We only have 24 hours in a day but with so many tasks to do, endless things to achieve, and restlessness from social media, people are getting less and less sleep.

If you’re one of the many have not added sleep to their list of priorities, think again.

Here are 7 science-backed reasons why you should be getting more shuteye.

  • 01Poor, disrupted sleep increases your risk of Alzheimer’s disease.

    Alzheimer's is a disease where the brain cells die thereby causing a slow decline in memory, thinking, behavior and reasoning skills.

    A 2017 study showed that just one night of poor, disrupted sleep increases levels of some proteins that are associated with Alzheimer's disease. What’s worse? A week of bad sleep leads to an increase in another brain protein that has been linked to brain damage in Alzheimer’s and other neurological diseases.

  • 02Insufficient sleep impairs memory and learning.

    It is during sleep that the brain consolidates and solidifies what we learn and use the information when we’re awake.

    Early this year, scientists have fortified evidence that sleep deprivation, sleeping pills and sleep disorders interfere with the brain’s “consolidation” process. The result? Stymied learning and loss of memory.

  • 03Lack of sleep will make you fat.

    In 2012, researchers found that getting fewer than six hours sleep is linked to increased body max index (BMI) or obesity. How? Insufficient sleep impacts the release of hormone that increases appetite (ghrelin) and the hormone that indicates when you’re full (leptin) – this leads to increased food intake without the compensating energy expenditure.

    A 2017 study adds that acute sleep loss alters the balance of gut bacteria, which has been widely implicated as key for maintaining a healthy metabolism.

  • 04Inadequate sleep speeds up skin aging.

    Women who get poor sleep show increased signs of aging and slower recovery from aggressors such as UV sun radiation. The 2013 study proved that those who have bad quality of sleep had reduced skin health and had lower satisfaction about their own appearance.

  • 05Lack of sleep leads to insulin resistance.

    Insulin regulates sugar levels in the body, and when the body becomes less sensitive to insulin (becoming resistant), there’ll be too much sugar in the blood. This could lead to diabetes.

    A 2012 study proposes that increasing the amount of sleep could improve insulin resistance and prevent the future onset of diabetes.

  • 06Too little sleep takes a toll on your heart.

    In 2016, researchers found that short-term sleep deprivation leads to a significant increase in cardiac contractility, blood pressure, heart rate and stress hormone secretion.

    It is also said that poor sleep increases the risk of heart attack and stroke. Findings show that men with a sleeping disorder had twice the risk of heart attack and up to four times the risk of stroke than men who had good sleep.

  • 07Partial sleep deprivation promotes biological aging in older adults.

    A study released by the American Academy of Sleep Medicine in 2015 suggests that one night of partial sleep is linked to accumulation of damage that triggers cell cycle arrest and senescence. Senescent cells are alive but have lost the ability to reproduce themselves.

    If your cells can’t reproduce to keep your body functioning or to heal yourself, you’ll be at a greater risk of developing diseases.

We need to keep proper diet, stay active and good quality of sleep to stay healthy. If you’re having trouble sleeping, consult a doctor right away.
