  Psychiatric and medical
conditions, unhealthy sleep habits, specific substances, and/or certain
biological factors can cause insomnia. Your brain has a sleep cycle and a wake
cycle. When one is turned on the other is turned off, insomnia can be a problem
with either part of this cycle: too much wake drive or too little sleep drive. Recently,
researchers have begun to think about insomnia as a problem of your brain being
unable to stop being awake. Followings are the possible causes for insomnia.

There are many medical conditions (some mild and others more
serious) that can lead to insomnia. In some cases, a medical condition itself
causes insomnia, while in other cases, symptoms of the condition cause
discomfort that can make it difficult for a person to sleep.

Examples of medical conditions that can cause insomnia are:

problems such as reflux
problems such as hyperthyroidism
conditions such as Parkinson’s disease
Chronic pain
Low back pain

  Medications such as those
taken for the common cold and nasal allergies, high blood pressure, heart
disease, thyroid disease, birth control, asthma, and depression can also cause

   In addition, insomnia may
be a symptom of underlying sleep disorders. For example, restless legs
syndrome. A neurological condition in which a person has
an uncomfortable sensation of needing to move his or her legs can lead to
insomnia. Patients with restless legs syndrome typically experience worse
symptoms in the later part of the day, during periods of inactivity, and in the
transition from wake to sleep, which means that falling asleep and staying
asleep can be difficult. An estimated 10 percent of the population has restless
legs syndrome.

  Sleep apnea is another sleep disorder linked to insomnia. With sleep apnea, a
person’s airway becomes partially or completely obstructed during sleep,
leading to pauses in breathing and a drop in oxygen levels. This causes a
person to wake up briefly but repeatedly throughout the night. People with
sleep apnea sometimes report experiencing insomnia.

   If someone has trouble
sleeping on a regular basis, it’s a good idea to review your health and think
about whether any underlying medical issues or sleep disorders could be
contributing to your sleep problems. In some cases, there are simple steps that
can be taken to improve sleep (such as avoiding bright lighting while winding
down and trying to limit possible distractions, such as a TV, computer, or
pets). While in other cases, it’s important to talk to your doctor to figure
out a course of action. You should not simply accept poor sleep as a way of
life-talk to your doctor or a sleep specialist for help.

Insomnia can be caused by psychiatric conditions such as depression. Psychological struggles can make it hard to sleep, insomnia
itself can bring on changes in mood, and shifts in hormones and physiology can
lead to both psychiatric issues and insomnia at the same time.

Sleep problems may represent a symptom of depression, and the risk
of severe insomnia is much higher in patients with major depressive disorders.
Studies show that insomnia can also trigger or worsen depression.

It’s important to know that symptoms of depression (such as low
energy, loss of interest or motivation, feelings of sadness or hopelessness)
and insomnia can be linked, and one can make the other worse. The good news is
that both are treatable regardless of which came first.

Most adults have had some trouble sleeping because they feel
worried or nervous, but for some it’s a pattern that interferes with sleep on a
regular basis. Anxiety symptoms that can lead to insomnia include:

caught up in thoughts about past events
worrying about future events
overwhelmed by responsibilities
A general
feeling of being revved up or over stimulated

It is not hard to see why these symptoms of general anxiety can
make it difficult to sleep. Anxiety may be associated with onset insomnia
(trouble falling asleep), or maintenance insomnia (waking up during the night
and not being able to return to sleep). In either case, the quiet and
inactivity of night often brings on stressful thoughts or even fears that keep
a person awake.

When this happens for many nights (or many months), the victims
might start to feel anxiousness, dread, or panic at just the prospect of not
sleeping. This is how anxiety and insomnia can feed each other and become a
cycle that should be interrupted through treatment. There are cognitive and mind-body techniques that help people with anxiety settle into sleep, and overall healthy sleep practices that can improve sleep for many people with anxiety and

2.5 Consequences of Insomnia


to its chronicity, insomnia is linked with substantial impairments in an
individual’s quality of life. In several studies, insomniacs reported decreased
quality of life on virtually all dimensions of the 36-item Short Form Health
Survey of the Medical Outcomes Study (SF-36), which assesses 8 domains: (1)
physical functioning; (2) role limitation due to physical health problems (role
physical); (3) bodily pain; (4) general health perceptions; (5) vitality; (6)
social functioning; (7) role limitations due to emotional health problems (role
emotional); and (8) mental health. (McHorney, Ware, & Raczek 1993; Ware, Lu, & Sherbourne 1994).


