Sleep plays an important role in the proper functioning of the body. This moment of rest allows memory to enhance and keep the brain in good shape. In addition, lack of sleep can cause serious health problems. Here’s what to do to sleep better and live longer.
On average we sleep 7 to 8 hours a day, but this period varies from one person to another, and some feel rested with 6 hours of sleep.
Lack of sleep can cause serious health problems such as diabetes, osteoporosis or memory loss. Therefore, it is advisable not to neglect the sleep hours.
What to avoid in order to sleep better
According to the Daily Mail, scientists recommend to turn off all electronic devices before bedtime because they can disrupt the sleep and cause serious health problems. Indeed, electronic devices such as telephone or computer may emit radiation that has the ability to alter the body’s DNA. In addition, a scientific study conducted in 2009 showed that electromagnetic radiation from cell phones could decrease the bone density and affect the quality of the sperm by disrupting its mobility.
A link has also been established between the cell phone and cancer. Indeed, Dr. Siegal Sadetzki published a study in 2008 concluding that:
- Regular use of the telephone for more than 5 years increases the risk of cancer by 34%.
- The risk of cancer increases by 58% if you have received more than 5,500 calls from your first use of cell phone.
- If you talk on the phone more than 266.3 hours in your life, the risks increase by 49%.
Cell phones: health consequences
A study by the Swedish researchers at the Karolinska Institute, Uppsala University and US researchers from the Wayne State University, proves that rays produced by cell phones delay sleep, cause headaches, blur the mood, cause depressive symptoms and lack of concentration.
To get to these results, the scientists studied 35 men and 36 women between ages of 18 and 45. These volunteers were divided into two groups: one was exposed to radiation similar to those produced by a cell phone, while the latter believed to be exposed to this type of radiation. Experts have concluded that people in the first group were struggling to enter the deep sleep cycle and were affected by recovery of daily fatigue.
Artificial light: health consequences
According to Harvard researchers, artificial light affects the production of a hormone called melatonin, which plays an important role in promoting sleep. They discovered that keeping the light on until bedtime prevents the body to normally synthesize melatonin because it is then produced with 90 minutes delay. The European Commission has also raised concerns about the use of artificial light.
Therefore, it is advisable to avoid bad habits like keeping the lights on, the phone or the TV in the room. Your room must not contain any electronic device for a perfect sleep in order not to feel tired the next day.
