Wellness & Activity

Movement, sleep, and mental health — the parts of CKD care that don't show up on the lab report.

Why movement matters for your kidneys

Exercise doesn’t directly raise your GFR. What it does is improve almost everything CKD makes harder: blood pressure, blood sugar control, cardiovascular risk, bone strength, sleep, mood, and the muscle mass that quietly drains away as kidney disease progresses.

The most common pushback we hear is “I’m too tired or too sick to exercise.” The honest answer: many patients feel better with regular movement, not worse. Start small — smaller than feels worth doing — and build from there.

Exercise by stage

Most relevant:All stages — guidance varies

The right kind and amount of exercise depends on where you are in your kidney journey. Pick your tab:

Exercise guidance by stage

All stages 1–3
The goal
150 minutes a week of moderate aerobic activity, plus two sessions of resistance training. Same as general adult guidelines.
What to watch
No special restrictions for most people. If you have polycystic kidney disease, talk with your team about contact sports.

Where to start

  • • Brisk walking, swimming, cycling, dancing
  • • Resistance bands, bodyweight squats, push-ups
  • • Yoga, tai chi, gardening

Sleep

Most relevant:All stages — more relevant 3–5

  • Restless legs syndrome is very common in CKD. Iron deficiency and uremia both contribute.
  • Sleep apnea is more common in CKD patients, and fluid overload contributes to airway narrowing.
  • Nocturia — waking to urinate — is especially common in early to moderate CKD as the kidneys lose their ability to concentrate urine.
  • Itching can be severe enough at advanced stages to wake patients repeatedly.
  • Anxiety and depression add another layer. A new CKD diagnosis is a lot to carry to bed.

Mental health

Most relevant:All stages — often underscreened

A CKD diagnosis is life-altering. Grief, fear, anger, denial — all of these are normal reactions. They’re also treatable, and left untreated they make the medical part of CKD harder.

The numbers are sobering: depression rates in CKD are significantly higher than in the general population — up to 20–30% in patients on dialysis. Anxiety is common around lab results, progression, mortality, finances, and family impact. And brain fog — difficulty concentrating that’s real and physiological in advanced CKD — gets worse when sleep, anemia, and depression aren’t addressed.

  • Talk about it. With your care team, a therapist, a peer support group, your family. Normalize it out loud.
  • Get screened.Your nephrologist or PCP can screen for depression (PHQ-9) and anxiety (GAD-7). If you haven’t been screened, ask.
  • Therapy. Cognitive behavioral therapy has evidence in CKD populations specifically. Telehealth makes access easier — many therapists see patients by video.
  • Medication when appropriate. Many antidepressants are safe in CKD with proper dose adjustment. SSRIs are commonly used.
  • Peer support. Several kidney organizations offer mentor programs — you can talk to someone who has been through this. It is wildly underused and almost universally helpful.
  • Caregiver support. Family and friends who are walking this road with you carry weight too. Their well-being directly affects yours.

Staying active in daily life

You don’t need a gym. Walking, gardening, stretching, and ordinary household tasks all count. Some ideas that have worked well for our patients:

  • A simple step counter on your phone builds awareness without effort.
  • Walk with someone — a spouse, a neighbor, a grandkid — and it’s social as well as physical.
  • Set one small goal: “I’ll walk for 10 minutes after lunch.” Build from there.
  • On dialysis days, gentle stretching before or after treatment keeps muscles from tightening up.
  • If you can’t stand for long, chair-based exercise routines on video are free and effective.

Ask your care team about:

  • A referral to physical therapy or exercise physiology
  • Whether your dialysis center offers intradialytic exercise
  • Local kidney patient support groups
  • Mental health screening (PHQ-9 and GAD-7) if you haven’t had it

Questions for your next visit

  1. Given my stage and other conditions, are there activities I should avoid?
  2. Could I benefit from a physical therapy or exercise physiology referral?
  3. Have I been screened for depression and anxiety this year?
  4. Are there signs my sleep problems should be evaluated with a sleep study?
  5. Is there a peer mentor program or support group you’d recommend?
