Researchers have found yet another reason why you should get enough sleep. Research has revealed that sleep is very beneficial to the immune system. German researchers have discovered that sound sleeps helps to improve the immune cells called T cells.
According to Stoyan Dimitrov, a University of Tübingen researcher and the study’s author, these cells are immune cells that help the body fight against diverse intracellular pathogens such as cancer cells, herpes, and HIV.
The study highlighted a new mechanism showing how sleep helps the immune system. According to Dimitrov, the study shows that stress hormone adrenaline which is also called epinephrine and noradrenaline, known as norepinephrine as well as molecules prostaglandins that are pro-inflammatory prevent the stickiness of adhesion molecules known as integrins.
Owing to the fact that the levels of prostaglandins, noradrenaline and adrenaline are quite low when we sleep, integrins’ stickiness is much stronger during this period.
The stickiness is quite essential because for T cells to effectively kill cancer or virus-infected cells, they have to be in direct contact with these cells. This integrin stickiness helps to facilitate that contact.
T Cells And Their Importance
The role of T cells in the immune system is a very important one. When the body cells detect the presence of a cell that has been infected with a virus, they activate the integrins, and that gives room for attachment to these cells and eventually killing the infected cells.
In addition, the researchers looked at the T cells gotten from healthy volunteers, I.e. People who either slept all night or stayed awake all through the night. They discovered that participants who fell into the category of those who slept had T cells stayed awake. Also, the study found that sleep possesses the potential to help in the improvement of T cell functioning.
For persons who don’t get enough sleep, their stress hormones may prevent the T cells from functioning effectively. Dimitrov explained that there is a dip in stress hormones when the body sleeps and when the substances are at high levels, there would be a drop in the ability of T cells to kill these pathogens.
Sleep And Its Importance
Research reveals that adults need not less than 7 hours of sleep daily to improve their health and general well-being. According to Kimberly Hardin, a sleep medicine fellowship program’s director at the University of California Davis, a lot of people don’t understand the importance of good sleep, and so they take it for granted.
Hardin stated that sleep is often under-estimated by several people and sleeping for less than 7 hours every night regularly has diverse negative effects. It increases the stress hormones as well as adrenaline release.
Hardin said sleep is a natural state, one we have to take care of so we can stay healthy. Sleep is an activity that should ordinarily leave one feeling refreshed and not struggling.
It is true that sleep pattern changes as one age and it is possible that you do not feel the level of rest you felt when you were much younger.
Sleeping for less than 5 hours every night regularly is tied with higher mortality. Sleeping for less than 7 hours every night for three nights in a row also affects the body in the same way as missing one whole night of sleep. Having a poor sleep pattern has both long-term and short-term consequences.
A sleep neurologist, Suzanne Stevens said bad sleep has the tendency to cause long-term issues with memory, mood, blood sugar and a host of other issues.
Short And Long Term Effects Of Bad Sleep
The short-term effects of bad sleep include poor judgment, moodiness, sleepiness, workplace mistakes, car accidents, and memory problems, among other issues.
Having a poor sleep does not affect only a person’s ability to function effectively the next day, a buildup of sleep deficit is not good.
Also, poor sleep tends to increase blood pressure, inflammation, cortisol, insulin resistance, cardiovascular disease and a decrease in blood sugar regulation.
Also, having a good night sleep reportedly helps to protect the heart against heart disease. The result of a study conducted in mice revealed that a connection exists between the bone marrow, blood vessels, and brain.
