Understanding Your Lifestyle Habits and How They Affect Your Skin Health

Your skin shares a blood supply, a hormonal system, and an immune response with the rest of your body. When something is off internally, your skin registers it. A stretch of bad sleep or a high-stress month can push acne, eczema, or rosacea from stable into a full flare that doesn’t match anything you changed in your routine.

At Hines Dermatology Associates in Attleboro, Massachusetts, Yvonne Hines, MD, and our clinical team treat chronic skin conditions daily. We see a lot of patients who are doing everything right with their skincare, but still flaring because something in their daily routine is fueling the problem.

Stress and your skin’s inflammatory response

Chronic stress keeps your cortisol elevated, which increases oil production, weakens your skin barrier, and amplifies the inflammatory response behind conditions like eczema, rosacea, and psoriasis. Studies have consistently shown that patients with inflammatory skin conditions report worse flare-ups during periods of high stress, even when their treatment stays the same.

A visible flare creates frustration and self-consciousness, which raises cortisol further, which makes the flare worse. Conditions most reactive to stress include:

• Acne breakouts 
• Eczema patches 
• Rosacea flushing 
• Psoriasis plaques 
• Hair shedding, known as telogen effluvium

That’s why managing stress is sometimes part of the treatment plan, not a replacement for topical care.

Sleep and skin barrier recovery

Your body does most of its cellular repair during sleep. Blood flow to the skin increases, collagen production picks up, and damage from ultraviolet (UV) radiation gets addressed at the cellular level. Falling short consistently, whether that means fewer hours, poor quality, or irregular timing, slows that repair process and keeps your barrier compromised longer.

Sleep deprivation also raises cortisol, creating the same cortisol-driven problems that chronic stress does. For people with rosacea, poor sleep can make your skin more sensitive, so triggers that usually wouldn’t bother you may suddenly cause a flare-up. 

For eczema patients, a weaker barrier means more nighttime itching, which disrupts sleep further and keeps the whole cycle going.

Diet and specific skin conditions

Diet affects skin through blood sugar regulation, gut health, and systemic inflammation, and different conditions respond to different triggers.

Acne

Foods that spike blood sugar quickly, like white bread, sugary drinks, and processed snacks, trigger a surge of insulin and insulin-like growth factor 1 (IGF-1) that increases sebum production. 

A 2022 systematic review out of Johns Hopkins found that high-glycemic diets had a consistent association with worse acne across multiple randomized controlled trials. 

Eczema

An imbalanced gut microbiome, common with diets low in fiber and high in processed food, increases systemic inflammation that can intensify eczema flares. 

Rosacea

Rosacea flares can start within minutes of consuming certain triggers. The most common ones include:

• Alcohol, particularly red wine and beer
• Spicy foods
• Hot beverages like coffee and tea
• Foods high in cinnamaldehyde, including cinnamon, tomatoes, and citrus

A simple food journal during active flare-ups helps narrow down the ones that matter for you.

When to bring this up with your dermatologist

If your skin keeps flaring despite consistent treatment, Dr. Hines can evaluate whether stress, sleep, or diet is contributing and adjust your plan accordingly.
