Too much activity and stress can disrupt sleep patterns and ultimately make us less rest.
“Today, the average adult has time to sleep half an hour less, compared with the average adult 100 years ago,” said Yelena Pyatkevich, MD, director of the division of neurology and sleep disorders clinic at Boston Medical Center.
It is not a good thing. Lack of sleep not only causes us tired and sleepy during the day, but also contribute to the emergence of various diseases.
A sleep expert, Dr. Pyatkevich and Dianne Augelli, MD, New York Presbyterian Hospital and Weill Cornell Medicine in New York, said, this is what happens to our body if we less rest.
1. Do not focus and memory impairment
Lack of sleep, even just overnight, according Augelli, can negatively affect the ability of cognition, memory, learning, and data processing in the brain.
We need to sleep as part of the consolidation process of memory and learning. Keep in mind, these effects are short-term effects. That is, if the next night you get enough sleep, your brain’s ability to return to normal.
2. Mood worsens
“In the long term, lack of sleep can lead to depression and anxiety,” said Augelli. However, interestingly, less sleep a night does not cause depression directly. The first day without sleep may enhance the mood.
“The mood increased probably because the body release certain neurotransmitters and other hormones to make sure that each other awake,” added Augelli.
However, the increase in this mood will not last long. After that, your mood will lead to depression and anxiety, if you still continue to lack of sleep.
3. The skin becomes bleak and eye pockets
Results of a study conducted in 2013 at the University Hospitals of Cleveland and is funded by the skin care products giant Estee Lauder show that there is a correlation between lack of sleep and aging skin. Lack of sleep causes the appearance of wrinkles to dark spots on the skin.
4. Your appetite will skyrocket
“The effects of sleep deprivation may appear in the form of increased appetite,” Augelli said. When lack of sleep, levels of ghrelin hormone increases.
Ghrelin is a hormone that is responsible for giving signals to the brain that you are hungry.
5. Metabolism slows
A slowed metabolism can also occur when you do not get enough sleep. “In the long term, there will be changes in metabolism because your body no longer process food that goes in the same way, creating insulin resistance, your body will tend to keep more of what you eat and not processed as usual,” said Augelli.
Insulin resistance can also create pre-diabetic condition, which if left unchecked will develop into diabetes.
6. Annoying heart health
Sleep is the time when our bodies back to normal and relaxed. At that time, blood pressure and heart rate slowed down as a sign of the body is being carried out repairs.
Loss of sleep means losing the body repair itself and can cause stress hormone levels rise, causing blood pressure to go up so that the heart health deteriorated.
7. decreased athletic performance
Lack of sleep also can decrease sexual desire and athletic performance the next day. It is important for you to get enough sleep, if it wants to maintain athletic performance or ability to exercise and physical activity.
8. Weaken immune system
“Your immune system is impaired when you do not get enough sleep, even if only one night,” said Augelli.
Pyatkevich noted that we tend to be weak in the fight against pneumonia and viral infections when less intermission.
