at the same time every day

This helps anchor your circadian rhythm and allows sleep pressure to build predictably throughout the day.

2. Get light exposure in the morning

Natural light is a powerful signal to your internal clock, helping stabilise the sleep-wake cycle.

3. Keep naps early and short

If you nap, aim for before 2pm and stick to 10–20 minutes.

4. Watch your caffeine timing

Try to avoid caffeine after the early afternoon. Let your sleep pressure build without interference.

5. Create a wind-down routine

A consistent, calming ritual helps your brain shift gears, allowing sleep pressure and your circadian rhythm to work together rather than compete with stimulation and stress.

6. Practice acceptance when sleep doesn’t come easily

Instead of “trying” to sleep, try focusing on restfulness — gentle breathing, a soothing activity, or simply lying quietly. This reduces mental arousal and allows sleep pressure to do its job naturally when it comes.

Australians love their pets, but sleeping with them could be stealing hours of precious rest every year.

According to a recent survey, one in five Aussies (22%) let a pet sleep in their bed. Of those, 92% are woken at least once a week, and nearly a third are disturbed several times a week. For some, it’s every night. That adds up to an average of 1.3 hours of lost sleep per week or almost 70 hours a year.

“They take over the bed”

Sleep expert Amanda Slinger, admits she’s experienced it herself. “Whenever they are in the bed with us, they take over. We never get the sleep we’d like.”

Pets can wake owners by moving, licking, barking, meowing or simply generating extra heat under the covers. And while these disturbances may not always wake us fully, Amanda warns they can still disrupt deep sleep cycles.

Why lost sleep matters

Even small disturbances can have a ripple effect. “Sleep affects everything, emotional resilience, decision-making, reaction time, even how you communicate,” Amanda explains. “When I haven’t slept well, I’m grumpy and I don’t want to see anyone.”

The upside of sharing your bed

It’s not all bad news. Many people find comfort and reduced anxiety when their pet is close by.

“Sometimes I’ll grab one of my cats for a cuddle to help me get back to sleep,” Amanda says. “They can be hugely comforting.”

The survey also revealed women are more likely than men to share their bed with a pet (27% compared to 16%.) For some, especially those living alone, the presence of a pet offers an extra sense of security.

Tips for better rest with pets

Amanda says the choice to share your bed is personal, but awareness is key. Track your sleep with a wearable device, or simply notice how you feel in the morning. If you’re constantly tired, consider alternatives such as:

• Letting pets join only in the morning for cuddles
• Providing them with a cosy bed nearby
• Creating a calming bedtime routine

And if you do wake during the night, Amanda recommends having a “toolbox” of relaxation aids like a quiet podcast or soft music at low volume to help you drift back off.

Morning habits matter most

Amanda stresses that the best way to protect your sleep isn’t just about bedtime, it starts in the morning.

“Your morning routine is the most important for setting your body clock,” she says.

Her top two “morning anchors” are:

Get sunlight for 15–20 minutes, even on cloudy days.

Wake up at the same time every day, including weekends.

If you need extra rest, try a short afternoon nap instead of sleeping in.

The Takeaway

Sharing your bed with a pet can be comforting, but it may be quietly costing you dozens of hours of rest each year. The key is knowing whether the benefits outweigh the sleep disruptions, and adjusting your habits to get the best of both worlds.

Sleep hygiene is a term that I hear thrown around regularly. But what is sleep hygiene, and what are four elements that support sleep?

Sleep hygiene refers to good sleep practices that protect sleep and support overall nighttime rest. There are a variety of tools that can support your sleep — these tips are just some examples that can support you in your sleep wellbeing.

Four Sleep Hygiene Tips that support sleep: 

1. Keeping your bed for sleep

Your bed should be a place your body associates with rest and sleep, not with wakeful activities. If you’re watching TV, scrolling your phone, or even studying in bed, your brain stops linking it to sleep. Over time, try reserving your bed for sleep.

2. Have a routine

Having a consistent routine signals to your body that it’s time to get ready to sleep. Going to bed and waking up at the same time each day helps regulate your internal body clock. A familiar evening ritual, like reading or a warm shower, can prepare your mind and body for sleep.

3. Stop eating before bed 

Eating late at night can activate your digestive system and make it harder for your body to relax. Heavy or rich foods especially can disrupt your ability to fall or stay asleep. Try to have your last meal or snack at least an hour before you go to bed.

4. Avoid (unnecessary) drug intake

Some substances, like caffeine, nicotine, or alcohol, can interfere with your sleep cycle. Additionally, medications and supplements can impact sleep, depending on when they’re taken. It’s helpful to review what you’re consuming in the hours leading up to sleep, perhaps with help from your GP, and consider anything that isn’t essential.

The Role of Acceptance

I used to love youth camps — except for one thing, I couldn’t get to sleep. I would lie down, be tired, and then think about how I couldn’t get to sleep on youth camps. I would blame the snoring of a friend, the discomfort of the bed, the light from the bathroom… but I couldn’t seem to get my thoughts to focus on anything other than trying to get to sleep.

After a few camps, I decided to accept that I wouldn’t get a good sleep at youth camps. I put my earphones in, focused on the music and accepted that I wasn’t going to sleep well that night. Somehow, I fell asleep much earlier.

If sleep hygiene practical tips don’t seem to support sleep for you; consider the worry and anxiety that may be keeping you awake.
