Irregular Sleep-Wake Rhythm Disorder

Irregular Sleep-Wake Rhythm Disorder (ISWRD)

Sleep disorders affect millions of people every year. According to the  National Institutes of Health, approximately 25% of adults experience some form of insomnia at least once per week.

Insomnia is defined as difficulty falling or staying asleep or waking too early.

ISWRD is a condition characterised by a disruption in the   circadian rhythms of sleep and wakefulness.

This disruption leads to alertness, cognition, mood, and behaviour problems. People who suffer from ISWRD often report feeling tired during the day, having trouble concentrating, and being irritable.

They may also have trouble sleeping at night, and they may be more likely to make poor decisions due to a lack of energy.

The exact cause of ISWRD is not known. However, it has been associated with certain medical conditions such as depression, bipolar disorder, anxiety, and  chronic pain.

 It can also occur after surgery when people recover from an illness or injury.

This blog post will discuss Irregular Sleep-Wake Rhythm Disorder and how it affects your life.

We will also provide you with tips on dealing with it effectively.

    What Is The Cause Of Sleep-Wake Irregularities?

    The primary cause of sleep-wake disorders is the absence of the circadian rhythm that is responsible for  regulating the time of sleep and wakefulness.

    People suffering from neurodegenerative disorders such as Alzheimer's disease have a greater chance of developing the sleep-wake rare syndrome.

    The incidence of sleep-wake cycles is higher as you advance. However, age is not a risk factor.

    Age-related changes in neurological, medical, and psychiatric disorders can contribute to the development of this disorder.

    A variety of factors not connected to  sleep-wake disorders could temporarily disrupt the sleep-wake cycle.

    They include shifts that are not regular (switching between changes during the day and at night) or frequent movement between various time zones.

    Do Irregular Sleep-Wake Disorders Require Medical Attention?

    The inability to sleep and wake up at different periods and even sleeping for short durations can be due to situations in life that aren't medical emergencies.

    Tips For Dealing With Irregular Sleep-Wake Rhythms

    Here are some general tips that may help you to combat Irregular Sleep-Wake Rhythms in the longer run:

    2.   Avoid caffeine. Caffeine stimulates the nervous system and makes it  harder to fall asleep.
    3.   Exercise regularly. Exercise helps reduce fatigue and improves concentration.
    4.   Eat regular meals. Eating small frequent meals keeps blood sugar levels stable.
    5.  Reduce stress. Stress increases cortisol secretion, which causes drowsiness.
    6.   Practice relaxation techniques. Relaxation exercises like meditation or yoga help calm the mind and relax muscles.
    7.   Try melatonin supplements. The body naturally produces melatonin during sleep. It has been shown to improve sleep quality.
    8.   Take magnesium supplements. Magnesium deficiency is associated with poor sleep quality.
    9.   Drink plenty of water. Water flushes toxins from the body and helps regulate sleep.
    10.               Use an  eye mask. Eye masks block light so that the brain perceives darkness as being more profound than it is. It allows the brain to enter into a more restful state.

    Medical Treatment

    Medications such as melatonin (available over-the-counter) and other agents that promote wakefulness (such as modafinil [Provigil(r)) and caffeine, as well as short-term sleep aids, can be used to modify and sustain the sleep-wake cycle to the  ideal routine.

    Tasimelteon (Hetlioz(r)) is approved for treating non-24-hour sleep-wake disorder.

    Once you have the desired pattern established, it is essential to adhere to this regular sleep-wake pattern.

    When To See A Doctor?
