How to Support Your Body Through the Night.

In my last blog post, I looked at how sleep is the foundation for your physical progress. But for many women over 40, your sleep system feels like it’s lost its rhythm. Between shifting hormones and a demanding life, your body can become so much more sensitive to things that didn't used to bother it. If you’re doing your best to rest but finding yourself wide awake in the middle of the night, it’s usually because of a biological glitch. Here is how to navigate some of the most common middle of the night hurdles.

Waking up suddenly around 3:00 AM, feeling very alert or even a bit anxious, this could be caused by your energy levels. When your blood sugar drops too low while you sleep, your brain perceives it as an emergency. To fix it, your body releases cortisol a wake-up hormone to tell your liver to release more fuel. You aren't necessarily waking up because you're stressed, you could be waking up because your brain decided it needs to get more energy [1].

Try a small energy stabilising snack about 30 to 60 minutes before bed. Focus on a combination of fibre and healthy fats, like a few walnuts or a small spoonful of unsweetened nut butter. This provides a slow-burning fuel source that helps keep your levels steady until morning.

As estrogen levels fluctuate, the part of your brain that controls temperature becomes much more sensitive. This narrows your comfort zone, meaning a tiny rise in room temperature can trigger a full-scale hot flush or night sweat that wakes you up [2].

If this is a problem for you, try using a technique called Thermal Dumping. Your body actually needs its internal temperature to drop by about 1°C to fall into a deep sleep. Taking a warm (not hot) bath or shower about 90 minutes before bed brings blood to the surface of your skin. When you step out, that heat is removed, helping your core temperature to drop.

Progesterone plays a key role in helping your brain feel calm and ready for sleep. As levels fluctuate in our 40s, that sense of quiet can be hard to find, often leading to that tired but wired feeling where your body is exhausted, but your mind won't stop racing [3].

Since your body isn't providing that calm, you can create a manual reset to signal that the day is over.

Try using the Physiological Sigh. This is a specific breathing pattern, take a deep breath in through your nose, follow it with a second sip of air to fully expand the lungs, and then a long, slow exhale through your mouth. Doing this 3 times helps lower your heart rate and can signal your nervous system to transition into a parasympathetic (rest) state.

Once you are in bed, try the 3-2-1 Orienting method. Instead of engaging with your thoughts, engage with your environment.

Identify 3 things you can hear.

Identify 2 things you can feel.

Identify 1 thing you can smell.

Many women wake up thinking they have to pee, but it’s often much more complex. Lower estrogen can make the lining of the bladder more sensitive. Often, you might wake up for another reason like a temperature spike but the first sensation your brain notices is a slightly full bladder, making you think that was the reason you woke up [4].

 Aim to drink about 70% of your daily water before 4:00 PM. This keeps you hydrated for your health but gives your kidneys a chance to slow down before you go to bed.

If you do wake up, try "belly breathing" (diaphragmatic breathing) for a minute before getting out of bed. This can calm the pelvic floor and often settles that false alarm feeling from the bladder. But if you do need to pee, it’s probably best to get up…

Your body has a natural window for sleep, usually between 10:00 PM and 11:00 PM. If you push past that window, your body assumes you need to stay awake for a reason and gives you a second wind of cortisol. Be mindful of evening light. Between 8:30 PM and bedtime, your eyes are very sensitive to the blue light from phones and bright overhead bulbs, which tells your brain the sun is still up. Switching to soft, amber-toned lamps in the evening helps your natural sleep hormones rise [5].

Don't try to change everything at once. Pick the one thing that disrupts your night the most:

If you wake up hungry or alert: Try the pre-bed snack.

If you wake up hot: Try the warm shower 90 minutes before bed.

If you can't quiet your mind: Try 3-2-1 Orienting method or the Physiological Sigh.

By giving your body these small, biological nudges, you can help it find its way back to the restorative sleep you’ve been trying to get.
