Protecting Your Skin: Risks of Smoking and UV Exposure

Skin health is a significant concern for many, reflected in the multi-billion dollar skincare industry. Common skin issues can arise from lifestyle habits, notably smoking and excessive sun exposure. Smoking accelerates aging and skin diseases, while UV light causes damage and skin cancers. Preventative measures are essential for maintaining skin health.

How smoking and sun affect skin’s look and feel

Skin health and beauty- big business

Browse social media or news sites online and you notice skin health and appearance is a priority for most people. Sales for skin care and appearance products and services is a multi-billion dollar industry. If you’re on social media, you’ve probably seen posts from friends who are involved in direct selling companies for skin care, maybe you are also.

As a family physician, I treated skin problems frequently. Some of these are primary skin problems, but some are the result of lifestyle habits, other medical conditions, and even medical treatments. While some of these may be unavoidable, others are preventable.

This post will look at two avoidable risks to skin health and appearance-smoking and ultraviolet light. 

Skin Deep- cells and layers

First let’s take a deeper look at our skin, it’s more complex than you may realize. It has two layers-

the top layer, the epidermis

the lower layer, the dermis

Skin disease and trauma involve damage to one or both layers of the skin- the dermis or epidermis, or to the individual cells- squamous cells, basal cells, or the melanocytes-the cells with pigment that give our skin color.

Cancers can develop in any cell of the skin. Melanoma is cancer of the melanocytes.

Smoking and Your Skin

I’ve previously discussed 7 reasons to be smoke free. One of those is skin health.

By decreasing circulation, smoking robs skin of nourishment and oxygen; this weakens skin , making it susceptible to infection, cancer, and aging.

Skin experts wrote in the Journal of Dermatological Science

“Smoking is associated with many dermatological (skin) conditions, including

  • poor wound healing,
  • premature skin aging,
  • squamous cell carcinoma and melanoma,(cancers)
  • acne,
  • psoriasis, and
  • hair loss

Tobacco’s Effect on  Skin

  • Facial wrinkles and furrows (eg, crows’ feet at corners of the eyes,  smoker’s lines around lips)
  • Baggy eyelids and slack jawline
  • Uneven skin coloring: grayish, yellow with prominent blood vessels (telangiectasia)
  • Dry, coarse skin.

Long term, the skin of a 40-year-old heavy smoker will resemble that of non-smoking 70-year-old. !

Other potential hazards from tobacco use include

  • increased risk for bacterial, yeast, and viral skin infections
  • impaired circulation increasing the risk of frostbite, Raynaud’s syndrome, and blood clots (thrombosis)
  • thrush and gingivitis

Tips to Become Smoke Free

  • Know what triggers you to smoke. Do you smoke after a meal, while driving, or when you’re stressed? Make a plan to handle each trigger.
  • Consider getting support from 1–800–QUIT–NOW or smokefree.gov
  • You can buy nicotine gum, patches, and lozenges from a drug store.
  • Remove cigarettes, ashtrays, and lighters from your home, office, and car.
  • Remind yourself of the benefits of quitting.
  • Even if you start smoking regularly again, don’t give up. Most people who smoke need a few tries to quit before finally being successful.
  • Talk to your healthcare provider about other resources to help you quit.

Ultraviolet Light Effects on Skin

Basking in sunlight may enhance our mood, but too much can damage our skin.

The signs of photo-aging are obvious to physicians-

  • yellowing or sallowing of the skin complexion
  • dry and rough texture with wrinkling,
  • unevenly pigmented skin tone with dilated blood vessels.
  • stretched out
  • easy bruising

Photoaging

Photoaging is premature aging of the skin caused by repeated exposure to ultraviolet radiation (UV), primarily from the sun but also from artificial UV sources, such as tanning beds. Besides aging, excess sun exposure can cause

  • Burns
  • Rash due to increased sun sensitivity when taking certain medications
  • Cancers- skin cancers are the most common type of cancer.

How to Limit UV Light Exposure 

  • Use a broad spectrum sunscreen, SPF 15 or higher
  • Wear hats, sunglasses, sun protective clothing
  • Avoid sun exposure, especially from 10 am to 4 pm
  • No tanning bed use.

