How We Feel vs Sauna Suit

The essential hydration tool for athletes who cut weight. Sauna Suit Hydration Protocol is built for combat sport athletes, bodybuilders, and fitness competitors who train in sauna suits to drop water weight before weigh-in, photoshoots, or competition. Whether you're a pro fighter making weight or a gym-goer exploring heat training, this app gives you the numbers you need to cut effectively without compromising health or performance. PERSONALIZED SWEAT RATE CALCULATION Enter your body weight, height, age, biological sex, fitness level, workout intensity, and sauna suit type. The app instantly calculates your personal sweat rate using published sports science — drawing on ACSM guidelines, peer-reviewed sauna suit research, and sweat composition data from sports dietetics. No more guessing. No more generic advice. Just numbers built around your body. REAL-TIME DEHYDRATION RISK MONITORING A dynamic safety gauge shows exactly where you sit on the dehydration scale as you adjust your session. The app flags when you approach the 2% body weight threshold where performance drops, the 5% mark where work capacity falls by 30%, and the critical zones beyond. Color-coded warnings tell you immediately when a session is too long or too intense. COMPLETE HYDRATION TIMELINE Know exactly what to drink, when, and how much: • Pre-session hydration targets • Sip-by-sip intake during training (every 15 minutes) • Post-session rehydration to replace deficits • Electrolyte replacement: sodium, potassium, magnesium, calcium Built on the 150% rehydration principle used by professional sports dietitians. SAFE MAXIMUM DURATION The app calculates your personal safe training ceiling based on your stats and your planned session. It tells you when to stop — before your body does. SESSION LOG (Registered Users) Track real-world results. Log pre-session and post-session weights, hydration intake during training, and next-morning weight to measure overnight recovery. Over time, your personal dataset reveals exactly how your body responds to different cut protocols — making every subsequent cut smarter than the last. CONTRIBUTE TO ATHLETIC RESEARCH All personal data is stored securely. Anonymized, non-identifiable session data optionally contributes to ongoing research aimed at improving sweat rate calculation accuracy for the broader athletic community. Your cut helps the next athlete cut smarter. DESIGNED FOR THE CUT ENVIRONMENT High-contrast dark interface built for locker rooms, cut sessions, and weigh-in prep. Quick adjustments under pressure. No unnecessary taps, no fluff — just the numbers you need when minutes matter. SCIENCE-BACKED, NOT HYPE Built on research from: • American College of Sports Medicine (ACSM) Position Stand on Exercise & Fluid Replacement • Wilmott et al., Temperature Journal (2018) — sauna suit physiological strain • Dalleck et al., ACE-sponsored sauna suit research • Gatorade Sports Science Institute sweat testing methodology • Precision Hydration athlete data IMPORTANT HEALTH NOTICE Sauna suit training carries real risks. This app provides estimates only and is not a substitute for medical advice. Consult a physician before beginning sauna suit training — especially if you have heart, kidney, or blood pressure conditions. Not recommended for diabetics, pregnant women, individuals under 18, or elderly users without medical supervision. Cut smart. Recover smarter. Train safer.
