Sleep is a necessary aspect of life and is essential to our health. The quantity and quality of your sleep can have a powerful impact on how you feel during the day—from your emotional state to your brain function. In fact, when people get less than 6 or 7 hours of sleep each night, their risk for developing diseases begins to increase.

Here are a most important benefits of the good night’s sleep:

1. Sleep keeps your heart healthy

Heart attacks and strokes are more common during the early morning hours. This fact may be explained by the way sleep interacts with the blood vessels. 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 keeps  moods

Over time, losing sleep may lead to irritability and changes in your moods. Getting enough sleep can help you maintain a more even temperament and help you deal better with everyday stress.

3. Improves your memory

That ‘foggy’ feeling that you struggle with when deprived of sleep makes it difficult to concentrate. This often leads to not being able to ‘commit to memory’ facts, faces, lessons or even conversations! Sleeping well eliminates these difficulties because as you sleep, your brain is busy organizing and correlating memories. One of the great benefits of sleep is that it allows your brain to better process new experiences and knowledge, increasing your understanding and retention.

4. Sleep may prevent cancer

People working the late shift have a higher risk for breast and colon cancer. Researchers believe this link is caused by differing levels of melatonin in people who are exposed to light at night. Light exposure reduces the level of melatonin, a hormone that both makes us sleepy and is thought to protect against cancer. Melatonin appears to suppress the growth of tumors. Be sure that your bedroom is dark to help your body produce the melatonin it needs.

5. 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 obese. It is thought that the lack of sleep impacts the balance of hormones in the body that affect appetite. The hormones ghrelin and leptin, important for the regulation of appetite, have been found to be disrupted by lack of sleep. So if you are interested in controlling or losing weight, don’t forget to pay attention to getting a good night’s sleep.

6.Sleep helps to repair your body

Your body produces extra protein molecules while you’re sleeping, and these help to mend your body at a cellular level. The damage from all kinds of things, such as stress, pollutants, infection, sun exposure and so on, is repaired while you’re happily in the land of nod.

7. Sleep  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.
