While insomnia is typically thought of as not being able to fall asleep or stay asleep, there is a lesser-known sleep disorder called late insomnia that can be just as frustrating.
“Late insomnia, or early morning awakening, is when you wake up much earlier than you want to and can’t fall back asleep, even though you’re still tired,” Dr. Angela Holliday-Bell, a physician and sleep specialist, told HuffPost.
While anyone can experience late insomnia, it becomes more likely with age, according to the journal ”Sleep Medicine Clinics.” Sleep doctors say there are a few reasons why late insomnia is more common with age, but the good news is that there is a lot you can do about it.
Why Late Insomnia Is More Common With Age
Late insomnia isn’t an official medical diagnosis, but Dr. Meredith Broderick, a sleep neurologist and Ozlo medical advisory board member, explained that it describes waking up spontaneously between 1.5 and 2 hours earlier than you plan to. She shared that this isn’t considered a problem if it happens occasionally, but if it occurs at least three times a week for at least three months, it’s considered late insomnia.
There are four major reasons why late insomnia happens and why older adults are most prone to experience it, according to sleep doctors.
1. Circadian rhythm naturally changes as we age
Dr. William Lu, a sleep doctor and the medical director at Dreem Health, told HuffPost that circadian rhythm changes as we age, which can contribute to late insomnia. “The body’s internal clock shifts with age, causing people to feel sleepy and wake earlier than they used to,” he said. Lu explained that older adults tend to spend less time in deep sleep and more time in lighter stages, making them more prone to waking up early.
“In addition, melatonin production declines, which can reduce sleep quality,” Lu added. As if that wasn’t enough to cause sleeping problems, Lu shared that sleep apnea is also more common with age, which can also contribute to late insomnia.
2. Hormonal shifts
For women, perimenopause and menopause can contribute to sleep disorders, including late insomnia. “In perimenopause and menopause, hormonal shifts — especially declining oestrogen and progesterone — affect the brain’s sleep centre and circadian rhythm. These changes are not just due to hot flashes. These changes can trigger night wakings, especially when combined with elevated cortisol and a dysregulated circadian rhythm, said Dr. Romie Mushtaq, a neurologist, integrative medicine doctor and author of “The Busy Brain Cure.”
Holliday-Bell added to this, saying that lower oestrogen can also lead to lighter, more fragmented sleep. On top of that, she said that many menopausal women experience night sweats and hot flashes that wake them in the early morning hours and make it hard to fall back asleep.
3. Depression and anxiety
All of the sleep experts told HuffPost that late insomnia is a hallmark symptom of depression, which scientific research backs up. Lu explained that depression can lead to waking up in the early morning because it changes the circadian rhythm and leads to elevated morning cortisol levels.
“Anxiety and stress also contribute by keeping the brain in a hyper-alert state, making it difficult to fall back asleep,” he added.
4. Alcohol
Mushtaq told HuffPost that the most common reason for late insomnia that she sees (in adults of all ages) is alcohol use. While alcohol may help someone initially fall asleep, a wealth of scientific research shows that it’s associated with sleep disturbances. These sleep interruptions often happen during REM sleep, which occurs in the second half of the night, including the early morning hours.
How To Stop Experiencing Late Insomnia
The first step to overcoming late insomnia is identifying the reason why you are experiencing it, according to sleep experts. Often, this makes the next step pretty logical. For example, if you tend to unwind in the evening with an alcoholic drink, spend the next few weeks going without it and seeing if it makes a difference. If hot flashes are waking you up and you can’t fall back asleep, outfitting your bed with cooling sheets and lowering the temperature are good first steps to take.
Don’t know what the root cause is? Then it’s time to do some detective work. “Start by looking at your habits. Keep a consistent sleep and wake time, create a calming bedtime routine and avoid alcohol, caffeine and bright screens late in the day,” Holliday-Bell recommended. In other words, take a close look at your lifestyle and change anything that isn’t a good sleep hygiene habit.
If you think your mental health is contributing to your late insomnia, all of the sleep experts recommend seeing a therapist who can help you find healthy ways to manage your depression, anxiety or stress so that it doesn’t interfere with your sleep. They all say that asking your primary care provider to refer you to a sleep specialist can be beneficial, too. A sleep specialist can serve as your co-detective, helping you pinpoint the reason why you’re waking up so early and then troubleshooting accordingly.
Though late insomnia isn’t uncommon among older adults, Mushtaq emphasized that it isn’t normal. “Late insomnia isn’t just about aging; it’s often a signal that your stress response is out of sync. Healing starts with calming the brain at night and supporting the body’s natural rhythms. With the right tools, including targeted supplements, we can restore both sleep and sanity,” she said.
If you’re experiencing late insomnia, consider what your body is trying to communicate to you. It may be a self-care alarm bell going off, signalling that one part of your life needs a little extra attention. Once you take action, you’ll sleep more deeply — and longer.
