The document discusses various topics related to sleep including sleep cycles, sleep stages, sleep needs, sleep disorders, and dreams. The sleep cycle is regulated by the circadian rhythm and follows a roughly 25 hour pattern. There are 5 stages of sleep including light, deep, and REM sleep. Common sleep disorders include insomnia, sleep apnea, narcolepsy, and sleepwalking. Dreams occur during REM sleep and theories suggest dreams help with memory and process emotions.

Sleep: we all do it, and yet somehow it's hard (as most of us can attest every morning). It's also really relevant: as thinkers, creators, and problem solvers, anything that makes our brains less effective matters. Missed sleep makes a difference -- even two fewer hours a night quickly produce measurable cognitive impairment. Things get more interesting when we look at why it's so hard: our sleep cycles are determined by our internal clocks, which often put us in conflict with society's timetables, leaving many of us in a state of "social jet lag", as if we'd been traveling a timezone or more every day. That's not how any of us want to code (or live), I think, and by understanding how and why so many of us are constantly tired, we can start to make things better.
Dreams are generally referred to as images, stories, thoughts and emotions that occur while sleeping. Visual imagery is said to be the most common type of imagery. But all our senses can be constituted in our dreams. As people are different, the pattern of dreams also differs according to persons.

Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

2. Sleep Cycle
Part of the cycle of sleep and waking.
Circadian Rhythm: naturally
occurring 24-hr cycle.
Rest-activity of actually 25.1 hours.
Stay up longer, sleep in less.
Electrical activity in the brain
Higher-frequency when awake
Lower-frequency when relaxed
3. Sleep Stages
Stage 1: Drifting into sleep. “Trying”
to sleep.
Stage 2: Light Sleep. Lose
awareness.
Stage 3: Starting to fall into Deep
Sleep.
Stage 4: Deep Sleep.
REM Stage: Rapid Eye Movement.
Dreaming.
4. EEG Patterns
Electroencephalograph (Measures
electrical impulses produced by the
brain’s activity)
5. Sleep Needs
Varies depending on the age group.
Sleep helps with learning.
Sleep Deprivation.
6. Test Question
T/F: It is healthy for the average adult
to only get 5 hours of sleep a night.
9. 15% of adults complain of severe insomnia
15% report mild or occasional insomnia
Causes for insomnia include: anxiety, stress,
emotional difficulties
Some things to help with insomnia are better
sleep habits, using relaxation techniques
One solution to help insomnia is give up the
pursuit of sleep and find something to do
Sedatives such as sleeping pills can be helpful
but they can be addicting and people become
dependent on them
Sleeping pills can also interfere with your normal
sleep cycle and have side effects such as
grogginess and irritability
10. Sleep Apnea
Disorder in which the person stops
breathing for brief periods while asleep
11. Person with apnea usually snores, as apnea
involves an involuntary obstruction of the
breathing passage
When apnea occurs over 10 seconds at a time a
person may awaken and have sleep loss or
insomnia
Sleep apnea most often occurs in middle-aged
men who are overweight
Sleep apnea can go undiagnosed because it is
not easy for a sleeper to notice
To detect sleep apnea usually the sleeper’s bed
partner will get tired of the snoring and awaken
the sleeper
Some cures for sleep apnea are weight loss,
drugs, or surgery
12. Somnambulism
When a person arises and walks around
while sleeping, also known as
sleepwalking
13. Sleepwalking is more common in children
around the ages of 11 or 12, with as many
as 25% experiencing at least one episode
Sleepwalking tends to happen early in the
night, usually in slow-wave sleep.
Sleepwalkers may awaken during their
walk or return to bed without waking, in
which case they won’t remember anything
in the morning
Sleepwalkers can hurt themselves by
tripping over furniture or falling down the
stairs
Contrary to popular belief it is safe to
14. Narcolepsy
Disorder in which sudden sleep
attacks occur in the middle of waking
activities
15. Narcolepsy involves the intrusion of a
dreaming state of sleep (REM) into
waking and it often accompanied by
excessive sleepiness and incontrollable
sleep attacks lasting from 30 seconds
to 30 minutes
Narcolepsy is a less common sleep
disorder
The disorder appears to have a genetic
basis, as it runs in families
Narcolepsy can be treated with
medication
16. Sleep Paralysis
The experience of waking up unable
to move or speak for a few minutes
17. This eerie feeling only lasts for a few
