Sleep is often treated as something we can sacrifice when life gets busy. A late night here, an early morning there and sometimes, we convince ourselves that we can simply get used to it.
But getting used to feeling tired does not necessarily mean your body has adapted to functioning well on less sleep.
Let’s look at a common sleep myth.
Myth: “You can train your body to function normally on very little sleep.”
Fact: While some people may feel that they can manage on little sleep, regularly getting less sleep than your body needs can affect how you function during the day.
Insufficient sleep can affect:
- Concentration and attention: making it harder to stay focused.
- Memory and learning: sleep plays an important role in processing and retaining information.
- Mood: inadequate sleep can affect emotional regulation and how you respond to everyday situations.
- Reaction time: tiredness can slow responses and affect alertness.
- Physical health: consistently poor sleep is associated with a range of health concerns over time.
How much sleep do you actually need?
Sleep needs vary by age and individual circumstances. For most adults, around 7–9 hours of sleep per night is generally recommended.
However, sleep quality matters too. Getting enough hours does not always mean you are getting restorative sleep.
What if you regularly struggle to sleep?
Occasional difficulty sleeping can happen. Stress, changes in routine, illness, travel and other factors can temporarily affect sleep.
But if difficulty sleeping, waking frequently, or feeling excessively tired during the day becomes persistent, it is worth paying attention to the pattern and discussing it with a qualified healthcare professional where appropriate.
Getting used to tiredness isn’t the same as getting enough sleep
You may become familiar with functioning while tired. You may even feel that you are “fine” after several nights of limited sleep.
That doesn’t necessarily mean your body is receiving what it needs.
Sleep is not simply time when nothing is happening. It is an important part of maintaining physical and mental function.
Key takeaway: Don’t measure your sleep only by how well you think you can push through the day. Pay attention to how consistently you sleep, how rested you feel and whether poor sleep is becoming a pattern.
Give your body the opportunity to rest.
