Explain the factors that play a role in preparing your body to fall asleep and wake up.
Answer:
Sleep in the Real World
The internal mechanisms that regulate our almost ceaseless cycles of sleep and wakefulness make up a remarkable system. However, a variety of internal and external factors can dramatically influence the balance of this sleep-wake system.
Changes in the structure and function of the brain during development can have profound, if gradual, effects on sleep patterns. The amount of sleep we obtain generally decreases and becomes more fragmented throughout our lifespan. These and other variations associated with age are covered at length in the essay Changes in Sleep with Age.
Other factors that affect sleep include stress and many medical conditions, especially those that cause chronic pain or other discomfort. External factors, such as what we eat and drink, the medications we take, and the environment in which we sleep can also greatly affect the quantity and quality of our sleep. In general, all of these factors tend to increase the number of awakenings and limit the depth of sleep.
Light's Effect
Light exposure can cause our biological clock to advance or delay, which affects our sleep and wake cycle.
Light is one of the most important external factors that can affect sleep. It does so both directly, by making it difficult for people to fall asleep, and indirectly, by influencing the timing of our internal clock and thereby affecting our preferred time to sleep.
Light influences our internal clock through specialized "light sensitive" cells in the retina of our eyes. These cells, which occupy the same space as the rods and cones that make vision possible, tell the brain whether it is daytime or nighttime, and our sleep patterns are set accordingly.
Due to the invention of the electric lightbulb in the late 19th century, we are now exposed to much more light at night than we had been exposed to throughout our evolution. This relatively new pattern of light exposure is almost certain to have affected our patterns of sleep. Exposure to light in the late evening tends to delay the phase of our internal clock and lead us to prefer later sleep times. Exposure to light in the middle of the night can have more unpredictable effects, but can certainly be enough to cause our internal clock to be reset, and may make it difficult to return to sleep.
Jet Lag and Shift Work
Normally, light serves to set our internal clock to the appropriate time. However, problems can occur when our exposure to light changes due to a shift in work schedule or travel across time zones. Under normal conditions, our internal clock strongly influences our ability to sleep at various times over the course of a 24-hour period, as well as which sleep stages we experience when we do sleep.
Long-distance travelers experience “jet lag” as their internal clock adjusts to the new day-night cycle.
Individuals who travel across time zones or work the night shift typically have two symptoms. One is insomnia when they are trying to sleep outside of their internal phase, and the other is excessive sleepiness during the time when their internal clock says that they should be asleep. Half of all night shift workers regularly report nodding off and falling asleep when they are at work. This should be seen as an important concern both for individuals and society, given that airline pilots, air traffic controllers, physicians, nurses, police, and other public safety workers are all employed in professions in which peak functioning during a night shift may be critical.
The effects of shift work and jet lag on sleep are covered in much greater detail in Jet Lag and Shift Work and You and Your Biological Clock.
Pain, Anxiety, and Other Medical Conditions
A wide range of medical and psychological conditions can have an impact on the structure and distribution of sleep. These conditions include chronic pain from arthritis and other medical conditions, discomfort caused by gastroesophageal reflux disease, pre-menstrual syndrome, and many others. Like many other sleep disruptions, pain and discomfort tend to limit the depth of sleep and allow only brief episodes of sleep between awakenings.
Individuals of all ages who experience stress, anxiety, and depression tend to find it more difficult to fall asleep, and when they do, sleep tends to be light and includes more REM sleep and less deep sleep. This is likely because our bodies are programmed to respond to stressful and potentially dangerous situations by waking up. Stress, even that caused by daily concerns, can stimulate this arousal response and make restful sleep more difficult to achieve.
Medications and Other Substances
Many common chemicals affect both quantity and quality of sleep. These include caffeine, alcohol, nicotine, and antihistamines, as well as prescription medications including beta blockers, alpha blockers, and antidepressants.

Answer:
When you exercise, your body needs more oxygen.
Explanation:
Answer:
When you exercise, your body needs more oxygen.
Explanation:
Your body needs more oxygen and creates more carbon dioxide when you exercise and your muscles work harder. Your muscles are working hard during exercise. As your heart rate and breathing rate increase, more oxygen is drawn into the bloodstream. The oxygen that enters your muscles turns available glucose into ATP, giving your body the energy it needs to finish your workout.

The danger of hypothermia is greatest for a person in which situation.
Answer:
Hypothermia is a potentially dangerous drop in body temperature, usually caused by prolonged exposure to cold temperatures. The risk of cold exposure increases as the winter months arrive. But if you're exposed to cold temperatures on a spring hike or capsized on a summer sail, you can also be at risk of hypothermia.
Infants and older adults have the highest risk of developing hypothermia. This is due to a decreased ability to regulate their body temperature. People in these age groups must dress appropriately for cold weather. You should also regulate air conditioning to help prevent hypothermia at home.
Hypothermia develops when the body temperature drops below 35°C. The normal human body temperature is around 37°C. As the body temperature drops below 32°C, hypothermia becomes severe and life threatening.

Mike complains about an itchy pimple on the back of his neck that just won't go away. He says the pimple is the same spot as a birthmark that's been there as long as he can remember. You ask him how long he's had the itchy pimple and he tells u a month or two. Based upon what u learned in this lesson, what advice would you give to mike?
Answer:
the best advice would be to talk to a doctor as soon as he can
Explanation:
Based on the situation being described, the best advice would be to talk to a doctor as soon as he can. This is because this pimple might not be anything or maybe basal cell carcinoma (skin cancer) since this type of cancer usually appears on the individual's head or neck and can resemble a pimple or growth. Therefore, it can be very easy to mistake it for a regular pimple and ignore it when it may be more serious and need to be taken care of by a doctor.

What is cardiorespiratory fitness?The ability of the heart and lungs to provide oxygen to the body's muscles and organs when engaged in physical exercise is known as cardiorespiratory fitness.
The body's capacity to sustain skeletal muscle activity through high rates of aerobic metabolism determines cardiorespiratory endurance. High cardiorespiratory endurance individuals often possess highly functional cardiovascular and respiratory systems (heart, lungs, blood vessels, etc.), and their skeletal muscles are well suited to them.
A complete picture of an individual's fitness level is provided by using more than one assessment. Therefore option C is correct.

Modern days beauty standards are set falsely and they independently are based on media. Many of them alter their posts to make them appear better which sets unhealthy beauty standards for normal people.
Explanation:
Photoshop is a thing nowadays and these people on the media are altering their photos so they can appear better looking. The problem with this is most of them say that this is natural. Younger individuals are believing this and even though they are already perfectly fine, they set out to look like those influencers we see today.
