Lack of sleep can have adverse effects on your body. Many studies have suggested an association between sleep restriction and negative changes in metabolism.

Here you will know that how nut shutting eye properly to the required time can impact your health.

Researchers say that lack of sleep leads to weight gain and an increase in body mass index.  The extra weight can lead to health issues such as high blood pressure, type 2 diabetes, and coronary artery disease.

Experts also said caffeine and alcohol intake, as well as impulsive behaviors, can result in poor sleep. Health officials recommend people set a regular bedtime and wake-up time and make sure their bedroom is primarily for sleep.

Required Hours

The number of hours of necessary sleep can vary based on age. For most adults, 7 to 8 hours is ideal, while 9 hours is required for adolescents, 10 to  11 hours for schoolers, 12 hours for toddlers (1 to 3 years old), and 14 to 15 hours for infants.

According to the experts, the healthiest sleep is to have a regular bedtime and wake-up time.

The decline in Anxiety Levels

According to a researcher at the University of California, Berkeley, 30% of the anxiety can trigger up if a person has a sleepless night.

Moreover, the researchers have come across the type of sleep that can calm the brain and reset it from being anxious through deep sleep.

The sources say that the type is also known as non-rapid eye movement (NREM) slow-wave sleep. The neural oscillations become highly synchronized in this state, and the heart rates and blood pressure drops.

Matthew Walker, a UC Berkeley professor of neuroscience and psychology, said that they had found a new function of deep sleep that can help in reducing anxiety overnight by reorganizing connections in the brain.

The researcher at the University of California, Berkeley, conducted various experiments using functional MRI and polysomnography and scanned 18 young adults’ brains as they were watching warmly rousing video clips both after a full night and sleepless night sleep.

After the night of no sleep, the result shows that the brain scans showed a cessation of the medial prefrontal cortex, which monitors our anxiety. However, in the full sleep nigh, the anxiety levels decayed significantly, particularly for the ones who experienced more slow-wave NREM sleep, the sources said.
