Sleep is a contributing factor to our health!
Sleep is one of those everyday things we often take for granted until we are not getting enough of it.
A few poor nights can leave us feeling foggy, flat and short-tempered. But when lack of sleep becomes a regular pattern, it can have a much wider impact on our wellbeing. It is not just about feeling tired. Good quality sleep gives the body time to repair, restore and reset.
I learnt this lesson early in my nursing years. Shift work was part of the job, and like many nurses, I became used to sleeping at odd times and working when most people were tucked up in bed. At the time, I thought I was coping well. I could fall asleep almost anywhere and keep going when I needed to. But looking back, I can see that my body was probably asking for more rest than I was giving it.
Most adults need around eight hours of sleep, give or take. Some need a little more, some a little less, but very few of us thrive on broken or consistently shortened sleep. Research has also shown that working through the night, or regularly sleeping out of rhythm with daylight, can disrupt the body in ways we may not notice straight away.
So, what can happen when we regularly miss out on good quality sleep?
1. Your skin may show it
There is a reason people talk about beauty sleep. When we sleep, the body does important repair work, and this includes the skin. Too little sleep can leave skin looking dull, tired or less resilient. Over time, it may also make it harder for the skin to recover from everyday stressors such as sun exposure, dehydration and inflammation.
2. Your thinking can become cloudy
A tired brain is not a sharp brain. Poor sleep can affect concentration, memory, decision-making and our ability to respond calmly to everyday situations. Even simple tasks can feel harder when the mind has not had time to properly rest and sort through the day.
3. Your body may become more stressed
When we do not sleep well, the body can produce more stress hormones. This can add to inflammation and place pressure on the immune system. While we sleep, the body is busy doing many behind-the-scenes jobs, including producing proteins that help protect us from infection and support recovery.
4. Your mood can take a hit
Feeling weepy, irritable, unmotivated or emotionally stretched can sometimes be connected to poor sleep. Sleep gives the brain time to process the day, regulate emotions and clear the mental clutter. Without that nightly reset, everything can feel heavier than it really is.
5. Your appetite and cravings may change
When the brain is tired, it may go looking for energy in the quickest place it can find it. Food! This can mean stronger cravings, late-night snacking or reaching for sweet foods when we are already running low on willpower. Poor sleep can also affect blood sugar regulation, which may influence energy, appetite and weight over time.
6. Your impulse control may drop
Most of us have made a strange online purchase or raided the pantry late at night. When we are tired, our ability to pause, think clearly and make good choices can be reduced. Better sleep can support better self-control, clearer thinking and healthier daily habits.
What can you do to help the sandman bring you a dream?
Start with the simple things. They may sound basic, but they matter.
Avoid naps during the day if they make it harder to sleep at night.
Keep caffeine, alcohol, heavy meals and sugary foods away from bedtime where possible.
Move your body regularly, but try not to do intense exercise right before bed.
Make your bed comfortable and your bedroom a restful space.
Keep the room cool, quiet and well ventilated.
Reduce distracting noise and light.
Give yourself time to unwind before bed.
Try not to take the day’s worries under the covers with you.
Sleep is not a luxury. It is one of the foundations of good health. So perhaps the kindest thing you can do for your body tonight is to let it rest.
