The skin is an organ and just like all the other organs in your body, it is made up of cells. Since the cells are made up of water, they need water to function properly. Lack of hydration can cause skin issues such as dry, tight skin which might lead to flaking. Because of constant perspiration, your body loses the vital minerals and salts and that is the reason why your body needs daily replenishing.
What happens to the skin, if you do not drink sufficient water in a day?
The outermost layer, which is known as the ‘epidermis’
The layer beneath it is called the ‘dermis’
The subcutaneous tissue
Usually, water loss takes place from the epidermal layer of the skin due to sweating, however, if the cells in the underlying layers are not hydrated enough, the epidermis begins to start feeling rough and loses its elasticity which can lead to degradation of its texture.
Sufficient water intake and skin - the connect
Drinking water also flushes out the dangerous toxins from within your body and your skin, which allows your skin to breathe normally again. With the normal function restored in the skin, the cells do not feel trapped or inadequate, which means they can continue with their normal functions. This helps delay skin aging by adding shine to your skin.
You should be aiming to drink 8 -10 glasses of water each day because a lesser amount can cause dehydration. Dehydration may trick the oil glands in your body into believing that they need to produce more oil which leads to an excess production of oil, thus, increasing the chance of acne.
Also, when your skin is hydrated from inside, it looks plumper and more radiant and can hide signs of aging. However, when witnessed at a histopathological level [when examined under a microscope], the signs of aging are still present but because your skin is hydrated and looks younger, these signs are invisible to the naked eye. If you wish to discuss about any specific problem, you can consult a dermatologist and ask a free question.
