Introduction
The sleep – wakefulness cycle is genetically determined rather than learned and is established sometime after birth.Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, relatively inhibited sensory activity and [inhibition of nearly all voluntary muscle during REM sleep] reduced interactions with surroundings.
Sleep can be regarded as a physiological reversible reduction of conscious awareness. Nearly one third of human life is spent in sleep. Disorders of sleep can affect activities of daily living (ADL) of an individual.
Definition
It is an easily reversible state of relative unresponsiveness and serenity which occurs more or less regularly and repetitively each day.
The EEG recordings show typical features of sleep which is broadly divided into two broadly different phases:
1. D-sleep (desynchronised or dreaming sleep), also called as REM- sleep (rapid eye movement sleep),active sleep, or paradoxical sleep.
2. S-sleep (synchronised sleep), also called as NREM-sleep (non-REM sleep), quiet sleep, or orthodox sleep. S-sleep or NREM-sleep is further divided into four stages, ranging from stages 1 to 4. As the person falls asleep, the person fifi rst passes through these stages of NREM-sleep.
Stages of sleep
The EEG recording during the waking state shows alpha waves of 8-12 cycles/sec. frequency. The onset of sleep is characterised by a disappearance of the alpha-activity.
Stage 1, NREM-sleep is the first and the ligh test stage of sleep characterised by an absence of alphawaves, and low voltage, predominantly theta activity.
Stage 2, NREM-sleep follows the stage 1 within a few minutes and is characterised by two typical EEG changes:
i. Sleep spindles: Regular spindle shaped waves of 13-15 cycles/sec. frequency, lasting 0.5-2.0
seconds, with a charac teristic waxing and waning amplitude.
ii. K-complexes: High voltage spikes present intermittently.
Stage 3, NREM-sleep shows appearance of high voltage, 75 μV, δ-waves of 0.5-3.0 cycles/sec.
Stage 4, NREM-sleep shows predominant δ-activity in EEG. NREM-sleep is followed by REM-sleep, which is a light phase of sleep. The EEG is characterised by a return of α-waves (α-wave sleep); other changes are similar to stage 1 NREM-sleep. One of the most characteristic features of the REM-sleep is presence of REM or rapid (conjugate) eye move ments. The other features include generalised mus cular atony, penile erection, autonomic hyperactivity (increase in pulse rate, respiratory rate and blood pressure), and movements of small muscle groups, occurring intermittently. Although it is a light stage of sleep, arousal is diffificult. These stages occur regularly throughout the whole duration of sleep. The first REM period occurs typically after 90 minutes of the onset of sleep, although it can start as early as 7 minutes after going off to sleep, e.g. in narcolepsy, in major depression, and after sleep deprivation.
How to Sleep Better 101 - Drew University - 9.8.19Summit Health
Thank you to Drew University’s Health Services Department for hosting Summit Medical Group Sleep experts, Vicky Seelall, MD, FCCP, and Kerry Kelley, RN, RRT, RPSGT, for a lecture on How to Sleep Better 101. Studies have shown that seven hours of sleep is crucial for better academic performance and maintaining a higher GPA. A better night sleep in also key for improving memory retention. One way to ensure you get that beneficial shut eye, is to reduce screen time at least two hours before bed.
It focuses on sleep medicine - sleep disorders, sleep stages, DSM classification, types, classifications, and pharmacological and non pharmacological management.

2024.06.01 Introducing a competency framework for languag learning materials ...Sandy Millin
http://sandymillin.wordpress.com/iateflwebinar2024
Published classroom materials form the basis of syllabuses, drive teacher professional development, and have a potentially huge influence on learners, teachers and education systems. All teachers also create their own materials, whether a few sentences on a blackboard, a highly-structured fully-realised online course, or anything in between. Despite this, the knowledge and skills needed to create effective language learning materials are rarely part of teacher training, and are mostly learnt by trial and error.
Knowledge and skills frameworks, generally called competency frameworks, for ELT teachers, trainers and managers have existed for a few years now. However, until I created one for my MA dissertation, there wasn’t one drawing together what we need to know and do to be able to effectively produce language learning materials.
This webinar will introduce you to my framework, highlighting the key competencies I identified from my research. It will also show how anybody involved in language teaching (any language, not just English!), teacher training, managing schools or developing language learning materials can benefit from using the framework.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.

• It is a physical or mental activity that you
do to stay healthy or to become strong.
(WHO, 2019).
• This is the performance of physical
exertion for improvement of health or
correction of physical deformity.
7
8. Definitions cont’
• Rest
• Refers to a state of relaxation and
calmness, both mental and physical.
• Activity during rest periods can range
from lying down to reading a book to
taking a quiet walk. (D’Arcy, 2008).
8
9. Definitions cont’
• Sleep
• Refers to a state of altered consciousness
during which an individual experiences
minimal physical activity and a general
slowing of the body’s physiological
processes.
9
10. Types of Exercises
• Passive Exercises: This is the motion
imparted to a segment of the body by
another individual, or a machine or other
outside forces.
