Sweat and Your Health in Grand Rapids, Michigan

Sweating is a normal and important body function, especially in a city like Grand Rapids, MI, where residents experience humid summers and very cold winters. Understanding how sweat works can help you manage common issues like excessive sweating (hyperhidrosis) or reduced sweating (hypohidrosis), and know when to see a doctor at local health systems such as Spectrum Health, Trinity Health Grand Rapids, Metro Health, or Mercy Health.

What Is Sweat?

Sweat is produced by sweat glands located in the deeper layer of the skin (the dermis). These glands are found all over the body, but are most numerous on:

  • Forehead
  • Armpits
  • Palms of the hands
  • Soles of the feet

What Is Sweat Made Of?

Sweat is mainly water, but it also contains:

  • Salts (especially sodium and chloride)
  • Small amounts of other minerals and waste products

Because Michigan summers can be humid—especially around the Grand River and Greater Grand Rapids area—sweat may not evaporate as quickly, making you feel hotter and stickier than the actual temperature suggests.

Why Do We Sweat?

Temperature Control

The main function of sweat is to control body temperature. When your body gets too warm:

  1. Sweat glands release sweat onto the skin.
  2. As the sweat evaporates, it cools the surface of the skin.
  3. This helps prevent overheating, especially during hot Michigan summer days or when you’re active outdoors on local trails or at Lake Michigan beaches.

Grip and Handling

Sweat also helps slightly moisten the palms, improving grip. This can be helpful during:

  • Physical work
  • Sports and fitness activities at local gyms or parks
  • Handling tools or equipment

Normal Causes of Sweating

Normal, healthy sweating can be triggered by:

  • Hot temperatures (summer heat or overheated indoor environments in winter)
  • Physical exercise
  • Emotional stress or anxiety
  • Eating hot or spicy foods
  • Fever associated with illness (such as infections common in colder months in Grand Rapids)

Excessive Sweating (Hyperhidrosis)

Excessive sweating that is not related to heat or exercise is called hyperhidrosis. This condition can be uncomfortable and socially distressing, and it’s more noticeable in close-contact environments like schools, offices, and churches across Grand Rapids.

Idiopathic Hyperhidrosis

The most common form is idiopathic hyperhidrosis:

  • “Idiopathic” means no clear cause can be found.
  • It can develop during childhood or later in life.
  • It can affect any part of the body, but usually involves:
    • Palms
    • Soles of the feet
    • Armpits

Excessive sweating may:

  • Occur even in cool weather (including Michigan winters)
  • Worsen in warm or humid weather
  • Increase with emotional stress, such as public speaking, interviews, or social events

Causes of Increased Sweating

While many people in Grand Rapids with hyperhidrosis have no identifiable cause, some known triggers and conditions include:

  • Obesity
  • Hormonal changes associated with menopause (hot flushes)
  • Illnesses associated with fever (such as infections)
  • Overactive thyroid gland (hyperthyroidism)
  • Diabetes
  • Certain medications

When Are Tests Needed?

In most cases, no special tests are required to diagnose hyperhidrosis. Occasionally, your Grand Rapids healthcare provider may order:

  • Blood tests for thyroid disease
  • Other tests if an underlying medical condition is suspected

You can start by seeing your primary care doctor, or ask for a referral to a dermatologist at Spectrum Health, Trinity Health Grand Rapids, Metro Health, or Mercy Health.

Treatment for Excessive Sweating in Grand Rapids

Treatment depends on the cause and severity of sweating. Your doctor will help you choose the safest and most effective option.

Topical Treatments (Applied to the Skin)

These are often the first step:

  • Antiperspirants with 10–25% aluminum salts

    • Often available over the counter or by prescription
    • Commonly used in the armpits, but can also be applied (with care) to:
      • Palms
      • Soles
      • Forehead

  • Topical anticholinergic medications

    • May be available as:
      • Cream
      • Spray
      • Powder
      • Stick
      • Roll-on
      • Wipes
      • Paint-on solutions

Always follow instructions carefully and discuss sensitive areas with your doctor or dermatologist.

Oral Medications

  • Oral anticholinergic medications can be prescribed to block activation of sweat glands.
  • These require monitoring by a healthcare provider because of possible side effects (such as dry mouth, blurred vision, or constipation).

