Whether you are a nude sleeper, a comfy pair of winceyette pyjama wearer or a knickers and t-shirt type of guy, sleep is really good for you. Below are some of the reasons it’s good to get your head down and start counting those sheep.
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
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 tumours. Be sure that your bedroom is dark to help your body produce the melatonin it needs.
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.
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, diabetes and is thought to one of the causes of the deterioration of your body as you age.
5. Sleep Makes You More Alert
Of course, a good night’s sleep makes you feel energized and alert the next day. Being engaged and active not only feels great, it increases your chances for another good night’s sleep.
6. Sleep Bolsters Your Memory
Researchers do not fully understand why we sleep and dream, but a process called memory consolidation occurs during sleep. While your body may be resting, your brain is busy processing your day, making connections between events, sensory input, feelings and memories.
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 obese. It is thought that the lack of sleep impacts the balance of hormones in the body that affect appetite.
8. Naps Make You Smarter
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.
