TouchEnded firing while still touching a part?

I have a script inside of an invisible part that detects when a player is inside of it and sets a BodyForce in the Torso of the player from (0, 0, 0) to (0, -200, 0). This script works alongside another that sets the NumberValues named "Heat" and "Oxygen" inside of the player to 65 and 100. When you enter the part the Touched event fires as normal but after doing so much as jumping, the TouchEnded event fires and resets the values. I have tested the scripts inside of a very large part that will always be touching the player at any given time and the problem still occurs.

Here are the two scripts:

The Heat script

local part = script.Parent


local debounce = false

part.Touched:Connect(function(hit)
	if debounce == false then
		debounce = true
		
		local hum = hit.Parent:FindFirstChild('Humanoid')
		
		if hum and hit.Name == "UpperTorso" then
			if hum.Health > 0 then
				
				local Oxygen = game.Players:GetPlayerFromCharacter(hit.Parent):WaitForChild("Oxygen")
				local Heat = game.Players:GetPlayerFromCharacter(hit.Parent):WaitForChild("Heat")
				
				if Heat and Oxygen then
					Heat.Value = 65
					Oxygen.Value = 100
				end
			end
		end
		debounce = false
	end
end)


part.TouchEnded:Connect(function(hit)
	if debounce == false then
		debounce = true
		
		local hum = hit.Parent:FindFirstChild('Humanoid')
		
		if hum and hit.Name == "UpperTorso" then
			if hum.Health > 0 then
				
				local Oxygen = game.Players:GetPlayerFromCharacter(hit.Parent):WaitForChild("Oxygen")
				local Heat = game.Players:GetPlayerFromCharacter(hit.Parent):WaitForChild("Heat")
				
				if Heat and Oxygen then
					Heat.Value = -455
					Oxygen.Value = 0
				end
			end
		end
		debounce = false
	end
end)

and the Gravity script

local part = script.Parent
local debounce = false

part.Touched:Connect(function(hit)
	if debounce == false then
		debounce = true
		
		local hum = hit.Parent:FindFirstChild('Humanoid')
		
		if hum and hit.Name == "UpperTorso" then
			if hum.Health > 0 then
				
				local Gravity = hit.Parent.UpperTorso:FindFirstChild("GravityForce").Force
				if Gravity then
					if Gravity ~= Vector3.new(0, -200, 0) then
						 Gravity = Vector3.new(0, -200, 0) 
					end
				end
			end
		end
		
		debounce = false
	end
end)



part.TouchEnded:Connect(function(hit)
	if debounce == false then
		debounce = true
		
		local hum = hit.Parent:FindFirstChild('Humanoid')
		
		if hum and hit.Name == "UpperTorso" then
			
			if hum.Health > 0 then
				local Gravity = hit.Parent.UpperTorso:FindFirstChild("GravityForce").Force
				if Gravity then
					if Gravity ~= Vector3.new(0, 0, 0) then
						 Gravity = Vector3.new(0, 0, 0)
					end
				end
			end
		end
		
		debounce = false
	end
end)
