Waking Up to Ageing: The Truth About Lighter Sleep

Imagine this: It’s 3 AM, and you’re wide awake, staring at the ceiling of your apartment in Sliema. You’ve been sleeping lighter, waking up more frequently, and feeling tired throughout the day. You’re not alone. Many of us in Malta are experiencing this as we age. But is lighter sleep a normal part of ageing, or is something else going on?

Understanding Sleep Architecture

To understand why sleep might change with age, let’s first look at what happens when we sleep. Sleep is not a uniform state but a dynamic process with different stages. There are two main types: rapid eye movement (REM) and non-rapid eye movement (NREM) sleep. NREM sleep is further divided into three stages, with stage 3 being the deepest.

As we age, our sleep architecture changes. The amount of deep sleep we get decreases, while light sleep and wakefulness increase. This is why older adults might feel like they’re sleeping lighter or waking up more often.

Malta’s Ageing Population: A Closer Look

Malta’s population is ageing rapidly. According to Eurostat, by 2070, nearly one-third of Malta’s population will be aged 65 and over. With this demographic shift comes a rise in age-related health issues, including sleep problems.

Dr. Joseph Cuschieri, a local geriatrician, explains, “As we age, our bodies change, and so does our sleep. It’s normal to have lighter sleep, but it’s also important to ensure that it doesn’t negatively impact our quality of life.”

When Lighter Sleep Isn’t Normal

While lighter sleep can be a normal part of ageing, it’s not always the case. Several factors can disrupt sleep as we get older, including:

• Health conditions like arthritis, heart disease, and respiratory issues, which are more common in older adults.
• Medications that interfere with sleep.
• Sleep disorders like insomnia, sleep apnea, and restless leg syndrome.
• Lifestyle factors like poor sleep habits, irregular schedules, and stress.

If lighter sleep is causing daytime sleepiness, poor concentration, or other issues, it’s important to talk to a healthcare provider. They can help determine if there’s an underlying issue that needs to be addressed.

Tips for Better Sleep in Malta

Whether you’re in your 50s or 80s, there are steps you can take to improve your sleep:

• Establish a consistent sleep schedule. Go to bed and wake up at the same time every day, even on weekends.
• Create a relaxing bedtime routine. This could include reading, gentle stretching, or listening to calming music.
• Optimize your sleep environment. Keep your bedroom cool, dark, and quiet. Consider using earplugs or an eye mask if needed.
• Limit exposure to screens before bedtime. The blue light emitted by phones, tablets, computers, and TVs can interfere with your body’s production of melatonin, a hormone that regulates sleep.
• Exercise regularly. Regular physical activity can help you fall asleep faster and enjoy deeper sleep.

If you’re struggling with sleep, don’t suffer in silence. Talk to your doctor or a sleep specialist. They can provide personalized advice and treatment options.

Remember, while lighter sleep can be a normal part of ageing, it doesn’t have to be. With the right strategies and perhaps a little help from healthcare professionals, we can all enjoy better sleep, no matter our age.

As Dr. Cuschieri puts it, “Ageing is a part of life, but it doesn’t have to mean sacrificing a good night’s sleep.”
