1) The beard creates it’s own antibiotic to fight against bacteria and fungus. It’s sort of like the body producing it’s own penicillin.
2) A beard can protect your face from the sun’s damaging rays.
The sun has ultraviolet (UV) rays that harm your skin and cause you to develop skin cancer. While most of your body is shielded by your clothes, your face is always exposed, unless you wear a cap every time you go out in the sun. A beard is perfect because it covers the lower half of your face, thereby reducing the risk of skin cancer significantly.
3) A beard can keep you warm in the winter.
4) Beard’s can fight off diseases of the throat:
The effectiveness of the beard has been documented as far back as 1875! In the book Pulmonary Tuberculosis: Its Pathology, Nature, Symptoms, Diagnosis, Prognosis, Causes, Hygiene, and Medical Treatment, Dr. Addison P. Dutcher noted:
“There cannot be the least doubt that the beard, and the hairs that grow in the nostrils, were designed by nature to guard the lungs from the invasion of these deleterious particles. Such being the use of the beard, individuals engaged in employments where the air is constantly filled with particles of fine dust should never shave. I have come to this conclusion from a careful observation of the effect of wearing the beard and of shaving upon the air passages and lungs. And I could, if space allowed, record many cases of throat and lung-diseases that have been permanently cured by wearing a beard.”
5) Blemish-Free Skin
Forgoing the razor doesn’t just hide blemishes—it actually prevents them. “Razor rash, acne, and folliculitis [hair-follicle inflammation] are often the result of shaving,” says Shannon C. Trotter, D.O., a fellow of the Osteopathic College of Dermatology and a dermatologist at the Ohio State Wexner Medical Center. “Razors can irritate the skin or even spread bacteria, causing an infection of the hair follicle.”
6) Natural Moisture
You probably didn’t know your face has its own built-in moisturizing regimen—it’s called your sebaceous glands (oil glands for short) and, according to Trotter, it secretes a natural oil that keeps skin moisturized. A thick beard not only prevents you from rubbing it off of your face, it also protects the face from wind exposure, which leads to redness and dryness (just in case you were planning your next high-altitude climb).
7) Trapped Allergens
Your nose hairs trap more than you think they do. In addition to what you see in a tissue, nose hairs trap pollutants that could actually cause your body harm. So the more hair you have under your airways (read: the bigger your beard), the more pollutants you’re snaring every day, according to Clifford W. Bassett, M.D., Allergy and Asthma Care of NY medical director. Just be sure to treat your beard like any other filter and wash it regularly.
8) Prevents Skin Cancer
Recent researches have shown that 95 per cent of UV rays from the sun are blocked by beards. Besides keeping the sun out of your face, this is also important as exposure to UV rays can cause cancer. The thicker the hair, the better!
9) Fights infection
You never have to worry about bacterial infections, ingrowths and folliculitis (infection of the hair follicles, causing spots) with a beard. These infections are occupational hazards of regular shaving. Be done with that, and be done with such problems as well!
10) Keeps you younger
This is an ironic health benefit, since having a beard tends to make you look much older. But actually, by protecting your face from sun damage and blemishes, your beard keeps your skin much younger.
