Water requirement for human body


Water is an important structural component of skin cartilage, tissues and organs. For human beings, every part of the body is dependent on water. Our body comprises about 75% water: the brain has 85%, blood is 90%, muscles are 75%, kidney is 82% and bones are 22% water. The functions of our glands and organs will eventually deteriorate if they are not nourished with good, clean water.

The average adult loses about 2.5 litres water daily through perspiration, breathing and elimination. Symptoms of the body's deterioration begins to appear when the body loses 5% of its total water volume. In a healthy adult, this is seen as fatigue and general discomfort, whereas for an infant, it can be dehydrating. In an elderly person, a 5% water loss causes the body chemistry to become abnormal, especially if the percentage of electrolytes is overbalanced with sodium.One can usually see symptoms of aging, such as wrinkles, lethargy and even disorientation. Continuous water loss over time will speed up aging as well as increase risks of diseases.

If your body is not sufficiently hydrated, the cells will draw water from your bloodstream, which will make your heart work harder. At the same time, the kidneys cannot purify blood effectively. When this happens, some of the kidney's workload is passed on to the liver and other organs, which may cause them to be severely stressed. Additionally, you may develop a number of minor health conditions such as constipation, dry and itchy skin, acne, nosebleeds, urinary tract infection, coughs, sneezing, sinus pressure, and headaches.

How much sleep is enough among age groups ?


Every person is unique and so are our sleep needs. But in today’s busy world, how much sleep should we be getting each night?

Research suggests that most healthy adults need seven to nine hours of sleep each night. Children and adolescents need even more sleep than adults. The following is a breakdown of the recommended number of hours of sleep people need by age (*including naps):

INFANTS

(0 to 2 months): ................10-1/2 to 18 hours*

(2-12 months): ...........................14 to 15 hours*

TODDLERS/CHILDREN

(12-18 months): ........................13 to 15 hours*

(18 months-3 years): ...............12 to 14 hours*

(3-5 years): ..................................11 to 13 hours*

(5-12 years): ....................................9 to 11 hours

ADOLESCENTS

8-1/2 to 9-1/2 hours

ADULTS

7 to 9 hours

Women sleep and pain


More women (58%) suffer from nighttime pain than men (48%), according to a 1996 NSF Gallup Poll. In a more recent 2000 NSF Sleep in America poll, one in four women reported that pain or physical discomfort interrupted their sleep three nights a week or more.

Pain conditions like migraine, tension headaches, rheumatic and arthritis conditions as well as heartburn are all more common among women. Pain may make it harder to fall asleep or lead to nighttime or early morning awakenings. Relaxation techniques, biofeedback, cognitive therapy, and over-the-counter and prescription medications may help. Treatment may target the pain, the sleeping difficulty, or both.

Unique sleep experiences of Women


Although most people need seven to nine hours of sleep each night to function well the next day, the National Sleep Foundation (NSF) 1998 Women and Sleep Poll found that the average woman aged 30-60 sleeps only six hours and forty-one minutes during the workweek.

A more recent 2005 NSF Sleep in America poll of all adults revealed that women are more likely than men to have difficulty falling and staying asleep and to experience more daytime sleepiness at least a few nights/days a week. Research has shown that too little sleep results in daytime sleepiness, increased accidents, problems concentrating, poor performance on the job and in school, and possibly, increased sickness and weight gain.

Getting the right amount of sleep is vital, but just as important is the quality of your sleep. Biological conditions unique to women, like the menstrual cycle, pregnancy and menopause, can affect how well a woman sleeps. This is because the changing levels of hormones that a woman experiences throughout the month and over her lifetime, like estrogen and progesterone, have an impact on sleep. Understanding the effects of these hormones, environmental factors and lifestyle habits can help women enjoy a good night’s sleep.

Sleep Drive and Your Internal Body Clock


Sleep is regulated by two body systems they are sleep/wake homeostasis and the circadian biological clock.

When we have been awake for a long period of time, sleep/wake homeostasis tells us that a need for sleep is accumulating and that it is time to sleep. It also helps us maintain enough sleep throughout the night to make up for the hours of being awake. If this restorative process existed alone, it would mean that we would be most alert as our day was starting out, and that the longer we were awake, the more we would feel like sleeping. In this way, sleep/wake homeostasis creates a drive that balances sleep and wakefulness.

Our internal circadian biological clocks, on the other hand, regulate the timing of periods of sleepiness and wakefulness throughout the day. The circadian rhythm dips and rises at different times of the day, so adults' strongest sleep drive generally occurs between 2:00-4:00 am and in the afternoon between 1:00-3:00 pm, although there is some variation depending on whether you are a “morning person” or “evening person.” The sleepiness we experience during these circadian dips will be less intense if we have had sufficient sleep, and more intense when we are sleep deprived. The circadian rhythm also causes us to feel more alert at certain points of the day, even if we have been awake for hours and our sleep/wake restorative process would otherwise make us feel more sleepy.

Changes to this circadian rhythm occur during adolescence, when most teens experience a sleep phase delay. This shift in teens' circadian rhythm causes them to naturally feel alert later at night, making it difficult for them to fall asleep before 11:00 pm. Since most teens wake up early for school and other commitments, this sleep phase delay can make it difficult to get the sleep teens need -- an average of 9 1/4 hours, but at least 8 1/2 hours. This sleep deprivation can influence the circadian rhythm; for teens the strongest circadian “dips” tend to occur between 3:00-7:00 am and 2:00-5:00 pm, but the morning dip (3:00-7:00 am) can be even longer if teens haven’t had enough sleep, and can even last until 9:00 or 10:00 am.

The circadian biological clock is controlled by a part of the brain called the Suprachiasmatic Nucleus (SCN), a group of cells in the hypothalamus that respond to light and dark signals. From the optic nerve of the eye, light travels to the SCN, signaling the internal clock that it is time to be awake. The SCN signals to other parts of the brain that control hormones, body temperature and other functions that play a role in making us feel sleepy or awake.

In the mornings, with exposure to light, the SCN sends signals to raise body temperature and produce hormones like cortisol. The SCN also responds to light by delaying the release of other hormones like melatonin, which is associated with sleep onset and is produced when the eyes signal to the SCN that it is dark. Melatonin levels rise in the evening and stay elevated throughout the Circadian disruptions such as jet lag put us in conflict with our natural sleep patterns, since the shift in time and light cues on the brain forces the body to alter its normal pattern to adjust. This is why jet lag can leave travelers feeling poorly and having more difficulty thinking and performing well. But these symptoms can also occur in everyday life, when the circadian rhythm is disrupted by keeping long and irregular hours. Because of this, it is important to keep a regular sleep schedule and allow plenty of time for quality sleep, allowing these two vital biological components -- the sleep/wake restorative process and the circadian rhythm -- to help us perform at our best.

Good sleeping environment is vital


Create a sleep-conducive environment that is dark, quiet, comfortable and cool.


Design your sleep environment to establish the conditions you need for sleep – cool, quiet, dark, comfortable and free of interruptions. Also make your bedroom reflective of the value you place on sleep. Check your room for noise or other distractions, including a bed partner's sleep disruptions such as snoring, light, and a dry or hot environment. Consider using blackout curtains, eye shades, ear plugs, "white noise," humidifiers, fans and other devices.


Sleep on a comfortable mattress and pillows.


Make sure your mattress is comfortable and supportive. The one you have been using for years may have exceeded its life expectancy – about 9 or 10 years for most good quality mattresses. Have comfortable pillows and make the room attractive and inviting for sleep but also free of allergens that might affect you and objects that might cause you to slip or fall if you have to get up during the night.
