Getting enough sleep is essential for maintaining good health and well-being throughout your life. The way you feel during the day is partly dependent on what happens while you are sleeping. During sleep, your body works to support healthy brain function and maintain your physical health. In children and teens, sleep is also essential for supporting growth and development. Inadequate sleep over time can increase your risk of chronic health problems. It can also affect your ability to think, react, work, learn, and interact with others. You can learn more about how sleep affects your heart and circulatory system, metabolism, respiratory system, and immune system, as well as how much sleep is necessary.


Heart and circulatory system:

During non-REM sleep, your blood pressure and heart rate decrease. During sleep, your parasympathetic system controls your body, and your heart does not work as hard as it does when you are awake. During REM sleep and upon waking, your sympathetic system is activated, increasing your heart rate and blood pressure to their usual levels when you are awake and relaxed. A sharp increase in blood pressure and heart rate upon waking has been linked to chest pain and heart attacks.

People who do not get enough sleep or wake up frequently during the night may have a higher risk of coronary heart disease, high blood pressure, obesity, and stroke.


Hormones and sleep:

Your body produces different hormones at different times of the day, which may be related to your sleep pattern or circadian clocks. In the morning, your body releases hormones that promote alertness, such as cortisol, which helps you wake up. Other hormones have 24-hour patterns that vary throughout your life. For example, in children, the hormones that tell the glands to release testosterone, estrogen, and progesterone are made in pulses at night, and the pulses get bigger as puberty approaches.


Metabolism and sleep:

The way your body handles fat varies according to various circadian clocks, including those in the liver, fat, and muscle. For example, the circadian clocks ensure that your liver is prepared to help digest fats at suitable times. Your body may handle fat differently if you eat at unusual times.

Studies have shown that not getting enough quality sleep can lead to higher levels of the hormones that control hunger, including leptin and ghrelin, decreased ability to respond to insulin, increased consumption of food, especially fatty, sweet, and salty foods, decreased physical activity, and metabolic syndrome. All of these contribute to overweight and obesity.


Respiratory and immune systems:

During sleep, you breathe less often and less deeply and take in less oxygen. These changes can cause problems in people who have health problems such as asthma or chronic obstructive pulmonary disease (COPD). Asthma symptoms are usually worse during early morning sleep. Similarly, breathing problems in people who have lung diseases such as COPD can become worse during sleep.

Sleep also affects different parts of your immune system, which becomes more active at different times of day. For example, when you sleep, a particular type of immune cell works harder. That is why people who do not get enough sleep may be more likely to get colds and other infections.


Problems with thinking and memory:

Sleep is crucial for learning and forming long-term memories. Not getting enough sleep or enough high-quality sleep can lead to problems focusing on tasks and thinking clearly. 

Choosing the right Mattress / Bed

Getting a good night's sleep is essential for proper functioning during the day. To achieve that, you need a comfortable and supportive bed that allows you to sleep without any discomfort such as being too hot or too cold, experiencing skin irritation, or any other factors that may interfere with your sleep quality. Considering the amount of time you spend in bed, choosing the right mattress or bed is crucial for your overall well-being and progress throughout your waking hours.