When selecting a sunscreen, make sure the label says:

  • Broad spectrum: The words “broad spectrum” means that the sunscreen can protect your skin from both types of harmful UV rays — the UVA rays and the UVB rays.
  • SPF 30 or higher: The American Academy of Dermatology recommends that you select a sunscreen with an SPF rating of 30 or higher.
  • Water resistant: Dermatologists also recommend that you look for the words “water resistant.” This tells you that the sunscreen will stay on wet or sweaty skin for a while before you need to reapply. Water resistance lasts either 40 or 80 minutes. Not all sunscreens offer water resistance.

7 Keys to a Healthy Heart

February is American Heart Month, highlighting heart health amidst Valentine’s Day. In this post I outline seven major types of heart diseases and risk factors such as smoking and hypertension. Recognizing heart problem symptoms is crucial. Maintaining heart health involves addressing risk factors with healthy lifestyle choices. Share this vital information.

February is American Heart Month and has Valentine’s Day, February 14. So, let’s explore our hearts and how we can keep them healthy.

At this previous post you can learn about the HEART’S  anatomy and how it works.

diagram of the human heart
Heart diseases affect any and sometimes multiple parts of the heart- the atria, ventricles, the valves, the aorta, the pulmonary artery and veins, the walls and the coronary arteries (not shown in this diagram. )

In this post I reviewed common heart disorders.

7 Major Types of HEART DISEASE.

  1. Congenital heart disease (problems present at birth)
  2. Cardiomyopathy- disease of the heart muscle
  3. Coronary artery disease/myocardial infarction ( heart attack)- the most common cause of death in the United States
  4. Congestive heart failure
  5. Sudden cardiac death
  6. Arrhythmia-irregular heart beats
  7. Hypertension- high blood pressure
electrocardiogram- tracing
An electrocardiogram, EKG, records the heart beats produced by the heart’s electrical system.

Protecting our HEARTS from Disease, Disability, and Death. 

7 major risk factors for heart disease 

  1. smoking
  2. hypertension
  3. excess body weight
  4. sedentary lifestyle, too little physical activity
  5. high blood fats (cholesterol)
  6. high blood sugar (glucose)
  7. poor nutrition
complications of high blood pressure

Other Risk Factors 

  • Gender– unfortunately males are somewhat more at risk, especially at younger ages.
  • Age– our risk increases as our age does.
  • Ethnicity– some ethnic groups have a higher risk. In the United States these are African Americans, Native Americans, Hispanics.
  • Family history– This means a close relative, like a parent or sibling, who developed heart disease young, or less than 50 years old.

Recognizing that you may have a heart problem can be the first step to getting effective treatment. Here are

7 Keys to a Healthy Heart-Watercress Words.com

7 Symptoms of a Heart Problem

  1. Chest pain– this is probably the most recognized heart disease symptoms, but is not unique to heart disease, nor is it always found in heart disease.
  2. Shortness of breath– especially if it occurs with minimal exertion, or if you find you have less tolerance for exertion.
  3. Palpitations– this means feeling like your heart is beating too fast, too hard, or at irregular intervals.
  4. Fatigue- especially if out of proportion to physical activity, if you tire more easily or quickly, or seem to have less energy than in the past
  5. Unexplained weight gain or swelling in the feet and legs
  6. Dizziness or lightheadedness when standing or walking, especially after exertion.
  7. Syncope, the medical term for fainting or passing out, especially if no other obvious cause (some people know they faint at the sight of blood, or with certain smells; that form of fainting is usually harmless, unless injured from falling)

How to keep Your HEART healthy

Keeping our hearts healthy involves changing the first 7 risk factors I mentioned, which doctors often call modifiable risk factors.

  1. Stop smoking– consider these  7 surprising reasons to be smoke free
  2. Control your weight– achieve and stay at a healthy weight.6 steps to losing weight and gaining hope
  3. Be screened for diabetes and high cholesterol; if found, manage with your doctor’s supervision .10 Silent Signs of Diabetes
  4. Get more active, do some physical activity on a regular basis.Health lessons from the Women’s World Cup
  5. Eat less junk food, make healthier food choices. Learn easy ways to shop healthier from the American Heart Association
  6. Have your blood pressure checked regularly (ask your doctor how often). If you have hypertension,  follow your doctor’s management plan, which may include medication. Learn more from FamilyDoctor.org 
  7. Control and manage stress. Medical studies suggest that emotional stress can bring on cardiovascular disease. You can learn more from Dr. James Marroquin’s fascinating post.