moments and may occur with an
experience of pressure on the chest
Is sometimes associated with
narcolepsy
18. Night Terrors
Abrupt awakenings with panic and
intense emotional arousal
19. Mostly occurs with boys ages 3 to 7
Night terrors usually doesn’t have dream
content the sleeper can report
Night terrors usually occur within the first
few hours of sleep, whereas nightmares
occur towards the end of the night or
early morning hours
Night terrors occur during non-REM sleep
and nightmares occur during the REM of
sleep
20. Test Question
What is the sleep disorder in which
sudden sleep attacks occur in the
middle of wakening activities?
22. The Mind
dreams are a result of activities
taking place in the brain.
Scientist have found that the brain
gives off electromagnetic waves
while you dream.
During the period while the
electromagnetic waves are fast your
eyes are moving rapidly
Sometimes while dreaming you
cannot move your body, this period is
called REM
23. Mind
Scientist believe that dreaming sleep
has a role in restoring the brain's
ability to handle such tasks as
focused attention, memory, and
learning. Also a person's hidden
feelings often surface in dreams
25. Tips to avoid nightmares
and to get a good nights
sleep:
Sleep schedule
Avoid caffeine
Exercise
Don’t lie awake in bed
Control temperature
26. what you can do?
Before you go to bed: write down the
date and what events happened that
day (journal)
If you wake up in the middle of the
night: try to recall if you had any
dreams and write them down
When you wake up in the morning:
write down how many hours you
slept, and if you are still tired or if
you feel well rested, and try and
recall any dreams that you had
27. Dream Questions:
Do your dreams relate to what you
did the day before?
As you start writing down your
dreams do they become able to
recall?
28. “dreaming permits each and every one of
us to be quietly and safely insane every
night of our lives.” –William C. Dement
Sometimes known as the “father of
sleep medicine”
Is a US sleep researcher
Founded the worlds first sleep
laboratory which is found at Stanford
university
Studies sleep deprivation and
treatment of sleep disorders.
29. The five characteristics of
dream consciousness
1. Feel emotion (fear, happiness,
love)
2. be in one place and then in another
with out any travel
3. still have sensation (vision)
4. uncritical acceptance (normal)
5.difficulty remembering
30. Nightmares
An average college student has about
24 nightmares a year.
Some people have nightmares as
often as once a night
Children have more nightmares than
adults
People who have experienced
traumatic events are more likely to
have nightmares than people that
don’t
31. Dreams
“Day residue”- where a current
problem pops into the dream
Dreams pull images from your
everyday life to make them seem
more surreal, and also images from
your past.
32. Dream Theories
In the first psychological theory of
dreams Sigmund Freud he proposed
that dreams were confusing and
obscure because the dynamic
unconscious creates them to be.
In his theory's dreams represent
wishes and some only express them
in disguised form.
33. example
For Freud's theory in the book it
gives an example on page 250:
A dream about a tree burning down in
the park across the street from where
a friend once lived might represent a
camouflaged wish for the death of
the friend. Though wishing for the
death of a friend is unacceptable, so
it is disguised as a tree on fire.
34. Not all dreams represent hidden
wishes, but some are suppressed
thoughts and some are feeling that
you may have been hiding or
sometimes feelings that you did not
necessarily have.
35. Activations Synthesis
Model
This is the theory that dreams are
produced when the mind attempts to
make sense of random neural activity
that occurs in the brain during sleep.
36. Different types of
dreaming
Day dreaming: you are awake, may be
when bored or tired
Lucid dreaming: when you realize you are
dreaming and can change the dream to
what you like
Recurring dreams: when you get the
same dream many different times
Prophetic dreams: dreams that happen in
real life, that tell the future
Signal dreams:
Epic dreams: when you wake up you feel
like you have realized something, also
known as life changing dreams
Progressive dreams: help you face a fear
or problem
Mutual dreams: when you and someone
else have the same dream
37. Dreams Meaning:
Running away from something or
someone: you need to face
something.. Try turning around and
asking them why they are chasing
you.
Falling: you are afraid of something
and are afraid of failing, or paranoid.
Teeth falling out: you are self
conscious, afraid of what someone
might think of you
