Sleeping on a mattress by Carpe Diem Beds of Sweden

How much sleep do we need

  • The amount of sleep we need is very individual. Age and genetics affect the individual need.

  • Generally, an adult sleeps between 6½ and 7½ hours a night. Older people however sleep less.

  • It has been proven that sleeping for more than 10 hours or less than 5 hours a night leads to an increased risk for illness.

  • Sleep is divided into phases, the most important of which is deep sleep, when even our immune system is strengthened.

  • Waking up in the middle of the night several times is not normal.

  • People with depression have little or no deep sleep.

  • Coffee and alcohol have a negative affect on deep sleep, as does a high room temperature.

What happens if we sleep too little?

  • Levels of the stress hormone, cortisol, drop while you are sleeping.

  • If you are suffering from a lack of sleep, cortisol will remain at a high level, thus slowing the body’s metabolism.

  • People getting too little sleep experience an increased desire for sugar and fat, starch-rich food. This is caused by the level of the hormone leptin - which regulates the feeling of hunger and satisfaction - dropping as a result of lack of sleep.

  • Several independent medical surveys have shown that on average 5 kg overweight is caused by lack of sleep.

  • Lack of sleep is one of the causes of high blood pressure. High blood pressure is a factor that causes premature aging and shortens lives, as it wears out the body.

  • Fatigue depression is almost solely caused by lack of sleep.

Your choice of bed is important for your health

  • Lack of sleep leads to stress.

  • Stress leads to inferior sleep, which in turn can lead to anxiety, pain sensitivity and over time even to fatigue depression.

  • Sleep is the body’s repair period.

  • The body recuperates, and processes and stores information.

  • A major portion of all learning occurs during sleep.

  • If we sleep too little, the risk of higher levels of blood lipids also increases, which can put pressure on the heart and arteries as early as the age of 30.

  • A lack of sleep has a negative effect on the body’s immune system and infection sensitivity increases.

  • Too little sleep can give rise to memory and concentration difficulties and we can easily become irritated and gloomy.

  • Aches and pains are often worsened as a result of lack of sleep.
