Post-sauna hydration means replenishing the fluids and electrolytes
lost through sweating after a sauna session. Water alone is not
always enough, as sweat also removes sodium and other minerals from the body.
Proper hydration supports recovery, alertness, and overall well-being after a sauna.

The temperature of a Finnish sauna is typically 70–90 °C, and
a sauna-goer sweats approximately 0.8–1.2 L/h.

1 liter of sweat contains, on average, approximately:

• 700 mg of sodium
• 700 mg of chloride
• 200 mg of potassium
• 10 mg of magnesium

Sweat contains significantly more sodium compared to other electrolytes.

After 0.5 hours of sweating, electrolyte loss begins to occur to an extent
that the body "reminds" you of it.

Approximately 350-400 mg of sodium is lost in this time, which is already a noticeably palpable amount.

Sodium regulates water absorption.

Without sodium, water is not properly absorbed into the bloodstream but is quickly excreted with urine. This creates a feeling of "drinking but not quenching your thirst." Dehydration impairs recovery.

Low sodium levels = feeling unwell quickly

Sodium deficiency easily causes:

• Headaches
• Weakness
• Fatigue
• Muscle flaccidity
• Heart palpitations

Direct answer:

Water alone is not always enough to replenish the electrolytes lost in the sauna.

Water

• Replenishes fluids
• Does not replace electrolytes

Electrolyte drink

• Replenishes fluids
• Replaces sodium and other minerals
• Supports faster recovery

This post-sauna rehydration powder is an electrolyte powder specifically
designed to replenish fluids and minerals lost through sweating in the sauna.

Features:

• Contains electrolytes
• Mixes with water
• Easy to use and light to carry, even in single-dose packets
• Intended for recovery

This post-sauna rehydration powder is designed for recovery, not for maximizing performance. Sports drinks often also contain carbohydrates (sugars) to replenish energy stores.

Post-sauna hydration is important for everyone, but especially for the following groups:
* Active sauna-goers
* Middle-aged and elderly individuals
* People who experience headaches or
fatigue after sauna

The best time for hydration is immediately after a sauna session or
within 30 minutes at the latest.

Additional notes:
No need to drink while in the sauna
Excessive drinking during a sauna session is not necessary

Yes, for most adults and active individuals.
Exceptions: kidney disease, heart disease, or strict salt intake restrictions – in which case, it's advisable to consult a doctor.

Yes. If you work out and then go to the sauna,
maintaining electrolyte levels will reduce cramps and improve recovery.

Yes, but they are not absorbed as quickly as from a drink.
After sauna bathing and heavy sweating, the body needs rapid rehydration, where
a drink is superior.

Beer (including non-alcoholic) contains some electrolytes, but not enough for effective recovery. Alcohol is also a diuretic, meaning it promotes urine excretion. Diuretics can therefore impair fluid balance.

Not necessarily. One stick pack during or after a sauna
is sufficient for most, but when sweating profusely (e.g., 80–90 °C, long
duration over 30 min), 2 stick packs may be needed.

Mineral water is an excellent drink, but its electrolyte levels in terms of necessary salts are lower than the amounts lost in the sauna. An electrolyte drink is designed specifically to quickly replace these electrolytes lost through sweating.

Sauna generally relaxes, but excessive dehydration can impair sleep quality.
An electrolyte drink supports recovery and helps maintain better fluid balance
in the body.

Yes, you can; the drink contains neither caffeine nor sugar.
