To determine if water is safe to drink, follow these actionable steps depending on your water source:
To ensure your drinking water is safe, testing is necessary because many dangerous contaminants—like lead, arsenic, and bacteria—are invisible and odorless. The most accurate approach is to use a state-certified laboratory, though you can also use home test kits for a quick initial screening.
On Zepbound, you should aim to drink at least 64 to 100 ounces (2 to 3 liters) of water daily. Proper hydration is crucial on GLP-1 medications to help minimize common gastrointestinal side effects like constipation and to support your body's metabolic processes.
Moreover, increasing total daily fluid intake by ∼1.5–2 L of fluid per day in participants with low habitual fluid intake reduced saliva cortisol in a single morning measurement (23).
Hyponatremia caused by too much water, also known as water intoxication, happens when you consume water faster than your kidneys can excrete it (about 0.8−1.0 liters per hour). This dilutes the sodium levels in your blood, causing your cells, including brain cells, to swell and trigger dangerous neurological symptoms.
The 10-gulp rule is a hydration habit designed to help you easily meet your daily water intake goals. The rule is simple: Every time your water bottle or glass touches your lips, take exactly 10 large gulps before putting it down.
Hyponatremia signs and symptoms may include: Nausea and vomiting. Headache. Confusion.
This rise in hormones changes your appetite. You do not usually crave broccoli or grilled fish when you are stressed. Instead, you want foods that give you fast energy or make you feel comforted. Most people crave sugar, salt, and fat when their cortisol stays high for too long.
When cortisol (the primary stress hormone) remains elevated for too long, it impacts your metabolism, blood pressure, and immune system. Here are 10 common warning signs of chronically high cortisol levels:
The five primary signs of dehydration include dark-colored urine, extreme thirst, dry mouth or lips, fatigue, and dizziness or lightheadedness.
Kelly Clarkson’s weight loss was achieved through a combination of using a prescription weight-loss medication, following doctor-ordered dietary changes (high protein), and significantly increasing her daily activity through walking after moving to New York City. She noted that she was pre-diabetic and made these changes for her health.
Drinking water does not directly lower your A1C, but it is an essential tool for managing it. Proper hydration prevents your blood glucose from concentrating and helps your kidneys naturally flush out excess sugar through your urine.
An early symptom to look out for is thirst, which is your body's way of telling you that you need to drink water or other fluids. Another sign is when your pee becomes darker than usual. Other signs of dehydration include: feeling dizzy or lightheaded.

Yes, you can test your tap water at home using DIY test kits or professional mail-in lab services.
Your tap water should not smell and should be clear - if it is not, contact your water company, or local council if you have a private water supply.
Research links high cortisol levels to Vitamin D and Vitamin C deficiencies. Additionally, a lack of Vitamin B12 is associated with an exaggerated stress response and elevated cortisol during chronic stress.
High cortisol (hypercortisolism) creates a persistent "fight-or-flight" state. It typically feels like a mix of intense physical stress and emotional exhaustion. Symptoms include severe anxiety, insomnia or waking up abruptly at night, brain fog, abdominal weight gain, muscle weakness, and easy bruising.
Testing cortisol levels at home is usually done using an at-home saliva or finger-prick blood kit, where you collect samples and mail them to a laboratory for analysis. These kits measure your active "free" cortisol or track your daily stress hormone rhythm.
Cortisol-Triggering Foods
Refined sugars and processed foods can cause spikes in blood sugar, which can result in the release of cortisol. Foods high in saturated and trans fats can promote inflammation and lead to obesity.
Cortisol-lowering drinks are functional beverages designed to reduce stress hormones. While no single drink is a magic cure-all, hydration with electrolytes, green tea, and calming adaptogenic ingredients can support your adrenal system.
Symptoms of Cortisol Addiction
Low sodium (hyponatremia) can make you feel extremely fatigued, dizzy, and nauseous. Because sodium balances the fluids in your cells, a drop in levels causes fluid to move into the brain, resulting in headaches, confusion, muscle weakness, or painful cramps.

Diseases cause dehydration in adults primarily by triggering excessive fluid loss, reducing fluid intake, or altering how the kidneys retain water. Common culprits include diabetes, gastrointestinal infections, and kidney or autoimmune disorders.
