Sleep & Health

Top 10 Benefits Of Sleep.

(1) Sleep Keeps Your Heart Healthy
Lack of sleep has been associated with worsening of blood pressure and cholesterol, all risk factors for heart disease and stroke. Your heart will be healthier if you get between 7 and 9 hours of sleep each night.

(2) Sleep May Prevent Cancer
Cortisol is the so-called “stress” hormone triggered, along with others, during times of anxiety and may play a role in the development and worsening of cancer and other conditions.
The other hormone affected by sleep is melatonin. Produced by the brain during sleep, melatonin may have antioxidant properties that help prevent damage to cells that can lead to cancer.
In addition, melatonin lowers estrogen production from the ovaries. Thus, a lack of sleep leads to too little melatonin. This series of events may expose women to high levels of estrogen and may increase the risk of breast cancer.
“There’s a definite hormonal pattern that is affected by sleep that in itself, can predict a more rapid progression of cancer.” Sleep is vital to overall health and vitality.
Sleeping is an essential task for almost every living creature, and humans are no exception to this rule. Without sleep, humans become fatigued. Sleep also has implications for the mental and physical health of humans. For this reason, sleep is the most important part of a person’s health.
Already, millions of Americans do not get enough sleep. Some of the lack of sleep is explained by social life, but other parts are due to legitimate sleeping disorders. It turns out that the cardiovascular system does not appreciate the sleep deprivation, whether it stems from choice or from disorder.

(3) Sleep Reduces Stress
When your body is sleep deficient, it goes into a state of stress. The body’s functions are put on high alert which causes an increase in blood pressure and a production of stress hormones. Higher blood pressure increases your risk for heart attacks and strokes.

(4) Sleep Reduces Inflammation
The increase in stress hormones raises the level of inflammation in your body, also creating more risk for heart-related conditions, as well as cancer and diabetes. Inflammation is thought to one of the causes of the deterioration of your body as you age.

(5) Sleep Makes You More Alert
When you wake up feeling refreshed, use that energy to get out into the daylight, do active things, and be engaged in your world. You’ll sleep better the next night and increase your daily energy level.

(6) Sleep Bolsters Your Memory
While your body may be resting, your brain is busy processing your day, making connections between events, sensory input, feelings and memories. Your dreams and deep sleep are an important time for your brain to make memories and links. Getting more quality sleep will help you remember and process things better.

(7) Sleep May Help You Lose Weight
Researchers have also found that people who sleep less than seven hours per night are more likely to be overweight or gain weight. It is thought that the lack of sleep impacts the balance of hormones in the body that affect appetite.

(8) Naps Make You Smarter
Napping during the day is not only an effective and refreshing alternative to caffeine, it can also protect your health and make you more productive. A study of 24,000 Greek adults showed that people who napped several times a week had a lower risk for dying from heart disease. People who nap at work have much lower levels of stress. Napping also improves memory, cognitive function and mood.

(9) Sleep May Reduce Your Risk for Depression
Sleep impacts many of the chemicals in your body, including serotonin. People with a deficiency in serotonin are more likely to suffer from depression. You can help to prevent depression by making sure you are getting the right amount of sleep, between 7 and 9 hours each night.

(10) Sleep Helps the Body Make Repairs
Sleep is a time for your body to repair damage caused by stress, ultraviolet rays and other harmful exposures. Your cells produce more protein while you are sleeping. These protein molecules form the building blocks for cells, allowing them to repair damage.
