How to fix lag in this script It runs a loop to check if a player died?

local Player = game.Players.LocalPlayer
local RepStorage = game:GetService("ReplicatedStorage")
local Remote = RepStorage:WaitForChild("DeathRemote")

local function FireRemote()
Remote:FireServer()
end

while true do 
	wait(1)
	if game.Players.LocalPlayer.Character.Humanoid.Health <= 0 then
		FireRemote()
	end
end


-- how i wanted to fix it
Player.Character.Humanoid.Health.Changed:Connect(function()
	print("Health Changed!")
end)

So this runs a loop every second to check if a player has died this can cause lag , I already have experienced lag currently im doing some lag work for my game can someone help me?