• Active Exercises: This is the type of
exercises a patient can do himself or herself.
• This is the motion imparted to a part of the
body by voluntary contraction and relaxation
of its controlling muscles.
10
11. Importance of Exercises
• Promotes and develops good muscle tone.
• Stimulates circulation of blood.
• Prevents complications like deep vein
thrombosis.
• Prevents disability especially in burns.
• For better body alignment.
• Prevents constipation by improving and
maintaining the tone of the muscles used for
defecating.
11
12. Importance of Exercises cont.
• It promotes the flow of urine and emptying of
the bladder.
• Aids in the prevention of bed sores
• Prevents postural deformation which may occur
due to prolonged joint immobility.
• Stimulates the nervous system resulting in
improved condition and status of the patient.
• It helps to prevent cardiovascular
complications.
• It meets all human basic needs for movement
12
13. Importance of Rest and Sleep
• It is essential for the worn out body tissues
from activities to restore themselves.
• Rest facilitates resting of body organs.
• Sleep reduces stress, anxiety and tension.
• Helps the person to regain energy for
concentration, coping and maintaining
interest in daily activities.
13
14. Physiology of Sleep
• Sleep is a cyclic physiological process that
alternates with longer periods of wakefulness.
• The sleep-wake cycle influences and regulates
physiological function and behavioural
responses.
• Current theories indicates sleep is thought to
be an active inhibitory process.
14
15. Physiology of Sleep cont..
• Control and regulation of sleep may
depend on the interrelationship between
two cerebral mechanisms that
intermittently activates and suppress the
brain’s higher centers to control sleep
and wakefulness.
15
16. Physiology of Sleep cont..
• One mechanism causes wakefulness
whereas the other causes sleep. (Cortisol
and melatonin).
• The Ascending reticular Activating System
(RAS) located in the upper brain is believed
to contain special cells that maintain
alertness and wakefulness.
• The RAS receives visual, auditory, pain, and
tactile Sensory stimuli.
16
17. Physiology of Sleep Cont…
• Activity from the central cortex (e.g.
emotions or thoughts process) also
stimulates the RAS.
• Wakefulness results from the neurones in
the RAS that releases catecholamine such
as norepinephrine.
• Sleep may be produced by the release of
serotonin from specialised cells in the raphe
sleep system of the pons and medulla.
17
18. Physiology of Sleep Cont…
• Whether a person remains awake or falls
asleep depends on a balance of impulses
received from higher centres (thoughts),
peripheral sensory receptors (sound or light
stimuli) and the limbic system (emotions).
• As people try to fall asleep, they close their
eyes and assume relaxed positions. Stimuli to
the RAS decline.
• If the room is dark and quiet activation of the
RAS further declines. At some points the pons
and the medulla takes over causing sleep. 18
20. Stages of Sleep
• Electroencephalograph (EEG) patterns, eye
movements, and muscle activity are used to
identify stages of sleep. The stages of sleep
are classified in two categories: non–rapid
eye movement (NREM) and rapid eye
movement (REM) sleep.
• Stage 1. Is very light sleep. The person
feels drowsy and relaxed. The sleeper can be
readily awakened. This stage lasts for few
minutes. 20
21. Stages of Sleep cont..
• Stage 2. Light sleep during which the
body processes continue to slow down.
• The eyes are generally still, the heart
and respiratory rates decrease slightly,
and the body temperature falls.
• This stage lasts about 10 – 15 minutes.
21
22. Stages of Sleep cont..
• Stage 3. Occurs when the respiratory
and the heart rates and other body
processes slow down further because of
domination of the parasympathetic
nervous system.
• The sleeper becomes more difficult to
arouse.
22
23. Stages of Sleep cont..
• Stage 4. Signals deep, deep called
delta. The sleeper’s heart and respiratory
rates are 20 – 30% below waking rates.
• sleeper is very relaxed, rarely moves, and
is difficult to arouse.
• During this stage the eyes usually roll
and some dreaming occur.
23
24. General Principles of Rest and
Sleep
• Procedures in the ward should be done at
once to avoid disturbance of the patient.
• Tension should be eased by adequate
explanation given to the patient before any
procedure is done.
• Noise should be avoided.
• Limit the number of Visitors
24
25. General Principles of Rest and
Sleep cont’
• Physical comfort should be provided to the
patient by ensuring the following:-
• Relive pain
• Empty the bladder before sleep
• Changing of positioning
• Provide dim lighting
• Proper ventilation on the ward.
• Provide adequate warmth.
• Maintain hygiene for instance brushing teeth
before bed time
25
26. Factors affecting Rest and
Sleep
• Illness: - increases the need for sleep, but
disease often disrupts normal sleep rhythms.
• Environmental factors: - can either enhance
or impair sleep.
• Lighting, temperature, odors, ventilation, and
noise level can all interrupt the sleep process
when they differ from the norms of the client’s
usual sleep environment.
