2. Prioritizing Sleep

Dr. Funato believes that sufficient, consistent sleep is a key factor in cancer prevention. His recommendations include:

• Regular sleep schedule: Going to bed at 10 p.m. and waking up at 6 a.m.

• A minimum of six hours of sleep: Ensuring proper rest each night.

• Avoiding late nights: Not staying up past midnight.

Dr. Funato emphasizes that quality sleep enhances immune function, which is essential for preventing cancer recurrence.

3. Regular Physical Activity

Following his surgery, Dr. Funato committed to walking at least 3,000 steps every day. His advice for cancer prevention through exercise includes:

• Regular physical activity: Engaging in daily movement routines.

• Raising body temperature: Walking and other activities can raise the body’s temperature, boosting immune cell activity.

• Increasing oxygen intake: Exercise improves oxygen circulation, which may help reduce cancer cell growth.

Physical activity is also beneficial for lowering blood sugar levels, thus depriving cancer cells of their main source of energy.

4. Maintaining Body Warmth

Dr. Funato believes that cancer cells thrive in cooler body temperatures. To combat this, he focuses on:

• Keeping his body warm: Especially during the colder months.

• Focusing on warming the abdomen and lower body: Areas where cancer is more likely to develop.

Dr. Funato explains that a warm body boosts immune function and helps produce heat shock proteins that assist in cellular repair.

5. Embracing Laughter

Dr. Funato highlights the importance of laughter for cancer patients, stating:

• Laughter reduces stress: It helps alleviate negative emotions.

• Intentional smiling: Even if one cannot laugh, deliberately smiling can lift the mood.

He encourages individuals to integrate laughter into their daily routine as a simple and effective stress-relief practice.
