Imbalances in liver function can have a big impact on your sleep. Your liver is responsible for metabolizing melatonin, which is key in the sleep-wake cycle.
Do you get up numerous times during the night to urinate? You might suffer from nocturia. Constant night trips to the bathroom can really affect the quality of your sleep.
This condition causes you to stop breathing briefly during sleep, with pauses that can take up to 30 seconds. Sleep apnea can make you move around a lot during the night and wake you up.
A drop in progesterone levels, which is experienced during menstruation, can also affect sleep negatively.
If this urge to pee is accompanied by other symptoms, including irritability and headaches, it’s best to talk to your doctor about it. Restless leg syndrome might also be a sign of fluctuating blood sugar at night.
Nocturia may be caused by a number of factors, namely an overactive bladder triggered by low levels of the hormone vasopressin, which is an antidiuretic. This can happen as we age.
Sleep apnea not only is annoying and disturbs your sleep, but it’s also linked to a number of conditions, including cardiovascular problems.
There are other reasons that can urge you to go to the bathroom multiple times during the night. You may suffer from nocturnal hyperglycemia, which, unlike the dietary reasons mentioned previously, might be linked to diabetes.
Some foods do contain vitamin D, but the best source is the sun. Sun exposure can help regulate your circadian rhythm, and prevent you from waking up in the middle of the night as often.
A balanced diet can go a long way when it comes to keeping blood sugar levels stable. A light pre-bed snack containing protein and fats (e.g. nuts) might also help keep blood sugar levels stable for longer.
If this is your case, taking probiotics may help improve gastrointestinal microbiome, and therefore the quality of your sleep.
Low glucose levels during sleep may be caused by a number of factors, including diet. Low blood sugar will prompt your adrenal glands to release cortisol and consequently disturb the quality of your sleep.
Magnesium is another nutrient that can help you have a restful sleep. Magnesium is responsible for a number of processes, including increasing the levels of the neurotransmitter gamma-aminobutyric acid (GABA), which helps your body relax.
Your blood sugar levels fluctuate slightly throughout the day, but if they drop considerably when you go to bed, it can have an impact on your sleep.
Racing, intrusive thoughts, and uneasy feelings might take over your subconscious. Stress and anxiety can manifest in a more subtle way, but can indeed be the reason why you keep waking up in the middle of the night.
An imbalance in your gastrointestinal microbiome can actually disturb your sleep. This is usually tied up with an excess of cortisol, which may affect your gut’s good bacteria.
Cortisol is naturally released when you wake up, and indeed helps you become more alert. Though it’s not helpful when it’s time to hit the sack!
Your body might need a nutrient that it is not getting. An example would be vitamin D. This vitamin is critical in the production of the sleep-regulating hormone melatonin.
The process that regulates our sleep–wake cycle can change. Jet lag, for instance, can have a huge impact on our sleep.
A hormonal imbalance might keep waking you up in the middle of the night. Menopausal women, for instance, may experience hormonal fluctuations that affect sleep.
See your doctor if you have other symptoms such as itchy skin, loss of appetite, or tenderness around the liver area. Liver conditions should not be ignored.
When your thyroid is overactive and produces a great quantity of hormones, also known as hyperthyroidism, you may feel a bit restless and irritable, which can keep you up at night.
A bit of stress is normal and even beneficial, but too much of it can have an impact on your sleep. This is mostly due to the release of the stress hormone cortisol, which leaves you in a state of alertness.
