The Growing Problem: Insomnia and Sleep Apnoea

Data suggests a concerning trend: more and more Australians are struggling with both insomnia and sleep apnoea. Insomnia, characterised by difficulty falling asleep, staying asleep, or experiencing non-restorative sleep, can be triggered by stress, anxiety, poor sleep hygiene, and underlying medical conditions. Sleep apnoea, on the other hand, involves repeated interruptions in breathing during sleep, often due to a blocked airway. This leads to fragmented sleep and reduced oxygen levels, putting significant strain on the cardiovascular system.

The causes are multifaceted. Modern lifestyles, with their 24/7 connectivity and demanding work schedules, contribute to heightened stress levels and disrupted sleep patterns. Increased screen time, especially before bed, interferes with melatonin production, a hormone essential for regulating sleep. And, in some cases, underlying medical conditions or medications can play a role.

The Health Consequences of Sleep Deprivation

The impact of inadequate sleep extends far beyond daytime fatigue. Chronic sleep deprivation is a major risk factor for numerous health issues, including:

• Cardiovascular Disease: Sleep deprivation increases blood pressure, heart rate, and inflammation, raising the risk of heart attack and stroke.
• Diabetes: Poor sleep disrupts glucose metabolism, increasing the risk of type 2 diabetes.
• Obesity: Lack of sleep affects hormones that regulate appetite, leading to increased cravings for unhealthy foods and weight gain.
• Mental Health Issues: Sleep deprivation exacerbates anxiety, depression, and irritability.
• Weakened Immune System: Sleep is crucial for immune function, and lack of sleep makes you more susceptible to illness.

What Can You Do? Prioritising Sleep for Better Health

The good news is that there are steps you can take to improve your sleep. Here are some practical tips:

• Establish a Regular Sleep Schedule: Go to bed and wake up around the same time each day, even on weekends.
• Create a Relaxing Bedtime Routine: Wind down before bed with a warm bath, reading, or meditation.
• Optimize Your Sleep Environment: Make sure your bedroom is dark, quiet, and cool.
• Limit Screen Time Before Bed: Avoid using electronic devices for at least an hour before sleep.
• Watch Your Diet and Exercise: Avoid caffeine and alcohol before bed, and engage in regular physical activity (but not too close to bedtime).
• Seek Professional Help: If you're struggling with persistent sleep problems, consult a doctor or sleep specialist.
