Sleep is more than just rest; it’s a crucial function that keeps our bodies and minds in top shape. Dr. Stuart explains why quality sleep matters and how to improve it.

The Importance of Sleep

Sleep plays a fundamental role in brain function, memory consolidation, and immune system support. Dr. Stuart emphasises, “It helps to regulate emotions and maintain overall health. Every animal needs sleep to regenerate and consolidate energy.” During sleep, the brain clears toxins and restores itself. Without enough rest, cognitive function declines, and mood swings become common.

Sleep and ADHD

Children with ADHD often struggle with sleep because they are highly energetic and easily distracted. “Sleep falls off the radar for kids with ADHD, just like they might forget to eat because they’re too preoccupied,” Dr. Stuart explains. Parents should ensure all potential medical factors affecting sleep are properly evaluated.

Signs of Sleep Deprivation

The most obvious sign of lack of sleep is tiredness, but there are other indicators. “We often mask sleep deprivation with caffeine and stimulants,” says Dr. Stuart. “But that doesn’t replace proper rest.”

Other symptoms include:

  • Irritability
  • Lack of focus
  • Slower reaction times
  • Reduced immune function

Some people experience spontaneous naps throughout the day but still feel exhausted. Dr Stuart explains, “This can become a learned behaviour where the body adapts to an unhealthy pattern. A sleep study and consultation with a sleep physician can help reset these habits.”

How Much Sleep Do You Need?

The amount of sleep varies by age:

  • Newborns (0-3 months): Up to 17 hours
  • Teens: 8-10 hours
  • Adults: 7-9 hours
  • Older Adults: 7-8 hours

However, Dr. Stuart notes, “It’s not just about quantity, but quality. Poor sleep, even for eight hours, can leave you feeling unrefreshed.”

Sleep Myths and Misconceptions

One of the biggest myths? That you can function well on four hours of sleep. “Nobody thrives on that amount,” says Dr. Stuart. “People who live longer tend to sleep better and longer.” Another misconception is that you can “catch up” on sleep over the weekend. Dr. Stuart explains, “You may feel better, but there’s a lasting deficit from chronic sleep deprivation.”

The Impact of Shift Work on Sleep

For shift workers and FIFO employees, disrupted sleep can be a major challenge. Dr Stuart recalls his experience as a junior doctor: “Flipping from day to night shifts is incredibly difficult. You’re not at your best, which is concerning in high-stakes jobs.” Some shift workers try to maintain their night shift routine even when home, but this can be impractical for family life.

Alternatives to Sleeping Pills

Many turn to medication, but Dr. Stuart warns, “Sleeping tablets are highly addictive and don’t work the way people expect.” Instead, he recommends alternatives like melatonin: “Melatonin helps signal to the brain that it’s time to sleep. It can be useful when adjusting to a new sleep pattern, but consult a doctor before use.”

Sleep Apnea and Other Sleep Disorders

Another common but overlooked sleep issue is sleep apnea. “Many people with sleep apnea think they’re sleeping through the night, but their sleep quality is poor because they repeatedly stop breathing,” Dr. Stuart says. This condition can lead to daytime exhaustion, increased health risks, and reduced cognitive function.

For those experiencing excessive daytime sleepiness, narcolepsy might be a concern. “Narcolepsy causes people to fall asleep suddenly, even in the middle of a conversation,” explains Dr. Stuart. This condition requires a specialist diagnosis and treatment plan.

When to Seek Help

If sleep problems persist, a sleep study may be needed. “If someone has struggled with sleep for years, it’s worth seeing a sleep physician,” says Dr. Stuart. Quality sleep is essential for good health. Making small changes to improve your sleep can have long-term benefits for your well-being.
