Help me understand and resolve a recent issue I’ve had with muscle cramps. As I wake up in the morning in bed, I involuntarily stretch my whole body, and recently my calves will seize up and immediately cramp with painful knots that take several minutes to release. Even later in the day, I can feel they haven’t fully released. What could have triggered this to begin happening, and how can I avoid it? I’m moderately athletic, and I run about a mile a day. I’m 47, male, 147lb.

While there weren't any specific clips found directly addressing morning calf cramps from involuntary stretching, Andrew Huberman has discussed muscle cramps and related issues in the past, focusing on potential causes and preventive measures.

Potential Triggers:

1. Dehydration: Lack of proper hydration can lead to muscle cramps. Ensure you're drinking enough water throughout the day, especially if you're active.
2. Electrolyte Imbalances: Deficiencies in key electrolytes like potassium, magnesium, and calcium can cause cramps. A balanced diet or supplementation might be necessary.
3. Overuse or Strain: Your running routine, even at a mile a day, could contribute if your muscles aren't recovering properly.
4. Lack of Stretching: Inadequate stretching before and after exercise can result in muscle tightness, which may manifest as cramps.

Preventive Measures:

1. Hydration: Increase your water intake. Consider electrolyte-rich drinks if you sweat a lot.
2. Diet: Incorporate foods high in potassium (bananas), magnesium (nuts, spinach), and calcium (dairy products).
3. Stretching: Implement a stretching routine targeting your calves, both before bed and after waking up.
4. Massage and Warmth: Gentle massage of the affected areas and applying warm packs can help the muscles relax.

Consult a healthcare professional if the problem persists, as it could indicate underlying health issues. These steps should offer some immediate relief and help prevent future cramps.
