Getting enough sleep every night is essential for your overall health. While you are sleeping your body is getting the rest it needs. However, many people suffer from sleeping disorders such as insomnia which is the main cause of many health issues. The amount of time you should sleep depends on your age, sex and level of activity.
Sleeping disorders can be caused by various factors such as stress and modern lifestyle and technology. Stress is the leading cause of sleep disorders because it increases cortisol secretion, a hormone that can cause discomfort, sickness and inability to sleep.
Using technological devices can also have negative effects on your ability to sleep because the light they emit blocks the melatonin production.
Having unhealthy sleeping patterns will make you unable to think clearly, concentrate, make decisions and even eat.
Sleeping less than 5 hours a night makes your heart suffer a lot. And sleeping less than 7 hours could cause health issues such as diabetes or weight gain.
