Chef de catarat prin munti si vai?

Atunci te invit sa citesti si sa respecti Codul international de semnalizare pe munte in caz de pericol. Acest cod a fost adoptat de Congresul Uniunii Internationale a Asociatiilor Alpine (U.I.A.A.), care a avut loc la Paris in 1937 si este folosit de turistii din intreaga lume.

Semnalele emise in caz de pericol sunt de trei feluri: luminoase, vizuale si acustice.
1. semnalele luminoase: Noaptea se lanseaza cu ajutorul unei lanterne, a unui felinar, a unui foc de tabara, primus, etc, iar ziua cu ajutorul unei oglinzi.
2. semnale vizuale: In afara de semnalele luminoase, se pot executa semnale vizuale prin fluturarea unei esarfe sau a altor obiecte de imbracaminte.
3. semnale acustice: Strigate, fluieraturi, lovirea unor obiecte metalice (piolet, bete de cort, ceaun, linguri, farfurii de tabla, etc).
Se lanseaza cate 6 semnale, din 10 in 10 secunde, timp de un minut; intre grupurile de 67 semnale se face o pauza de un minut. Pentru raspuns se utilizeaza 3 semnale pe minut, urmand un minut de pauza.

In cazul in care turistul aflat in stare de pericol se afla intr-un refugiu alpin sau in vecinatatea lui, da alarma ridicand fanionul rosu, aflat obligatoriu in dotarea adapostului. Toate cabanele trebuie sa aiba in dotare trusa medicala si sa constituie, in caz de accident, puncte de anuntare pentru interventii salvamont.

Recomandari
Traseele trebuie alese in functie de experienta si pregatirea voastra; documentati-va asupra traseului pe care urmeaza sa-l parcurgeti;

Discutati cu cabanierii, padurarii, ciobanii despre starea traseului (despre poteci, podete, marcaje, poteci si puncte de salvamont);

Nu plecati in drumetie daca sunteti obosit sau daca va aflati in convalescenta;

Incercati sa aveti un pas regulat, deoarece mersul grabit si inconstant duce la epuizarea resurselor de energie intr-un timp foarte scurt;

Nu consumati bauturi alcoolice inainte sau in timpul excursiei, caci slabesc organismul, iarna favorizand inghetul; de preferinta, nu fumati in timpul excursiei;

Informati-va asupra prognozei meteo pentru cel putin 24 de ore si evitati drumetiile pe vreme nefavorabila;

In caz de furtuna sau ploaie cu descarcari electice, parasiti culmea si nu va adapostiti langa copaci izolati, inalti sau langa stanci, care ar putea atrage traznetele;

In caz de ceata, ploaie puternica sau viscol, cautati urgent un adapost;

Evitati strigatele si zgomotele puternice in zonele unde se pot produce avalanse;

Folositi incaltaminte si imbracaminte adecvate anotimpului si traseului pe care il veti parcurge;

Nu incarcati rucsacul peste limite rezonabile;

Luati de preferinta o harta si o busola si, neaparat, trusa medicala;

Nu faceti focul in padure; nu aruncati chibrituri sau tigari aprinse;

La plecarea dintr-un popas lasati curat in urma voastra.

4 ore - corpul, o enciclopedie de informatii vitale pentru tine.

Să ne lămurim: nu sunt nici medic, nici doctor în ştiinţe.

Sunt un strângător meticulos de date cu acces la mulți dintre cei mai buni atleți și oameni de știință ai lumii.

Asta mă pune într-o poziție destul de neobișnuită.

Pot să trag învățăminte din discipline și subculturi care rareori intră în contact și pot să testez diverse ipoteze folosind un tip de autoexperimentare pe care specialiștii din cadrul instituţiilor nu îl pot aproba (deși ajutorul lor din spatele scenei este crucial).

Punând sub semnul întrebării premise fundamentale, este posibil să dai peste soluții simple și neobișnuite la probleme foarte vechi.

Grăsime în plus? Încearcă proteine luate programat și suc de lămâie înainte de mese.

Prea puțini mușchi? Încearcă ghimbir și varză acră.

Nu poți dormi? Încearcă să îți crești grăsimea saturată sau să te expui la frig.

Această carte include descoperirile a mai bine de 100 de doctori în diferite domenii, oameni de știință de la NASA, medici, atleți olimpici, antrenori profesioniști (de la NFL la MLB), deținători de recorduri mondiale, specialiști înreabilitare de la Super Bowl și chiar foști antrenori din Blocul de Est.

Vei întâlni unele dintre cele mai incredibile specimene pe care le-ai văzut vreodată, inclusiv transformări înainte-și-după.

Nu am de păstrat o carieră academică de tipul „ori publici, ori ești mort” și acesta este un lucru bun.

După cum mi-a spus un medic de la o cunoscută universitate de top, în timp ce luam prânzul: "Suntem antrenați timp de 20 de ani să avem aversiune față de risc. Mi-ar plăcea să experimentez, dar aș risca tot ce am construit în peste două decenii de școală și pregătire. Aș avea nevoie de un colier care să-mi dea imunitate. Universitatea nu ar tolera niciodată aşa ceva".

Apoi a adăugat: „Tu ai putea fi «calul negru»”.
