I took it to myself to create it for you. Edit it how you like. (Untested)

pawn Код:

new HealthTimer;
forward RaiseHealth(playerid, Float:Health);

public RaiseHealth(playerid)
{
    new
        Float:Health;
        
    GetPlayerHealth(playerid, Float:Health);
    SetPlayerHealth(playerid, Float:Health+1.00);
    return true;
}

public OnPlayerEnterCheckpoint(playerid)
{
    HealthTimer = SetTimerEx("RaiseHealth", 1000, true, "f", playerid);
    return true;
}

public OnPlayerLeaveCheckpoint(playerid)
{
    KillTimer(HealthTimer);
    return true;
}
