A certain amount of stress is normal and can be beneficial, but excessive stress can have a negative effect on your sleep. The main reason for this is the release of cortisol, a stress hormone that keeps you alert and prevents you from sleeping.
Cortisol is a natural hormone that is released when you wake up and helps you to stay more alert. However, it becomes a nightmare when you try to sleep.
Your subconscious can be overwhelmed by racing, intrusive thoughts and unpleasant feelings. Stress and anxiety can manifest themselves in subtle ways and cause you to wake up frequently during the night.
An imbalance in your gastrointestinal microbiome can disrupt your sleep. This is usually related to an excess of cortisol, which can affect the good bacteria in your digestive system.
An unbalanced microbiome also has difficulty converting tryptophan (an amino acid) into serotonin (a neurotransmitter), which can affect your sleep.
If you are struggling with this, taking probiotics may be the answer to your problem. They can improve your gastrointestinal microbiome and therefore the quality of your sleep.
Your blood sugar level fluctuates slightly during the day and if it drops sharply before bedtime, it can affect your sleep.
Low blood sugar levels during sleep can be caused by a number of factors, including diet. When blood sugar levels are low, the adrenal glands release cortisol, which in turn can disrupt the quality of your sleep.
Maintaining a stable blood sugar level can be achieved through a balanced diet. A light snack before bedtime that contains protein and fats such as nuts can help you keep it stable.
Nicotine, in whatever form, can keep you awake at night because it has a stimulating effect. This is exactly what you don't need if you want to sleep like a rock.
A lot of people enjoy coffee and other caffeinated drinks such as tea. However, this is a stimulant that you should avoid. If you drink it, have your cup at least six hours before going to bed.
Perhaps your body needs a nutrient that it is currently lacking, such as vitamin D. This essential vitamin plays a crucial role in the production of melatonin, a sleep-regulating hormone.
While some foods contain vitamin D, the best source is still the sun. Sun exposure helps regulate your circadian rhythm. This means your eyes stay closed at night.
Magnesium is another nutrient that can help you get a good night's sleep. It is responsible for various bodily functions, such as boosting gamma-aminobutyric acid (GABA), a neurotransmitter that helps your body to relax.
A hormonal imbalance could be the reason why your sleep cycle is repeatedly interrupted. It is often difficult for menopausal women to get a good night's sleep.
Low progesterone levels, which typically occur during menstruation, can also have a negative effect on sleep quality.
If you suffer from sleep apnea, you stop breathing briefly during sleep, with pauses that can last up to 30 seconds. Sleep apnea can cause you to move around and wake up frequently during the night.
Sleep apnea not only disturbs sleep, but is also associated with other health conditions, such as cardiovascular problems, and causes terrible discomfort.
Do you get up at night to pee again and again? Then you may be dealing with nocturia. This condition can severely affect the quality of your sleep.
An overactive bladder triggered by low levels of the antidiuretic hormone vasopressin can be the cause of nocturia. This can happen as you get older.
There are other factors that cause you to pee frequently at night. You may be suffering from nocturnal hyperglycemia, which, unlike the diet-related reasons mentioned previously, can be linked to diabetes.
If you experience other symptoms in addition to the urge to pee, such as irritability and headaches, you should talk to your doctor. Restless leg syndrome can also be a sign of fluctuating blood sugar levels at night.
An imbalance in liver function can really affect your sleep. The liver is responsible for metabolizing melatonin, which is crucial for the sleep-wake cycle.
Pay a visit to your doctor if you have other symptoms such as itchy skin, loss of appetite or tenderness in the liver area. Liver conditions should not be ignored.
If your thyroid gland is overactive and produces a large amount of hormones, this is called hyperthyroidism. If you suffer from this, you may feel a little restless and irritable, and it is quite natural that you find it difficult to sleep.
But the opposite, hypothyroidism, can also disturb your sleep. An underactive thyroid can cause muscle and joint pain and make you more susceptible to anxiety.
The process that regulates our sleep–wake cycle can change. Jet lag, for example, can severely affect our sleep.
If you work shifts, it'll come as no surprise that your job is a big circadian rhythm disruptor.