Medical Procedures

Performed by specialists (often dermatologists or plastic surgeons) at larger health systems in Grand Rapids:

  • Iontophoresis

    • A low-level electric current is passed through the skin (often hands or feet) in water trays.
    • Temporarily reduces sweat gland activity.

  • Botox (botulinum toxin) injections

    • Used to paralyze sweat glands in areas such as the armpits.
    • Effects from a single treatment usually last 6–9 months.

  • Non-invasive microwave treatment (MiraDry®)

    • FDA-approved for excessive underarm sweating.
    • Uses microwave energy to destroy sweat glands in the armpits.

  • Surgery to nerves that control sweat glands

    • May be considered in severe cases when all other treatments have failed.
    • Usually reserved for very disabling hyperhidrosis and done by specialized surgeons.

Lifestyle Measures and Self-Help Strategies

Some home strategies that can help manage hyperhidrosis in Grand Rapids’ changing seasons include:

  • Wear loose, breathable clothing (cotton or moisture-wicking fabrics).
  • Choose light-colored clothing in summer to stay cooler.
  • Use antiperspirants with aluminum chloride designed for hyperhidrosis; follow directions closely.
  • Change socks regularly and choose moisture-wicking socks if feet sweat heavily.
  • Wear breathable shoes and allow them to dry fully between uses.
  • Manage stress with relaxation techniques, exercise, or counseling if needed.

If sweating is affecting your work, school, or social life, speak with a healthcare provider. Many people in West Michigan live more comfortably after proper treatment.

Reduced Sweating (Hypohidrosis and Anhidrosis)

Reduced sweating is called:

  • Hypohidrosis – partial loss of sweating
  • Anhidrosis – complete lack of sweating

These conditions can be serious because they interfere with your body’s ability to cool itself, especially during summer heat waves in Grand Rapids or intense exercise.

Causes of Reduced Sweating

Possible causes include:

  • Some skin disorders that damage sweat glands
  • Burns to the skin
  • Underactive thyroid (hypothyroidism)
  • Dehydration
  • Certain medications or nerve disorders

Heat Exhaustion and Heat Stroke in Michigan Weather

Even in a northern state like Michigan, heat-related illness is a real risk, especially during humid Grand Rapids summers, outdoor festivals, or sports events.

Heat Exhaustion

Heat exhaustion happens when the body loses too much water and salts through sweat and cannot cool itself properly.

Symptoms can include:

  • Heavy sweating
  • Muscle cramps
  • Headache
  • Nausea
  • Vomiting
  • Weakness or dizziness

Excessive loss of body salts and water can lead to a life-threatening complication if not treated.

What to do:

  • Move to a cool, shaded, or air-conditioned place.
  • Drink plenty of fluids, preferably water or an electrolyte drink.
  • Loosen clothing.
  • Sponge or spray the body with water to help cooling.

If symptoms do not improve quickly, seek urgent medical care at a local Emergency Department or urgent care center in Grand Rapids.

Heat Stroke (Sun Stroke)

Heat stroke is a medical emergency that occurs when the body’s temperature rises rapidly and sweating is not enough to cool it down.

It can occur in:

  • Hot weather when not enough sweat is produced
  • People with anhidrosis or hypohidrosis
  • Intense outdoor activity without adequate hydration

Signs of heat stroke may include:

  • Very high body temperature
  • Hot, red, dry, or damp skin
  • Confusion or altered mental status
  • Rapid pulse
  • Fainting or loss of consciousness

If heat stroke is suspected, call 911 immediately. While waiting for help:

  • Move the person to a cooler place.
  • Cool the body with wet cloths, cool water, or fans.
  • Do not give fluids if the person is unconscious or confused.

When to See a Doctor in Grand Rapids

You should seek medical advice if:

  • You sweat much more than other people in similar conditions.
  • Sweating interferes with work, school, relationships, or daily activities.
  • You have sweating mainly at night (night sweats).
  • You suddenly stop sweating in hot conditions.
  • You have symptoms of heat exhaustion or heat stroke.

Local options include:

  • Your GP / primary care doctor
  • A dermatologist at:
    • Spectrum Health
    • Trinity Health Grand Rapids
    • Metro Health
    • Mercy Health

For public health information and community resources, you can also contact the Kent County Health Department or Grand Rapids Public Health programs.
