Waking Up to Ageing: The Truth About Lighter Sleep

Imagine this: It’s 3 AM in the heart of Malta’s Three Cities. The usual hum of Valletta’s nightlife has died down, and the only sound is the gentle lapping of water against the ancient walls. Yet, you’re wide awake, your mind racing, your body restless. You’re not alone. Many of us, as we age, find ourselves waking up more frequently, our sleep growing lighter. But is this a normal part of ageing, or a sign that something’s amiss?

Ageing and Sleep: A Natural Process?

Dr. Joseph Casha, a respected geriatrician at Mater Dei Hospital, explains, “As we age, our sleep patterns naturally change. Our sleep becomes lighter, we wake up more frequently, and we often need less sleep overall.” This is due to various factors, including physical changes, hormonal shifts, and the brain’s natural ageing process.

For instance, the hormone melatonin, which regulates our sleep-wake cycle, decreases with age. Additionally, the brain’s ability to maintain deep sleep stages declines, leading to lighter sleep. “Think of it like a dimmer switch,” Dr. Casha says. “As we age, our brain’s ‘sleep switch’ becomes less intense, making our sleep lighter.”

When Lighter Sleep Isn’t Normal

While lighter sleep is a normal part of ageing, it’s not always harmless. Sometimes, it can be a sign of an underlying health issue. Insomnia, sleep apnea, restless leg syndrome, and even conditions like dementia and Parkinson’s disease can disrupt sleep. Dr. Casha warns, “If you’re waking up frequently, feeling tired during the day, or notice other changes in your sleep pattern, it’s worth talking to your doctor.”

Local resident Maria, a 65-year-old retired teacher from Msida, shares her experience. “I used to sleep like a log, but now I wake up every few hours. I’m tired all day, and it’s affecting my mood. I didn’t know it could be a sign of something serious.” After consulting her doctor, Maria was diagnosed with sleep apnea and now uses a CPAP machine, improving her sleep significantly.

Tips for Better Sleep as We Age

So, what can we do to improve our sleep as we age? Dr. Casha suggests a few strategies:

• Establish a consistent sleep schedule, even on weekends.
• Create a relaxing bedtime routine. This could be reading, gentle stretching, or writing in a journal.
• Keep your sleep environment cool, dark, and quiet. Consider using earplugs, an eye mask, or a white noise machine.
• Limit caffeine and alcohol close to bedtime. Both can disrupt sleep, especially as we age.
• Exercise regularly, but avoid intense workouts close to bedtime.

Dr. Casha also recommends staying mentally active. “Engaging in puzzles, learning new skills, or socializing can help improve sleep quality,” he says.

Remember, while lighter sleep is a normal part of ageing, it’s not something we have to endure without recourse. By understanding our sleep patterns and taking steps to improve them, we can wake up to ageing with renewed energy and vitality.

As Maria puts it, “I thought I just had to live with my sleep problems, but now I feel like a new person. It’s never too late to prioritize our sleep and our health.”
