Weekly Health Quiz: Teeth Grinding, Cortisol Reset, Gut Bacteria, and Safe Strength Training
1 Which daily practice can help relax your jaw and reduce nighttime teeth grinding?
- Drinking green tea in the evening
- Skipping sleep so you grind less at night
- Clenching your jaw during the day to strengthen it
- Using hot compresses and jaw stretches
Hot compresses and jaw stretches directly release tension and retrain your nervous system to stop clenching and grinding. Learn more.
2 What’s one everyday habit that can raise cortisol instead of lowering it?
- Drinking wine with friends on stressful days
- Drinking energy drinks after a healthy meal
- Drinking coffee on an empty stomach
Coffee on an empty stomach spikes cortisol, keeping your body in stress mode instead of helping it reset. Learn more.
- Taking a morning walk in the sun
3 Why can eating too much fiber too soon backfire if your gut is inflamed?
- It makes you crave more sugar
- It instantly kills beneficial bacteria
- It weakens your gut lining
- It increases toxins and stress hormones
If your gut is damaged, excess fiber worsens fermentation and stress signals; the key is healing first, then reintroducing fiber gradually. Learn more.
4 Why is post-acute withdrawal syndrome (PAWS) often misdiagnosed as a relapse of depression?
- They have identical timing to depression
- PAWS symptoms have distinct symptoms
PAWS has its own pattern, but doctors often confuse it with depression returning, leading to misdiagnosis. Learn more.
- Doctors don’t believe withdrawal exists
- Relapse always follows stopping antidepressants
5 Why is DMSO considered such a strong partner for natural therapies?
- It crosses cell membranes and carries other compounds
DMSO’s ability to cross membranes and transport other compounds makes therapies more effective, even against resistant infections or cancers. Learn more.
- It blocks nutrients from reaching the blood vessels
- It prevents vitamins from being used in the intestines
- It stops all drug activity to limit possible reactions
6 What makes blood flow restriction (BFR) training especially valuable for older adults or those recovering from injury?
- It lowers metabolism so recovery is easier
- It eliminates the need for any exercise
- It allows strength gains with lighter weights
BFR activates muscle fibers with light loads, protecting joints while still stimulating strength and muscle growth. Learn more.
- It only works if you lift your maximum weight
7 How does molecular hydrogen act as a redox modulator in the body?
- It lowers harmful hydroxyl radicals while leaving vital signals intact
Hydrogen is selective — it reduces damaging hydroxyl radicals without wiping out important signaling molecules, helping restore balance instead of overcorrecting. Learn more.
- It blocks mitochondrial stress by stopping normal energy pathways
- It shuts down all free radicals so no oxidative stress can occur
- It increases electron buildup so the cell can store more reducing power

6 According to research, what small change in your walking pace can help reverse age-related frailty?
- Adding about 14 extra steps per minute to your usual pace
A study found that adding roughly 14 steps per minute to your normal walking speed significantly improved mobility and endurance in older adults. Learn more.

9 What did the Tokyo study find about vitamin C’s effect on skin thickness?
- It helped in melting shallow fat cells
- It had no impact on cell turnover
- It thickened the living skin layer while improving renewal
Vitamin C boosted the inner living layer of the skin while refining the outer dead cell layer, supporting healthier turnover. Learn more.
- It caused the skin to lose hydration
10 What simple form of exercise can you start with to improve mental health while coming off antidepressants?

17 Why can processed plant-based “meat” alternatives raise your risk of heart disease?
- They often contain hidden sugars that spike insulin
- They contain glyphosate residues and inflammatory oils
Many plant-based “meats” are ultraprocessed, with glyphosate contamination and omega-6 oils like linoleic acid that fuel inflammation and harm heart health. Learn more.

- Hydrogen water provides higher, longer-lasting blood levels than inhalation
- Inhaled hydrogen reacts with oxygen to form antioxidants inside your lungs
- Drinking water bypasses the liver, while inhalation does not
- Inhalation delivers higher concentrations directly into the bloodstream and tissues
When inhaled, hydrogen enters circulation quickly and at higher levels than water alone, making it a stronger systemic option. Learn more.
20 What’s a smarter way to manage constipation after hernia surgery without stressing your gut?
