How many hours of sleep per night are essential

It is our body that asks us, it is it that gives us clear signals when our rest is lacking both in duration and quality but we are not always able to grasp them. Apart from daytime sleepiness, which many consider chronic and to be accepted when it is not, practically a losing battle from the start, a bad rest leads for example to forget things, to not remember names or streets that until yesterday came to mind, numerous studies have shown that sleep is not only a process of physical and mental recovery, but plays a crucial role in eliminating toxins from the brain, including the beta-amyloid protein, one of the main causes of neurodegeneration associated with Alzheimer's. On average, the human body needs 7-9 hours of rest, a period of time that allows for more rest cycles needed for the regeneration of essential cells.

Hours of sleep by age group

Obviously in pre-adolescence and obviously in childhood, they are more. Below are the hours of sleep needed by age:

How Much Sleep Do Babies and Toddlers Need

Newborns (0-3 months) need about 14-17 hours of sleep a day, while toddlers (4-12 months) need 12-16 hours, including any nap breaks. In early childhood (1-2 years), the need drops slightly to 11-14 hours, and preschoolers (3-5 years) are recommended to get 10-13 hours of sleep. As they grow, school-age children (6-12 years) should get between 9 and 12 hours of sleep a night.

Sleep Hours for Teens Ages

13-18 Teens (13-18 years) need 8-10 hours to ensure proper physical and mental development. However, many teens get less sleep than they need due to school, social activities, and use of electronic devices before bed.

Sleep Needs for Adults

Adults (18-64 years) typically need 7-9 hours of sleep per night, although some people can function well on 6 hours, while others require at least 10 hours to feel rested. Quality sleep is essential for concentration, productivity, mood regulation, and disease prevention.

As people age, sleep needs remain similar, but the quality often declines. Older adults (65 and older) should get 7 to 8 hours of sleep, but sleep often becomes lighter and more fragmented, making good sleep habits important for maintaining cognitive and physical health.

What are the risks of too little sleep

Too little sleep can have serious health consequences. Chronic sleep deprivation is linked to an increased risk of cardiovascular disease, diabetes, obesity, depression, and cognitive decline. Inadequate sleep also weakens the immune system and increases the likelihood of infections. Last but not least, it promotes Azheimer's.

Too much sleep is bad

Is sleeping too long bad? Even oversleeping can be harmful. Some studies suggest that prolonged sleep (more than 9-10 hours a night in adults) is associated with an increased risk of chronic diseases, including cardiovascular problems and metabolic disorders.

To improve the quality of your sleep, it is recommended to adopt a regular routine, avoid caffeine and alcohol before bed, reduce the use of electronic devices in the evening, practice physical activity and create an environment conducive to rest, with an adequate temperature and a comfortable mattress.

Conclusions

In conclusion, sleeping the right number of hours is essential for a healthy life. The quality of sleep is as important as the quantity and should be a priority for anyone who wants to improve their overall well-being.
