Sleep is very important. While we are asleep our body is in ‘repair mode’, during which it releases growth hormone which act to stimulate the production of collagen - the tissues in our body are being replenished as we sleep. Poor sleep, or no sleep, can slow down this process, so when excess alcohol leads to poor sleep, our collagen level suffers.
High stress levels can impact our collagen levels by affecting our sleep, but also because of the very nature of the stress itself. Our main stress hormone, Cortisol, actually breaks down proteins to provide us with the energy our stressed body thinks it needs ,and one of the most plentiful proteins in our body is collagen! Long term, chronic stress can be linked to the loss of collagen in skin, joints etc, which causes the body more stress…and so it goes on!
A diet high in sugar is bad for your overall health, and, of course, it adversely affects your collagen level as well.
A high-sugar diet can lead to an increased rate of glycation - this is where sugar molecules in food bind to protein molecules in the skin. Collagen is a protein, and so when glycation happens, the collagen in the body becomes less flexible, more fragile and more easily broken.

To give yourself the best chance to maintain your natural collagen levels, use a good-sunscreen, avoid air pollution, don’t smoke, don’t drink excessive amounts of alcohol, reduce your stress, sleep well, and eat very little sugar.
