Waking up after a bad night’s sleep and feeling tired is not just an impression: sleep has a direct impact on the health and appearance of our skin, and even affects the way others perceive us.
Research has analyzed the effects of sleep deprivation
Research published in ScienceDirect investigated the effects of sleep deprivation. In one trial, 24 women ages 30 to 55 had their rest period reduced by three hours, on average, for two consecutive days. The results showed noticeable changes in the skin, such as increased loss of natural moisture, thus causing it to dry out, lose its elasticity, and a slight increase in pH, which may make it more sensitive.
According to a study published in the Oxford Journal of Neuroendocrinology, growth hormone GH is released during deep sleep. It promotes repair and rebuilding processes, helping the skin heal tissue, restore muscle and increase the production of collagen, the protein responsible for maintaining skin firmness and elasticity.
In addition, cortisol, the body’s main stress hormone, drops to its lowest levels during this phase. Low rates protect collagen, reduce inflammation, and strengthen the skin barrier. High levels of prolactin, a hormone that helps regulate the immune system and cell growth, intensify tissue repair, helping the skin recover from daily stressors.
A good night’s sleep changes skin health
According to dermatologist Dr. Isabella Dubin, Professor of Medical Education at Afia, a good night’s sleep is one of the cornerstones of healthy skin. “Sleep acts like a real free ‘night therapy’: as we sleep deeply, the skin goes into intense repair mode. This happens when there is greater collagen production, reducing inflammation and strengthening the skin barrier. When we neglect this rest, we directly put these mechanisms at risk, and the skin responds with visible signs of fatigue and aging.”
Getting a good night’s sleep brings social reactions
In addition to biological effects, good sleep also has social consequences. A survey conducted by the Royal Society proved that certain facial and body cues influence how people are perceived. Sleep-deprived individuals report being less optimistic and sociable, having more difficulty understanding and expressing emotions, being less empathetic and more prone to accidents.
Sleep is a good investment
“Investing in a proper sleep routine is no less important than using good cosmetics or maintaining a balanced diet. When we sleep well, our body works to our advantage: the skin is renewed, signs of fatigue are reduced, and even the way we present ourselves to the world improves. Sleep is a powerful and accessible self-care tool, and when we understand it, we can enhance the results of any other beauty or well-being strategy,” concludes Dr. Isabella Dubin.