• Emotional stress:- Anxiety often results in
difficulty falling asleep or staying asleep 26
27. Factors affecting Rest and
Sleep cont’
• Diet: - type of food consumed has an impact
on the quality and quantity of sleep. Foods
high in caffeine, such as coffee, cola, and
chocolate, serve as stimulants and often
disrupt the normal sleep cycle.
• A large, heavy, or spicy meal just before
bedtime may cause indigestion, which will
likely interfere with sleep. Conversely, going
to bed when hungry can also result in sleep
problems 27
28. Factors affecting Rest and
Sleep cont’
• Lifestyle;- having a work schedule that
does not coincide with an individual’s
biological clock (e.g., working at times
other than the day shift).
• Individuals who frequently change work
shifts have a real challenge trying to
stabilize biological rhythms and rest.
28
29. Factors affecting Rest and
Sleep Cont…
• Drugs and Other Substances:-Alcohol and
nicotine use can impair sleep. Small amounts
of alcohol may help some people fall asleep;
however, in others alcohol may interfere with
REM sleep, causing very restless and non-
refreshing sleep.
• Nicotine, which is a stimulant, can also
impair the sleep cycle by stimulating the
body, resulting in difficulty falling and staying
asleep 29
30. Factors affecting Rest and
Sleep Cont…
• Many medications (both prescription and over
the counter) cause fatigue, sleepiness,
restlessness, agitation, or insomnia, thus
affecting the quality and quantity of rest and
sleep.
• Cultural: - some patient fears the hospital
environment as stranger (procedures, light,
and uniform for nurse). Cultural or ethnic
customs may have an impact on a client’s
ability to achieve rest and sleep.
30
31. Factors affecting Rest and
Sleep Cont…
• Degree of Comfort- Comfort is a highly
subjective experience.
• The nurse must assess the degree to which
the client’s physical and psychological needs
have been met.
• Whenever basic needs are unmet, the
person experiences discomfort, which leads
to physiological tension, resultant anxiety,
and potential impairments in sleep and rest.
31
32. Recommended hours of
sleeping
• Neonate (birth to 1 month) sleeps in 3 to 4
hour intervals for a total of about 16 to 20
hours a day.
• Infant (1month to 2 years) averages
about 12 to 16 hours of sleep a day with
naps 2 to 3 times during the day.
• Toddlerhood (2 to 3 years) average sleep
is 12 to 14 hours at night with 1 to 2 naps
during the day.
32
33. Recommended hours of
sleeping cont’
• Pre-school child (4 to 6 years) sleeps approximately
10 to 12 hours a day. Daytime napping decreases or
ceases, unless cultural norms dictate otherwise.
• School-age child (7-8years) sleep 10 to 12 hours of
sleep daily
• Adolescents sleep about 8 to 10 hours a day and
often decide their bedtime routines and hours.
• Middle-age adult sleeps about 6 to 8 hours a day
• Older adult - sleeps 5 to 7 hours a day.
33
34. Measures to Promote Rest
and Sleep
• Eliminate noise
• Patients should not be hungry, provide a snack
where possible, for instance a glass of milk.
• Give water to patients who may need it at night
for instance full the jugs and put them within
reach of patient.
• Prepare the patient by giving a bedpan or urinal.
• Blankets should be adequate for warmth because,
a well-made and clean bed promotes sleep.
34
35. Measures to Promote Rest
and Sleep cont’
• Prescribed medications should be given
early to help patients sleep for instance
analgesics for pain.
• Tell the patient to be free to ask for help.
• Give the patient a soothing bath.
• Reading or watching a movies.
35
36. Rehabilitative measures
• sleep can be enhanced by the following
measures;
• Encourage client to establish a bed time routine
and a regular sleep pattern to help induce
sleep.
• Clients should limit intake of caffeine, nicotine
and alcohol before bed time because they are
stimulants and may cause difficulties in falling
asleep, and alcohol fragment sleep.
36
37. Rehabilitative measures cont’
• Clients should avoid stressful concerns before bed
time because this may stimulate them and
prevent sleep.
• They should adjust the environment, that is
controlling noise, temperature and lighting in the
bed room to provide a conducive environment to
sleep
• Clients should avoid exercises 2-3hours before
bed time because they stimulates the client and
prevent sleep.
37
38. Summary
• We have come to the end of our Lecture/
Discussion. We have defined exercise as a
physical or mental activity that you do to stay
healthy or to become strong; Rest as a state
of relaxation and calmness, both mental and
physical.
• Activity during rest periods can range from
lying down to reading a book to taking a quiet
walk and Sleep as a state of altered
consciousness during which an individual
experiences minimal physical activity and a
general slowing of the body’s physiological
38
39. Summary cont..
• We have also discussed about the importance
of the rest and sleep which facilitates resting
of body organs. The principles of sleep such
as never go to sleep with an empty stomach,
full bladder or after a heavy fatty meal.
• Sleep pattern is regulated by the
diencephalon structures and the reticular
activating system and we further discussed on
the four stages of sleep, factors that affect
sleep such as emotional stress. 39