Balter, Uhlenhuth, (1992)
found that research has shown that among
the daytime consequences of insomnia, the increased occurrence of accidents
poses the greatest health risk. Insomniacs are 2.5 to 4.5 times more likely
than controls to have an accident. Kuppermann et al. (1995) found that individuals reporting a current sleep problem
were more likely than good sleepers to have decreased job performance and to
have been absent from work in the last month due to health problems.


Benca (2001)
identified that population–and clinic-based
studies have demonstrated a high rate of psychiatric comorbidities in patients
with chronic insomnia. In fact, insomnia is more frequently associated with psychiatric
disorders than any other medical illness. Additionally, depression and anxiety
are the most common comorbid psychiatric disorders in insomniacs. It has
traditionally been assumed that insomnia is secondary to the psychiatric
disorder; however, given the chronicity of insomnia, it is possible that in
some, if not most, cases the insomnia precedes the psychiatric disorder. In
fact, it is possible that insomnia represents a significant risk for the
development of a subsequent psychiatric disorder (Ohayon & Roth, 2003)

2.7 Herbal textile technology
inspired by Ayurvastra
     Ayurvastra is a branch of ancient Indian
herbal medicinal repository, Ayurveda, the ancient Vedic health care system
predating more than 5500 years, prescribes the use of Ayurvastra cloth to
cure a number of diseases like diabetes, skin infections, psoriasis, eczema,
hyper tension, asthma, arthritis, high blood pressure, rheumatism, arthritis
and cardiac problems. It is an ancient technique prevalent before textile
industrialization to dye cloth with herbal dyes, which then acts as a barrier
to the attack of various microorganisms. (Minocheherhomji & soanki, 2015)
    Jain (2010) states that such a fabric is
free from all synthetic toxic chemical substances, and is also fully
eco-friendly and biodegradable. The colors used are obtained from medicinal
plants only leaving no scope for the incorporation of synthetic dyes.
Ayurvastra helps the skin which being the outer covering of the body in its
function to prevent the entry of all foreign toxic substances, which are
lethal to the human body. The herbs incorporated in the fabric release their
medicinal properties onto and into the body thus providing medicinal immunity
against different harmful toxins.
    Ayurvastra clothing is made from organic
cellulosic fabric that has been previously treated with Ayurvedic oils and
herbs, which accelerate health and cure various diseases depending on the
blended oils and herbs. These fabrics also have anti-inflammatory properties and
These benefits of Ayurvastra clothing have been due to it helping the human
body in maintaining the balance between various bodily processes.
   The minute particles of active chemicals
like fragrances, skin care products, and medicinal items that are embedded in
the capsules are released on the account of body heat when the cloth comes
into the contact of the body. The skin leading to quick beneficial effects

Absorbs these products, as
the toxins in the body are either removed or neutralized. All the ingredients
of Ayurvastra are devoid of any synthetic toxic chemicals and are biodegradable.
it protects environment from pollution and damage.

     The dyeing procedure attempts
to keep medicinal properties intact in the textiles. Dye fixation is
accomplished using natural and harmless products having good medicinal
properties. The process is done in systematic steps to standardize the quality
and quantity of colors, thus achieving better consistency in longer running
output from one end to the other. Innovations in the process has made it
possible to dye all natural fibers such as cotton, jute, linen and silk in both
woven and knitted fabrics. There are two processes for making herbal textile. One
is, the yarn is treated before weaving, or another is, the fabric is dyed after
weaving. Herbal dyes are also directly applied onto textile fibers before
weaving and the time duration of the manufacture of herbal textile may be from
three to seven days depending upon the applications, which the textile is
expected to use.
